I am not aware of any difference between medical O2 and what is carried in crew bottles. It is all Oxygen.
I think private pilots learn about this.
Medical O2 has water vapor (normal ambient humidity) so as not to dry out the patient's lungs and throat.
Aviation O2 is dry, so that it doesn't form ice in the delivery system when the regulator drops the pressure, and subsequently the temperature.
