PRVC通气模式在AECOPD患者中的应用

摘要

Objective To explore the Pressure Regulated Volume Control Ventilation (PRVC) model of senile acute exacerbation of chronic obstructive pulmonary disease (AECOPD) the clinical curative effect and prevention of lung barotrauma. Methods 49 cases of elderly AECOPD patients with tracheal intubation were randomly divided into experimental group (25 cases) and control group (24 cases). Patients with PRVC model for treatment, control group treated with synchronized intermittent ventilation (SIMV) instruction model. Results Two groups both can effectively increase the pH, PaO2, PaO2/FiO2, reduce the PCO2.Patients on mechanical ventilation treatment of airway pressure was lower than that in control group. Conclusion PRVC used in the treatment of elderly patients with AECOPD, while quickly improve arterial blood gas analysis, can maintain airway pressure, effectively reduce the lung barotrauma of the risk, is a kind of safe and effective protective ventilation mode.%目的：探讨压力调节容量控制通气（PRVC）模式治疗老年急性加重期慢性阻塞性肺疾病（AECOPD）的临床疗效，及对肺气压伤的预防作用。方法将49例老年AECOPD气管插管患者随机分为试验组和对照组，试验组以压力调节容量控制通气（PRVC）模式进行治疗，对照组以同步间歇指令通气（SIMV）模式治疗。结果2组均能迅速有效地提高pH、动脉氧分压（PaO2）和氧合指数（PaO2/FiO2），降低动脉二氧化碳分压（PaCO2）。试验组在机械通气治疗中气道压明显低于对照组。结论 PRVC用于治疗老年AECOPD患者，在迅速改善动脉血气分析的同时，能够保持气道内压，有效降低气压伤的发生风险，是一种安全有效的保护性通气模式。
