CPR simulator and trainer


The Fenton cardiopulmonary resuscitation simulator uses a PICAXE 08M to measure and monitor heart compression rate. The instrument operates in two modes; stand-alone and computer linked. Two simple sensors, a lever switch and capacitive humidity sensor, provide input to determine heart compression and respiration timing. The unit is lightweight and portable, augmenting the use of a ‘mini-Anne’ manikin (available from the St John Ambulance Service). In stand-alone mode, successful heart compressions can be heard as piezo beep sounds and also seen visually by LED indication. A LCD screen attached to the unit provides feedback about compression rate and prompts when respirations should be given, providing a significant improvement in a student’s ability to self-assess their skill at performing CPR. If linked to a computer, the RIGEL interface fulfills the function of the LCD and also provides a simulation of a heart beat trace and blood oxygenation levels. As someone who has received First Aid training, I find that the CPR simulator in its present form is extremely effective in its simplicity. The main difficulties I found with practicing my CPR technique were • ensuring that my compressions were deep enough to be effective on a potential patient and • ensuring that my compressions conformed to the recommended frequency of beats per minute All above information is for general reference only; always undertake CPR training from authorised medical experts such as St John.
