Quality CPR matters
The trained rescuer knows that when faced with a sudden cardiac arrest patient, time and optimal therapy is critical for survival. Quality CPR combined with early defibrillation is essential to improve survival.1-3 Guidelines 4-5 provide direction on a number of parameters that define Quality CPR. However, the challenge for all emergency healthcare providers remains:
How can guidelines compliant CPR be delivered consistently throughout the whole chain of survival?
The 2010 Guidelines recommend compressing the patients’ chest at least 5 cm. Knowing when you have reached 5 cm is however difficult. As chest stiffness varies, some patients need much more compression force to meet the same guideline.This complicates matters even further. In fact, Tomlinson et al (2007) showed that patients’ chests require a compression force ranging from 10 - 55 kg force to reach the minimum compression depth.
How does CPRmeter™ work?
CPRmeter™ has two embedded sensors: one measuring acceleration and another measuring force. A sophisticated microprocessor continuously measures both of these parameters during each compression, and special algorithms convert the collected data into meaningful information.
The accelerometer measures the depth and rate of chest wall movement during each compression and converts it into distance travelled. The force sensor measures the force applied during CPR and is also used to detect whether the patient's chest is allowed to fully release between compressions. Feedback is provided if the responder is leaning during CPR. This helps the trained rescuer to deliver guidelines compliant chest compressions regardless of the chest stiffness of an individual patient.
Its rugged construction and excellent viewing angles, even in difficult environmental conditions, makes CPRmeter ideally suited to the chaos of the emergency situation.
