摘要： A chest drainage system including a collection device configured to receive fluid from the pleural cavity of a patient. A sensor is included to detect a pressure differential in the fluid. A display is configured to display a trend in occurrences of changes in pressure of the fluid over time in predetermined time increments based on a number of detections of pressure differentials that exceed a predetermined pressure differential during each of the predetermined time increments. The trend is correlative to the percentage of time that the patient is deemed to have an air leak in the pleural cavity in the predetermined time increments. The trend is derived from a ratio of the quantity of respiratory cycles of the patient for which the predetermined pressure differential is detected (QRCleak) in the predetermined time increments to the total quantity of respiratory cycles of the patient in respective predetermined time increments (QRCtotal).
摘要翻译： 胸部引流系统，其包括构造成从患者的胸膜腔接收流体的收集装置。 包括传感器以检测流体中的压力差。 显示器被配置为基于在每个预定时间增量期间超过预定压力差的压力差的检测次数，以预定的时间增量显示流体随着时间的压力变化发生的趋势。 该趋势与患者被认为在预定时间增量中在胸腔中具有空气泄漏的时间百分比相关。 趋势来自于以预定时间增量检测到预定压力差异的患者的呼吸循环量（QRCleak）与患者的各个预定时间增量（QRC总计）的呼吸周期总数的比率， 。
