ABSTRACT
AIM: To analyse the caregivers' physical, anthropometrical and educational characteristics associated with adequate chest compression and full chest recoil during cardiopulmonary resuscitation (CPR). METHODS: An observational prospective research study was conducted. Emergency and critical care health professionals and students performed two minutes of chest compressions on a dummy. Depth and residual leaning after the compressions were assessed and their association with several variables (physical, anthropometrical, and educational) was analysed using logistic regression models. RESULTS: Two hundred thirty-eight volunteers participated. Previous experience of the rescuer in less than six CPRs (OR = 3.03; 95% CI 1.2-7.63) was related to a higher probability of not achieving an adequate depth of compressions. Greater height (OR: .93; 95% CI .87-.99) and grip strength (OR: .94; 95% CI .89-.99) were associated with correct performance of chest compression. We did not find any characteristic related to chest recoil. CONCLUSIONS: The caregiver's previous experience with CPR was the strongest factor associated with adequate performance of chest compressions. To a lesser extent, the professional's height and upper body muscle strength also have an influence. No factors associated with the adequacy of full chest recoil were identified.

Objetivos: Analizar las características físicas, antropométricas y formativas de los reanimadores asociadas a la correcta compresión y reexpansión torácica durante la reanimación cardiopulmonar. Metodología: Estudio observacional prospectivo. Profesionales y estudiantes sanitarios de urgencias y cuidados críticos realizaron 2min de compresiones torácicas sobre un maniquí. Se evaluó la profundidad y la presión residual tras las compresiones, y se estudió su asociación a diferentes variables (físicas, antropométricas y formativas) mediante la creación de modelos de regresión logística. Resultados: Participaron 238 voluntarios. Que el reanimador tuviese una experiencia previa en menos de 6 reanimaciones cardiopulmonares (OR: 3,03; IC 95%: 1,2-7,63) se asoció a una mayor probabilidad de no lograr una profundidad adecuada en las compresiones. Una mayor estatura (OR: 0,93; IC 95%: 0,87-0,99) y fuerza de aprehensión (OR: 0,94; IC 95%: 0,89-0,99) fueron condiciones que actuaron como factores predisponentes a la ejecución de una técnica correcta. Ninguna característica se asoció a la adecuación de la reexpansión torácica. Conclusiones: La experiencia previa del reanimador es el factor más fuertemente asociado a la correcta ejecución de las compresiones torácicas. En menor medida, también influye la estatura y la fuerza del tren superior del profesional. No se han identificado factores asociados a la adecuación de la reexpansión torácica tras las compresiones.(AU)
