A pneumatic compression pump is a basic component of intermittent pneumatic compression (IPC), a widely used technique that involves attaching an electrical air compression pump to an inflatable plastic garment that is placed over the affected limb.
When performing chest compressions, proper hand placement is very important. To locate the correct hand position place two fingers at the sternum (the spot where the lower ribs meet) then put the heel of your other hand next to your fingers (Figure 1). Place one hand on top of the other and interlace the fingers (Figure 2). Lock your elbows and using your body's weight, compress the victimâs chest. The depth of compressions should be approximately 1Â½ to 2 inches - remember: 2 hands, 2 inches (Figure 3). If you feel or hear slight cracking sound, you may be pressing too hard. Do not become alarmed and do not stop your rescue efforts!
