Motion sickness among aeromedical staff is an important factor that may limit our ability to deliver effective in-flight patient care. Having experienced this once in the helicopter (an aerial search of the bays of the Manukau Harbour in gusty winds is not an excursion I would recommend to anyone wanting a sightseeing flight!), I can say that it is truly debilitating.

The Emergency Medical Retrieval Service of Scotland have a published SOP relating to air-sickness, including practical non-pharmacological methods of improving symptoms.
