Abstract:

This study developed a novel chair-side tongue pressure (TP) measuring instrument with a disposable positioning mouthpiece controlled using a smartphone application (APP), denoted as the TP wireless application (TPWA). The mouthpiece was designed with a palate-shaped air balloon containing a tongue contact bump and a plastic bite positioning tube. Fatigue load testing was performed to evaluate mouthpiece durability by applying 700 displacement cycles (50 times a day for one week during training, with twice the safety factor) on the air balloon. The main component used in developing this instru

Abstract:

Breathing pattern and steady-state CO2 ventilatory response during mouth breathing were compared with those during nose breathing in nine healthy adults. In addition, the effect of warming and humidification of the inspired air on the ventilatory response was observed during breathing through a mouthpiece. We found the following. 1) Dead space and airway resistance were significantly greater during nose than during mouth breathing. 2) The slope of CO2 ventilatory responses did not differ appreciably during the two types of breathing, but CO2 occlusion pressure response was significantly enhanc

Abstract:

To investigate whether it is possible to simplify the methodology of measuring airway area by acoustic reflections, we measured upper airway area in 10 healthy subjects during tidal breathing according to seven different protocols. Three protocols employed custom-made bulky mouthpiece with or without nose-clips, two protocols used a scuba-diving mouthpiece and cotton balls placed in the nostrils instead of noseclips, and two protocols employed neck flexion and extension. We found no significant difference in average pharyngeal, glottic, and tracheal areas for any of the protocols except for ne

Abstract:

Bernard Shaw (1856-1950) is one of the world famous playwrights, is a household wordsmith for his good humor and satire. In his masterpiece Mrs. Warren's Profession, Shaw depicts a literary figure Vivie who embodies new women's yearning for their independence and aspirations of self-values. This paper analyzes Vivie's image through approaches of narrative theory. By using narrative voice reflected in the scene, involvement of implied author in portrayal description, application of feminism in narratology, and dualistic construction in subtext, readers can have a more profound understanding of

In the preceding companion paper (L. S. G. E. Howard and P.A. Robbins, J. Appl. Physiol. 78: 1092–1097, 1995), we showed that ventilation rises during 8 h of isocapnic hypoxia. In the present study we report the changes that occur in the ventilatory response to acute hypoxia (AHVR) over 8 h of both isocapnic and poikilocapnic hypoxia. Ten subjects completed the study. Each was seated inside a chamber in which the inspired gas could be controlled so as to maintain the desired end-tidal gases (sampled via nasal catheter) constant.

Abstract:

This article discusses the augmentation of acoustic musical instruments, with a focus on trumpet augmentation. Augmented instruments are acoustic instruments onto which sensors have been mounted in order to provide extra sonic control variables. Trumpets make ideal candidates for augmentation because they have spare physical space on which to mount electronics and spare performer “bandwidth” with which to interact with the augmentations. In this article, underlying concepts of augmented instrument design are discussed along with a review and discussion of twelve existing augmented trumpets and

Abstract:

Briefly occluding the airway during inspiration produces a short-latency reflex inhibition in human inspiratory muscles. This occlusion reflex seems specific to respiratory muscles; however, it is not known whether the reflex inhibition has a uniform effect across a motoneuron pool when a muscle is recruited concurrently for breathing and posture. In this study, participants were seated and breathed through a mouthpiece that occluded inspiratory airflow for 250 ms at a volume threshold of 0.2 liters. The reflex response was measured in the scalene and sternocleidomastoid muscles during 1) a co

Abstract:

Air hunger is an unpleasant urge to breathe and a distressing respiratory symptom of cardiopulmonary patients. An increase in tidal volume relieves air hunger, possibly by increasing pulmonary stretch receptor cycle amplitude. The purpose of this study was to determine whether increasing end-expiratory volume (EEV) also relieves air hunger. Six healthy volunteers (3 women, 31 ± 4 yr old) were mechanically ventilated via a mouthpiece (12 breaths/min, constant end-tidal Pco2) at high minute ventilation (V̇e; 12 ± 2 l/min, control) and low V̇e (6 ± 1 l/min, air hunger).
