Definitions

  • the invention relates generally to cardio-pulmonary resuscitation ("CPR") coaching and training devices, and more particularly, to a device that calculates a depth for a chest compression and provides tactile feedback to a rescuer when the compression depth is sufficient.
  • CPR cardio-pulmonary resuscitation
  • Cardiac arrest is a life-threatening medical condition in which the patient's heart fails to provide blood flow to support life.
  • CPR can be administered to a patient experiencing cardiac arrest to cause blood to flow in the patient.
  • a rescuer administers CPR by compressing the patient's chest interspersed with blowing into the patient's mouth to fill the lungs with oxygen.
  • CPR can be combined with other forms of therapy as well, such as defibrillation therapy.
  • the electrical activity of the heart may be disorganized (ventricular fibrillation, "VF"), too rapid (ventricular tachycardia, "VT"), absent (asystole), or organized at a normal or slow heart rate without producing blood flow (pulseless electrical activity).
  • a defibrillation shock delivered to a patient suffering from VF or VT can stop the unsynchronized or rapid electrical activity and allow a normal sinus rhythm to return. Between the times of delivery of defibrillation shocks to a patient, CPR is administered to promote blood flow.
  • the quality of the CPR is directly related to the quality of the chest compressions, a part of which is determined by compression depth. That is, good chest compressions are generally those which depress the chest of an adult by four centimeters and about two and a half centimeters for a child.
  • compression depth is commonly measured and the information fed back to the participant. It is assumed that by practicing chest compressions on a manikin, the participant will be capable of repeating the same movement pattern on real human patients.
  • 2006/0019229 describes a device that emits a sound when the chest compression is performed with a force that exceeds a predetermined value.
  • the device optionally also emits a sound indicating the intended frequency of chest compressions for correct pacing.
  • U.S. Patent No. 6,306,107 describes a device that includes an accelerometer, a force activated switch, and a calculation unit.
  • the device is positioned on the patient's chest during CPR to register parameters such as depression distance, duration or rate of depressions during chest compression.
  • Visual feedback on the depth of the compressions is provided to the rescuer by light-emitting diodes ("LEDs") or both visual and audible feedback are provided by way of a display unit having a screen and loudspeaker.
  • LEDs light-emitting diodes
  • CPR coaching has also been integrated into a defibrillator as well.
  • U.S. Patent No. 6,125,299 U.S. Patent No. 6,351,671
  • the '299 and '671 patents both describe a force sensor which is placed on the patient' s chest and to which chest compressions are applied.
  • the force sensor is connected to a defibrillator which senses the applied force of the chest compressions and, using the defibrillator's audible prompts, coaches the rescuer to press "harder” or “softer” or “faster” or “slower.”
  • the '107 patent describes a compression pad with an accelerometer instead of a force sensor which senses the depth of the chest compressions rather than their force.
  • the approach described in the '107 patent is preferable as CPR guidelines are directed to the depth of compression rather than the applied force, which does not always correlate with compression depth due to different chest resistances to CPR compression.
  • conventional CPR coaching devices provide feedback to a rescuer in the form of visual and audible feedback.
  • visual and audible feedback may be difficult for the rescuer to perceive.
  • audible feedback may be drowned out by the ambient background noise. Consequently, the rescuer will not be able to hear the audible coaching prompts.
  • the device displaying the visual feedback can be obscured from the rescuer's view, such as when many people are present or the display device is awkwardly located relative to the rescuer.
  • the rescuer may be forced to look in a direction other than at the patient to observe the visual feedback, which can be distracting to the rescuer while trying to focus on administering chest compressions.
  • CPR coaching devices that provide visual feedback directly on the body of the device allow a rescuer to focus their vision in the same direction of the patient. However, providing the visual feedback directly on the body of the coaching device forces the rescuer to grasp the CPR coaching device in a manner which avoids covering the visual feedback with the rescuer's hands.
  • a CPR coaching device can be designed to have a portion of the body extend in manner that allows visual feedback to be observed even while the rescuer's hands are placed over the CPR coaching device. The extended portion, however, can make the CPR coaching device bulkier and more difficult to handle.
  • One aspect of the invention provides a system for assisting a rescuer administer
  • the system includes a device configured to be placed between the hands of the rescuer and the chest of the patient during administration of chest compressions.
  • the device measures acceleration during a chest compression and calculates a displacement during the chest compression. Based on the calculated displacement, the device provides tactile feedback to the rescuer at a displacement depth to indicate that the depth of the chest compression is sufficient.
  • the device includes a housing and an accelerometer that is configured to measure acceleration of the device and generate an output signal indicative of the measured acceleration.
  • a calculation circuit coupled to the accelerometer calculates a displacement for the CPR coaching device from the measured acceleration and a control circuit coupled to the calculation circuit compares the calculated displacement to a displacement range or threshold and generates an active control signal in response to the calculated displacement meeting and/or exceeding the displacement threshold and/or range.
  • the device further includes an actuator coupled to the control circuit to receive the control signal and fixed in the housing. The actuator is configured to generate a tactile sensation transmitted to the housing in response to the active control signal.

