CONTINUOUS POSITIVE AIRWAY PRESSURE THERAPY TARGET PRESSURE COMFORT SIGNATURE

摘要

A comfort signature that naturally adapts delivered pressure to patient breathing by measuring comfort directly from the source is disclosed. Pressure is measured at the patient interface and is used to provide a comfortable and suitable target pressure adjustment that is synchronized with patient respiration.

主权项

1. A method for adjusting continuous positive airway pressure (CPAP) therapy for patient comfort on a respiratory assistance device, the method comprising:
setting a target delivery pressure to a prescription pressure level; generating on the respiratory assistance device an output of therapeutic gas to an airway of the patient in pneumatic communication therewith over a patient interface, pressure of the output corresponding to the target delivery pressure as set to the prescription pressure level; receiving on the respiratory assistance device patient pressure values measured at the patient interface; detecting a minimum value among the received patient pressure values over a first predetermined time period; and reducing the target delivery pressure following a predefined delay after detecting the minimum value of the received patient pressure values until the target delivery pressure is below a contemporaneously measured patient pressure value.
