METHOD AND SYSTEM FOR DETECTING MOUTH LEAK DURING APPLICATION OF POSITIVE AIRWAY PRESSURE
摘要
<p>A method and system for providing therapeutic gas to a patient during positive airway pressure ventilation and, more particularly, detecting the presence of a mouth leak during ventilation and, upon the detection of a mouth leak, reducing the applied pressure so as to reduce irritation and discomfort experienced by the patient. Respiratory air flow from a patient is measured in a waveform as a function of time. An approximate value of the root mean square voltage of the waveform is established during a period in which the patient is experiencing a mouth leak and a root mean square voltage of the waveform is established during a period in which the patient is experiencing an apneic event. The waveform is subsequently monitored and the rate of respiratory airflow is decreased when there is an indication of a mouth leak provided there is no indication of an apneic event.</p>