The sensation of the upper surface 120 deflecting serves as notice that the compression should be released and allow the chest to return to its normal position.
  • the deflection can be tailored to promote tactile sensation, such as the actuator 306 quickly releasing the upper surface 120 inwardly when the depth of the compression is sufficient.
  • the actuator 306 can comprise a snap-dome device with a quick, releasing sensation to provide an audible clicking sound when the compression depth is sufficient.
  • the snap-dome can deflect and produce a tactile clicking sensation simply in response to the compressive force of the rescuer during CPR or, alternatively, when the required compressive depth has been reached, a solenoid adjacent to the snap-dome can be commanded to strike or deflect the snap- dome to produce the tactile sensation.
  • the tactile feedback is provided by deflecting the upper surface 120 of the CPR coaching device 100 outwardly, such as by the actuator 306 providing a gentle poking or lifting sensation of the upper surface 120 that can be felt by the hands of the rescuer 220 when applying the chest compression.

  • the visual feedback of the CPR coaching device 400 is provided by an array of lights 404, such as light emitting diodes ("LEDs"), and a pacing meter 420.
  • a calculation and control unit included in the CPR coaching device 400 is operable to calculate displacement and generate an active CNTRL signal to trigger the tactile feedback, as previously discussed with reference to the calculation and control unit 304.
  • the calculation and control unit of the CPR coaching device 400 is further operable to analyze the calculated displacement to determine if the rescuer allows for sufficient release of a compression before applying a next chest compression.
  • the processor controls the array of lights 404 to indicate whether the compression is deep enough and whether the release is sufficient. For example, with the CPR coaching device 400 placed on the chest of the patient 210 and no pressure applied, segment 410 is illuminated indicating a fully released position. As the patient's chest is compressed by the rescuer 220, additional segments of the array of lights 404 are sequentially illuminated until segment 414 is illuminated to indicate that the compression is sufficiently deep. As the compression is released, and the patient's chest begins to return to its normal position, the segments sequentially switch off. Thus, if the chest compression is not sufficient, segment 414 is never illuminated, indicating that the chest compression needs to be deeper.
  • the tactile feedback can also be used to coach the proper release between chest compressions. For instance, tactile feedback of one sound or sensation can be delivered when compression reaches the proper depth or depth range, and another tactile sound or sensation can be delivered when the compression pressure is released as fully as necessary. The device will make a "click” sound and sensation when the proper depth is reached and a "clack” sound and sensation when the compression is released to the proper degree. A further alternative is to deliver a distinct sound or sensation if the chest is too deeply compressed. Thus, the rescuer is coached to deliver a repetitive sequence of "click” and "clack” sensations with each chest compression.
