[External heart compression with the heel (author's transl)]
Insights
The leg-heel method for cardiopulmonary resuscitation (CPR) is not effective for lay rescuers, causing fatigue and pain. Current CPR techniques should be simplified to a single, universal method for better outcomes.
Area of Science:
- Emergency medicine
- Cardiopulmonary resuscitation techniques
- Resuscitation science
Context:
- External chest compressions are a standard during cardiopulmonary resuscitation (CPR).
- The conventional arm-hand method is widely used.
- The leg-heel method is proposed as an alternative technique.
Purpose:
- To evaluate the efficacy and user experience of the leg-heel method compared to the arm-hand method for external chest compressions.
- To assess compression characteristics (frequency, point, intensity, direction) and user-reported outcomes.
Summary:
- Both lay rescuers and paramedical personnel tested the leg-heel and arm-hand methods on a Resusci-Anne manikin.
- A significant majority (64%) found the leg-heel method ineffective due to early fatigue and leg pain.
- Failure rates were comparable, but the leg-heel method lacked proper sternal release, a critical factor in CPR effectiveness.
Impact:
- The leg-heel method presents significant disadvantages for lay rescuers, including user discomfort and potential ineffectiveness.
- Standardizing CPR training to a single, universally applicable method is recommended to avoid confusion and improve skill retention.
- Further research may be needed to refine or validate alternative CPR compression techniques.
Abstract:
External heart compression during cardiopulmonary resuscitation is an usual method. As an alternative to the arm-hand method the leg-heel method is proposed. Both methods were tested with a group of laymen and paramedical personnel at the Recording Resusci-Anne manequin. Criteria of evaluation were frequency, point, intensity and direction of heart pressure. 64 per cent of all test persons found the method of heel-compression to be of no value of the basis of personal experience. They showed early fatigue and complained of leg pain. The incidence of failure for both methods was comparable. Frequency and intensity of pressure showed no differences. The most important disadvantage appeared to be the lack of discharge of the sternum at the end of the phase of compression. Experience has shown that difficulties may arise from teaching several methods. Therefore the teaching of laymen should be restricted to one method only, usable universally. The restrictions of the leg-heel method are listed.
