Abstract: Objective To investigate the effect of progressive muscle relaxation training in awake prone ventilation in patients with acute respiratory distress syndrome(ARDS). Methods The quasi-experiment research method was used. 45 ARDS patients in a tertiary hospital in Hunan Province from May to July 2023 were selected as the experimental group,and the progressive muscle relaxation training program was used before prone ventilation. 45 ARDS patients from December 2022 to February 2023 were selected as the control group,and traditional prone- position ventilation was used. The maximum duration of a single daily treatment and the total duration of treatment in the first 3 days of prone position ventilation,tolerance,and the effect of treatment were compared between the two groups. Results The maximum duration of a single daily treatment [(3.68±0.71) h] of experimental group in the third day of awake prone ventilation was higher than that of control group [(2.50 ±0.67) h],and the total duration of treatment [(36.72±0.56) h] in the first 3 days of experimental group was higher than that of control group [(23.25±1.76) h] (P<0.001). The tolerance index (Visual Analogue Score-VAS) [(2.83 ±1.74) points] of experimental group was lower than that of control group[(6.17±1.11) points] on day 3 of treatment(P<0.001). The blood oxygen partial pressure and oxygenation index of experimental group were better than those of control group4 h after prone position treatment(P<0.001). Conclusion Progressive muscle relaxation training can effectively prolong the ventilation treatment time of awake prone position in ARDS patients,improve tolerance,and thus improve the therapeutic effect.
