Screening for acute mountain sickness (AMS)

Useful questions for diagnosis of AMS, in the proper setting and after considering the differential diagnosis:
Do you feel sick?
Do you feel hungover?
Overall severity of AMS symptoms and associated points:
No reduction of daily activity:	0
Mild reduction:	1
Moderate reduction:	2
Severe reduction (bed rest):	3
Answering yes to one or both of the first questions combined with an overall severity of >2 correlates closely with AMS.
