Patent Images
1. An inflatable vest fitting circumferentially around a person'"'"'s chest comprising:
- a belt adapted to be secured circumferentially around the chest, formed of an inextensible material, and having a length sufficient to at least extend circumferentially around the chest;
a bladder to fit in juxtaposition to at least a front portion of the chest and having a width to substantially cover a height of the chest, said bladder defined by an inner surface of the belt, a chest panel adjacent the inner surface and formed of an inextensible material, and at least one side panel formed of an inextensible material and having a first side edge attached to circumferential edges of the chest panel and a second side edge, opposite to the first, attached to the inner surface of the belt;
wherein the chest panel has an external surface adapted to be in substantial contact with the chest of the patient;
wherein the side panel lies substantially flat against the belt when the bladder is deflated, and extends inward towards the chest when the bladder is inflated.

Abstract
An improved vest design for cardiopulmonary resuscitation is disclosed. The vest includes an inflatable bladder capable of radial expansion to first conform to a patient'"'"'s chest dimensions and then to apply circumferential pressure. The improved vest design affords ease of placement on a patient without concern for how tightly the vest is initially applied. Also disclosed are various vest designs that reduce the amount of compressed air that must be used for each compression/decompression cycle of the vest. These improvements lower the energy consumption and make smaller and portable cardiopulmonary resuscitation systems possible.
