What is the minimum standard of medical care for a patient whose
esophogus is perforated by endoscope, abdominal cavity fills with air
thereby stopping heart?

Dear brojohn-ga:

In addition to being a Google researcher I am an emergency room nurse
and have personal experience in dealing with cardiac arrest.

The minimum standard of care for any patient whose heart has stopped
for any reason is essentially the same. It is directed to restoring a
viable cardiac rhythm and correcting the underlying cause. The
American Heart Association has published guidelines for dealing with
cardiac arrest and they are universal regardless of cause. They follow
what is called an algorhythm, which is a decision tree with specific
steps to follow in treating the patient according to clinical sign and
symptoms. These guidelines are known as the Advanced Cardiac Life
Support (ACLS) guidelines. They are based on medical research and are
updated every several years.

The current guidelines may be found at the following link but are very
technical in nature: http://www.ace.cc/new%20acls%20guidelines.htm

 In your scenario, once a viable heart rhythm has been established the
focus will shift to surgically correcting the internal damage done by
the perforation. But first things first! Getting the heart beat back
and stabilizing the patient are the number one priority.

Please understand that this information is academic in nature and do
not represent or replace professional medical advice.

I sincerely hope this is the information you were looking for.
