Furthermore expecting laypeople to undress the chest may increase bystander reluctance to perform cardiopulmonary resuscitation CPR . Both of these factors might conceivably decrease survival following cardiac arrest. Therefore the aim of this study was to examine if the presence or absence of clothes affected the quality of chest compressions during CPR on a simulator manikin. Methods Thirty laypeople and 18 firefighters were randomised to start CPR on the thorax of a manikin that was either clothed three layers or not. Data were obtained via recordings from the manikin and audio- and videorecordings. Measurements were maximum compression depth compression rate percentage of compressions with correct hand positioning percentage of compressions with complete release 10 mm and percentage of compressions of the correct depth range 40-50 mm . Laypeople were given a four-hour European Resuscitation Council standardised course in basic life support and tested immediately after. Firefighters were tested without additional training. Mock cardiac arrest scenarios consisted of three minutes of CPR separated by 15 minutes of rest. Results No significant differences were found between CPR performed on an undressed manikin compared to a dressed manikin for laypeople or firefighters. However undressing the manikin was associated with a mean delay in the initiation of chest compressions by laypeople of 23 seconds N 15 95 CI 19 27
