摘要We have studied the respiratory effects of 5 and 10 cmH(2)O pressure support ventilation during anaesthesia with 1.5% end-tidal concentration of isoflurane in nine healthy, spontaneously breathing, adult patients. Some of the patients demonstrated an irregular respiratory pattern with periods of apnoea and we therefore went on to study a further seven patients with a continuous 500 s recording of airflow. Pressure support ventilation augmented mean (SD) tidal volume from 212 (56) ml to 350 (88) ml at 5 cmH(2)O and to 509 (108) ml at 10 cmH(2)O (n = 16, p < 0.05). Mean (SD) respiratory rate decreased from 26 (6) min(-1) to 22 (6) min(-1) at 5 cmH(2)O and 17(5) min(-1) at 10 cmH(2)O pressure support (n = 16, p < 0.05). Mean (SD) inspiratory work of breathing decreased from 1.77 (0.70) J. min(-1) to 0.31 (0.36) J min(-1) at 10 cmH(2)O pressure support ventilation (n = 9, p < 0.05). Analysis of the respiratory rhythm in the second group ow seven patients revealed on oscillating respiratory pattern in four patients at 5 cmH(2)O and six of the seven patients at 10 cmH(2)O pressure support ventilation. The metabolic advantage of the decreased work of breathing during pressure support ventilation during and anaesthesia is unlikely to balance the disadvantage of an oscillating respiratory rhythm.
