Airway obstruction during exercise and isocapnic hyperventilation in asthmatic subjects.
We compared pulmonary mechanics measured during long-term exercise (LTX = 20 min) with long-term isocapnic hyperventilation (LTIH = 20 min) in the same asthmatic individuals (n = 6). Peak expiratory flow (PEF) and forced expiratory volume in 1 s (FEV(1)) decreased during LTX (-19.7 and -22.0%, respectively) and during LTIH (-6.66 and 10. 9%, respectively). In contrast, inspiratory pulmonary res...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Isocapnic hyperventilation increases carbon monoxide elimination and oxygen delivery.
Hyperventilation with mixtures of O2 and CO2 has long been known to enhance carbon monoxide (CO) elimination at low HbCO levels in animals and humans. The effect of this therapy on oxygen delivery (DO2) has not been studied. Isocapnic hyperventilation utilizing mechanical ventilation may decrease cardiac output and therefore decrease DO2 while increasing CO elimination. We studied the effects o...
متن کاملIsocapnic hyperpnoea accelerates recovery from isoflurane anaesthesia.
BACKGROUND Hyperventilation should speed up elimination of volatile anaesthetic agents from the body, but hyperventilation usually results in hypocapnia. We compared recovery from isoflurane anaesthesia in patients allowed to recover with assisted spontaneous ventilation (control) and those treated with isocapnic hyperpnoea. METHODS Fourteen patients were studied after approximately 1 h of an...
متن کاملChanges in mucociliary clearance during and after isocapnic hyperventilation in asthmatic and healthy subjects.
Hyperpnoea with dry air could lead to a reduction in depth and hyperosmolarity of the periciliary fluid layer (PFL) as a consequence of evaporative water loss. We investigated whether mucociliary clearance (MCC) is likely to be affected by dry air hyperpnoea, which also results in airway narrowing in asthmatics. MCC was measured by radioaerosol technique, for about 1 h, in 10 asthmatic and 8 he...
