MONITORING AND CONTROL FOR A LARYNGEAL MASK AIRWAY DEVICE

摘要

The disclosed method of monitoring the cuff pressure of an LMAprovides an estimation of a patient's anesthetic state. Cuff pressure tends to rise and fall during IPPV and spontaneous breathing. One of the disclosed methods activates an alarm if an instantaneous value of the cuff pressure exceeds selected levels. This method may also automatically adjust the selected levels. One of the disclosed methods activates an alarm if activity of the cuff pressure as observed over a period of time exceeds a selected level.
