Purpose: This study was conducted to identify the effects of educational intervention on pre-test and post-test tidal volume, endotracheal peak pressure, and ventilation interval measurements during single-rescuer respiratory-assistant therapy by paramedic students.
Methods: The present study, with a quasi-experimental design, included a pre-test and post-test nonequivalent control group. A total of 62 paramedic students (31, experimental group; 31, control group) participated in this study. The intervention lasted 80 minutes. Data were collected from each student before the intervention and two weeks after the intervention, between September 3 and 21, 2018. The collected data were analyzed using IBM SPSS Statistics for Windows, Version 25.0.
Results: Tidal volume (p<.001) and endotracheal peak pressure (p=.002) measurements after the intervention were significantly different between the two groups. Analysis of covariance was used to control the variance (the pretest value of endotracheal peak pressure) in order to identify the effect of the intervention in the two groups. Endotracheal peak pressure was not significantly different between the two groups.
Conclusion: Education and training of paramedic students in emergency medical services on single-rescuer respiratory-assistant therapy is necessary for the emergency care of patients with respiratory arrest.
