A system applies cardiopulmonary resuscitation (CPR) to a recipient. An automated controller is provided together with a compression device which periodically applies a force to a recipient's thorax under control of the automated controller. A band is adapted to be placed around a portion of the torso of the recipient corresponding to the recipient's thorax. A driver mechanism shortens and lengthens the circumference of the band. By shortening the circumference of the band, radial forces are created acting on at least lateral and anterior portions of the thorax. A translating mechanism may be. provided for translating the radial forces to increase the concentration of anterior radial forces acting on the anterior portion of the thorax. The driver mechanism may comprise a tension device for applying a circumference tensile force to the band. The driver mechanism may comprise an electric motor, a pneumatic linear actuator, or a contracting mechanism defining certain portions of the circumference of the band. The contracting mechanism may comprise plural fluid-receiving cells linked together along the circumference of the band. The width of each of the fluid-receiving cells becomes smaller as each cell is filled with a fluid. This causes the contraction of the band and a resulting shortening of the circumference of the band.

The chest compression detector device comprises a signal transmitter operably positioned on the chest of the patient and adapted to broadcast a signal, and a signal receiver adapted to receive the signal. The chest compression detector device also comprises a processor, operably connected to the signal transmitter and the signal receiver. The processor repeatedly analyzes the signal received to determine from the signal a series of measurements of compression of the chest, and feedback is provided to the rescuer based on the series of measurements.

Embodiments of the present concept are directed to medical devices for use by a rescuer who is caring for a patient and includes a bottom device for use with a top device to measure the depth of Cardio Pulmonary Resuscitation (CPR) chest compressions delivered to the chest of a patient. The top device is intended for placement on the chest of the patient and has a top mechanism that is moveable up and down as the chest compressions are delivered to the patient. The bottom device includes a generally elongate member having a handle at one end and a bottom mechanism near the opposite end. The elongate member is structured to be placed under the patient during delivery of CPR. The top mechanism and the bottom mechanism cooperate to generate a value for a net depth of the compressions of the patient chest with reference to each other.

An indicating device assists rescue personnel in administering cardiopulmonary resuscitation (CPR). A transducer measures the pressure drop in a flow tube attached to the patient, and this pressure drop is converted into a flow rate and volume. Another transducer measures the pressure in the flow tube at a point near the patient, the measured pressure being essentially the same as, or related to, the intratracheal pressure. Indicator lights show either red or green or yellow, when the flow rate, and/or the intratracheal pressure, are within or outside of a preferred range. The desired ranges can be adjusted according to the weight of the patient. The device provides immediate guidance for rescue personnel, by indicating whether the volume of gas received by the patient is appropriate, and whether intratracheal pressure is below or above a potentially lethal level. It also provides a prompt light to indicate the desirable rate at which to administer respirations, a rate based upon the measured values of the exhaled volume and the intratracheal pressure.

An apparatus and method to be used in CPR to promote diastolic filling of the heart in cardiac arrest situations during external or internal cardiac compression. A rigid backboard provided with a tilting apparatus to incline the backboard to a desired degree. The backboard can be also provided with a tiltable segment for forward head flexion. The body of a patient victim of cardiac arrest is placed supine over the rigid backboard and the backboard is tilted by actuation of the tilting apparatus to a desired angle thus positioning the patient with feet up and chest down, so that the lower extremities are higher than the abdomen and tilted down toward the abdomen, and the abdomen higher than the chest and tilted down toward the chest. Likewise, being the head flexed forward in respect to the remainder of the body, the head is positioned higher than the heart, and tilted down toward the heart. As a result of such a positioning, the blood in the venous system of the lower extremities, of the abdomen and head will be draining down toward the heart by gravity improving diastolic filling and ultimately will improve cardiac output with internal or external cardiac compressions being carried out with the patient maintained in such position.
