Abstract

A method for treating a breathing person suffering from diabetes utilizes a valve system that is interfaced to the person's airway and 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 cardiac output and blood circulation in order to treat the person suffering from diabetes.

Claims (15)

1. A device for facilitating the treatment of a person suffering from diabetes, the device comprising:

a housing having an opening that is adapted to be interfaced with the person's airway; and

a valve system that is operable to regulate respiratory gas inflow through the housing and into the person's lungs due to spontaneous inhalation, the valve system assisting in manipulating intrathoracic pressures to increase blood flow back to the person's chest and thereby enhance vital organ perfusion and function;

wherein the valve system is configured to permit respiratory gases to flow to the person's lungs due to spontaneous inhalation when the negative intrathoracic pressure reaches a pressure in the range from about −3 cm H 2 O to about −10 cm H 2 O in order to treat the person suffering from diabetes.

2. A device as in claim 1 , wherein the valve system is further configured to regulate respiratory gas flow from the person's lungs during spontaneous exhalation to further assist in manipulating intrathoracic pressures to enhance vital organ perfusion and function.

3. A device as in claim 2 , wherein the valve system is configured to permit respiratory gases to flow from the person's lungs due to spontaneous exhalation when the intrathoracic pressure is in the range from about 0 cm H 2 O to about 7.5 cm H 2 O.

4. A device as in claim 1 , wherein valve system comprises an inflow valve that is selected from a group of valves consisting of a fish mouth valve, a spring-poppet valve, a ball valve, a flexible plug valve, a slotted airway resistance valve, a movable disk valve, a compressible airway valve, an iris valve and a sequential series of adjusting valves.

5. A device as in claim 1 , further comprising at least one physiological sensor that is attachable to the patient to monitor at least one physiological parameter of the person while spontaneously breathing through the valve system.

6. A device as in claim 1 , further comprising a facial mask coupled to the housing.

7. A device as in claim 1 , further comprising a mouthpiece coupled to the housing.

8. A device for facilitating the treatment of a person suffering from diabetes, the device comprising:

a housing having an opening that is adapted to be interfaced with the person's airway; and

a valve system that is operable to regulate respiratory gas inflow through the housing and into the person's lungs due to spontaneous inhalation, the valve system assisting in manipulating intrathoracic pressures to increase blood flow back to the person's chest and thereby enhance vital organ perfusion and function; and

at least one physiological sensor that is attachable to the patient to monitor at least one physiological parameter of the person while spontaneously breathing through the valve system;

wherein the valve system is configured to permit respiratory gases to flow to the person's lungs due to spontaneous inhalation when the negative intrathoracic pressure reaches a pressure in the range from about −3 cm H 2 O to about −10 cm H 2 O in order to treat the person suffering from diabetes.
