Agreed. The most important thing is to utilize all available resources.

Most major airlines have either company employed medical personnel (or more likely) they have subscription service to companies that provide that service, such as MedAire. The benefit of this type of program is that these outside companies often assume responsibility for liability in the event something goes wrong. We (the pilots) get patched through via an air-ground radio phone patch to Medaire and talk directly to their Docs.

Generally airline pilots aren't trained in any sort of medical techniques or first aid, simply because it isn't their job to treat an ill pax. It's their job to get the plane on the ground so that passenger can be treated by appropriately trained people.

Most companies put flight attendants through basic first aid training, including the use of the defib unit. Some companies also provide CPR training to FA's. Airliners are equipped with some basic medical equipment, including automated defib units, first aid kits, portable oxygen bottles, BP cuff, and an emergency medical kit which includes some medications such as nitro tablets, epi pens, and some other basic things that a doctor or other qualified medically trained person might utilize (the crew is generally NOT authorized to open the EMK on their own).

In the corporate environment, specialized training is more likely. At my company I am a certified Emergency First Responder, and our parent company aviation department (which has FA's) sends every flight attendant to be certified as EMTs (including recurrent training every 18 months)
