Abstract
Medical radar devices, including ultra-wideband (UWB) devices, for use in assisting and/or guiding cardiopulmonary resuscitation (CPR) by indicating one or more of: compression depth, compression frequency, and a return to spontaneous circulation. The devices and methods described herein may use reflected energy applied to a patient's chest to determine cardiac motion and/or chest compression and provide feedback to the person applying the CPR. In some variations the device is incorporated as a part of another resuscitation device, such as a defibrillator or automatic compression device.
Claims28
A device for determining the return of spontaneous circulation (ROSC) when applying cardiopulmonary resuscitation (CPR), the device comprising:
- a surface configured to be placed against a patient's chest;
- an energy emitter and energy detector configured to emit energy from the surface into the patient;
- a processor coupled to the energy detector and energy emitter and configured to evaluate blood pressure from energy returning from the patient after being emitted into the patient;
- and
- an output configured to indicate the ROSC based on the blood pressure evaluation of the processor.
A device for determining the return of spontaneous circulation (ROSC) when applying cardiopulmonary resuscitation (CPR), the device comprising:
- a surface configured to be placed against a patient's chest;
- an energy emitter and energy detector configured to emit energy from the surface into the patient;
- a processor coupled to the energy detector and energy emitter and configured to evaluate blood pressure from energy returning from the patient after being emitted into the patient;
- and
- an output configured to indicate the ROSC and to guide compression based on the processor's evaluation of energy returning from the patient after being emitted into the patient.
A device for determining the return of spontaneous circulation (ROSC) when applying cardiopulmonary resuscitation (CPR), the device comprising:
- an ultra-wideband (UWB) transmitter and receiver configured to emit energy into a patient and to receive reflected energy;
- a processor coupled to the UWB transmitter and receiver detector and energy emitter and configured to evaluate blood pressure based on the time-of-flight of the reflected energy returning from the patient;
- and
- an output configured to indicate the ROSC and to guide compression based on the processor's evaluation of the time-of-flight of the reflected energy.
A method of determining the return of spontaneous circulation (ROSC) when applying cardiopulmonary resuscitation (CPR), the method comprising:
- placing a device against the patient's chest, wherein the device comprises an energy emitter and energy detector configured to emit energy from the surface into the patient and a processor coupled to the energy detector and energy emitter;
- performing CPR on the patient;
- emitting energy from the device into the patient's chest;
- detecting energy reflected from the patient's chest;
- evaluating the patient's blood pressure from the energy reflected from the patient's chest;
- and
- indicating based on the evaluated blood pressure if the patient has returned to spontaneous circulation.
