Abstract

According to an embodiment of the present invention, a ventilation monitoring device comprises at least one processor and at least one memory including computer program code. The at least one memory and the computer program code is configured with the at least one processor to cause the ventilation monitoring device to determine whether an intubated subject'"'"'s tracheal tube is properly placed by receiving an indication of a subject'"'"'s breath from at least one sensor.

Claims

1. A ventilation monitoring device, comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured with the at least one processor to cause the ventilation monitoring device to determine whether an intubated subject'"'"'s tracheal tube is properly placed by receiving an indication of a subject'"'"'s breath from at least one of a capnography sensor or at least two electrodes configured with the ventilation monitoring device to measure a transthoracic impedance of the subject, and receiving an indication of a positive result of an auscultation within a predetermined time limit.

2. The ventilation monitoring device of claim 1, further comprising a graphical user interface, wherein the indication of a positive result of an auscultation is received via the graphical user interface.

3. The ventilation monitoring device of claim 1, wherein the indication of a positive result of an auscultation comprises an indication of an auscultation of a subject'"'"'s left lung, right lung, left axillary, right axillary or abdomen.

4. The ventilation monitoring device of claim 1, wherein the ventilation monitoring device provides a prompt to a user upon expiration of the predetermined time limit.

5. The ventilation monitoring device of claim 1, wherein indication of the subject'"'"'s breath from the capnography sensor is selectable from a graphical user interface.

6. The ventilation monitoring device of claim 1, wherein indication of the subject'"'"'s breath from the at least two electrodes is selectable from a graphical user interface.

7. The ventilation monitoring device of claim 1, wherein indication of the subject'"'"'s breath from the capnography sensor and from the at least two electrodes is selectable from a graphical user interface.

8. The ventilation monitoring device of claim 1, wherein the device further includes an electrocardiogram (ECG) monitoring unit.

9. The ventilation monitoring device of claim 1, wherein the device further includes a defibrillation unit.

10. A method for determining whether a subject'"'"'s tracheal tube is properly placed, comprising:

receiving within a ventilation monitoring device an indication of a subject'"'"'s breath from at least one of a capnography sensor or at least two electrodes configured with the ventilation monitoring device to measure a transthoracic impedance of the subject; and

receiving within the ventilation monitoring device an indication of a positive result of an auscultation,

wherein receiving the indication of the positive result of the auscultation occurs within a predetermined time limit.

11. The method of claim 10, wherein a graphical user interface is configured to receive the at least one indication of a positive result of an auscultation.

12. The method of claim 10, wherein the indication of the positive result is related to an auscultation of a left lung, right lung, left axillary, right axillary or abdomen.

13. The method of claim 10, further comprising prompting a user upon expiration of the predetermined time limit.

14. The method of claim 10, wherein indication of the subject'"'"'s breathe from the capnography sensor is selectable from a graphical user interface.

15. The method of claim 10, wherein indication of the subject'"'"'s breath from the at least two electrodes is selectable from a graphical user interface.

16. The method of claim 10, wherein indication of the subject'"'"'s breath from the capnography sensor and from the at least two electrodes is selectable from a graphical user interface.

17. One or more computer readable media storing instructions that are executable by a processing device, and upon such execution cause the processing device to perform operations comprising:

receiving within a ventilation monitoring device an indication of a subject'"'"'s breath from at least one of a capnography sensor or at least two electrodes configured with the ventilation monitoring device to measure a transthoracic impedance of the subject; and

receiving within the ventilation monitoring device an indication of a positive result of an auscultation,

wherein receiving the indication of the positive result of the auscultation occurs within a predetermined time limit.

18. The computer readable media of claim 17, wherein a graphical user interface is configured to receive the at least one indication of a positive result of an auscultation.

19. The computer readable media of claim 17, wherein the indication of the positive result is related to an auscultation of a left lung, right lung, left axillary, right axillary or abdomen.

20. The computer readable media of claim 17, further storing instructions that are executable by the processing device, and upon such execution cause the processing device to perform operations comprising prompting a user upon expiration of the predetermined time limit.

21. The computer readable media of claim 17, wherein indication of the subject'"'"'s breath from the capnography sensor is selectable from a graphical user interface.

22. The computer readable media of claim 17, wherein indication of the subject'"'"'s breath from the at least two electrodes is selectable from a graphical user interface.

23. The computer readable media of claim 17, wherein indication of the subject'"'"'s breath from the capnography sensor and from the at least two electrodes is selectable from a graphical user interface.

24. The computer readable media of claim 17, further storing instructions that are executable by the processing device, and upon such execution cause the processing device to perform operations comprising electrocardiogram (ECG) monitoring of the subject.

25. The computer readable media of claim 17, further storing instructions that are executable by the processing device, and upon such execution cause the processing device to perform operations comprising initiating defibrillation the subject.
