*A common option is to choose a DIN regulator with a yoke adapter, useable
on either type valve.
If I feel discomfort in a body air space while ascending, the correct action is to:
a. Stop, descend slightly and give trapped air time to work its way out.
b. Continue my ascent while blowing against blocked nostrils.
c. Descend at least 10 metres/33 feet, then resume my ascent.

a. Stop, descend slightly and give trapped air time to work its way out.
*If you feel discomfort in any air space during ascent, immediately slow or
stop your ascent. Descend a metre/few feet to reduce the discomfort and
give the trapped air time to work its way out. Ascend more slowly, giving the
expanding gas time to exit.
During a dive, I swim hard to keep up with a fish that interests me, but shortly begin to
feel like I can't get enough air. The correct action would be to:
a. Signal my buddy and head up to the surface.
b. Use the regulator purge button to boost air flow.
c. Stop all activity and rest to restore proper deep, slow breathing.

, c. Stop all activity and rest to restore proper deep, slow breathing.
*Avoid getting winded or out-of-breath underwater. If you're faced with a
problem while diving, stop what you're doing, then reduce anxiety by
maintaining or restoring slow, deep breathing as you handle it.
