Abstract

A medical ventilation monitoring system is provided. The system includes: a patient ventilation unit defining an airflow path, and 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 includes: an airflow sensor positioned to sense the presence of ventilation airflow to or from the patient and a communication link. The system also includes at least one processor arranged to communicate with the ventilation unit by the communication link. The at least one processor is configured to: provide an initial treatment protocol for providing care to the patient, receive data regarding a current condition of the patient from the ventilation unit, and determine an updated treatment protocol. The updated treatment protocol includes applying ventilation at an updated ventilation volume or at an updated ventilation rate based on information from the airflow sensor.

Claims

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 communication link; and

at least one processor arranged to communicate with the ventilation unit by the communication link, the at least one processor configured to;

provide an initial treatment protocol for providing care to the patient, wherein the initial treatment protocol being executed includes applying ventilation at an initial ventilation rate and at an initial ventilation volume,

receive information from the airflow sensor

determine an updated treatment protocol, wherein 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 the information from the airflow sensor; and

provide feedback to a rescuer regarding proper administration of ventilation to the patient based, at least in part, on the information from the airflow sensor.

2. The system of claim 1, further comprising a portable medical device electrically coupled to the at least one processor.

3. The system of claim 2, wherein the portable medical device comprises a defibrillator.

4. The system of claim 3, wherein the at least one processor is configured to communicate information from the defibrillator to the patient ventilation unit, so as to provide the feedback to the rescuer in the vicinity of the patient ventilation unit.

5. The system of claim 4, wherein the feedback comprises feedback that communicates to the rescuer an appropriate rate for providing ventilation to the patient.

6. The system of claim 1, wherein the at least one processor is separate from the patient ventilation unit.

7. The system of claim 6, wherein the ventilation unit is in wired communication with the at least one processor.

8. The system of claim 1, wherein the at least one processor is further configured to receive information from a remote medical system, and wherein the updated treatment protocol is based, at least in part, on the information received from the remote medical system.

9. The system of claim 8, wherein the at least one processor is configured to communicate wirelessly with the remote medical system.

10. The system of claim 1, wherein the communication link comprises a wired or wireless transmitter.

11. 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.

12. The system of claim 11, wherein the patient ventilation unit further comprises a flexible bag connected to provide ventilation air through the air flow path.

13. The system of claim 1, further comprising a portable computing device electronically coupled to the at least one processor.

14. The system of claim 13, wherein the portable computing device is configured to receive inputs about a patient encounter from a medical caregiver, and wherein the at least one processor is configured to generate the updated treatment protocol based, in part, on the received inputs.

15. 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 communication link; and

at least one portable computing device arranged to communicate with the communication link, the portable computing device configured to

receive information from the airflow sensor from the communication link, and

provide feedback to a rescuer regarding proper administration of ventilation to the patient based, at least in part, on the information from the airflow sensor.

16. The system of claim 15, wherein the at least one portable computing device is further configured to receive information from a remote medical system, and wherein the feedback to the rescuer regarding proper administration of ventilation to the patient is based, at least in part, on the received information from the remote medical system.

17. The system of claim 15, wherein the at least one portable computing device comprises a defibrillator.

18. The system of claim 15, further comprising a defibrillator having a wired or wireless transceiver configured to communicate with the at least one portable computing device, and wherein the feedback to the rescuer regarding proper administration of ventilation to the patient is based, at least in part, on information received from the defibrillator.

19. The system of claim 15, wherein the portable computing device is further configured to receive inputs about a patient encounter from a medical caregiver and generate a treatment protocol based on the received inputs, and wherein providing feedback to the rescuer comprises assisting the rescuer in performing aspects of the treatment protocol.

20. The system of claim 19, wherein the portable computing device is further configured to transmit data for implementing the treatment protocol to the patient ventilation unit.
