Abstract

A system for providing decision-assisted critical care to a patient in medical emergency situations in an out of hospital setting includes: a ventilator; an Automated External Defibrillator that includes primary electrocardiogram (ECG) sensors configured as chest pads that can be connected to the chest of the patient and to sense ECG and to deliver an electric shock to the patient'"'"'s heart; at least one secondary ECG sensor connected at a location other than the chest configured to sense ECG but not to deliver electric shock; and a controller configured, upon detection of shockable cardiac arrhythmias by at least one of said at least one secondary ECG sensors, to (a) instruct a caregiver to place the chest pads on the chest of the patient and to activate the AED, or (b) to automatically activate the AED if the chest pads are already in place on the chest of the patient.

Claims

1. A system for providing decision-assisted critical care to a patient in medical emergency situations in an out of hospital setting, said system comprising:

a ventilator comprising a pressure generator and a mask or endotracheal tube for delivering to the patient one of;

(a) oxygen, (b) air, or (c) oxygen and air;

an Automated External Defibrillator (AED) comprising a battery and primary electrocardiogram (ECG) sensors, said primary ECG sensors configured as chest pads that are configured to be connected to the chest of said patient and configured to both sense ECG and to deliver an electric shock to said patient'"'"'s heart;

at least one secondary ECG sensor, said secondary ECG sensors configured to sense ECG but not to deliver electric shock and configured to be connected to the body of said patient at a location other than the chest; and

a controller configured, upon detection of shockable cardiac arrhythmias by at least one of said at least one secondary ECG sensors, to (a) instruct a caregiver to place said chest pads on the chest of said patient and to activate said AED, or (b) to automatically activate said AED if said chest pads are already in place on the chest of said patient;

said system characterized in that, upon detection of shockable cardiac arrhythmia by at least one of said secondary ECG sensors, the AED is configured to;

(a) in case said primary ECG sensors sense and confirm the existence of cardiac shockable arrhythmia, said AED applies electric shock therapy according to standard protocol; and

(b) if said primary ECG sensors do not sense and confirm the existence of cardiac shockable arrhythmia, said AED does not apply an electric shock.

2. The system of claim 1, wherein the mask for delivering to the patient one of:

(a) oxygen, (b) air, or (c) oxygen and air is selected from;

a closed mask, an open mask with a reservoir, an open mask without a reservoir, and an endotracheal tube (ETT).

3. The system of claim 1, wherein the secondary ECG sensors are configured to be connected to the body of the patient at a location that is readily accessible, said location selected from:

a wrist, an ankle and a neck.

4. The system of claim 1 comprising at least one vital signs detector.

5. The system of claim 4, wherein the vital signs detectors are selected from:

Pulse Ox sensors, capnographs, non-invasive blood pressure sensors, and pressure sensor placed in the delivery means to verify the patient'"'"'s breathing.

6. The system of claim 4, wherein the controller is configured to adjust the operation of the ventilator according to readings from the at least one secondary ECG sensor and readings from at least one other vital signs detector.

7. The system of claim 1, wherein the controller is configured to adjust the operation of the ventilator according to readings from the at least one secondary ECG sensor.
