Benefits of technology

[0014] In a preferred embodiment, a portable adaptive control system is provided which continually searches for the optimal minimum pressure required to adequately distend a patient's nasal pharyngeal airway. By rendering the system portable, a large percentage of OSA victims can be cost-effectively treated in their homes, thus reducing the overcrowding in expensive hospital sleep centers. Optimal minimum pressure is used because higher pressures increase the likelihood of side effects (e.g., daytime rhinitis), and reduce the likelihood of patient compliance. A patient's compliance in regularly using the system is a significant concern inasmuch as the system is a portable device used at the patient's home without the supervision of a hospital sleep center specialist.

Problems solved by technology

Optimal minimum pressure is used because higher pressures increase the likelihood of side effects (e.g., daytime rhinitis), and reduce the likelihood of patient compliance.

Embodiment Construction

1. Overview

[0026] In accordance with a preferred embodiment, the present invention relates to an auto-CPAP system for adaptively providing continuous positive airway pressure in an upper airway system (e.g., pharyngeal airway of a patient). The auto-CPAP system performs detection, analysis, and decision-making functions.

2. System Description

[0027] As illustrated in FIG. 1a, an exemplary system is generally labelled 2 and includes means for detecting airflow from the CPAP device. The means of detecting airflow is shown in FIG. 1a to include a pneumotach 8 for measuring instantaneous airflow. The pneumotach includes a pressure transducer and an amplifier for generating an electric signal proportional to airflow.

[0028] Airflow is used to assess the respiratory and dynamic mechanical characteristics of a patient's pharyngeal airway (PA) during sleep and to adjust the therapeutic CPAP pressure as required. Total airflow is the sum of non-respiratory and respiratory airflow. The non...

Abstract

The present invention relates to systems and methods for automatically and continuously regulating the level of nasal pressure to an optimal value during OSA treatment. OSA therapy is implemented by a device which automatically re-evaluates an applied pressure and continually searches for a minimum pressure required to adequately distend a patient's pharyngeal airway. For example, this optimal level varies with body position and stage of sleep throughout the night. In addition, this level varies depending upon the patient's body weight and whether or not alcohol or sleeping medicine has been ingested.

Description

RELATED APPLICATION [0001] This application is a continuation of application Ser. No. 07 / 868,199 filed Apr. 14, 1992, which is a continuation of application Ser. No. 07 / 791,733 filed Nov. 14, 1991, now abandoned, both of which are incorporated herein by reference.BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates generally to systems and methods for treating sleep disorders. More particularly, the invention relates to systems and methods for treating obstructive sleep apnea using an adaptive control system for applying air pressure to the nasal airway. [0004] 2. State of the Art [0005] Obstructive sleep apnea (OSL) is a newly recognized disease that victimizes 15% of adult males. The disorder arises during sleep when the victim undergoes repeated cessation of breathing. This cessation results from an obstruction of the throat air passage (pharynx) due to a collapse of the throat air passage. Repeated cessation of breathing reduces blood...
