The Effectiveness of Prehospital High Flow Nasal Cannula Oxygen Therapy to Reduce Intubation Rate in Patients with Dyspnea and Desaturation

High Flow Nasal Cannula Oxygen Therapy to Reduce Intubation Rate ปีที่

Abstract

High Flow Nasal Cannula is a non-invasive ventilator which is chosen as a treatment for patients with dyspnea and desaturation care. The purpose of this research was to study the effectiveness of High Flow Nasal Cannula oxygen therapy on the prevention of intubation in patients with dyspnea and desaturation during prehospital care. The sample of this study consisted of patients with dyspnea and desaturation during prehospital care. This study was a prospective study, nonconcurrent prospective clinical control design in patients with dyspnea and desaturation. The sample size was calculated under the assumption that the intubation rate in the mask and bag oxygen groups was 20% and in the high-flow oxygen group was 0%. The sample size was 100 people. Research instruments were data recording forms, presented as frequency, percentage, mean, standard deviation. Data were compared between experimental group and comparison group using the exact probability test, Wilcoxon rank sum test, independent t-test and multiple mixed effects model for repeated measures with statistically significant level at 0.05. The respiratory rate of the experimental group was significantly reduced statistically. The initial blood oxygen saturation levels were statistically significantly different, but at 30 minutes, they were not different. The comparison group has three patients on intubation, but the experimental group has no intubation. Therefore, further studies are needed to identify factors affecting intubation in patients with dyspnea and low blood oxygen saturation levels.
