Abstract

A monitor includes a measurement line segment adapted to be coupled between a patient interface and a positive airway pressure device. The measurement line segment defines a gas flow path. A sensor includes two ports in communication with the gas flow path through the measurement line segment, and a recording device is adapted to record data collected by the sensor.

Claims

1. A monitor, comprising:

a measurement line segment adapted to be coupled between a patient interface and a positive airway pressure device, the measurement line segment defining a gas flow path;

a sensor including two ports in communication with the gas flow path through the measurement line segment; and

a recording device adapted to record data collected by the sensor.

2. The monitor according to claim 1, wherein the sensor includes a differential (Δ

p) pressure sensor.

3. The monitor according to claim 1, wherein the measurement line segment is provided to a housing.

4. The monitor according to claim 1, further comprising one or more additional sensors in communication with the gas flow path.

5. The monitor according to claim 4, wherein the one or more additional sensors includes a photo-plethysmography sensor, O₂ sensor, CO₂ sensor, and/or saturation sensor.

6. The monitor according to claim 1, further comprising an alarm or alert arising from a sensed parameter collected by the sensor.

7. The monitor according to claim 1, wherein the sensor includes dual limbs.

8. A ventilation system, comprising:

a positive airway pressure device;

a patient interface;

a breathing gas line segment to communicate the positive airway pressure device and the patient interface; and

a monitor according to claim 1, the monitor being in communication with the breathing gas line segment.

9. The ventilation system according to claim 8, further comprising an evaluation system configured to evaluate the recorded data collected by the sensor.

10. The ventilation system according to claim 8, wherein the evaluation system includes a PC.

11. The ventilation system according to claim 8, wherein the evaluation system is configured to provide at least one of a recommendation of alternate therapy, a prescription associated with the alternate therapy, and web-links to recommended devices.

12. The ventilation system according to claim 8, wherein the positive airway pressure device is adapted to provide CPAP and/or BiPAP therapy.

13. The ventilation system according to claim 8, wherein the system provides closed-loop therapy based on at least one sensed parameter.

14. A method for providing ventilation therapy, comprising:

measuring differential pressure along a gas flow path between a patient interface and a positive airway pressure device;

recording data derived from the differential pressure measurement;

providing the recorded data to an evaluation system;

evaluating the recorded data; and

where appropriate, adjusting ventilation therapy and/or prescribing an alternate therapy based on the evaluation of the recorded data.

15. The method according to claim 14, wherein the ventilation therapy includes CPAP and/or BiPAP therapy.
