Pressure-controlled ventilation improves oxygenation during laparoscopic obesity surgery compared with volume-controlled ventilation.
BACKGROUND We compared pressure and volume-controlled ventilation (PCV and VCV) in morbidly obese patients undergoing laparoscopic gastric banding surgery. METHODS Thirty-six patients, BMI>35 kg m(-2), no major obstructive or restrictive respiratory disorder, and Pa(CO(2))<6.0 kPa, were randomized to receive either VCV or PCV during the surgery. Ventilation settings followed two distinct algo...
متن کاملComparison of volume controlled with pressure controlled ventilation during one-lung anaesthesia.
Pressure controlled ventilation (PCV) is an alternative mode of ventilation which is used widely in severe respiratory failure. In this study, PCV was used for one-lung anaesthesia and its effects on airway pressures, arterial oxygenation and haemodynamic state were compared with volume controlled ventilation (VCV). We studied 48 patients undergoing thoracotomy. After two-lung ventilation with ...
متن کاملVentilation and arterial oxygenation during thoracic surgery.
Considerable interest has been shown in recent years in the relative distributions of alveolar blood and gas flows under various conditions. During thoracic surgical procedures in the lateral position, with one hemithorax open and with controlled ventilation of the lungs, a severe degree of maldistribution of blood and gas may be expected. The upper lung may be freely expanded, retracted by the...
متن کاملMechanical ventilation during extracorporeal membrane oxygenation
The timing of extracorporeal membrane oxygenation (ECMO) initiation and its outcome in the management of respiratory and cardiac failure have received considerable attention, but very little attention has been given to mechanical ventilation during ECMO. Mechanical ventilation settings in non-ECMO studies have been shown to have an effect on survival and may also have contributed to a treatment...
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...
