临床上常应用简易呼吸囊行心肺复苏及人工呼吸急救。但不能确定单手、双手挤压方法对不同容量简易呼吸囊输出潮气量的影响 ,并有可能造成通气不足或通气过度。我们分别采用单手、双手挤压方法对 10 0 0、15 0 0、2 0 0 0ml容量不同的简易呼吸囊输出潮气量进行测量 ,现报告如下? Clinically often used simple resuscitation cardiopulmonary resuscitation and resuscitation of artificial respiration. However, the effect of one-handed and two-handed squeezing on the tidal volume output by simple breath sacs of different capacities can not be determined and may cause hypoventilation or hyperventilation. We used single-handed, two-hand squeeze method of different volumes of 100 000,1500 0,2 0 0 0ml capacity of the simple respiratory capsule output tidal volume measurements are reported as follows?
