Abstract A novel technique for achieving plethysmography measurements utilizing noncontact laser displacement sensors is described. This method may have utility in measuring respiratory and pulmonary function similar to that of respiratory inductive plethysmography. The authors describe the apparatus and method and provide results of a validation study comparing respiratory excursion data obtained by (1) the laser sensor technique, (2) standard respiratory inductive plethysmography (RIP), and (3) lung volume measurements determined by pressure variations in a control volume. Six healthy volunteers (five female, one male, ages ranging from 19 to 23 years) were measured for tidal breathing excursions simultaneously via all three measurement techniques. Results: Excellent correlation between the techniques was shown. Pairwise comparisons among all three measurement techniques across all subjects showed intraclass correlation coefficients of 0.995 in each case. These results indicate the laser plethysmograph (LP) system provides results that are, at a minimum, equivalent to those of the RIP at the two sites commonly measured by RIP. Use of the LP system has the potential to provide much more extensive and precise measurements of chest wall function and the respiratory musculature.

In infants under the age of 6 mo respiratory inductive plethysmograph (RIP)-calculated tidal volumes (VT) were compared with simultaneously measured volumes using a pneumotachograph (PNT) to 1) assess whether using multiple points (MP) along the inspiratory profile of a breath is superior to using only VT when calculating volume-motion (VM) coefficients, 2) verify the assumption of independent contributions of the abdomen and rib cage to VT, which was accomplished by extending the normal RIP model to include a term representing interaction between these two compartments, and 3) investigate whether VM coefficients are sleep-state dependent. Neither use of multiple points nor inclusion of the interacting term improved the performance of the RIP over that observed using a simple two-compartment model with VT measurements. However, VM coefficients obtained during quiet sleep (QS) were not reliable when used during rapid-eye-movement (REM) sleep, suggesting that coefficients obtained during one sleep state may not be applicable to another state where there is a substantial change in the relative abdominal/rib cage contributions to VT.

Positive airway pressure (Paw) during high-frequency oscillatory ventilation (HFOV) increases lung volume and can lead to lung overdistention with potentially serious adverse effects. To date, no method is available to monitor changes in lung volume (ΔVl) in HFOV-treated infants to avoid overdistention. In five newborn piglets (6–15 days old, 2.2–4.2 kg), we investigated the use of direct current-coupled respiratory inductive plethysmography (RIP) for this purpose by evaluating it against whole body plethysmography. Animals were instrumented, fitted with RIP bands, paralyzed, sedated, and placed in the plethysmograph. RIP and plethysmography were simultaneously calibrated, and HFOV was instituted at varying Paw settings before (6–14 cmH2O) and after (10–24 cmH2O) repeated warm saline lung lavage to induce experimental surfactant deficiency. Estimates of ΔVl from both methods were in good agreement, both transiently and in the steady state. Maximal changes in lung volume (ΔVl max) from all piglets were highly correlated with ΔVl measured by RIP (in ml) = 1.01 × changes measured by whole body plethysmography − 0.35; r 2 = 0.95. Accuracy of RIP was unchanged after lavage. Effective respiratory system compliance (Ceff) decreased after lavage, yet it exhibited similar sigmoidal dependence on ΔVl max pre- and postlavage. A decrease in Ceff (relative to the previous Paw setting) as ΔVl max was methodically increased from low to high Paw provided a quantitative method for detecting lung overdistention. We conclude that RIP offers a noninvasive and clinically applicable method for accurately estimating lung recruitment during HFOV. Consequently, RIP allows the detection of lung overdistention and selection of optimal HFOV from derived Ceff data.

