Abstract
Objective To compare the effect of average volume assured pressure suppont (AVAPS) mode and spontaneous breathing and time control (ST) mode in the treatment of patients with respiratory failure. Method Retrospectively analyzed the therapeutic effects of 63 patients with respiratory failure from October 2014 to October 2016, 3 patients were excluded during the course of treatment, and 60 patients included in the analysis were randomly divided into study group and control group. Study group patients were treated with AVAPS mode, control group patients were treated with ST mode. Before treatment and 24 hours and 4 days after treatment, the arterial partial pressure of carbon (PaCO2), arterial partial pressure of oxygen (PaO2), actual bicarbonate (AB) level were compared between the two groups. Before treatment and 4 days after treatment, respiratory rate, heart rate, forced expiratory volume in first second (FEV1), FEV1/forced vital capacity (FVC) and FEV1% prediction were compared between the two groups. The incidence of adverse reaction were compared between the two groups 4 days after treatment. Result PaCO2, PaO2, arterial blood pH and AB level were not significantly different between the two groups (P > 0.05). PaCO2 and PaO2 were significantly improved (P < 0.05) and arterial blood pH and AB level were not significantly improved 24 hours and 4 days after treatment inside each group (P > 0.05). The respiratory rate and heart rate of the two groups were significantly lower than before treatment (P < 0.05). The FEV1, FEV1/FVC and FEV1% prediction of the two groups were significantly higher than before treatment (P < 0.05). The incidence rates of adverse reaction of study group were significantly lower than control group 4 days after treatment (P < 0.05). Conclusion AVAPS mode is better than ST mode in the treatment of respiratory failure, fewer adverse reactions makes it safe and reliable.关键词
