Abstract: An apparatus and method for administering interposed abdominal counterpulsation cardiopulmonary resuscitation (IAC-CPR) to a patient. A generally rectangular board-like device having a chest compression pad and an abdominal compression pad depending from the underside is positioned on the torso of the patient and gripped at opposed ends by the hands of a person treating the patient. Force is applied alternately to each opposed end in a "see-saw" fashion to administer chest compressions in alternating sequence to abdominal compressions corresponding to the systole and diastole heart phases. The device may have a locator aperture through which the person treating the patient may manually or visually locate the breastbone of the patient to facilitate proper positioning and the pads may be adjustably positioned relative to one another to fit various size patients.
