Categorical data analyzed using Chi square and continuous data ‘Mann Whitney U’ test and student ‘t’ test. P value <0.05
^aOf the ventilation modes, synchronised intermittent mandatory ventilation(SIMV) was significantly associated with progression of IAH to ACS
^bOf those with IAH, the ones who progressed to ACS were significantly older than the rest
^csimilar to IAH, amount of IV fluids in 24 h was a significant determinant IAH progressing to ACS
