Abstract Objective To explore the efficacy and safety of high frequency chest wall oscillation (HFCWO) expectoration intervention combined with lung ultrasound-led postural drainage in mechanically ventilated patients. Methods A total of 100 patients with invasive mechanical ventilation who were admitted to the First Department of Critical Care Medicine, North Campus of Yancheng First People's Hospital from August 2020 to August 2021 were selected as subjects and divided into the control group and the observation group by random number table method, 50 cases in each group. Both groups were given standard routine treatment, the control group was given HFCWO treatment, and the observation group was combined with lung ultrasound-led postural drainage on the basis of the control group. The oxygenation index (OI) was compared between the two groups before treatment and 3, 7, and 14 days after ICU admission. The circulation indexes (heart rate [HR], mean arterial pressure [MAP] and respiratory rate [R]) of the two groups were compared 10 min before treatment (T0), 15 min after treatment (T1) and 10 min after treatment (T2). The recovery time of the two groups was compared. Results There was no significant difference in OI between the two groups before treatment (P＞0.05). After 3, 7 and 14 days of ICU admission, the OI levels of the observation group were higher than those of the control group, and the differences were statistically significant (P＜0.05). There were no significant differences in HR, MAP and R at T0, T1and T2between the two groups (P＞0.05). The mechanical ventilation time and ICU stay time of the observation group were shorter than those of the control group, and the differences were statistically significant (P＜0.05). Conclusion HFCWO expectoration intervention combined with lung ultrasound-led postural drainage in patients with mechanical ventilation has a significant clinical effect, which is helpful for the implementation of precise chest physiotherapy strategies, and the circulatory indicators are relatively stable, improving the oxygenation of patients, thereby accelerating the patient recovery.
