Abstract

A method of applying electrotherapy to the heart of a patient includes positioning electrodes in communication with the heart of the patient; monitoring the patient'"'"'s heart to determine if its fibrillating; and providing a first signal with a current generator to the heart through the electrodes in response to an indication that the heart is fibrillating. The first stimulus signal reduces the amount of fibrillation.

Claims

1. A method of applying electrotherapy to the heart of a patient, comprising:

positioning electrodes in communication with the heart of the patient;

monitoring the patient'"'"'s heart to determine if its fibrillating; and

providing a first stimulus signal with a controlled direct current generator to the heart through the electrodes in response to an indication that the heart is fibrillating, the first stimulus signal reducing the amount of fibrillation, and wherein the first stimulus signal is a defibrillation signal with a voltage amplitude that is substantially constant over a specified period of time, and wherein the voltage amplitude is selected to be substantially constant between about 50 volts and 900 volts and the specified period of time for providing the first stimulus signal is selected between about 0.04 seconds and 10 seconds.

2. The method of claim 1, wherein the first stimulus signal includes a defibrillation stimulus signal or an over-drive pacing stimulus signal.

3. The method of claim 1, wherein the duration is proportional to a refractory period of the patient'"'"'s heart.

4. The method of claim 1, further including:

waiting a first amount of time;

monitoring the patient'"'"'s heart after the first amount of time to determine if its fibrillating; and

providing a second stimulus signal to the heart through the electrodes in response to an indication that the heart is fibrillating after the first amount of time, the second stimulus signal reducing the amount of fibrillation.

5. The method of claim 4, wherein the second stimulus signal includes a defibrillation signal or an over-drive pacing signal.

6. The method of claim 1, further including:

waiting a first amount of time;

monitoring the patient'"'"'s heart after the first amount of time to determine if its fibrillating; and

providing a pacing stimulus signal to the heart through the electrodes after the first amount of time in response to an indication that the heart is not fibrillating.

7. The method of claim 1, further including providing oxygen to the heart before providing the first signal.

8. The method of claim 1, further including ventilating the patient before providing the first signal.

9. The method of claim 1, further including providing a second signal with the current generator to the heart through the electrodes in response to an indication that a heart rate of the heart is below a predetermined value.

10. The method of claim 1, wherein the first signal includes a monophasic, biphasic, triphasic, and/or multiphasic waveform.

11. A system, comprising:

a ventilator having a breathing circuit for providing air-way breathing to a patient;

a chemical source in communication the ventilator;

an electrical contact positioned proximate to the chemical source, the electrical contact having a first charge capable of ionizing a chemical moving from the chemical source through the breathing circuit; and

a defibrillator for providing electrotherapy to the heart of the patient through electrodes, at least one of the electrodes having a second charge that is opposite the first charge of the electrical contact such that the electrically charged chemical is capable of moving in response to an electrical potential difference provided between the least one electrode and the contact.

12. The system of claim 11, further including a power source coupled to the electrical contact.

13. The system of claim 11, further including an audio system for providing audio sounds from the patient.

14. The system of claim 11, further comprising a mask in communication with the ventilator through the breathing circuit, and the electrical contact being positioned between expiratory and inspiratory tubes defined along the breathing circuit.

15. A system for providing life support to a patient, comprising:

a defibrillator for providing circulatory resuscitation to the patient;

a ventilator for providing respiratory resuscitation to the patient; and

a communication system being removably attached to either the defibrillator or the ventilator, the communication system having dual communication links, defined as primary communication and secondary communication links, each of the primary and secondary communication links having a transmitter and a receiver for sending and receiving voice and/or data information obtained from the defibrillator and/or ventilator to separate external communication systems, and the primary communication link having the means for controlling the secondary communication link such that the primary communication link in communication to a first external communication system can control the secondary communication link to initiate contact to a second external communication system.

16. The system of claim 15, wherein the defibrillator, ventilator, and communication system have separate circuits with conductive lines that permit the at least two of the defibrillator, ventilator, and communication system to be in communication with each other and are removably connectable between attached and detached positions.

17. The system of claim 15, further including a global positioning system for providing a location of the system.

18. The system of claim 15, further including a monitor for monitoring vital signs of the patient.

19. The system of claim 18, wherein the monitor displays the vital signs of the patient.

20. The system of claim 18, wherein the operation of the defibrillator, ventilator, and/or monitor is controllable in response to the vital signs being send to an external communication system.

21. The system of claim 15, wherein the communication system includes a phone.

22. The system of claim 15, further including an audio system which provides a sound in response to vital signs of the patient.

23. The system of claim 15, wherein the defibrillator and/or ventilator is controllable in response to one or more protocol procedures for providing life support to the patient and wherein the one or more protocol procedures are adjustable in response to a signal flowing between the communication system and the external communication system.

24. The system of claim 15, wherein the ventilator provides oxygen to the patient in response to an indication from the defibrillator that the patient is in asystole.
