Abstract
Objective: This study aimed to probe the correlation between lung ultrasound score (LUSS) and the arterial oxygen pressure to the inspired oxygen fraction ratio (P/F ratio) in patients with respiratory failure on the first and second days of intensive care unit (ICU) care.
Design: This was a prospective, analytic study of LUSS and P/F ratio values below 300 in patients under mechanical ventilation.
Setting: We conducted in the ICU of Wahidin Sudirohusodo Hospital Makassar, South Sulawesi, Indonesia, in April 2024.
Patients and participants: Patients with respiratory failure on mechanical ventilation.
Measurement and results: All patients were examined using GE Logiq V2 ultrasonography and blood gas analysis. Of 52 patients, the mean age was 41.62±15.83 years. Most of the samples were male (61.5%), with the majority having a normal body mass index (BMI). In cases of improvement, there was a significant relationship between the LUSS and the P/F ratio of patients with respiratory failure under mechanical ventilation on the first (r=-0.851, p<0.001) and second day (r=-0.682, p<0.001). In cases of worsening LUSS (n=6), it was found that there was no significant relationship (p>0.05) between the LUSS and the P/F ratio of patients with respiratory failure on mechanical ventilation either on the first or second day.
Conclusion: There was a significant correlation between LUSS and P/F ratio on the first and second day in cases of improvement in patients with respiratory failure under mechanical ventilation.
