What’s the difference between smartwatch and SimCPR® Trainer?
You can use your own smartwatch for CPR-feedback by simply downloading our
Smart CPR Trainer app. The smartwatch app
provides feedback through vibrations, icons and voice prompts.
The SimCPR® Trainer is a wristband using only a red + green LED for simple feedback. The wristband can be connected to a free smartphone app for extra feedback with depth and tempo scores.
How do I wear the smartwatch or SimCPR® Trainer for CPR-feedback?
You can use the smartwatch or wristband on your left- or right wrist. Preferably you wear it around the wrist of the hand that makes contact with the victim’s chest. This provides the most accurate results.
What does the smartwatch or SimCPR® Trainer measure?
The smartwatch and SimCPR® Trainer have a built-in accelerometer for registration of the chest compression movements.
Our accelerometer algorithm, accurately calculates the distance between compression and decompression (depth) and the tempo.
What feedback do I get from the SimCPR® Trainer?
As long as compression-decompression is
less than 5 cm/2 inches, the red LED will continue flashing. This means compressions are not deep enough and/or the recoil of the victim’s chest is not complete.
As soon as compression-decompression of the chest is more than 5 cm/2 inches, the green LED will flash (110/min).
When both depth and tempo are within the guidelines the green LED is continuously on.
This form of feedback improves the quality of CPR, even by healthcare professionals (Resuscitation 2019).
What feedback do I get from the smartwatch?
As long as compression-decompression is
less than 5 cm/2 inches, a weight-icon appears and you feel vibrations. This means compressions are not deep enough and/or the recoil of the victim’s chest is not complete.
When compressions are deep enough, but tempo is too slow or too fast, a turtle- or hare-icon appears in combination with vibrations.
When both depth and tempo are within the guidelines there are no vibration anymore and a green smiley appears. So no vibrations mean that your chest compressions are within the guidelines.
This form of feedback improves the quality of CPR, even by healthcare professionals (Resuscitation 2019).
Can an accelerometer measure leaning on the chest?
Indirectly it does. For example:
When the first responder compresses the chest 5,5 cm (2,2 inches) and keeps leaning 1 cm (0,4 inches), the device measures 4,5 cm (1,8 inches) compression/decompression. In this case the red LED keeps on flashing.
Before the first responder starts pushing harder, he/she has to check if the chest is fully released at the end of decompression.
When the chest is fully released, the device will measure 2,2 inches and the green LED will start flashing.
What's the battery life of the SimCPR® Trainer?
The battery of the SimCPR® Trainer will last for 6 year life in stand-by modus or 100 active hours of use.
It’s possible to change the 3V cell battery yourself.
Can I check the battery of the SimCPR® Trainer?
You can check the battery life fast and easy by turning the device on and turning it off again.
After turning it off (pressing the ON/OFF-button for 2 seconds or more) the green or red LED will light up short. When the green LED lights up, the battery life is still sufficient. If the red LED lights up you have to change the battery.
