This study hypothesizes that: peak supramaximal airflow during cough reflects expiratory muscle effort, and that expiratory muscle function during cough might be assessed from the airflow signal alone. We monitored airflow and oesophageal pressure (P

The aim of this study was to assess the utility of clinical assessment of respiratory muscle weakness in MS.We studied 40 MS patients who performed pulmonary function tests using standard procedures and measures of respiratory muscle strength. Descri

The purpose of this study was to evaluate three bedside methods for measuring respiratory system resistance to airflow (Rrs). To this end, we studied 19 intubated patients, 6 of whom had diseases characterized predominantly by acute airway obstructio

Ventilation (liters of air per minute) increases during an acute attack of asthma. Hypocapnia is the rule, although eucapnia may occur. This suggests both that respiratory center output is increased and that acidemia is not the major stimulus to augm

Volume-pressure diagrams during inflation with air and saline were made with the lungs of 6 control dogs and 24 dogs with acute alveolar injury induced by subcutaneous injection of 6 mg of N-nitroso-N-methylurethane per kg of body weight 3 to 14 days

The reliability and validity of an Index of Pulmonary Dysfunction in Multiple Sclerosis (Index) comprised of four readily assessed clinical signs was studied. Forty patients with MS performed pulmonary function testing and underwent clinical evaluati

To evaluate the bioavailability of a new theophylline preparation suitable for once-a-day (od) oral administration, we performed a nonrandomized crossover study in which the absorption of the OD and a standard twice-a-day (bid) preparation were compa

To evaluate independently the effects of an inspiratory stimulus (a mouthpiece) and a ventilatory depressant (oxygen) on minute ventilation (VE) in asthma, we measured VE with magnetometers in 18 asthmatic subjects. When room air was inspired from a
