I have been to one of his courses. He teaches a 15 lead EKG. His presentations are pretty impressive. The key note for me was the caponography. This is the keystone to determining tube placement. Caponography can provide some insight into breathing disorders helping the medic correct the O2 exchange problem. The caponography connects to the tube and you get a read out of exhaled CO2. You should see nice tombstone readouts with a reading of ETCO2 at normal limits. Here is a link that is unrelated to the post above.
