Lung ultrasound score will be done within one hour of admission,12 hours post admission then 24 hours in intensive care unit,follow up of patients will continue for 72 hours . a complete lung ultrasound evaluation will be performed using low frequency curved probe (2MHz-5MHz) according to the lung ultrasound score . The external lung fields will be examined by longitudinal and transverse plane scans, dividing the surface of the thorax into 12 zones: 6 on the right (anterior: upper R1 and lower R2; lateral; upper R3 and lower R4; posterior: upper R5 and lower R6) and 6 on the left side (front: upper L1 and lower L2; lateral: upper L3 and lower L4; rear: upper L5 and lower L6). LUS assigns 0 points to A lines or \< 2 separate B lines plus regular sliding; 1 point with lines B ≥ 3 or spaced focal points plus regular sliding; 2 points with coalescing B lines, and 3 points to pulmonary consolidations for each zone with a score ranging from 0 (normal lungs) to 36 (worst case scenario)
