The PaO2/FiO2 (P/F) ratio is same for all the Positive End Expiratory Pressure (PEEP) ≥ to 5. This P/F ratio misleads the severity of disease without the knowledge of set PEEP. The Oxygenation status is actually worse when the patient is using high PEEP. P/F Ratio doesn't include PEEP in the calculation.The P/F ratio doesn't show the severity of the disease appropriate for the set PEEP. PaO2/(FiO2 X PEEP) P/FP Ratio is a new Formula which addresses this gap to appropriately calculate the severity of the disease by including PEEP in the formula. This formula is used to predict mortality for different severities of ARDS.

To predict mortality of ARDS patients using P/F and P/FP Ratio
Timeframe: Baseline ABG done at (approximately 4 hour after intubation) to ABG done approximately 1 hour before Rescue therapy like Neuro Muscular blockage, Proning, ExtraCorporeal Membrane Oxygenator, and High Frequency Oscillatory Ventilation.
