Abstract

An apparatus for treatment of a patient with both sleep-disordered breathing and diabetes includes: a blower configured to provide a supply of air at positive pressure; a patient interface; headgear to hold the patient interface in position in communication with a patient'"'"'s airways; at least one hypoglycemia sensor; an alarm; and a controller, wherein the controller is programmed to receive a signal from the at least one hypoglycemia detector, analyze the signal for indications of hypoglycemia and upon detection of an indication of hypoglycemia trigger the alarm.

Claims

1. An apparatus for treatment of a patient with both sleep-disordered breathing and diabetes, comprising:

a flow generator configured to provide a supply of air at positive pressure;

a patient interface including a mask;

headgear adapted to hold the patient interface in position in communication with a patient'"'"'s airways;

at least one glycemia abnormality detector including a sensor for communication with mucosal regions of the patient'"'"'s nares;

an alarm; and

a controller,

wherein the controller is programmed to receive a signal from the at least one glycemia abnormality detector, analyze the signal for indications of glycemia abnormality and, upon detection of an indication of glycemia abnormality, trigger the alarm.

2. The apparatus according to claim 1, wherein said at least one glycemia abnormality detector is further configured to detect activation of the sympathetic nervous system.

3. The apparatus according to claim 1, wherein said at least one glycemia abnormality detector is further configured to detect at least one of:

patient sweating, temperature, heart rate, and respiration rate.

4. The apparatus according to claim 1, further comprising a flow sensor in fluid communication with the patient interface.

5. The apparatus according to claim 1, wherein said alarm is local to the patient interface.

6. The apparatus according to claim 1 wherein said alarm is sent to a remote monitoring system.

7. The apparatus according to claim 1, wherein the alarm is operable to sound an audible alert when the signal indicates the glycemia abnormality.

8. The apparatus according to claim 1, wherein the controller is configured to transmit information to a remote location when the signal indicates one or more of:

hypoglycemia, hyperglycemia, and diabetic coma.

9. The apparatus according to claim 1, further comprising a drug delivery unit.

10. The apparatus according to claim 9, wherein the drug delivery unit is configured to supply at least one of glucose and insulin to the patient.

11. A method of treating a patient with both sleep-disordered breathing and diabetes, the method comprising:

providing a supply of pressurized breathable gas to the patient through a mask using a PAP device; and

,

generating a signal indicative of whether the patient is experiencing a diabetic event, the signal being based on data gathered from (a) a first sensor in contact with mucosal regions of the patient'"'"'s nares, and (b) a second sensor built into headgear that is adapted to hold the mask in a position suitable for communicating the supply of pressurized breathable gas to the patient'"'"'s airways.

12. The method according to claim 11, further comprising when the signal indicates that the patient is experiencing a diabetic event, activating an alert mechanism.

13. The method according to claim 12, wherein the activating of the alert mechanism is further practiced by sounding an audible alarm.

14. The method according to claim 12, wherein the activating of the alert mechanism is further practiced by notifying a remote monitoring station.

15. The method according to claim 11, further comprising when the signal indicates that the patient is experiencing a diabetic event, administering a corresponding treatment.

16. An apparatus for treatment of a patient with both sleep-disordered breathing and diabetes, comprising:

a PAP device configured to provide a supply of pressurized breathable gas for sleep-disordered breathing treatment;

at least one glycemia detector, wherein the at least one glycemia detector includes a sensor for contact with mucosal regions of the patient;

an action unit including a drug delivery unit for use in treating the patient'"'"'s diabetes; and

a controller integrated into the PAP device and operable to receive a signal from the at least one glycemia detector, analyze the signal for an indication of a glycemia abnormality, and instruct the drug delivery unit to provide a treatment to the patient for the glycemia abnormality while also instructing the PAP device to provide the supply of pressurized breathable gas.

17. The apparatus according to claim 16, wherein the drug delivery unit is configured to provide at least one of oral insulin and glucose to the patient upon receiving instructions from the controller.

18. The apparatus according to claim 16, wherein the drug delivery unit configured to provide the treatment to the patient for the glycemia abnormality in at least one of vapor form and through aerosol delivery.

19. The apparatus according to claim 16, wherein the drug delivery unit is configured to provide at least one of insulin and glucose to the patient in at least one of vapor form and through aerosol delivery upon receiving instructions from the controller.

20. The apparatus according to claim 16, wherein said glycemia detector is further configured to detect activation of the sympathetic nervous system.
