Physiol. 83(4): 1184–1191, 1997.—Because cardiovascular disorders and stroke may induce Cheyne-Stokes respiration, our purpose was to study the interaction among cerebral activity, cerebral circulation, blood pressure, and blood gases during Cheyne-Stokes respiration. Ten patients with heart failure or a previous stroke were investigated during Cheyne-Stokes respiration with recordings of daytime polysomnography, cerebral blood flow velocity, intra-arterial blood pressure, and intra-arterial oxygen saturation with and without oxygen administration. There were simultaneous changes in wakefulness, cerebral blood flow velocity, and respiration with accompanying changes in blood pressure and heart rate ∼10 s later. Cerebral blood flow velocity, blood pressure, and heart rate had a minimum occurrence in apnea and a maximum occurrence during hyperpnea. The apnea-induced oxygen desaturations were diminished during oxygen administration, but the hemodynamic alterations persisted. Oxygen desaturations were more severe and occurred earlier according to intra-arterial measurements than with finger oximetry. It is not possible to explain Cheyne-Stokes respiration by alterations in blood gases and circulatory time alone. Cheyne-Stokes respiration may be characterized as a state of phase-linked cyclic changes in cerebral, respiratory, and cardiovascular functions probably generated by variations in central nervous activity.

✓ Cheyne-Stokes respiration commonly induces a rhythmic pupillary dilatation during hyperpnea and constriction during apnea. Failure of a pupil to dilate during hyperventilation indicates underlying sympathetic nerve paralysis. This report deals with an instance in which one pupil failed to constrict during apnea due to oculomotor nerve compression. The periodic respirations and anisocoria disappeared following surgical evacuation of a large ipsilateral subdural hematoma.

This thesis has investigated the efficacy of non-invasive ventilation in subjects with congestive heart failure (CHF) and Cheyne—Stokes respiration (CSR). The effect of this therapy on sleep, breathing and haemodynamic variables has been examined. This thesis also describes the morphology and magnitude of the blood pressure (BP) and heart rate (HR) oscillations associated with CSR and elucidates contributing factors to the changes observed. Chapter 1 - literature review - outlines the presentation and treatment of CSR in patients with CHF. Cheyne-Stokes respiration is described with particular emphasis on the polysomnographic features and haemodynamic consequences of this breathing pattern. The mechanisms postulated for the genesis of CSR are reviewed. The prevalence and consequences of CSR are discussed, highlighting the clinical features and their effects on prognosis. The proposed treatments are considered, with attention being paid to the mechanisms of action, the effect on sleep, breathing, haemodynamics and the clinical utility of each therapy. Special emphasis is placed on oxygen and continuous positive airway pressure (CPAP) therapy. It is proposed that given the lack of universal acceptance of any one treatment modality, the role of new therapies that emulate the positive effects of current treatments, warrant further investigation. A review of noninvasive ventilation including a survey of its historical use, methodological considerations, physiological consequences and clinical applications has been undertaken.

