The thing to remember is not everyone who dies onboard is travelling alone so you must be compassionate to their companions. Our company policy is we would try to resuscitate the pax with aid of the de-fib onboard, regardless. Personally I think the decision to stop resuscitation should be made by any doctor/nurse in attendance, the crew envolved and of course the family!. Again the point of covering the body up should be made by the family. Their feelings in this situation is the number one priority. I would try to re seat the family/companions so they are seated with the body. Our S.E.P states that the body should be placed aft of a bulkhead preferably with any companions, family or any medically trained pax in the four seats infront. This of course is a very distressing situation I would like to think that anyone would treat any deaths onboard with dignity ( what if it was your mum or dad?) and not prop them up with a news paper in order not to cause any distress to other pax. Maybe using the same procedures that we would use for a stretcher case would be appropriate by proping up blankets etc to sheild the families/companions and the unfortunate persons privacy!.
