ABSTRACT:
The present invention provides for a method and apparatus for providing continuous positive airway pressure for treating sleep apnea. The method comprising the steps of providing a breathing gas flow to a subject, measuring a respiratory characteristic of the subject, determining or estimating a preferable breathing gas flow for the subject based on wavelet analysis utilizing in part the respiratory characteristic of the subject; and preferably adjusting the breathing gas flow if the determined or estimated preferable breathing gas flow is different. This method and apparatus can be used in a number of applications including both clinical and home use in the form of CPAP for the treatment of sleep apnea or less preferably as a ventilator to assist in patient breathing.
