You should definitely update the saint john's certification. A lot of things have changed. In practice, non medical related personel are not longer required to check for "normal" breath sounds. CPR now starts with 30 compressions (used to be 15), THAN 2 breaths (used to be breaths first). That's just the major changes. Lots of subtleties. None of this means your odds are better of surviving cardiac arrest, but it's a start.*

( random things about strained ankles )I brilliantly got rid of all 7 tenser bandages I had after chest surgery.
I haven't had a painkiller in my home in over 6 years. I donated the percoset I had prescribed post-chest surgery to a friend going in for her orchitectomy.
