The purpose of this study was to determine whether adult patients with chronic obstructive pulmonary disease (COPD) can safely perform pulmonary hygiene measures without compromising their arterial oxygen saturation (SaO2) levels (less than 80 per cent). In 15 male veterans with moderate-to-severe COPD an ear oximeter was used to measure SaO2 levels while subjects completed a series of percussion, deep breathing, and coughing maneuvers in the head-down position (50 degree angle). No clinically significant changes in SaO2 levels were found in 14 subjects during pulmonary hygiene measures, but potentially dangerous symptoms were noted in two subjects. Our study supports the monitoring of objective and subjective symptoms during pulmonary hygiene and discontinuance of the procedure if tachycardia, palpitations, dyspnea, chest pain, or other distressful symptoms occur that might indicate hypoxemia.
本研究的目的是确定患有慢性阻塞性肺疾病（COPD）的成年患者能否安全地进行肺部清洁措施，而不影响其动脉血氧饱和度（SaO2）水平（低于80%）。在15名中度至重度COPD男性退伍军人中，当受试者在头低脚高位（50度角）完成一系列叩击、深呼吸和咳嗽动作时，使用耳式血氧仪测量SaO2水平。在14名受试者进行肺部清洁措施期间，未发现SaO2水平有临床显著变化，但在两名受试者中观察到潜在的危险症状。我们的研究支持在肺部清洁期间监测客观和主观症状，并且如果出现可能表明低氧血症的心动过速、心悸、呼吸困难、胸痛或其他不适症状，则停止该操作。
