A microvolumetric noninvasive sensor is described for the monitoring of minimal respiration in adults, children, and infants. The monitor, designated a diaphragm sensor, has been applied since 1965 in the clinical management of optimal ventilation and relaxant drug administration. As an inspiratory monitor in the curarized patient, the sensor responds quantitatively to persisting spontaneous tidal volumes of 1 ml. or more. This minimal respiration is observed between controlled lung inflations. The monitor also indicates small outboard circuit leaks and responds to cardiac pulsations when respiratory deflections disappear after succinylcholine administration or hyperventilation. Applications include easy maintenance of ventilation near or below the patient's carbon dioxide (CO2) apneic threshold despite curarization and the assessment of diaphragm paralysis when the CO2 drive is maintained slightly above threshold. In continuous routine use, the diaphragm sensor provides the anesthesiologist with a quantitative monitor of persisting spontaneous respiratory activity.
描述了一种用于监测成人、儿童和婴儿微小呼吸的微体积无创传感器。该监测器被称为膈肌传感器，自1965年以来一直应用于最佳通气和松弛药物给药的临床管理中。作为箭毒化患者的吸气监测器，该传感器对持续的1毫升或更大的自发潮气量进行定量响应。这种微小呼吸在控制性肺充气之间观察到。该监测器还可指示小的外部回路泄漏，并在琥珀酰胆碱给药或过度通气后呼吸偏转消失时对心脏搏动作出响应。其应用包括尽管箭毒化，但仍能轻松维持通气接近或低于患者的二氧化碳（CO2）呼吸暂停阈值，以及在CO2驱动维持在略高于阈值时评估膈肌麻痹。在连续常规使用中，膈肌传感器为麻醉医生提供了对持续自发呼吸活动的定量监测。
