Forced expiratory volume before and after isoprenaline.
Improvement in the results of tests of ventilatory function in response to a bronchodilator drug, given by inhalation or by injection, is now widely used to indicate the presence of reversible " bronchospasm" (Rossier, 1949; Gilson and Hugh-Jones, 1955; Kennedy and Thursby-Pelham, 1956). Frequent repetition of some of these tests in a small series of patients has revealed an interesting relatio...
متن کاملVariability of relaxed expiratory volume and forced inspiratory volume.
Measurements of relaxed expiratory volume in one second (REV1.0) and forced inspiratory volume in one second (FIV1.0) were made on 50 subjects on two occasions to know the variability of these procedures in the individual subject. The mean coefficients of variation for REV1.0 and FIV1.0 were 6740' and 892%, respectively. The 95% confidence limit of difference between highest readings obtained o...
متن کاملPrecipitous fall of the forced expiratory volume.
Patients attending hospital on account of chronic airways obstruction usually present with breathlessness. Most, at this stage, are found to have a severe reduction of the forced expiratory volume (F.E.V.), but little is known about the nature of the deterioration in ventilatory function in earlier phases of the illness. Two patients are described to show how precipitous this deterioration may ...
متن کاملEffort and the forced expiratory volume in one second (FEV).
1. The relationship between volumes expired and the maximum intrathoracic pressures developed within the first second of expiration was examined in a group of healthy subjects and patients with airways obstruction who exhaled with varying degrees of effort. 2. The body plethysmographic method was used to ensure that expirations started from total lung capacity. 3. Three different types of volum...
متن کاملPhysical activity and its effect on forced expiratory volume.
OBJECTIVE To assess and compare changes in pulmonary functions before and after exercise in young healthy adults. METHODS The case-control study was carried out from January to March 2010 on 292 medical students aged 18-24 years at Bahria University Medical and Dental College, Karachi. Baseline values for forced expiratory volume (FEV1) and forced vital capacity (FVC) were measured with a dig...