Introdução: A apnéia central do sono e a apnéia obstrutiva do sono (ACS e AOS, respectivamente) são comuns em pacientes com insuficiência cardíaca com disfunção sistólica (ICC). No entanto, vários fatores que levam a instabilidade respiratória incluindo baixo débito cardíaco, congestão pulmonar e hipocapnia coexistem nestes pacientes. Pacientes com valvopatias (VAL) com alta pressão de capilar pulmonar (PCP) e com fração de ejeção (FE) de ventrículo esquerdo normal representam um modelo adequado para elucidar a gênese da apnéia do sono. Objetivos: Comparar as características dos distúrbios respiratórios do sono em pacientes com VAL e pacientes com ICC. Métodos: Pacientes com VAL com PCP > 12 mmHg e pacientes com ICC foram avaliados por, gasometria arterial, ecocardiograma e polissonografia. Resultados: Pacientes com VAL (n=17, PCP 24 ± 9 mmHg e FE 61 ± 6 %) e ICC (n=17, FE 31 ± 10 %) eram semelhantes quanto as características demográficas e gases arteriais (idade: 46 ± 10 versus 47 ± 9, sexo feminino: 11 em ambos os grupos, índice de massa corporal: 26 ± 5 vs 26 ± 6 Kg/m2, PaCO2: 34 ± 3 vs 35 ± 4 mmHg, respectivamente). Pacientes com VAL apresentaram índice de apnéia-hipopnéia (IAH) significativamente menor do que pacientes com ICC (10 ± 8 e 26 ± 25 eventos/hora, p=0,0179) e uma menor prevalência de apnéia do sono (IAH > 15 eventos/hora, 29% e 53%, p=0,0009). Dentre os pacientes com apnéia do sono, os pacientes com VAL apresentaram predominantemente AOS (60%) enquanto os pacientes com ICC apresentaram predominantemente ACS (89%, p < 0,0001). Conclusões: Pacientes com VAL e alta PCP e FE normal apresentam apnéia do sono menos grave e com excesso de eventos de origem obstrutiva quando comparados com pacientes com ICC. Congestão pulmonar e hipocapnia não explicam completamente a presença de ACS em pacientes com doenças cardíacas
Introduction: Central and obstructive sleep apnea (CSA and OSA, respectively) are common in patients with systolic congestive heart failure (ICC). However, several factors leading to respiratory instability, including low cardiac output, pulmonary congestion and hypocapnia co-exist in these patients. Patients with valvular heart disease (VAL) with high pulmonary capillary wedge pressure (PCWP) but normal resting left ventricular ejection fraction (LVEF) may provide insights into the genesis of sleep apnea. Objectives: Compare sleep disordered breathing characteristics in patients with VAL and patients with ICC. Methods: Patients with VAL and PCWP > 12 mmHg and ICC were evaluated by awake arterial blood gas analysis, echocardiogram and overnight polysomnography. Results: Patients with VAL (n=17, PCP=24 ± 9 mmHg and LVEF=61 ± 6 %) and ICC (n=17, LVEF=31 ± 10 %) were similar for demographics and blood gases (age: 46 ± 10 vs 47 ± 9, females: 11 in both groups, body mass index: 26 ± 5 Kg/m2 vs 26 ± 6, PaCO2: 34 ± 3 vs 35 ± 4 mmHg, respectively). Patients with VAL as compared to patients with ICC presented significantly lower apnea hypopnea index (10 ± 8 vs 26 ± 25 events/hour, p=0.0179), a lower prevalence of sleep apnea (apnea-hypopnea index > 15 events/hour) 29% vs 53%, p=0.0009, and among patients with sleep apnea the nature was predominantly OSA (60%) while patients with ICC had predominantly CSA (89%, p < 0.0001). Conclusion: Patients with VAL and high PCWP had a less severe sleep apnea and an excess of obstructive events when compared to patients ICC. Pulmonary congestion and hypocapnia do not completely explain CSA in patients with heart diseases

