Air available at depth is under pressure. The deeper the depth, the more pressure required. Just like a regulator.
sorry, I was wrong. The ADS does maintain 1atm pressure inside. ADS is a hard suit designed to maintain constant presdure. For those interested google ADS diving.

Hi smenkhare,
If by ADS you are referring to an atmospheric diving suit, these devices indeed are designed to maintain an internal pressure of one atmosphere and do not involve breathing compressed gas from a regulator. ADS units involve rebreather systems and/or gas cylinders carried externally.
However, atmospheric pressure isn't the primary problem with asthma & diving. Such factors as cold, exercise & breathing hyper-dry gas are the main concerns. Even controlling for thermal issues (which is relatively simple with an ADS) & hyper-dry air, the matter of exercise & an exercise-induced asthmatic attack remains large. Many of these units are heavy, cumbersome & present a large surface area to currents.
Of course the enormous cost & technical/logistical support required for the use of ADS’s puts them beyond the reach of 99.9% of the diving population.