We describe a single-posture method for deriving the proportionality constant (K) between rib cage (RC) and abdominal (AB) amplifiers of the respiratory inductive plethysmograph (RIP). Qualitative diagnostic calibration (QDC) is based on equations of the isovolume maneuver calibration (ISOCAL) and is carried out during a 5-min period of natural breathing without using mouthpiece or mask. In this situation, K approximates the ratio of standard deviations (SD) of the uncalibrated changes of AB-to-RC volume deflections. Validity of calibration was evaluated by 1) analyzing RIP waveforms during an isovolume maneuver and 2) comparing changes of tidal volume (VT) amplitude and functional residual capacity (FRC) level measured by spirometry (SP) with RIP values. Comparisons of VT(RIP) to VT(SP) were also obtained in a variety of postures during natural (uninstructed) preferential RC and AB breathing and with voluntary changes of VT amplitude and FRC level. VT(RIP)-to-VT(SP) comparisons were equal to or closer than published reports for single posture, ISOCAL, multiple- and linear-regression procedures. QDC of RIP in supine posture with comparisons to SP in that posture and others showed better accuracy in horizontal than upright postures.

Respiratory inductance plethysmography (RIP) has been widely used to measure ventilation during sleep, but its accuracy in this role has not been adequately tested. We have thus examined the accuracy of the RIP by comparing tidal volume measured with RIP with that measured by a pneumotachograph in eight unrestrained normal subjects during sleep. We have also studied the effect of posture on the accuracy of the RIP. In all sleep stages the correlation between RIP tidal volume measurements and expired volume showed relatively poor correlations (mean r = 0.49–0.60), and the bias of the measurements varied widely. Changes in posture altered the correlations between the two measurements, with no systematic differences between positions. When the subjects resumed a position, the 95% confidence intervals of tidal volume measurement did not overlap the original confidence limits in that posture on 13 of 25 occasions. This study shows that the RIP does not accurately measure tidal volume during sleep in unrestrained subjects and should only be used for semiquantitative assessment of ventilation during sleep.

In this study, we have developed a “double-empirical mode decomposition algorithm” to estimate cardiac stroke volume from respiratory inductive plethysmography (RIP) signals. The algorithm consists of first an ensemble empirical mode decomposition (EEMD) to extract the cardiorespiratory components. Then, it is followed by an empirical mode decomposition (EMD) to extract only the cardiac components. This double approach permits (a) solving problems of mixing between cardiac and respiratory components (mode and scale mixing), (b) cardiogenic oscillations extraction in the respiratory inductive plethysmography signal, and (c) subsequent estimation of stroke volume. The algorithm is applied to simulated and real RIP signals. The simulated signals are generated by a cardiorespiratory model previously published by the authors. The real signals are measured via a developed inductive vest. In the real case, the values of estimated stroke volumes are compared to the values obtained by thoracocardiographic filter-based method. In the simulated case, the values are compared to the simulated cardiac activity. The results of comparison through Bland and Altman indicate an error lying in the range ±10%. In contrast to thoracocardiography, the proposed method consists of a promising tool for continuous noninvasive adaptive cardiac monitoring that does not need adjusting parameters or cut-off based on ECG. Also, in comparison to echocardiography and impedance-based methods, it does not necessitate the presence of an expert and is not too sensitive to current penetration.

Indirect methods of measuring ventilation, such as the respiratory inductive plethysmograph (RIP), operate on the assumption that the respiratory system possesses two degrees of freedom of motion: the rib cage and abdomen. Accurate measurements have been obtained in many patients with pulmonary disease who possess additional degrees of freedom. Since calibration and validation of the RIP was carried out during quiet breathing in these patients, the amount of asynchronous or paradoxic breathing was presumably similar during the calibration and validation runs. Conversely, accuracy might be lost if following the initial calibration procedure the magnitude of chest wall distortion increased during subsequent validation runs. We calibrated the RIP during quiet breathing and examined its accuracy while subsequently breathing against resistive loads that required the generation of 20–80% of the subject's maximum inspiratory mouth pressure (Pmmax). We compared the relative accuracy of three commonly employed calibration methods: isovolume technique, least-squares technique, and single position loop-area technique. Up to 60% of Pmmax, 89% of the RIP values with the least-squares technique were within +/- 10% of simultaneous spirometric (SP) measurements and 100% were within +/- 20% of SP, compared with 63 and 91%, respectively, for the loop-area technique and 19 and 54%, respectively, for the isovolume technique. At 70 and 80% of Pmmax accuracy deteriorated. Accuracy of respiratory timing was judged in terms of fractional inspiratory time (TI/TT).(ABSTRACT TRUNCATED AT 250 WORDS)

The present study was undertaken to evaluate whether the respiratory inductive plethysmograph (RIP) 1) reflects changes of cross-sectional area enclosed by its transducer band in the presence of deformations of shape or whether it 2) has a stable base line. Testing of RIP was carried out with a device incorporating a thermally compensated oscillator and digital demodulatory circuitry. This system, introduced to commerce in 1983, superceded the nonthermal compensated oscillatory and analog demodulator circuitry first used in 1977. Testing the effects of changing cross-sectional area was accomplished by stretching a standard RIP transducer band around wooden dowels placed in holes on a peg board grid to form 23 curved and 5 rectangular shapes. The output voltage from RIP was linear for both the curved and rectangular shapes for changes of cross-sectional area within a physiological range. However, the regression line of voltage vs. cross-sectional area for the rectangular shapes was parallel and slightly displaced from the regression line for the curved shapes due to mutual coupling of inductance in the corners. Base-line drift from a RIP transducer band stretched to enclose an elliptical shape was less than 2.5 mV over a 12-h observation period. Current RIP technology accurately reflects changes of cross-sectional area of physiological shapes and has a stable base line.

Respiratory rate (RR) is a valuable early marker of illness in vulnerable infants, but current monitoring methods are unsuitable for sustained home use. We have demonstrated accurate measurement of RR from brief recordings of pulse oximeter plethysmogram (pleth) trace in full-term neonates in hospital. This study assessed the feasibility of this method in preterm infants during overnight recordings in the home. We collected simultaneous overnight SpO2, pleth and respiratory inductive plethysmography (RIP) on 24 preterm infants in the home. RR from pleth analysis was compared with RR from RIP bands; pleth quality was assessed by the presence of visible artefact. Median (range) RR from RIP and pleth were not significantly different at 42 (25–65) and 42 (25–64) breaths/min. Median (range) % of epochs rejected due to artefact was 20 (8–75) for pleth and 10 (3–53) for RIP. Our results suggest that home RR monitoring by pulse oximeter pleth signal is accurate and feasible.

The objective of the present study is to extract new information from complex signals generated by Respiratory Inductive Plethysmography (RIP). This indirect cardio-respiratory (CR) measure is a well-known wearable solution. The authors applied time-scale analysis to estimate cardiac activity from thoracic volume variations, witnesses of CR interactions. Calibrated RIP signals gathered from 4 healthy volunteers in resting conditions are processed by Ensemble Empirical Mode Decomposition to extract cardiac volume signals and estimate stroke volumes. Averaged values of these stroke volumes (SVRIP) are compared with averaged values of stroke volumes determined simultaneously by electrical impedance cardiography (SVICG). There is a satisfactory correlation between SVRIP and SVICG (r=0.76, p<0.001) and the limits of agreement between the 2 types of measurements (±23%) satisfies the required criterion (±30%). The observed under-estimation (-58%) is argued. This validates the use of RIP for following stroke volume variations and suggests that one simple transducer can provide a quantitative exploration of both ventilatory and cardiac volumes.