Introdução: Os distúrbios respiratórios do sono na forma de apnéia central associada à respiração de Cheyne-Stokes (RCS) e apnéia obstrutiva do sono (AOS), são comuns nos pacientes com insuficiência cardíaca (IC) e podem contribuir para morbimortalidade. A RCS é uma forma exagerada de ventilação periódica (VP) na qual apnéias centrais alternam com períodos de hiperventilação. Em contraste, a AOS resulta em um colapso completo ou parcial da via aérea superior recorrente durante o sono. Objetivo: Fizemos à hipótese que VP durante vigília prediz a RCS durante o sono em pacientes com IC. Métodos: Estudamos pacientes do ambulatório de Cardiopatia Geral, do Instituto do Coração (InCor), recrutados no período de 2001 a 2003, submetidos a avaliação clínica e ecocardiográfica. Os pacientes foram submetidos à monitoração do padrão respiratório em posição supina, com luz acesa por 10 minutos, imediatamente antes do início de registro do sono por polissonografia noturna. Na manhã seguinte, o padrão respiratório foi monitorado por 10 minutos em repouso, os pacientes permaneciam sentados, seguido por teste de exercício cardiopulmonar em bicicleta ergométrica, com medida de fração expirada de CO2 e relação ventilação/CO2 (VE/VCO2). A presença dos distúrbios respiratórios do sono foi determinada através de polissonografia (índice de apnéia-hipopnéia 15 eventos/hora), os pacientes foram divididos nos grupos sem Distúrbio Respiratório do Sono (sem DRS), RCS e AOS. Os resultados estão apresentados como média ± desvio padrão. Resultados: Foram incluídos no estudo 47 pacientes, 5 foram excluídos por falta de coordenação motora e incapacidade de realizar o teste de exercício em bicicleta. O grupo final se constituiu de 42 pacientes (67% masculino, idade = 62±9 anos, fração de ejeção ventricular esquerda = 35±6%), sendo 22 do grupo sem DRS, 11 do grupo RCS e 9 do grupo AOS. Não houve diferenças significativas nos grupos nos parâmetros antropométricos e fração de ejeção ventricular esquerda. O grupo RCS apresentou maior proporção de classe funcional III e IV (p=0,03), menor pressão parcial de dióxido de carbono em repouso (p=0,01) e maior inclinação da curva de relação da ventilação versus produção de dióxido de carbono (VE/VCO2) (p=0,03) do que os grupos sem DRS e AOS. A VP durante a vigília foi presente em 19%, 31% e 36% antes, durante o exercício e antes do sono, respectivamente. Entre os pacientes, a VP durante a vigília (independente do momento) foi presente em 91% nos pacientes com RCS e significativamente menor em 18% e 22% nos pacientes sem DRS e AOS, respectivamente (p<0,001). Ao contrário, entre os pacientes com VP, o sono se caracterizou como sem DRS, RCS e AOS em 25%, 63% e 13% (p<0,05). A sensibilidade e especificidade da VP antes do exercício (sentado) e VP antes do sono (posição supina) para prever RCS foi de 56 e 88% e 91 e 84%, respectivamente. Conclusões: A VP durante a vigília, tanto antes do exercício como antes do sono, prevê a presença da RCS. A presença da VP na vigília não está associada com a AOS. A monitoração do padrão respiratório durante a vigília é um teste simples que pode ser empregado para prever a presença da RCS em pacientes com IC
Introduction: Sleep disordered breathing in the form of central sleep apnea and Cheyne-Stokes respiration (CSR) and obstructive sleep apnea (OSA) are common among heart failure (HF) patients and can independently contribute to morbimortality. CSR is an exaggerated form of periodic breathing (PB) in which central apneas alternate with periods of hyperventilation. In contrast, OSA results from recurrent collapse of upper airway during sleep. Objective: We hypothesize that PB while awake predicts CSR during sleep in patients with HF. Methods: Patients were recruited from one outpatient heart failure clinic (Instituto do Coração, InCor) in the period 2001 until 2003. All patients were submitted respiratory monitoring, for 10 minutes while awake in supine position immediately before overnight polysomnography. In the next morning, the patients were monitored for 10 minutes while sitting in a comfortable chair at rest, followed by cardiopulmonary exercise tests (electromagnetic-braked cycle). The presence of sleep disordered breathing was determined through polysomnography (apnea-hypopnea index 15 events/hour). The patients were divided according to the respiratory pattern during sleep in no-Sleep Disordered Breathing (no-SDB), CSR and OSA. Results: Forty seven patients were included in the study, 5 were excluded because of inability to perform exercise. The final group consisted of 42 patients (67% males, age: 62±9 yr, left ventricular ejection