Devices and methods for external chest compression
First Claim
1. A method for performing cardiopulmonary resuscitation of a patient suffering cardiac arrest and apnea, said method comprising:
- pressing an applicator body against the patient'"'"'s sternum to compress the patient'"'"'s chest, wherein sufficient pressure is applied to the sternum to compress the chest in the range from about 3.5 to 5 cm;
lifting the applicator to actively expand the patient'"'"'s chest wherein a lower surface of the applicator adheres to the patient'"'"'s chest; and
alternating the pressing and lifting steps at a rate in the range from about 80 to 100 repititions per minute until the patient'"'"'s heartbeat and respiration are restored.

Abstract
A method for performing cardiopulmonary resuscitation employs an applicator device having a body with an upper surface and a lower surface. The lower surface includes provisions for detachably securing to the patient'"'"'s chest, such as a vacuum cup or an adhesive layer. For manual resuscitation, the upper surface will include a strap or other means for securing a performer'"'"'s hand thereto. For automatic applications, a mechanical drive member will be secured to the upper surface. By alternately pressing and lifting on the applicator device, the patient'"'"'s chest can be compressed and expanded to improve induced ventilation and circulation.

8. A method for performing cardiopulmonary resuscitation of a patient suffering cardiac arrest and apnea, said method comprising:
-
compressing the patient'"'"'s chest by manually pressing on an upper surface of a flexible cup having a hollow interior, where a lower lip of the cup is disposed against the patient'"'"'s sternum resulting in a vacuum, wherein the chest is compressed sufficiently to induce blood circulation from the chest; actively expanding the patient'"'"'s chest by manually lifting on the upper surface of the flexible cup, wherein the chest is raised by the vacuum to further induce blood circulation and ventilation; and alternating the compressing and expanding steps according to a preselected rhythm, wherein each compressing step is followed by the expanding step. - View Dependent Claims (9, 10, 11, 12, 13, 14)

17. A method for simultaneously resuscitating and monitoring electrocardiographic activity of a patient suffering cardiac arrest, said method comprising:
-
pressing an applicator body against the patient'"'"'s chest at a location over the sternum to compress the chest; lifting the applicator to actively expand the patient'"'"'s chest, wherein a lower surface of the applicator adheres to the chest at said location over the sternum; detecting the patient'"'"'s electrocardiographic pattern through an electrode in the lower surface of the applicator; and alternating the pressing and lifting steps so that each pressing step will last in the range from about 0.2 to 0.7 seconds and each lifting step will last in the range from about 0.2 to 0.7 seconds until the patient'"'"'s heartbeat and respiration are restored. - View Dependent Claims (18, 19, 20, 21, 22, 23)
