IQ-CPR Meter for Chest Compression Monitoring During Simulated Cardiopulmonary Resuscitation; a Comparative Study

Adequate chest compression is crucial for cardiopulmonary resuscitation (CPR). There are sev-eral chest compression monitoring devices with different costs. This study aimed to evaluate the agreementrate of Improved Quality of Cardiopulmonary Resuscitation meter (IQ-CPR meter) and automated external de-fibrillator (AED) in chest compression quality monitoring.

In this comparative study, participantswere instructed to perform chest compression on the CPR manikins with the set rate of 110 times/minute fortwo minutes. The CPR manikins had two monitors: AED (R series®, Zoll company) and IQ-CPR meter. AEDshowed the depth and speed of chest compression on the screen, while IQ-CPR meter showed the depth of eachchest compression by color light for quality of chest compression depth. Video-based analysis was used to com-pare the chest compression quality monitoring between the 2 devices.

There were 27 participants inthe study with a mean age and body mass index (standard deviation; SD) of 26.00 (5.65) years, and 22.93 (3.62)kg/m2(70.37% male). The median (1stto 3r dquartile range) of chest compression experience was 3 (1.00-6.50)years. The mean (SD) of chest compression rate was 107 (5.29) times/minute. Based on Cohen’s Kappa correla-tion, agreement between the IQ-CPR meter and the AED was 66.54%.

The IQ-CPR meter had fairagreement with the computerized chest compression monitoring device with lower cost and simple, real timeaudiovisual feedback.
