Ultrasound Scoring Methods to Monitor Breathing Problems in Intensive Care Patients

The goal of this observational study is to compare two lung ultrasound protocols for assessing lung function in patients with acute respiratory insufficiency treated in intensive care units. The main questions it aims to answer are: 1\. Is there a statistically significant difference between the established Baciarello (name of author) ultrasound protocol (12-point examination) and a new, abbreviated local ultrasound protocol (6-point examination) for assessing lung function? 2. Do the scoring systems of both protocols correlate with each other and with treatment outcomes in critically ill patients? Researchers will compare the Baciarello protocol (assessing 12 fields-6 per side of the body to a new abbreviated local protocol (assessing 6 fields-3 per side of the body) to see if both protocols provide same diagnostic and prognostic information for evaluating lung pathology and patient outcomes. Participants will: Undergo lung ultrasound assessment using both protocols Have their ultrasound findings scored according to each protocol's point system (0-36 for Baciarello; 0-18 for the new abbreviated protocol) Have their arterial blood gas values recorded (pH, PaCO2, PaO2, oxygen saturation) Be monitored for clinical outcomes including mechanical ventilation requirements and hospital mortality