fraction: 35±6%). There were 22 in the no-SDB group, 11 in the CSR group and 9 in the OSA group. There were no significant differences among groups regarding anthropometric measurements and left ventricular ejection fraction. The CSR group presented a significantly increased proportion of NYHA functional class III-IV (p=0.03), lower PETCO2 (p=0.01) and increased VE/VCO2 slope (p=0.03) than no-SDB and OSA groups. PB while awake was present 19%, 31% e 36% before and during exercise and before sleep, respectively. Among patients with no-SDB, CSR and OSA, PB while awake was present in 18%, 91% and 22% (p<0.001). Conversely, among patients with PB while awake, the patients were classified as no-SDB, CSR and OSA in 25%, 63% and 13% (p<0.05). PB while awake before exercise and before sleep had sensitivity and specificity to predict the presence CSR of 56 and 88 % and 91 and 84 %, respectively. Conclusions: PB while awake is tightly linked and predicts CSR during sleep, but not OSA. PB while awake can have use in a simple test for to predict the presence of CSR in patients with HF

Le cœur est au centre du système cardiorespiratoire et l’électrocardiogramme (ECG) est un des examens les plus courants pour suivre son bon fonctionnement avec l’échocardiographie. L’analyse du signal électrocardiographique est complexe de par les nombreuses pathologies cardiaques et l’émergence des nouvelles technologies de mesure a permis l’acquisition d’ECG de plus en plus long mais également bruité lors leur utilisation dans un contexte de vie courante. La taille de ces données et le bruit imposent le développement de méthodes d’analyse plus précises et plus robustes. Dans cette thèse nous proposons une méthode de restauration des ondes cardiaques en utilisant un dictionnaire de gaussiennes asymétriques. Elle permet de caractériser entièrement chaque onde (P, Q, R, S et T) à l’aide d’un faible nombre de paramètres. Cette modélisation permet également le calcul précis des différents intervalles utilisés classiquement en électrocardiographie et de classer des anomalies visibles sur les ondes puis de finalement labéliser les différents battements pour permettre une lecture accélérée des signaux longs et une aide au diagnostic pour les cardiologues. Dans la dernière partie de ce travail, ces outils d’analyse sont mis en application sur deux sujets : le premier est consacré à la création d’un simulateur d’électrocardiogramme dans le cadre du projet Hôpital Virtuel de Lorraine ; et le deuxième, sur la détection du syndrome d’apnées du sommeil via l’électrocardiogramme et plus particulièrement le dépistage de la respiration de Cheyne-Stokes, une pathologie respiratoire nocturne encore peu comprise, impactant principalement les insuffisants cardiaques. La méthode est basée sur l’extraction de signaux corrélés à la respiration issus de l’électrocardiogramme et permettent de graduer différents stades de la respiration de Cheyne-Stokes
The heart is at the center of the cardiorespiratory system and the electrocardiogram is one of the most standard medical exam to monitor it along with echocardiography. Electrocardiogram analysis is complex due to the various cardiac pathologies and the emergence of new measurement technologies allows the acquisition of longer but also noisier signals taken in a daily life context. Noise and the huge amount of processed data impose the development of more accurate and robust analytical methods. This thesis aims at developing a new modeling method of cardiac waves using a dictionary composed of skew normal distribution. It fully characterizes each wave (P, Q, R, S and T) through a small number of parameters. This modeling also permits the precise computation of the different classical intervals used in electrocardiography but also the classification of each beat to provide an accelerated reading of long signals and a diagnostic assistance. Finally, those analytical tools are used on two different subjects: the creation of an electrocardiogram simulator as part of the Hopital Virtuel de Lorraine project ; and the detection of sleep apnea syndrom on electrocardiogram signals and more particularly the Cheyne-Stokes respiration, a nocturnal respiratory pathology still not understood, primarily impacting patients with severe heart failure. The method is based on the extraction of signals correlated to respiration from the electrocardiogram signal and allows to graduate different levels of the Cheyne-Stokes respiration

