Changes in functional residual capacity during cardiac surgery.
A gas washout technique was used to measure the functional residual capacity (FRC) in eight patients during anaesthesia for cardiac surgery. The patients were anaesthetized with droperidol, fentanyl and nitrous oxide, alcuronium was given and the lungs were ventilated with a volume controlled ventilator. FRC was measured at three stages before skin incision, after sternotomy but before cardiopu...
متن کاملFunctional residual capacity during anaesthesia. I: Methodology.
The helium dilution technique for the measurement of functional residual capacity (FRC) is reviewed with special reference to anaesthesia. A modification is described which permits measurements to be made during intermittent positive pressure ventilation. This modification causes minimal interference with the circuit as it is used for spontaneous respiration. The measuring circuit may be altern...
متن کاملBedside-measurements of electrical impedance tomography and functional residual capacity during positioning therapy in a case of acute respiratory failure
The lungs of patients with Acute Respiratory Failure (ARF) are characterized by reduced lung volume and regional heterogeneity of ventilation distribution. To improve lung volume and ventilation distribution, protective mechanical ventilation with positive end-expiratory pressure (PEEP), recruitment maneuvers, and some adjunct measures like intermittent proning have been recommended. But the co...
متن کاملPerioperative changes in functional residual capacity in morbidly obese patients.
Functional residual capacity (FRC) was measured before and after induction of anaesthesia for jejunoileal bypass surgery in 30 morbidly obese patients. The onset of anaesthesia was associated with a 51% reduction in FRC from 2.2 litre to 1.0 litre. Eighteen of the patients were investigated more extensively; in these subjects FRC was reduced below the control values of residual volume (RV) with...
متن کاملRespiratory changes during defecation in patients with chronic respiratory failure.
Oxygen (O2) desaturation may occur in patients affected by respiratory diseases during daily activities, although most of these activities, e.g. walking, washing and cooking, can be avoided or eventually performed with an external aid. In this prospective study, the respiratory changes induced by the mandatory effort of defecation were assessed in patients with chronic respiratory insufficiency...
