姿勢對氧合作用的影響及其臨床應用

Maintaining adequate oxygenation is very important to both acutely and chronically ill patients. Recently, many articles reported that positioning itself may affect gas distribution, diaphragmatic contraction, PaO2, and lung and thorax compliance. The entity and location of pulmonary dysfunction, type and Site of surgery, age, cardiac function and obesity may modify the effect of positioning on oxygenation. The chest physical therapy (CPT) techniques of postural drainage and positioning are frequently used in patients with retained secretions or decreased ability to cough in order to keep airway patency, prevent respiratory tract infection, and improve respiratory function. Because several patients developed arrhythmias during CPT, concerning the effect of this procedure on oxygenation has been raised. This paper reviewed the previous reports of the effect of various body positions on oxygenation and provided a ”sate of art” protocol for patient management.