Estudis recents han demostrat una elevada freqüència de trastorns respiratoris del son (TRS) en pacients amb ictus. Presentem els tres articles que formen part de la tesi doctoral: Sleep-related breathing disorders in acute lacunar stroke. J Neurol. 2009 Dec; 256(12):2036-42 L’objectiu va ser examinar la presència de TRS en pacients amb un primer infart lacunar. Es van estudiar 68 pacients amb infart lacunar i es va realitzar una poligrafia respiratòria. Un total del 69% dels pacients tenia un IAH ≥ 10, i un 25% tenia un IAH ≥ 30. Un 20,6% dels pacients tenien respiració de CS. La combinació de les variables tabaquisme o afectació topogràfica a càpsula interna o protuberància va ser significativament més freqüent en pacients amb un IAH ≥ 10 que amb un IAH < 10 (80,9% vs 57,1%; p=0,04). Per altra banda, la combinació de les variables tabaquisme i afectació de la càpsula interna o protuberància va ser més freqüent en els pacients amb un IAH ≥ 30 respecte als pacients amb un IAH < 30 (29,4% vs 3,9%; p=0,001). L’anàlisi multivariant mostrava una relació significativa i independent entre l’IAH ≥ 10 i el tabaquisme o l’afectació neurològica a la càpsula interna o a la protuberància (OR = 3.17, 95% IC 1.02-9.79; p=0,045); i entre l’IAH ≥ 20 amb l’afectació de la càpsula interna o la protuberància en fumadors (OR = 9.25, 95% IC 1.05-81.70; p=0.045). Els infarts lacunars amb afectació de la càpsula interna i la protuberància en pacients fumadors s’associen a una major incidència de TRS. Cheyne-stokes respiration in patients with first-ever lacunar stroke. Sleep Disord. 2012; 2012:257890 Aquest segon treball valora la presència de respiració de CS en pacients amb infart lacunar, determinant la seva freqüència en aquests pacients i identificant les variables associades a aquest patró de respiració en aquesta mostra. L’estudi va incloure 68 pacients ingressats per un primer infart lacunar. Es va observar respiració de CS en 14 pacients (20,6%). Els pacients amb respiració de CS en comparació amb aquells sense respiració de CS, van mostrar una mitjana de l’IAH significativament més alt (IAH 34,9, DE 21,7) vs (IAH 18,5, DE 14,4; p=0,001), així com de l’ IAC (IAC 13,1, DE 13,8) vs (IAC 1,8, DE 3,4; p=0,0001), i presentaven majors puntuacions de l’índex de Barthel i l’escala neurològica canadenca i més dies d’ingrés hospitalari. Es va poder observar una tendència a una major probabilitat de respiració de CS en els infarts lacunars amb disfunció motora possiblement per una lesió a la via piramidal. Early treatment of obstructive apnoea and stroke outcome: a randomised controlled trial. Eur Respir J. 2011 May; 37(5):1128-36. L'objectiu d’aquest assaig clínic, multicèntric, va ser avaluar l'impacte del tractament amb CPAP en pacients amb ictus isquèmic en un seguiment a 2 anys. Els pacients amb un IAH ≥ 20 van ser aleatoritzats per rebre tractament convencional de l'accident cerebrovascular i afegint el tractament amb la CPAP o el tractament convencional sense CPAP (grup control) durant la fase aguda de l'ictus. El percentatge de pacients amb millora neurològica 1 mes després de l’ictus va ser major en el grup CPAP (Rankin 90,9 vs 56,3%, p=0,01; Canadenca 88,2 vs 72,7%, p=0,05). El temps mitjà fins a l'aparició d'esdeveniments cardiovasculars va ser superior en el grup CPAP (14,9 vs 7,9 mesos; p=0.044), tot i que la supervivència lliure d'esdeveniments cardiovasculars als 24 mesos i la taxa de mortalitat cardiovascular va ser similar als dos grups. L'ús precoç de la CPAP després d’un ictus sembla accelerar la recuperació neurològica i pot retardar l'aparició d’esdeveniments cardiovasculars, malgrat no es va observar una millora en la supervivència dels pacients.
