pft hazards and the standard operating procedures for administering the test
184.108.40.206 (talk) 16:55, 20 August 2015 (UTC)I'm a merchant seaman. I take a physical annually and part of it is a benzene test. part of the benzene test is a pft test except that all it requires is that I inhale until I'm at full lung capacity then forcefully exhale through the machine until my lungs are empty and then push some more. my question is is this; is dizziness, light headed and or fainting a known ( it will happen) side effect. which is standard procedure sitting down or standing up ?who is qualified to administer the test?
