Hypoxic ventilatory drive in normal man.
A technique is described which permits the inscription of the ventilatory response to isocapnic hypoxia in man as a continuous curve relating alveolar oxygen tension and minute ventilation. The adjustment of ventilation to changes in alveolar oxygen tension is complete in 18-23 sec and this is sufficiently rapid to justify the use of a non-steady-state method. Changes in alveolar carbon dioxide...
متن کاملOverview of Pathophysiologic Mechanisms in Chronic Ventilatory Insufficiency Direct Consequences of Respiratory Muscle Weakness
the ventilatory pump upon which the act of breathing depends. In many neuromuscular disorders, muscle weakness involves the respiratory muscles to an equal or even greater extent than other skeletal muscles. The degree of limb muscle weakness cannot be used as a reliable guide to the presence of respiratory muscle impairment since the correlation between the two may be quite poor.1,2 Respirator...
متن کاملBreathing pattern, ventilatory drive and respiratory muscle strength in patients with chronic heart failure.
The purpose of this study was to evaluate whether chronic heart failure (CHF) may induce changes in breathing pattern and ventilatory neural drive. We studied 45 male inpatients with CHF, (25 patients in NYHA class II, 20 in class III) and 22 sex-matched post myocardial infarction patients without left ventricular dysfunction who served as controls. CHF patients underwent right heart catheteriz...
متن کاملRespiratory muscle weakness in Addison's disease.
Comment Evidence of thyroid autoimmunity has often been noted in patients who develop hypothyroidism while receiving amiodarone.2 Between 30% and 50% of patients who have hypothyroidism induced by amiodarone iodine have antithyroid antibodies.' 2 Antithyroid antibodies are less common in patients who have hyperthyroidism induced by amiodarone iodine. Monteiro et al reported the development of a...
متن کاملVentilatory drive and ventilatory response during rebreathing.
Maranetra, N. and Pain, M. C. F. (1974). Thorax, 29, 578-581. Ventilatory drive and ventilatory response during rebreathing. The increase in inspiratory airway pressure generated against a transiently occluded airway during rebreathing is proposed as a simple index of ventilatory drive (zlP/dPCO2). A study of this index in 12 normal subjects and 50 patients with chronic airways obstruction demo...
