Introduction: In-hospital cardiac arrest has a poor prognosis and often occurs in patients lying in a hospital bed. A bed mattress is a soft compressible surface that may decrease cardiopulmonary resuscitation (CPR) quality. Often hospital CPR training is performed with a manikin on the floor.
Aim: To study CPR quality following realistic CPR training with a manikin in a bed compared with one on the floor.
Methods: We conducted a randomised controlled study. Healthcare professionals were randomised to CPR training with a manikin in a hospital bed or one on the floor. Data on CPR quality was collected from manikins. The primary outcome measure was chest compression depth.
Results: In total, 108 healthcare professionals (age: 40years, female: 94%) were included. The mean chest compression depth was 39mm (standard deviation (SD): 10), for the bed group compared with 38mm (SD: 9) for the floor group, p=0.49. A post hoc analysis showed that regardless of the training method, the participants who optimised their working position by jumping onto the bed or lowering the bed had a median chest compression depth of 39mm (25th-75th percentiles: 33-45) compared with 29mm (25th-75th percentiles: 23-41) for participants who did neither, p=0.04.
Conclusion: There was no significant difference in chest compression depth between healthcare professionals who trained CPR on a manikin in a hospital bed compared with one on the floor. Chest compression depth was too shallow in both groups. Irrespective of the training method, participants who optimised their working position performed deeper chest compressions.