L'objectif principal qui guide les développements en traitement du signal de cette thèse est la mise au point d'un outil qui s'inscrit dans une démarche de physiologie intégrative où, à chaque échelle, le modèle des signaux peut être différent On cherche ici à restreindre le jeu d'hypothèses a priori à un ensemble de règles physiologiques qui régissent les interactions entre functions physiologiques en l'absence d'hypothèses fonnelles et: mathématiques sur les signaux. Nous avons appliqué cette démarche au problème de la détection des ondes cardiaques et: de l' estimation cycle à cycle du volume d'éjection dans le signal RIP (Respiratoty Inductive Plethysmography). L'approche par décomposition empirique se prête particulièrement à notre logique. Nous proposons ici la première version d'un algorithme basé sur une double décomposition empirique du signal RIP. La méthode choisie et: les outils correspondants ont été testés sur deux types de données, d'une part des signaux simulés, d'autre part des signaux enregistrés sur volontaires sains. Notre objectif est donc aussi de mettre au point un modèle cardiorespiratoire pouvant servir d'outil de simulation des signaux ventilatoires, cardiaques et: de RIP avec la simulation de l'effet de chaque système sur l'autre. Les résultats montrent que la méthode proposée est adaptée à l'analyse du signal RIP et: à l' estimation du volume d'éjection
The main objective that guides the signal processing approaches ofthis thesis is the development of a tool that oould be part of an integrative physiology approach where, at each scale, the model of signais may be different We seek here the restriction of asstnnptions a priori to a set: of rules goveming the physiological interactions between physiological functions in the absence of fannal and mathematical assumptions. We applied this approach to the problem of cardiac waves detection and estimation of cycle-to-cycle stroke volume in the RIP signal (Respiratory Inductive Plethysmography). The empirical decomposition approach seems to be particularly adapted to our logic. We propose here the first version of an algorithm based on RIP double decomposition. The method and its COITeSpül1ding tools have been tested on two types of data, simulated signais and real signais recorded at healthy volunteers. Our aim is also therefore to develop a cardio-respiratory model that can serve as a tool for ventilatory, cardiac and RIP signals simulation along with the simulation of the effect of each system on the other. The results show that the proposed method is suitable for RIP signal analysis and for stroke volume estimation

Nas últimas décadas, considerável atenção foi direcionada para os dispositivos de mensuração não invasiva da configuração e coordenação toracoabdominal. Dentre os dispositivos mais empregados, destaca-se aquele que emprega a Pletismografia Respiratória por Indutância (PRI) que, apesar de ser considerado um dispositivo de avaliação reprodutível e acurado, apresenta divergências acerca do método de calibração para estimativa da participação dos compartimentos torácico e abdominal, principalmente quando utilizada em diferentes posturas corporais. O padrão-ouro da calibração da PRI é o método de calibração por isovolume (ISOCAL). Entretanto, a grande maioria dos estudos emprega somente a calibração qualitativa diagnóstica (QDC) devido ao fato desta não necessitar manobras respiratórias específicas. Em vista disso, o objetivo deste estudo foi comparar os dois métodos de calibração da PRI, em 3 diferentes posturas (decúbito dorsal, sedestação e ortostatismo). Foram avaliados 28 indivíduos saudáveis (18 mulheres/10 homens), com idade de 25,4±3,9 anos (média±DP). Todos os indivíduos foram submetidos aos dois métodos de calibração (ISOCAL e QDC) e avaliados nas 03 posturas. Foi verificado que os valores da constante de proporcionalidade dos sinais elétricos dos compartimentos (K) foram distintos em ambos os métodos de calibração nas 3 posturas avaliadas. Os valores de K avaliados com a calibração ISOCAL e QDC foram, respectivamente, 1,6±0,5 vs. 2,0±1,2 em decúbito dorsal, 2,5±0,8 vs. 0,6±0,3 em sedestação, e 2,0±0,8 vs. 0,6±0,3 em ortostatismo (p<0,05 para todas as comparações). Os nossos resultados sugerem que a QDC não deve ser considerada um método acurado para a calibração da PRI. Além disso, os valores da constante K do ISOCAL mostram ainda que a calibração do equipamento deve ocorrer para cada postura avaliada
In recent decades, considerable attention has been directed to devices for noninvasive measurement of thoracoabdominal configuration and coordination. Among the most commonly applied devices, there is one that employs the respiratory inductive plethysmography (PRI), which, despite being considered a device for reproducible and accurate assessment, shows variations on the calibration method to estimate the contribution of the thoracic and abdominal compartments especially when applied in different body postures. The gold standard in the calibration of PRI is the method of isovolume calibration (ISOCAL). However, most studies employ only the qualitative diagnostic calibration (QDC) due to the fact that this does not require specific respiratory maneuvers. This study aims to compare the two methods of calibration of the PRI in three different postures (supine, standing, and seated). A total of 28 healthy subjects (18 men mulheres/10), aged 25.4 ± 3.9 years (mean ± SD). All subjects underwent both methods of calibration (QDC and ISOCAL) and assessed at the 03 postures. It was found that the values of the constant of proportionality of the electrical signals of compartments (K) were different in both calibration methods evaluated in three postures. The values of K evaluated with calibration ISOCAL and QDC were respectively 1.6 ± 0.5 vs. 2.0 ± 1.2 supine position, 2.5 ± 0.8 vs. 0.6 ± 0.3 in seated position, and 2.0 ± 0.8 vs. 0.6 ± 0.3 in standing position (p <0.05 for all comparisons). Our results suggest that the QDC should not be considered an accurate method for calibration of the PRI. Moreover, the values of constant K ISOCAL also show that the calibration of equipment should occur for each position evaluated

