Abstract

Systems and method for monitoring patient physiological data are presented herein. A gas analyzing measurement head can be provided to sample and analyze respiratory gases of a patient. In one embodiment, the gas analyzing measurement head can read information on an information element of an airway adapter or resuscitation bag. Such information can be used to generate instructions for manual ventilation using the gas analyzing measurement head, airway adapter, and resuscitation bag. Manual ventilation instructions can be displayed on the gas analyzing measurement head or can be transmitted for display on another device, such as a clinician'"'"'s mobile computing device.

Claims

25. (canceled)

26. A physiological monitor including an electronic display device, which provides respiration guidance to assist in timing respiration events, the physiological monitor comprising:

at least one sensor configured to measure information responsive to at least one physiological parameter;

at least one processor configured to provide guidance for respiration event sequences; and

a display configured to provide a visual indication of the guidance, the visual indication comprising a graphic that expands and contracts to indicate a timing of a desired respiratory sequence.

27. The physiological monitor of claim 26, wherein the display device is a smartphone.

28. The physiological monitor of claim 26, further comprising a first housing for the sensor and a second housing for the display.

29. The physiological monitor of claim 26, wherein the graphic comprises a plurality of circles.

30. The physiological monitor of claim 26, wherein the at least one processor is further configured to detect a time of performance of the respiration event sequences;

and generate feedback for the user based on a predetermined rate and the detected time of performance.

31. The physiological monitor of claim 30, wherein the predetermined rate is based on reminder settings corresponding to certain time or cycle.

32. The physiological monitor of claim 26, wherein the respiration event sequences correspond to cardiopulmonary resuscitation (CPR).

33. The physiological monitor of claim 26, wherein the physiological parameter comprises respiration rate and wherein the at least one processor is configured to determine that the respiration rate of the user is outside of threshold readings and select guidance based on the determination.

34. The physiological monitor of claim 26, wherein the guidance includes a rate of conducting the respiration event sequences and wherein the at least one processor is further configured to generate stimulatory feedback to guide the user to follow the rate.

35. The physiological monitor of claim 34, wherein the at least one processor is configured to update the rate based on the determined physiological parameter.

36. The physiological monitor of claim 34, wherein the stimulatory feedback includes a vibrational feedback.
