Problems solved by technology
The trouble breathing results from a collapse and hence obstruction of the pharynx (throat air passage).
When this occurs, at the least it disturbs sleep but can also cause cardiac arrest.
Those who suffer from OSA tend to have excessive daytime sleepiness, which can lead to lost productivity and accidents.
This is effective, but it can have some drawbacks.
For some patients with weakened pulmonary systems, breathing in and out with constant pressure may be labored.
This tends to be quite expensive, impractical, and uncomfortable.
But along with a great benefit, sending such devices home with patients creates some new issues.
This is very expensive and probably impractical given the number of those victimized by OSA.
In addition, when a patient has time-based variations this cannot be properly addressed by a sleep clinic.

Embodiment Construction
The present invention is a PAP (positive airway pressure) apparatus configured for use in the home and suitable for treatment of OSA (obstructive sleep apnea). A PAP device of the present invention can be a CPAP (continuous positive airway pressure) device or an IPAP / EPAP (inspiratory positive airway pressure / expiratory positive airway pressure) device. The PAP of the present invention operates or provides “treatment cycles” in multiple modes including a “standard” mode governed by a “standard” set of operating parameters and a “custom” mode governed by a “custom” set of operating parameters. A “treatment cycle” is essentially the complete cycle of “pressure profiles” provided to a patient during a sleep cycle. An example of a “treatment cycle” is discussed with respect to FIG. 9. A “pressure profile” is a pressure versus time applied by the PAP device. Examples of pressure profiles are described with respect to FIGS. 9, 9a, 9b, and 9c.
The PAP apparatus of the present invention inc...

A method and apparatus for the optimized treatment of obstructive sleep apnea includes a controller coupled to an information storage device, a sensor and a pressure source. The pressure source is coupled to a patient airway. The controller reads information from the information storage device that represents a first operating mode defining a first pressure profile. The controller operates the pressure source to apply the pressure profile to the patient airway. The sensor generates a signal in response to changes in airflow in the patient airway. The controller analyzes the signal and selects a new operating mode in response to the analysis.
Description
FIELD OF THE INVENTIONThe present invention relates to the treatment of sleep disorders. More particularly, the present invention relates to a method and apparatus for optimizing the treatment of obstructive sleep apnea.BACKGROUNDOSA (obstructive sleep apnea) is a disease that adversely affects an estimated more than 10 million adults in the United States alone. The disorder manifests itself when a person has repeated trouble breathing at night. The trouble breathing results from a collapse and hence obstruction of the pharynx (throat air passage). When this occurs, at the least it disturbs sleep but can also cause cardiac arrest. Those who suffer from OSA tend to have excessive daytime sleepiness, which can lead to lost productivity and accidents.The best method for treating OSA is with a device that provides PAP (positive airway pressure) to a patient at night. The patient typically wears a mask such as a mask that fits over the nose. The mask is pressurized with a gas such as air...