Sleep-related breathing disorders in acute lacunar stroke. J Neurol. 2009 Dec; 256(12):2036-42 The purpose was to examine the occurrence of sleep-related breathing disorders (SRBD) and variables related to SRBD in patients with acute lacunar stroke. A total of 69.1% of patients showed AHI ≥10, 44.1% AHI ≥20, and 25% AHI ≥30. Cheyne-Stokes respiration (CSR) was present in 20.6% of patients. In the multivariate analysis, smoking or capsular or pontine topographies were associated with AHI ≥10 (OR=3.17, 95%(CI) 1.02–9.79; P=0.045). Lacunes in the internal capsule or the pons in smokers were associated with AHI ≥20 (OR=9.25, 95%(CI) 1.05–81.70; P=0.045). Smoker patients with capsular or pontine acute lacunar stroke should be screened for SRDB. Cheyne-stokes respiration in patients with first-ever lacunar stroke. Sleep Disord. 2012; 2012:257890 The aim of this single-center prospective study was to assess the presence CSR and CSR-related variables in 68 consecutive patients with radiologically proven first-ever lacunar stroke. CSR was diagnosed in 14 patients (20.6%). Patients with CSR as compared with those without CSR showed a significantly higher scores of the Barthel index and the Canadian Neurological scale as a measure of stroke severity, and longer hospital stay. The presence of CSR was associated with a trend towards a higher functional stroke severity and worse prognosis. Early treatment of obstructive apnoea and stroke outcome: a randomised controlled trial. Eur Respir J. 2011 May; 37(5):1128-36. The aim of the present study was to assess the impact of nCPAP in ischaemic stroke patients followed for 2 yrs. Stroke patients with an AHI ≥ 20 events/h were randomised to early nCPAP (n571; 3–6 days after stroke onset) or conventional treatment (n569). The percentage of patients with neurological improvement 1 month after stroke was significantly higher in the nCPAP group. The mean time until the appearance of cardiovascular events was longer in the nCPAP group (14.9 versus 7.9 months; p=0.044), although cardiovascular event-free survival after 24 months was similar in both groups. Early use of nCPAP seems to accelerate neurological recovery and to delay the appearance of cardiovascular events, although an improvement in patients survival was not shown.

Cette thèse est consacrée à la modélisation de la ventilation mécanique chez l'humain et à l'analyse numérique des systèmes en découlant. Des simulations directes d'écoulement d'air dans l'ensemble des voies aériennes étant impossibles (maillages indisponibles et géométrie trop complexe), il est nécessaire de considérer un domaine d'intérêt réduit, qui implique de travailler dans une géométrie tronquée, comportant des frontières artificielles ou encore de considérer des modèles réduits simples mais représentatifs. Si on cherche à effectuer des simulations numériques 3D où l'écoulement du fluide est décrit par les équations de Navier-Stokes, différentes problématiques sont soulevées :- Si on considère que la ventilation est la conséquence de différences de pression, les conditions aux limites associées sont des conditions de type Neumann. Cela aboutit à des questions théoriques en terme d'existence et d'unicité de solution et à des questions numériques en terme de choix de schémas et de méthodes adaptées.- Lorsque l'on travaille dans un domaine tronqué, il peut être nécessaire de prendre en compte les phénomènes non décrits grâce à des modèles réduits appropriés. Ici nous considérons des modèles 0D. Ces couplages 3D/0D sont à l'origine d'instabilités numériques qu'on étudie mathématiquement et numériquement dans ce manuscrit. Par ailleurs, lorsqu'on s'intéresse à des régimes de respiration forcée, les modèles usuels linéaires sont invalidés par les expériences. Afin d'observer les différences entre les résultats expérimentaux et numériques, il est nécessaire de prendre en compte plusieurs types de non linéarités, comme la déformation du domaine ou les phénomènes de type Bernoulli. Une approche par modèles réduits est adoptée dans ce travail.Pour finir, on a cherché à valider les modèles obtenus en comparant des résultats numériques et des résultats expérimentaux dans le cadre d'un travail interdisciplinaire.Parvenir à modéliser et simuler ces écoulements permet de mieux comprendre les phénomènes et paramètres qui entrent en jeu lors de pathologies (asthme, emphysème...). Un des objectifs à moyen terme est d'étudier l'influence du mélange hélium-oxygène sur le dépôt d'aérosol, toujours dans le cadre du travail interdisciplinaire. A plus long terme, l'application de ces modèles à des situations pathologiques pourrait permettre de construire des outils d'aide à la décision dans le domaine médical (compréhension de la pathologie, optimisation de thérapie...)
