Evaluation of the effectiveness of external percussion and vibroacoustic chest massage in respiratory rehabilitation in cardiac surgery patients.

A randomized prospective study included 90 patients who underwent elective cardiac surgery. Vibroacoustic lung massage (VLM- 1-st group, 30 people) was performed with VibroLUNG device, high-frequency percussion of the chest followed by the intermittent airway pressure (HFP+IP) by Comfort Cough Plus device was performed in the 2nd group (30 patients). Procedures were performed 10-12 hours after extubation 3 times a day during 3 days after surgery. The 3rd group ( 30 people) is a control group. The following parameters were measured: SpO2, maximum inspiration volume (MIV) with used an incentive spirometer Coach-2 , and some volumetric parameters with used a portable spirometer Spiro Scout before and after every procedure on the 1st and 3rd days (on room air).本项随机前瞻性研究共纳入90例行择期心脏手术的患者。其中第一组（30例）采用VibroLUNG设备实施振动声肺按摩（Vibroacoustic lung massage, VLM）；第二组（30例）采用Comfort Cough Plus设备实施高频胸部叩击联合间歇气道压力通气（high-frequency percussion of the chest followed by the intermittent airway pressure, HFP+IP）；第三组（30例）为对照组。干预操作于术后拔管后10~12小时开始，每日3次，持续3天。本研究测量的指标包括：血氧饱和度（SpO2）、使用激励式肺量计Coach-2测得的最大吸气量（maximum inspiration volume, MIV），以及使用便携式肺量计Spiro Scout测得的部分容积参数；所有指标分别于第1天和第3天的每次操作前后，在室内空气环境下进行采集。
