Split-night sleep diagnostic system
First Claim
1. A split-night sleep diagnostic system for diagnosing and treating sleep apnea in a single night, comprising:
- a blower;
a respiratory interface;
a conduit connected between said blower and said respiratory interface; and
a valve disposed along said conduit, said valve including an aperture formed in said conduit between said blower and said respiratory interface, and a valve member movable between a first position partially occluding said conduit so that air flows through said aperture and a second position blocking said aperture so that continuous positive airway pressure is provided to a patient.

Abstract
A split-night sleep diagnostic system is provided for diagnosing and treating sleep apnea in a single night. The diagnostic system includes a blower, a respiratory interface and a conduit connected between the blower and the respiratory interface. Also included is a valve disposed along the conduit. The valve includes an aperture formed in the conduit between the blower and the respiratory interface, and a valve member movable between a first position partially occluding the conduit so that air flows through the aperture and a second position blocking the aperture so that continuous positive airway pressure is provided to a patient. Both diagnosis and titration can be performed using a single system at a single location over the course of a single night.

14. A device usable with an existing continuous positive airway pressure (CPAP) system that includes a conduit connected between a blower and a respiratory interface for modifying the operation of the CPAP system, comprising:
a valve disposed along said conduit, said valve including an aperture formed in said conduit between said blower and said respiratory interface, and a valve member movable between a first position partially occluding said conduit so that air flows through said aperture and a second position blocking said aperture so that continuous positive airway pressure is provided to a patient. - View Dependent Claims (15)

16. A device usable with an existing continuous positive airway pressure (CPAP) system that includes a conduit connected between a blower and a respiratory interface for modifying the operation of the CPAP system, comprising:
a valve disposed along said conduit, said valve including a valve stopper and at least two or more apertures formed in a valve body such that when said apertures are unobstructed or partially obstructed with said valve stopper, air flows through said apertures and when said apertures are obstructed with said valve stopper, continuous positive airway pressure is provided to a patient. - View Dependent Claims (17)

18. A method of diagnosing and treating sleep apnea in a single night using a system having a conduit with a valve, said method comprising the steps of:
-
monitoring a patient'"'"'s breathing with the valve open for a first portion of the night; and
providing continuous positive airway pressure with the valve closed for a second portion of the night. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
