The ventilatory response to CO2 was subdivided into that portion due to increasing rib cage expansion, and that due to increased diaphragmatic descent. Five children were studied, awake, and anesthetized with halothane, 0.8-0.9%. During anesthesia there was a 67+/-8% reduction (mean+/-SE) in the slope of the response of overall ventilation to an increase in(More)
The pattern of motion of the rib cage and abdomen/diaphragm was studied in three normal subjects during sleep. Sleep state was monitored by electroencephalograph and electrocculograph. Intercostal electromyographs (EMG's) were recorded from the second interspace parasternally. Abdominothoracic motion was monitored with magnetometers and these signals(More)
Forty-four patients scheduled for routine gynaecological surgery through a Pfannenstiel incision were given either nalbuphine or papaveretum as premedication, with hyoscine. Respiratory depression was measured by carbon dioxide rebreathing before and one hour after premedication. Both combinations produced significant respiratory depression as measured by(More)
