Thanks... his blood gases were perfect and xray looked great, I didn't want to give sedation because it wasn't affecting his gases and he would calm down immediately after his spells. He probably just needed the tube out, but the RT disagreed and just wanted to sedate. The other thing was during his desats his heart rate would increase and CO2 (from the TCom) would drop from the 50s to 30s during his spells. Thanks for your input :)
