Abstract

A medical ventilation monitoring system includes a patient ventilation unit defining an airflow path, the unit arranged so that when the unit is applied to a patient, the airflow path is in fluid communication with the patient's airway; an airflow sensor in the air flow path positioned to sense the presence of ventilation airflow to or from the patient; and a wireless transceiver arranged to receive data that is generated by a portable medical device, and to use the data to provide feedback to a rescuer regarding proper administration of ventilation.

First claim

What is claimed is:

1. A medical ventilation monitoring system, comprising:
a patient ventilation unit defining an airflow path, the unit arranged so that when the unit is applied to a patient, the airflow path is in fluid communication with the patient's airway, the patient ventilation unit including:
an airflow sensor positioned to sense the presence of ventilation airflow to or from the patient, and
a wireless transceiver; and

a portable computing device separate from the ventilation unit and arranged to communicate with the wireless transceiver, the portable computing device configured to:
provide an initial treatment protocol for providing care to the patient, the initial treatment protocol being executed includes applying ventilation at an initial ventilation rate and at an initial ventilation volume,
receive data regarding a current condition of the patient from the wireless transceiver and information from a remote medical system, and
determine an updated treatment protocol, the updated treatment protocol being executed includes applying ventilation at an updated ventilation volume different from the initial ventilation volume, or at an updated ventilation rate different from the initial ventilation rate, the updated treatment protocol being based at least in part on information from the airflow sensor and the information from the remote medical system.

2. The system of claim 1 , wherein the portable computing device is further configured to provide information for implementing the updated treatment protocol.

3. The system of claim 2 , wherein the portable computing device is configured to provide information for implementing the updated treatment protocol by transmitting data to the patient ventilation unit.

4. The system of claim 2 , wherein the portable computing device is configured to provide information for implementing the updated treatment protocol to a rescuer.

5. The system of claim 1 , wherein the patient ventilation unit comprises a mask that seals to and fits over a lower portion of the patient's face.

6. The system of claim 5 , wherein the patient ventilation unit further comprises a flexible bag connected to provide ventilation air through the air flow path.

7. The system of claim 1 , wherein the airflow sensor comprises a differential pressure sensor.

8. The system of claim 1 , wherein the wireless transmitter comprises a Bluetooth wireless transmitter.

9. The system of claim 1 , further comprising a defibrillator having a wireless transceiver configured to communicate with the wireless transmitter so as to provide, feedback to a rescuer in the vicinity of the wireless transmitter.

10. The system of claim 9 , wherein the feedback comprises feedback that communicates to the rescuer an appropriate rate for providing ventilation to the patient.

11. The system of claim 9 , wherein the portable computing device is further configured to receive inputs about a patient encounter from a medical caregiver, and programmed to generate a treatment regimen and to transmit data for implementing the treatment regimen.

12. The system of claim 11 , wherein the portable computing device is further programmed to transmit the data for implementing the treatment regimen to the patient ventilation unit.

13. The system of claim 11 , wherein the portable computing device is further programmed to transmit a first portion of the data for implementing the treatment regimen to the patient ventilation unit, and a second portion of the data for implementing the treatment regimen to the defibrillator.

14. The system of claim 1 , wherein the portable computing device is configured to receive input regarding a current condition of the patient, and to provide feedback to a rescuer based on one or more parameters that reflect the current condition of the patient.

15. The system of claim 14 , wherein the portable computing device is programmed to receive input regarding a current condition of a patient by posing one or more questions to the rescuer about the patient, and to use answers to the one or more questions to determine an appropriate treatment regimen for the patient.

16. The system of claim 1 , wherein the portable computing device is further programmed and arranged to upload information about the patient wirelessly to a central server system for sharing the uploaded information to caregivers at a central medical facility.

17. The system of claim 1 , further comprising a visual feedback mechanism for providing information to a rescuer regarding delivery of ventilation comprising a plurality of lights arranged to indicate, based on which lights of the plurality of lights are activated, whether excessive ventilation, too little ventilation, or an appropriate amount of ventilation is being provided to the victim.

18. The system of claim 1 , further comprising a visual feedback mechanism for providing information to a rescuer regarding delivery of ventilation comprising a ventilation timer providing information about respiratory rate.

19. The system of claim 1 , further comprising a visual feedback mechanism for providing information to a rescuer regarding delivery of ventilation comprising a ventilation timer providing information about elapsed time between ventilation events.

20. A ventilation monitoring method for a patient, the method comprising:
applying ventilation to a patient at an initial ventilation rate and at an initial ventilation volume;
receiving at a portable computing device information about the ventilation of the patient received from a transmitter connected to an airflow sensor in an artificial ventilation unit placed in or near an airway of the patient;
receiving, at the portable computing device, information from a remote medical system;
generating with the portable computing device an updated treatment approach for the patient, the updated treatment approach being executed includes applying ventilation at an updated ventilation volume different from the initial ventilation volume, or at an updated ventilation rate different from the initial ventilation rate, the updated ventilation rate and the updated ventilation volume being based at least in part on the information about ventilation of the patient and the information from the remote medical system; and
providing feedback to a caregiver of the patient that incorporates the updated treatment approach.

21. The method of claim 20 , wherein providing feedback comprises transmitting ventilation rate information to the artificial ventilation unit.

22. The method of claim 21 , further comprising generating an audible or visual feedback signal on the artificial ventilation unit that indicates to a caregiver an appropriate ventilation rate for the patient.

23. The method of claim 21 , further comprising displaying a visual feedback mechanism that provides information about respiratory rate.

24. The method of claim 21 , further comprising displaying a visual feedback mechanism that provides information about elapsed time between ventilation events.

25. The method of claim 20 , further comprising receiving at the portable computing device information about chest compressions performed on the patient from a sensor located near the patient's chest and providing feedback to a caregiver of the patient that incorporates the treatment approach.

26. The method of claim 20 , further comprising wirelessly uploading, from the portable computing de
