A brief discontinuation (1 week) of long-term ventilation may be necessary in patients who are not totally ventilator-dependent in cases of technical problems, intolerable nasal irritation, upper airway congestion, or travel. We examined the incidenc

Objective To investigate the effects of positive end-expiratory pressure (PEEP) on end-expiratory lung volume (EELV) and mean oscillated flow rate ( V ˙ osc ) during high-frequency chest compression (HFCC) in normal subjects and patients with severe

The oxygen cost of augmented ventilation is increased in patients with chronic obstructive pulmonary disease, either at rest or during exercise. Thus, if excessive demands are placed on the respiratory muscles during exercise in these patients, we po

Four examiners performed standardized physical examinations on patients who had recently had tests of pulmonary function. Four physical signs were studied: intensity of breath sounds during brisk deep inspiration, palpable tensing of scalene muscles

Shortness of breath is a chief complaint of many individuals with cardiopulmonary diseases. Exercise testing is often used to help differentiate cardiac from pulmonary involvement. In assessing pulmonary dysfunction during exercise it is essential to

In seven patients with upper airway obstruction caused by tracheal or vocal cord lesions, pulmonary function tests revealed normal distribution of ventilation and a moderate to marked elevation in airway resistance unresponsive to bronchodilators. Su

Nine patients with moderate to severe chronic obstructive lung disease were grouped according to results of pulmonary function testing. After a short period of 100 percent oxygen breathing, it took on the average 20 minutes (range--18 to 24 minutes)

Hypoxemia occurs during routine hemodialysis and may contribute to morbidity, but its cause is not well understood. We reasoned that patients with COPD would be more vulnerable to abnormalities in gas exchange with dialysis. Thus, to investigate the

We evaluated application of a Pth device for testing inspiratory muscle endurance among patients with severe but stable COPD. Endurance time in five patients was reproducible. Magnitude of variability was +/- 1.26 minutes with a range of +/- 0.19 to

We studied the frequency of cardiac arrhythmias during routine tests of pulmonary function by using continuous electrocardiographic recording and a computerized method to quantitate arrhythmias. A total of 150 patients with chronic obstruction of air
