First Claim
1. A method for diagnosing a cardiovascular-related condition in a breathing person, the method comprising:
- interfacing a valve system to the person'"'"'s airway, the valve system being configured to decrease or prevent respiratory gas flow to the person'"'"'s lungs during at least a portion of an inhalation event;
permitting the person to inhale and exhale through the valve system, wherein during inhalation the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure;
measuring at least one physiological parameter while the person inhales and exhales through the valve system, and evaluating the measured parameter to diagnose a cardiovascular condition.

Abstract
One method for diagnosing a cardiovascular-related condition in a breathing person comprises interfacing a valve system to the person'"'"'s airway. The valve system is configured to decrease or prevent respiratory gas flow to the person'"'"'s lungs during at least a portion of an inhalation event. The person is permitted to inhale and exhale through the valve system. During inhalation, the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure. Further, at least one physiological parameter is measured while the person inhales and exhales through the valve system. The measured parameter is evaluated to diagnose a cardiovascular condition.

11. A system for diagnosing a cardiovascular-related condition in a breathing person, the system comprising:
-
a valve system that is capable of being coupled to the person'"'"'s airway, the valve system being configured to decrease or prevent respiratory gas flow to the person'"'"'s lungs during at least a portion of an inhalation event to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure; and
a monitoring system to monitor changes in at least one physiological parameter while the person inhales and exhales through the valve system, wherein the monitoring system includes a computer for evaluating the measured parameter to diagnose a cardiovascular condition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)

21. A method for diagnosing a cardiovascular-related condition in a breathing person, the method comprising:
-
interfacing a valve system to the person'"'"'s airway, the valve system being configured to decrease or prevent respiratory gas flow to the person'"'"'s lungs during at least a portion of an inhalation event;
coupling a monitoring system to the person, wherein the monitoring system is configured to monitor changes in at least one physiological parameter while the person inhales and exhales through the valve system;
permitting the person to inhale and exhale through the valve system, wherein during inhalation the valve system functions to produce a vacuum within the thorax to increase blood flow back to the right heart of the person, thereby increasing blood circulation and blood pressure;
measuring at least one physiological parameter while the person inhales and exhales through the valve system using the monitoring system, and evaluating the measured parameter to diagnose a cardiovascular condition.
