An emergency medical kit for use, particularly by a non-professional, to render emergency medical treatment to a patient, includes: a pressurized-oxygen container within a housing; a face mask within the housing for application to the face of a patient requiring cardiopulmonary resuscitation; and a respiratory pump within the housing connected to the pressurized-oxygen container so as to be driven thereby to supply oxygen to the mask for inhalation by the patient, and to discharge the exhalations of the patient via the face mask to the atmosphere. The face mask includes an inflatable seal around its circumference engageable with the face of the patient receiving the mask for sealing the interior of the mask; a pressure sensor sensing the pressure in the inflatable seal; and an indicator for indicating whether the face mask is properly applied to the face of the patient.

A method of processing a raw acceleration signal, measured by an accelerometer-based compression monitor, to produce an accurate and precise estimated actual depth of chest compressions. The raw acceleration signal is filtered during integration and then a moving average of past starting points estimates the actual current starting point. An estimated actual peak of the compression is then determined in a similar fashion. The estimated actual starting point is subtracted from the estimated actual peak to calculate the estimated actual depth of chest compressions. In addition, one or more reference sensors (such as an ECG noise sensor) may be used to help establish the starting points of compressions. The reference sensors may be used, either alone or in combination with other signal processing techniques, to enhance the accuracy and precision of the estimated actual depth of compressions.

Devices, methods, and software implementing those methods for providing communicating external chest compression (ECC) devices and defibrillation (DF) devices, where the ECC and DF devices can be physically separate from each other. Both ECC and DF devices are able to operate autonomously, yet able to communicate with and cooperate with another device when present. Some ECC and DF devices are adapted to be physically and / or electrically coupled to each other. One ECC device includes a backboard, a chest compression member, a communication module, controller, and at least one sensor, electrode lead or electrode. One DF device includes a defibrillator module, a controller, and a communication module that can communicate with the ECC communication module. The communicating ECC and DF devices may deliver ECC, pacing, defibrillation, ventilation, and cooling therapies, and may deliver instructions to human assistants, in a coordinated and cooperative fashion.

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.

A gas-driven chest compression apparatus for cardiopulmonary resuscitation (CPR) comprises a flexible pneumatic actuator, capable of axial contraction when fed with a pressurized driving gas, and means for controlling the contraction thereof. Also disclosed are methods of providing chest compressions to a patient by means of a CPR apparatus comprising actuator(s) of this kind, and a corresponding use of the actuator.

The embodiments of the invention generally provide an external counterpulsation apparatus having an efficient cuff and bladder system. The embodiments generally allow effective treatment at lower pressures and a reduced total body surface area being compressed. An accurate and reliable combination of automatic and preset timing for inflation and deflation of the bladder system is used to simplify use of the apparatus.
