一、呼吸机的类型目前多应用正压呼吸机。正压呼吸机是在气道内给予正压通气,使肺膨胀,达到通气和换气的目的。其三种类型:①定容呼吸机:在患者气道内每次通气时给予一定量的潮气量,不管患者的气道阻力如何,给予的潮气量不变,如气道阻力过高,呼吸机上的报警装置就会发出信号。这种呼吸机适用于有肺部疾病的患者,如气道阻力增加的疾病(COPD、哮喘、肺部弹性改变)和胸壁弹性改变的疾病(肺间质纤维化等)。②定压呼吸机:呼吸机以固定的压力向气道内输送气体。定压呼吸机一般较灵巧、简便,但不适用于上述患者,因肺部的顺
First, the type of ventilator Positive pressure ventilator more applications. Positive pressure ventilator is to give positive pressure ventilation in the airway, so that the expansion of the lungs to achieve the purpose of ventilation and ventilation. The three types: constant volume ventilator: Each time in the patient’s airway ventilation to give a certain amount of tidal volume, regardless of the patient’s airway resistance, given the tidal volume unchanged, such as airway resistance is too high, the ventilator The alarm device will send a signal. This ventilator is suitable for patients with pulmonary diseases such as diseases with increased airway resistance (COPD, asthma, changes in lung elasticity) and diseases with altered chest wall (pulmonary interstitial fibrosis, etc.). ② constant pressure ventilator: ventilator with a fixed pressure to the airway gas delivery. Constant pressure ventilator generally more deft, simple, but does not apply to the above patients, due to the smooth lung
