一、概述目前,拍摄胸腹部X线片,传统作法是:X线机操作人员首先要求能够自主呼吸的患者要做拍片前的吸气训练,待患者吸足气后,憋住气不动,操作人员即按手动开关,而获得满意的吸气相。但是,对不能控制自主呼吸的患者,如婴幼儿、呼吸功能障碍的危重患者以及聋哑人、昏迷患者等,为其拍摄胸、腹部片时,X线操作人员只能观察片刻患者的呼吸规则,凭工作经验选择曝光时机,按动手动开关进行曝光。单靠这种办法曝光,带有很大的盲目性,很难准确掌握最佳曝光时机,尤其是失去自主控制,呼吸功能障碍的危重患者,呼吸根本没有规则可寻,给X线操作人员带来很大的困难,有时还会造成多次废片。
First, an overview At present, the filming of chest and abdomen X-ray film, the traditional practice is: X-ray machine operator first request to be able to spontaneously breathing patients to do before the filming of the inspiratory training, until the patient suction enough gas, hold back the gas does not move, Operators press the manual switch to obtain a satisfactory inspiratory phase. However, for those who can not control spontaneous breathing, such as infants and young children, critically ill patients with respiratory dysfunction, and deaf mute, coma patients, for its chest and abdomen film, X-ray operator can only observe a moment of breathing rules , With the experience of work choose the timing of exposure, press the manual switch for exposure. Exposure alone, with great blindness, it is difficult to accurately grasp the best timing of exposure, especially in critically ill patients with loss of self-control, respiratory dysfunction, breathing no rules to be found, to the X-ray operator with To great difficulties, and sometimes cause multiple scrap pieces.