La méthode de référence pour l’évaluation de la capacité d’exercice est l’Exploration Fonctionnelle d’eXercice (EFX). En pratique, pour des problèmes de coût, de matériel et d’expertise médicale, l’EFX n’est pas réalisée chez tous les sujets dont la capacité d’exercice mérite d’être explorée. Le test de marche de 6 minutes (6MWT) ne présente pas ces inconvénients mais ne donne pas d’informations sur les adaptations physiologiques au cours de cet exercice. L’objectif de ce travail de thèse était de concevoir une méthode non invasive de monitorage des adaptations ventilatoires et locomotrices. L’accent a été porté sur le respect du caractère spontané de ces adaptations. La pléthysmographie respiratoire d’inductance (RIP) et l’accélérométrie ont été choisies pour l’évaluation de ces adaptations. Les performances de ces nouvelles méthodes de monitorage sont acceptables pour ces deux dimensions. La confrontation de notre méthode RIP au pneumotachographe, outil de référence, objective des coefficients de corrélations compris entre 0,81 et 0,96 pour le volume courant(Vt), les temps inspiratoires (Ti) et expiratoires (Te). De même, la confrontation de notre méthode accélérométrique avec le contrôle vidéographique montre des coefficients de corrélations de 0,99 pour les paramètres locomoteurs : cadence, longueur moyenne du pas et détermination automatique des distances parcourues (6MWD). La comparaison des profils ventilatoires et locomoteurs entre contrôles et sujets obèses révèle qu’une discrimination est possible (p<0,01 pour Vt, Ti, Te et p<0 ,001 pour cadence, longueur moyenne de pas et 6MWD). Ainsi, même une population sans pathologie respiratoire comme la population obèse sans comorbidités, choisie comme modèle d’étude dans ce travail, peut être discriminée par notre méthode de monitorage. Ces résultats sont encourageants au regard de l’amélioration de la prise en charge des sujets obèses et laissent entrevoir des perspectives tant au niveau technologique qu’à un niveau clinique plus large pour, par exemple, les sujets atteints de pathologies respiratoires susceptibles de limiter leur capacité d’effort
The reference method for assessment of exercise capacity is the cardio-pulmonary exercise testing (CPET). Nevertheless, CPET is expensive, time consuming, requires specifics skills and is not used for all subjects needing exercise capacity assessment. The 6 minute walk test (6MWT) is free of these disadvantages but does not give basic information about physiological adaptation induced by walking. The aim of this study was to design a non-invasive method for ventilatory and locomotor monitoring. Respect of the spontaneous aspects of these adaptations was considered. Respiratory inductive plethysmography (RIP) was considered for ventilatory evaluation whereas locomotor adaptation was assessed with a tri-axial accelerometer. These new methods provided acceptable results for ventilatory and locomotor dimensions. Confronting our new RIP method with a pneumotachograph as a reference device, we found correlation coefficients from. 0.81 to 0.96 for determination of tidal volume (Vt), inspiratory (Ti) and expiratory time (Te). Confronting our accelerometric method with video recordings as control, we found significant correlation coefficients (r=0.99 and p< 0.001) for determination of cadence, mean step length and automatic distance covered (6MWD) during the 6MWT. Comparisons of ventilatory and locomotor pattern of control and obese without comorbidities showed that discriminating their pattern was possible (p<0.01 for Vt, Ti, Te and p<0.001 for cadence, mean step length and 6MWD). These results imply that even a population without respiratory disorders as the obese population considered in this study, can be discriminated with our monitoring method. It can be concluded that this method is promising for improvement of care to obese subjects and raises technological and clinical perspectives for subjects with respiratory disorders
