PARAMETERIZATION OF RESPIRATORY RATE ALARMS IN MECHANICAL VENTILATORS OF PATIENTS DURING THE BATH

Abstract

Objective: to measure the effects of parameterizing the audible respiratory rate alarms of mechanical ventilators to reduce the number of alarms triggered during bed bath. Method: pragmatic clinical trial, to compare the number of alarms of the mechanical ventilator, in the groups: intervention-the Respiratory Rate alarms were parameterized at the beginning of the bath; control-no parameterization performed. Study registered on 27/08/2019 in the Brazilian Registry of Clinical Trials, RBR-6y6tyc, Rio de Janeiro, Brazil. Results: Regression models showed that parameterization, performed and maintained during and after bath in the intervention group, had the effect of increasing the average number of high respiratory rate alarm triggers by 12.5 and 6.4 times, respectively; and had no effect on low respiratory rate alarms. Conclusion: The contribution of this study is to assist health professionals in formulating protocols for individualized parameterization of alarms for Mechanical Ventilators.
