PURPOSE: Analysis of ventilator graphics is a tool used to optimize ventilator parameters and to recognize and treat patient-ventilator dyssynchrony. Although proficiency on these interpretative skills may have a tremendous impact on the outcome of patients undergoing mechanical ventilation, critical care physicians (CCP) often times do not receive structured training through educational sessions. Instead, they learn to interpret ventilator graphics by constantly managing patients in the ICU and by attending sporadic presentations at academic meetings. The purpose of this study was to evaluate the impact of an educational program on ventilator graphics in a group of critical care physicians with different levels of expertise.
METHODS: The department of respiratory care designed a series of modules to train RT students and critical care physicians on the interpretation of ventilator graphics. Six 1-hour sessions were administered every two weeks to physicians in the division of pulmonary and critical care at the University of Texas Health Science Center at San Antonio. The course covered basic interpretation of scalar and loops and included short videos, lecture, and simulated ventilator scenarios. Participants included critical care physicians (CCP; n=3) and fellows of pulmonary and critical care during their first (PGY4; n=4) and third year (PGY6; n=3) of training. Prior to administration of the course participants were asked to score on a scale of 1 to 10 their perceived knowledge of ventilator graphics. A 26-item assessment tool was used before and after the course to evaluate impact of the program.
RESULTS: There was a 40.7% overall increase in the scores after the course (p < 0.01). The most significant change occurred in the PGY4 group (56.15%; p= 0.007) followed by the CCP (38.23%; p= 0.07), and the PGY6 (28.71%; p= 0.006). Their perceived level knowledge improved by a mean of 259% after the course. The most significant change occurred in PGY6 (350%) followed by PGY4 (333%) and the CCP (94%).
CONCLUSIONS: The implementation of a short course on ventilator graphics designed by a department of respiratory care significantly changed the perceived confidence and knowledge scores on the interpretation of ventilator graphics of critical care physicians.
CLINICAL IMPLICATIONS: Implementation of formal education on mechanical ventilation and ventilator graphics with participation of respiratory therapy can improve understanding of critical care montring and potentially improve clinical outcomes.
