Man, the parallels between anesthesia and aviation are unnerving. This post shows that UT is not "monitor dependent", like alot of pilots today are "GPS dependent".
In aviation today, with all the GPS advanced technology, knowing where you are at any time is so much easier than it used to be. All you have to do in the airplane is look at your moving map which depicts your airplane in the middle, and say to the air traffic controller, "five miles east southeast of AEX VOR." Before GPS the pilot had to use 2 VORs (a VOR is a land based navigational instrument that receivers in your airplane pick up; using two VORs you can use trigonometric principles to triangulate your position) to determine position (well,..theres another instrument, the DME, distance monitoring equipment, but we'll omit that for this conversation). With GPS monitoring exact location is made much easier.
Same in anesthesia with SPO2, BP, etc. A clinician knows exactly where the patient is at. But what if a monitor fails? Or what if a scenerio presents itself, like prone positioning, where monitoring during that certain time becomes beyond laborious?
This is where you can tell a clinician from a non clinician. Remember 30 years ago pulse ox was non-existent, BPs were palpated, ECGs were on a flinstone oscilliscope, and the clinician had to be well in touch with how the patient looked, felt, and sounded.
Gain the "old school" principles of patient well being (or old school navigation), and you have mastered your craft.
When you can feel comfortable by looking at the patients color, nailbeds, and strength of radial pulse, you have mastered anesthesia.
And when you know where you are in an airplane at a moments notice without the luxury of GPS, you are on your way to being a stellar pilot.
