Here are the "Ps" for those who wonder. I got this from the ASA web site; address noted at the bottom... P1 A normal, healthy patient. P2 A patient with mild systemic disease. P3 A patient with severe systemic disease P4 A patient with severe systemic disease that is a constant threat to life. P5 A moribund patient who is not expected to survive without the operation. P6 A declared brain-dead patient whose organs are being removed for donor purposes. A suffix of E added to P1-P5 delineates the procedure as Emergent. http://www.asahq.org/clinical/physicalstatus.htm In "my day" we used the ASA I, II, etc. So I was just wondering when the change to the P1 P2 came about....but maybe it really hasn't! Actually, if you plug "ASA physical status classification" into a search engine, you get an interesting mix of info...... Thanks to all who responded.....Keep up the good work! Austinrobi CRNA
