Aim Chest compression depth (CCD) decreases significantly when performing one‐handed chest compression (OHCC). We modified OHCC posture to increase CCD as follows: first, the axis of the compression hand was adjusted to the compression area; second, the opposite hand was wrapped around the elbow of the compression arm. This study compared modified OHCC with conventional OHCC for child cardiopulmonary resuscitation. Methods A total of 46 health‐care providers performed 2 min of continuous chest compression using conventional OHCC (trial 1) and modified OHCC (trial 2) in a random order on a 5‐year‐old‐sized child manikin lying on a bed. Chest compression parameters were assessed with an accelerometer and analysed by comparing the mean values of 30‐s segments. Results The average CCD decreased significantly in all segments in both trials (trial 1 (segments 1–4): 40.9 ± 5.6 mm, 39.4 ± 6.6 mm, 38.0 ± 6.9 mm, 36.7 ± 7.3 mm, P < 0.001; trial 2 (segments 1–4): 42.3 ± 5.4 mm, 41.2 ± 6.2 mm, 40.1 ± 6.8 mm, 39.0 ± 6.9 mm, P < 0.001). However, the average CCD in trial 2 was significantly greater in all segments than that in trial 1 (segments 1–4: P = 0.016; P = 0.009; P = 0.004; P = 0.001). The average chest compression rates were comparable in all segments in both trials. Conclusion By modifying OHCC posture, a deeper mean CCD could be maintained for 2 min than by using conventional OHCC.
