Abstract
Background : Since the late 1960s, mechanical ventilation has been accomplished primarily using volume controlled ventilation(VCV). While VCV allows a set tidal volume to be guaranteed, VCV could bring about excessive airway pressures that may be lead to barotrauma in the patients with acute lung injury. With the increment of knowledge related to ventilator-induced lung injury, pressure controlled ventilation(PCV) has been frequently applied to these patients. But, PCV has a disadvantage of variable tidal volume delivery as pulmonary impedance changes. Since the concept of combining the positive attributes of VCV and PCV(dual control ventilation, DCV) was described firstly in 1992, a few DCV modes were introduced. Pressure-regulated volume control(PRVC) mode, a kind of DCV, is pressure-limited, time-cycled ventilation that uses tidal volume as a feedback control for continuously adjusting the pressure limit However, no clinical studies were published on the efficacy of PRVC until now. 'This investigation studied the efficacy of PRVC in the patients with unstable respiratory mechanics. Methods : The subjects were 8 mechanically ventilated patients(M : F=6 : 2,
연구배경 : 일정한 분시 유지하면서도 기도압의 하나인 압력조절용적조정양식(PRVC)의 입상적 유용성에 대한 보고는 없었다. 본 연구는 호흡역학이 불안정한 환자에서 PRVC 양식이 원래의 개발 목적대로 압력 조절 양식에 비해 일호흡량을 일정하게 유지하면서 용적조절양식에 비해 기도압을 낮게 유지하는지를 관찰하였다. 연구방법 : 기계 호흡 중이며 활력징후의 안정을 보이는 환자 중 15분간 관찰 결과 VCV에서 최고 홉기압의 변이계수가 10이상으로 최고 홉기압의 변화가 심하거나, PCV에서 상시 호흡량의 변이계수가 10이상으로 일 호흡량의 변화가 심한 환자 8 명(남 : 녀=6 : 2,
