ETT, NGT and right jugular CVL are well positioned.
Diffuse hazy and coalescent airspace opacification bilaterally with a predominance in the lower and mid zones (which has increased from the initial daily CXRs).
The patient was treated for ARDS and made a slow recovery, spending 10 days in ICU. This was despite antivenom which was given in the emergency department 1 hour after the bite.

ARDS in this case is probably multifactorial due to all these effects (at least this is what was hypothesised by the ICU physicians and toxicologists).
