All operators must read the complete instructions for use for complete directions for use, indications, contraindications, warnings, precautions and potential adverse events before operating the LUCAS chest compression system.
“Always follow local and/or international guidelines for CPR when you use the LUCAS chest compression system.”
LUCAS 3 Instructions for Use; Chapter 1
Who can use the LUCAS device?
“Jolife recommends that the LUCAS Chest Compression System is only used by persons with medical skills such as: First responders, ambulance personnel, nurses, physicians or medical staff, who have:
undertaken a CPR course according to the resuscitation guidelines, e.g. American Heart Association, European Council of Resuscitation or equivalent,
AND received training in how to use the LUCAS device.”
LUCAS 3 Instructions for Use; Chapter 3.2
Who can be treated with LUCAS?
"LUCAS Chest Compression System is to
be used for performing external cardiac compressions on adult patients who have acute circulatory arrest defined as absence of spontaneous breathing and pulse, and loss of consciousness.
LUCAS must only be used in cases where chest compressions are likely to help the patient.
The LUCAS device is intended for use as an adjunct to manual CPR when effective manual CPR is not possible (e.g., during patient transport or extended CPR when fatigue may prohibit the delivery of effective/ consistent compressions to the victim, or when insufficient EMS personnel are available to provide effective CPR)." (US only)
LUCAS 3 Instructions for Use; Chapter 2.2
What are the contraindications?
“Do NOT use the LUCAS Chest Compression System in these cases:
If it is not possible to position the LUCAS device safely or correctly on the patient’s chest.
Too small patient: If the LUCAS device alerts with 3 fast signals when lowering the suction cup, and you cannot enter the PAUSE mode or ACTIVE mode.
Too large patient: If you cannot lock the upper part of the LUCAS device to the Back Plate without compressing the patient’s chest.
Always follow local and/or international guidelines for CPR when you use the LUCAS chest compression system.”
The majority of survivors are saved by early defibrillations. Remember to analyze ECG rhythm early and between every CPR cycle, and shock if indicated.
Uninterrupted high-quality CPR is related to good patient outcomes. Work in teams to minimize interruptions to manual CPR before and during LUCAS application.
Did you know that:
Well trained teams have shown it is possible to transition to LUCAS with an interruption to manual CPR of 7 seconds (median) in clinical use.1
What does the Instructions for Use say about manual CPR?
“When you have confirmed a cardiac arrest, immediately start manual cardiopulmonary resuscitation (CPR). Minimize interruptions to manual chest compressions during the preparation and application of the LUCAS chest compression system.”
LUCAS 3 Instructions for Use; Chapter 5.1
“The LUCAS device is intended for use as an adjunct to manual CPR when effective manual CPR is not possible (e.g., during patient transport or extended CPR when fatigue may prohibit the delivery of effective/consistent compressions to the victim, or when insufficient EMS personnel are available to provide effective CPR). (US only)”

LUCAS user interface
This mode is used when you want to adjust the position of the suction cup. When you push this key, you can manually move the suction cup up or down. To adjust the start position of the suction cup, manually push down the suction cup with two fingers onto the chest of the patient.
When you push this key, the compression mechanism temporarily stops and is locked in the start position. Use this function when you want to stop the device temporarily but still want to keep the start position of the suction cup.
When you push this key, the LUCAS device performs 30 chest compressions and then temporarily stops for 3 seconds. During the stop, the operator can perform 2 ventilations. After the stop the cycle starts again. An intermittent LED in combination with an audible signal sequence will alert the operator before each ventilation pause.
When you push this key, the LUCAS device performs continuous chest compressions. The green LED signal will blink 10 times per minute to alert for ventilation during ongoing compressions.
LUCAS application tips
Position the back plate
Aim at placing the back plate centrally behind the heart. The back plate should be high up at the patient’s armpits. The black bars of the back plate should align cross over the heart area and central chest compression point where the manual CPR provider has his/her hands.
Place patient’s arms straight out (i.e. crucifix position)
In large patients, move the patient’s arms up towards the head to get adipose tissue out of the way
Lift the patient’s upper body a small distance or roll the patient from side to side when placing the back plate
Coordinate the application to minimize interruptions to manual chest compressions
Position the back plate correctly from the start.
This helps facilitate a correct position of the suction cup.
The claw locks will lock onto the back plate with a "click". Pull up once to check the parts are attached.
To minimize interruptions to manual chest compressions, attach the support leg that is nearest to you first. Move the other support leg through the arms of the responder doing manual CPR. Ask him/her to assist with attaching the second support leg.
The claw locks will lock onto the back plate with a "click".
For how long will a fully charged battery operate?
45 minutes = typical operation time for fully charged battery
Three green LEDs: fully charged
Two green LEDs: 2/3 charged
One green LEDs: 1/3 charged
One intermittent yellow LED and a medium priority alarm signal: Less than 10 minutes remaining.
One intermittent red LED and high priority alarm signal: Battery empty.
Do you have to power off the device when changing batteries?
No, you do not have to power off the device when changing batteries, just push PAUSE. The device will remember the set start position and be ready to continue if you replace the batteries within 60 seconds.
Battery service life indication
"When the LED to the far right is yellow and not green, the battery has reached the end of its service life. Jolife recommends that you replace this battery with a new one."
LUCAS 3 Instructions for use; Chapter 2.7
Battery empty - high priority alarm
Battery charge is too low and compressions will stop. If you do not have a charged battery at hand, remove the stabilization strap and the LUCAS device, and resume manual chest compressions immediately.
Examples of other reasons for the high-priority alarm:
