Pressure support ventilation during fibreoptic intubation under propofol anaesthesia.
GOAL OF THE STUDY To assess the benefit of pressure support ventilation during fibreoptic intubation performed under propofol anaesthesia in patients having an anticipated difficult intubation. PROCEDURES Thirty-two patients with ENT cancer, and having at least two criteria for anticipated difficult intubation were prospectively included. All patients received topical lidocaine 2% and propofo...
متن کاملIncreased ventilation requirements during obstetric general anaesthesia.
The inspiratory fresh gas flow rate (FGF) required to produce an end-tidal carbon dioxide tension (PE'CO2) of 4 kPa during general anaesthesia, neuromuscular blockade and artificial ventilation, was compared in a group of 46 obstetric patients and a matched group of 50 non-pregnant female patients. The non-pregnant patients required a mean (SD) inspiratory FGF of 77 (10.6) ml kg-1 min-1, wherea...
متن کاملComparison of the effect of pressure support ventilation and volume assured pressure support ventilation on weaning patients off mechanical ventilation after cardiac surgery
Background: Weaning from mechanical ventilation in the intensive care unit is an important step in the treatment process. More patients in less than 6 hours after cardiac surgery can be separated from mechanical ventilation and extubated. However, 20-40% of patients after cardiac surgery, due to dysfunctional ventilator weaning response (DVWR), still remain under mechanical ventilation. Therefo...
متن کاملThe effect of bi-level positive airway pressure mechanical ventilation on gas exchange during general anaesthesia.
BACKGROUND Atelectasis may occur and ventilation-perfusion mismatch may increase during general anaesthesia with neuromuscular paralysis and mechanical ventilation, though preservation of some intermittent muscle contraction might mitigate this process. There is still no ideal manoeuvre to minimize such mismatch or atelectasis. Bi-level positive airway pressure (BiPAP) ventilation adjusts to ex...
متن کاملRespiratory function during pressure support ventilation.
Pressure support ventilation (PSV) is a pressure assist form of mechanical ventilatory support that augments the patient's spontaneous inspiratory efforts with a clinician selected level of positive airway pressure. To understand the effects of PSV on respiratory function, experiments were performed on 15 stable patients requiring synchronized intermittent mandatory ventilation (SIMV), as well ...