In this thesis, we study the modelling of the human mecanical ventilation and the numerical analysis of linked systems. Direct simulations of air flow in the whole airways are impossible (complex geometry, unavailable meshes). Then a reduced area of interest can be considered, working with reduced geometries and artificial boundaries. One can also use reduced models, simple but realistic. If one try to make 3D numerical simulations where the fluid flow is described by the Navier-Stokes equations, various issues are raised:- If we consider that ventilation is the result of pressure drops, the associated boundary conditions are Neumann conditions. It leads to theoretical questions in terms of existence and uniqueness of solution and numerical issues in terms of scheme choice and appropriate numerical methods.- When working in a truncated domain, it may be necessary to take into account non-described phenomena with appropriate models. Here we consider 0D models. These 3D/0D couplings imply numerical instabilities that we mathematically and numerically study in this thesis.Furthermore, when we focus on forced breathing, linear usual models are invalidated by experiments. In order to observe the differences between the experimental and numerical results, it is necessary to take into account several types of non-linearities, such as deformation of the domain or the Bernoulli phenomenon. A reduced model approach is adopted in this work. Finally, we sought to validate the obtained models by comparing numerical and experimental results in the context of interdisciplinary work.Achieving model and simulate these flows allow to better understand phenomena and parameters that come into play in diseases (asthma, emphysema ...). A medium-term objective is to study the influence of helium-oxygen mixture in the aerosol deposition. In the longer term, the application of these models to pathological situations could afford to build decision support tools in the medical field (understanding of pathology, therapy optimization ...)

Central sleep apnoea and Cheyne-Stokes respiration are common forms of sleep-disordered breathing, particularly in patients with co-morbidities such as cardiac and renal disease which, however, often do not require specific treatment. Physicians may encounter such patients in their outpatient clinics or as ward referrals in hospital. A typical case is presented to aid the approach to such patients, including how to make an accurate diagnosis, which of the various treatment modalities to use, and what to do if a treatment fails. The evidence for the different interventions is explored, including oxygen, modes of non-invasive positive airway pressure, and drug treatments, with particular attention to groundbreaking studies.

This chapter describes positive airway pressure (PAP) therapy for sleep disordered breathing. Continuous PAP (CPAP) acts as a mechanical splint on the upper airway and is the treatment of choice for moderate to severe obstructive sleep apnea (OSA). Autotitrating CPAP may be used when the pressure demand for stabilizing the upper airway is quite variable. In other cases, fixed CPAP is sufficient. There is robust evidence that CPAP reduces the symptomatic burden and risk of cardiovascular comorbidity in patients with moderate to severe OSA. Bilevel PAP is indicated for treatment of respiratory diseases characterized by chronic alveolar hypoventilation, which typically deteriorates during sleep. Adaptive servo-ventilation is a mode of bilevel PAP used to treat Cheyne–Stokes respiration with central sleep apnea . It is crucial that caregivers help patients get used to and be compliant with PAP therapy. Education, support, and resolution of adverse effects are mandatory for therapeutic success.
