I just did my first HSE Diving Medical took about 2 hours and cost £200.
Stage 1 with Nurses: Strip down to boxers and put robe on
Urine sample Pulse and blood pressure
ECG Large sample of for full blood count
Hearing Test in sound proof booth
Colour blindness and sight test
Lung capacity - lots of blowing through tubes in various ways
Aerobic capacity - heart rate gets monitored doing step ups in time to beat
Lung capacity again 5 and 10 minutes after exercise
Stage 2 with Doctor The doc does a whole series of tests checking your senses, coordination, reflexes and balance. Lots of prodding and pushing. He sets of this tuning fork and sticks it on your ankle - you have to tell him when its stops vibrating. He has a pin thing with a blunt and sharp end - he jabs you with it in various places and you have to tell him whether its the sharp or blunt end. Plus drop your shorts and cough to check for hernias.
I got the all clear for diving. Still waiting for blood test results but the Doc the HSE only check for sickle cell which is typically found in people with a Mediterranean origin. So chance of me having it very remote hence they issue the certificate straight away.
Nice to get it over with - was bit of a worrying before wondering if they would find anything
:P
