chest wall rigidity ... high narcotic loadscan leadto difficult mask ventilation
various potential factorscausingdifficult mask ventilation
one or more of : ( 1 ) a low - resistance alternative path due to an inadequate seal , ( 2 ) an increase in air - flow resistance along the path to the lungs , or ( 3 ) a decrease in compliance of the lungs and/or chest wall leading to increased distal pressure(passive) must be caused bythat difficult mask ventilation
This may be aggravated by the abnormal upper airway anatomy , especially in the presence of OSAcausingdifficult mask ventilation and intubation
