Highlights
- •Support surfaces variables, such as size, material, and density can influence the force performed during chest compression.
- •Backboard was not relevant for decreasing strength, regardless of the bed/stretch and mattress setups and the backboards' characteristics.
- •The dimensions and type of beds and mattresses, mainly, are related to higher resistance.
- •Intensive care environments present the most significant challenge in terms of surface characteristics that do not favor quality chest compression..
Abstract
Background: Support surfaces variables, such as size, material, and density, can determine
chest compression depth in cardiopulmonary resuscitation. Objective: to analyze the
force required to do a high-quality chest compression concerning different surfaces
in CPR. Method: This experimental study was developed using a Little Anne manikin
and a mechanical device to perform chest compressions. Nine sets of surfaces were
tested and compared to a control. Results: 230 experimental tests were done in sets
of bed or stretcher + mattress and presence or absence of different backboards. In
the control condition, the average force to reach 5 cm of depth was 42.14±0.97 (kgf).
Set 9, compatible with a narrow stretcher with a thin mattress, had the best surfaces
to reach recommended depth, with or without a backboard. All other sets required significantly
more force for high-quality chest compression. Regression analysis confirms that backboard
size is not significant for the force for high-quality chest compression. Conclusion:
There is an association of dimensions and types of beds or stretchers and mattresses
with a force increase. Type and dimensions of the backboard are not relevant for the
force required, regardless of the characteristics of the set of the bed or stretcher
and mattress.
