ZOLL ResQPUMP Mode D'emploi page 4

standard CPR via the device's piston. The handle includes a force gauge that displays the forces exerted during
both chest compression and decompression (chest wall recoil).
The ResQPUMP has a battery-powered metronome integrated into the handle to guide the rescuer in the
appropriate compression/decompression rate. The metronome emits two-tone signals of the same duration, one
low and one high pitch tone. The signal (set at 80/minute) guides the rescuer to compress and decompress at
the appropriate rate and for equal amounts of time (50% duty cycle). This slightly slower rate allows for extra
filling time for preload.
5. INSTRUCTIONS FOR USE
Proper use of the ResQPUMP is shown in Figures b through h.
5.1 Device Positioning
The ResQPUMP's compression point is the same as for standard manual CPR (Figure c). Position the suction
cup in the middle of the sternum (clothing removed) between the nipples. Make sure that the edge of the suction
cup does not extend below the xiphoid process, as this could result in inadequate suction and/or rib injury.
5.2 Rescuer Positioning
Kneel close to the patient's side. Shorter rescuers may find it beneficial to be slightly elevated by kneeling on
padding. If the patient is in bed (with hard surface under torso), it will be necessary to stand on a platform of
sufficient height. Grasp the ResQPUMP's handle with both hands, placing the heels of the hands near the gauge
with wrists slightly bent (Figure d).
5.3 Compressions
Compress the chest to the recommended depth (e.g. 2" or 5 cm), observe the force gauge and note the force
required to achieve that depth, and then use that force target as a guide. The amount of force required will vary
according to how compliant the chest is. Compress with shoulders directly over the sternum, with arms straight
(Figure e). Use the large thigh muscles to compress, bending at the waist. Compress at a rate of 80/min and
use the metronome to guide the compression rate. Start and stop the metronome by pressing the red button on
the force gauge (Figure f). Compress the chest on one tone and lift on the other tone.
The red arrow tip indicates the force being applied (Figure f). The approximate amount of force required to
compress the chest two inches (5 cm) is as follows:
• 30 kg of force: soft/supple chest
• 30 - 40 kg of force: chest of medium/average compliance (Figure f)
• 50 kg of force: stiff/rigid chest
Once it has been determined how much force is required to compress the chest to the appropriate depth, use
that amount of force as a guide for continued compressions.
5.4 Decompressions
To provide active decompression, keep arms straight and use the large muscles in the thighs to lift, bending
at the waist (Figure g). Attempt to decompress (lift) the chest until the tip of the red arrow on the force gauge
registers -10 kg of force (Figure h). This amount of upward force must be exerted to fully achieve the benefits
of active decompression. Closely monitor the force gauge and suction cup seal during use. If the suction cup
dislodges, reposition it with the next compression; then, on the next decompression, lift until just before the
suction cup releases but do not exceed -10 kg of lift. Use a 50% duty cycle, spending equal time compressing
and decompressing.
5.5 Suction Cup Removal
Lift up an edge of the suction cup lip to release the vacuum under the cup. This will free the cup from the
patient's chest.
5.6 Other
1. Rotate ACD-CPR duties every two minutes (or more often) to avoid fatigue.
2. If the patient has a return of spontaneous circulation (ROSC), use of the ResQPUMP should be discontinued.
If the patient re-arrests, resume ACD-CPR again immediately.
3. If suction difficulties occur, adjust the angle of the ResQPUMP on the chest to obtain an adequate seal. If you
are not able to maintain suction with 10 kg of lift, then lift with less force on the next decompression. It may
be necessary to shave hair from the middle of the chest to achieve good suction. NOTE: If suction difficulties
persist, the ResQPUMP can still be used for compressions (with the metronome disabled) without causing
additional harm to the patient, as long as it does not distract from CPR quality.
