Abstract

Objectives

The hydraulic height control systems of hospital beds provide convenience and shock absorption. However, movements in a hydraulic bed may reduce the effectiveness of chest compressions. This study investigated the effects of hydraulic bed movement on chest compressions.

Materials and methods

Twenty-eight participants were recruited for this study. All participants performed chest compressions for 2 min on a manikin and three surfaces: the floor (Day 1), a firm plywood bed (Day 2), and a hydraulic bed (Day 3). We considered 28 participants of Day 1 as control and each 28 participants of Day 2 and Day 3 as study subjects. The compression rates, depths, and good compression ratios (> 5-cm compressions/all compressions) were compared between the three surfaces.

Results

When we compared the three surfaces, we did not detect a significant difference in the speed of chest compressions (p = 0.582). However, significantly lower values were observed on the hydraulic bed in terms of compression depth (p = 0.001) and the good compression ratio (p = 0.003) compared to floor compressions. When we compared the plywood and hydraulic beds, we did not detect significant differences in compression depth (p = 0.351) and the good compression ratio (p = 0.391).

Conclusions

These results indicate that the movements in our hydraulic bed were associated with a non-statistically significant trend towards lower-quality chest compressions.
