Acoustic sensor platform method and apparatus for pain mitigation, apnea detection, aspiration detection and patient communication in anesthesia patients

1. An acoustic sensor platform for anesthesia patients comprising:

a) An acoustic sensor configured to be coupled to one of a nasal cannula or face mask of an anesthesia patient;

b) A processer coupled to the acoustic sensor and configured to

i) Detect patient speech and isolate and amplify the patient speech;

ii) Detect at least one of a breathing rate of the patient or aspiration of the patient;

c) An audio visual display coupled to the processor and providing an audio and/or visual display of the isolated and amplified speech of the patient, and displaying results for at least one of the breathing rate of the patient or the aspiration of the patient.

2. The acoustic sensor platform for anesthesia patients according to claim 1 wherein the detecting patient speech and isolating and amplifying the patient speech includes providing real time dictation of the words of the patient to be displayed on the audio visual display.

3. The acoustic sensor platform for anesthesia patients according to claim 2 wherein detecting patient speech and isolating and amplifying the patient speech includes noise cancellation to remove undesired background noise to isolate a voice signal of the patient and amplify this patient voice signal for an operator which isolated and amplified patient voice signal is transmitted over the audio visual display.

4. The acoustic sensor platform for anesthesia patients according to claim 3 wherein an audible and dictated textual record of the isolated and amplified patient speech during a proceeding is automatically created and stored.

5. The acoustic sensor platform for anesthesia patients according to claim 1 wherein the detecting patient speech and isolating and amplifying the patient speech includes noise cancellation to remove undesired background noise to isolate a voice signal of the patient and amplify this patient voice signal for an operator which isolated and amplified patient voice signal is transmitted over the audio visual display.

6. The acoustic sensor platform for anesthesia patients according to claim 1 wherein an audible and/or dictated textual record of the isolated and amplified patient speech during a proceeding is automatically created and stored.

7. The acoustic sensor platform for anesthesia patients according to claim 1 wherein the platform detects the breathing rate of the patient.

8. The acoustic sensor platform for anesthesia patients according to claim 7 wherein the detection of the breathing rate includes apneic detection of an apneic episode.

9. The acoustic sensor platform for anesthesia patients according to claim 8 wherein the audio visual display visually displays results of the breathing rate/apneic episode detection in real time.

10. The acoustic sensor platform for anesthesia patients according to claim 9 wherein the audio visual display alerts an operator of dangerous or significant conditions of the patients breathing rate.

11. The acoustic sensor platform for anesthesia patients according to claim 9 wherein a record of the detected breathing rate during a proceeding is automatically created and stored.

12. The acoustic sensor platform for anesthesia patients according to claim 1 wherein the platform detects the aspiration of the patient wherein the acoustic sensor picks up audible signals indicative of regurgitation/aspiration of the patient.

13. The acoustic sensor platform for anesthesia patients according to claim 12 wherein the audio visual display alerts an operator of dangerous or significant conditions related to regurgitation/aspiration of the patient.

14. The acoustic sensor platform for anesthesia patients according to claim 12 wherein a record of the detected patient aspiration during a proceeding is automatically created and stored.

15. The acoustic sensor platform for anesthesia patients according to claim 12 wherein the platform also detects the breathing rate of the patient and wherein the detection of the breathing rate includes apneic detection of an apneic episode.

16. The acoustic sensor platform for anesthesia patients according to claim 15 wherein the audio visual display alerts the operator of dangerous or significant conditions related to the breathing rate and the regurgitation/aspiration of the patient.

17. The acoustic sensor platform for anesthesia patients according to claim 12 wherein a record of the detected breathing rate and the patient aspiration during a proceeding is automatically created and stored.

18. The acoustic sensor platform for anesthesia patients according to claim 1 further including additional physiologic sensors on the platform and coupled to the processor.

19. A method of Pain Mitigation, Apnea Detection, Aspiration Detection and Patient Communication in Anesthesia Patients comprising the steps of:

a) Coupling an acoustic sensor to one of a nasal cannula or face mask of an anesthesia patient;

b) Detecting patient speech and isolate and amplify the patient speech via a processer coupled to the acoustic sensor;

c) Detecting at least one of a breathing rate of the patient or aspiration of the patient via a processer coupled to the acoustic sensor;

d) providing an audio and/or visual display of the isolated and amplified speech of the patient on an audio visual display coupled to the processor; and

e) displaying results for at least one of the breathing rate of the patient or the aspiration of the patient on the audio visual display.
