RESUMEN

Objetivos:

1) Analizar las diferencias por sexo en el porcentaje medio de compresiones torácicas externas (CTE) correctas realizadas sobre maniquí por jóvenes universitarios durante 20 minutos por categorías de índice de masa corporal (IMC), capacidad cardiorrespiratoria (CCR) y fuerza muscular; 2) examinar la asociación del IMC y la forma física con la proporción de CTE correctas; y 3) establecer los puntos de corte óptimos de VO2max y fuerza muscular en brazos para realizar CTE correctas.

Método:

Estudio cuasi-experimental que incluyó 63 estudiantes universitarios. Se determinaron IMC, CCR y fuerza muscular manual. Tras formación previa, realizaron reanimación cardiopulmonar (RCP) en un maniquí durante 20 minutos.

Resultados:

Los porcentajes medios de CTE correctas y con profundidad adecuada fueron 77,8 (65,1-90,5) y 86,0 (71,7-94,3) en hombres y 41,2 (32,2-50,1) y 43,7 (24,6-52,9) en mujeres (p ≥ 0,001). Las diferencias por género desaparecieron controlando por edad, IMC, CCR y fuerza muscular. El porcentaje medio de CTE correctas fue significativamente mayor en participantes con normopeso/sobrepeso y CCR y fuerza muscular altas. El IMC, la CCR y la fuerza muscular fueron predictores de una adecuada profundidad de compresiones en los modelos de regresión lineal múltiple controlando por edad y sexo. En las curvas ROC, el área bajo la curva para predecir CTE correctas fue 0,862 para VO2 max y 0,872 para la fuerza muscular (puntos de corte de 44,45 ml/Kg/min y de 30,22 Kg respectivamente).

Conclusiones:

El género, las características antropométricas y la forma física influyen en la realización de CTE correctas. Ello sugiere que una adecuada forma física aumentará la capacidad de los reanimadores para realizar RCP
ABSTRACT

Objectives:

1) To compare the mean number of external chest compressions (ECCs) performed by male and female university students working on a mannequin for 20 minutes, analyzed according to body mass index (BMI), aerobic capacity, and muscle strength; 2) to analyze the association between BMI and physical fitness and the percentage of high-quality ECCs; and 3) to establish the optimal peak oxygen consumption (VO2 max) and muscle strength cutoffs for performing high-quality ECCs.

Methods:

Quasi-experimental study of 63 university students. We measured BMI, aerobic capacity, and hand muscle strength. The subjects were trained in cardiopulmonary resuscitation (CPR) and then performed CPR maneuvers on a mannequin for 20 minutes.

Results:

A mean (95% confidence interval) of 77.8% (65.1%-90.5%) of the ECCs performed by men were technically correct and 86.0% (71.7%-94.3%) were of adequate depth; women performed a mean of 41.2% (32.2%-50.1%) of the ECCs correctly and 43.7% (24.6%-52.9%) were of adequate depth (P ≥.001). After adjustment for age, BMI, aerobic capacity, and muscle strength however, the differences between men and women were no longer significant. Individuals who were of normal weight or overweight and had superior aerobic capacity and muscle strength achieved higher percentages of high-quality ECCs. BMI, aerobic capacity, and hand muscle strength were predictors of ECCs that reached adequate depth according to multiple linear regression models controlling for age and sex. The area under the receiver operating characteristic curve for predicting percentage of correct ECCs was 0.867 for VO2max and 0.872 for hand muscle strength. The cutoffs were 44.45 mL/kg/min for VO2max and 30.22 kg for hand strength.

Conclusions:

Gender, anthropometric characteristics, and physical fitness affect the ability to perform high-quality ECCs. Our data suggest that maintaining adequate physical fitness would improve individuals' ability to perform CPR
