Most mechanical ventilators display tracings of airway pressure (Paw) volume (V) and flow (V). In volume preset modes, Paw informs about the mechanical properties of the respiratory system and about the activity of respiratory muscles acting on the system. When monitoring ventilator waveforms, it is important to appropriately scale the tracing so that nuances in time profiles may be appreciated. In this short monograph, we offer three examples of how clinicians may use this information for patient assessment and care.
大多数机械通气机都会显示气道压力（Paw）、容积（V）和流量（V）的波形图。在容积预设模式下，气道压力能反映呼吸系统的力学特性以及作用于该系统的呼吸肌活动情况。在监测通气机波形时，正确调整波形图的比例很重要，这样才能看清时间变化曲线中的细微差别。在这本简短的专著中，我们提供三个实例，说明临床医生如何利用这些信息进行患者评估和护理。
