Hi Elspeth. Got the chance for some training so went for it as I have never really been at altitude. They create the required 'gas' mix and then I put on a nose plug and a mouthpiece in and beathe the gas.
Did an at rest session today and did 30 mins breathing 'air' the equivalent of 14k feet, so about 11% ogygen. All went well with no ill effects. RHR was 59 dropping to 54 breathing room air before the gas was turned on, and my oxygen saturation level was 97%. Once on the low oxygen the saturation levels dropped quicky but settled and th lowest it went was 77%. The highest my RHR went to was 70. Within 3 mins of going back to room air my saturation was back up to 98% and my RHR down to 45.
Next session I will be walking. He was going to do 2 sessions at rest, but I handled it so well today that he decided just to get started on the exercise.
Tee hee: EPO the legal way
