气道平均压(mean airway pressure-MAP)并不是一次呼吸周期间的气道压力平均值,而是某一时限内几次机械通气(存在自主呼吸时)和自主呼吸期间在呼吸道近端检测的气道压力平均值。一般由呼吸道近端检测的通气压力波曲线下的面积除以所占的时间,通过积分法计算测出。此为近年来用于机械通气期间监测通气和氧合效果的一项较为理想的监护指标。气道平均压监测的临床意义虽然在治疗新生儿肺透明膜病(HMD)等严重肺部疾患时应用呼吸器已有数十年历史,但是在如何调
Mean airway pressure-MAP is not an average of airway pressure over a single breath, but is measured over several times of mechanical ventilation over a period of time (with spontaneous respiration) and at the proximal end of the respiratory tract during spontaneous breathing Airway pressure average. Generally by the proximal respiratory tract detection of ventilation pressure wave area divided by the area occupied by the time, calculated by the integral method. This is an ideal indicator of monitoring ventilation and oxygenation during mechanical ventilation in recent years. Clinical Significance of Airway Mean Pressure Monitoring Although respirators have been used for decades in the treatment of severe lung disorders such as neonatal hyaline membrane disease (HMD),
