IMG_1479.jpg I'm a rookie at machining but I lost my my favorite kiddie precordial (a special stethoscope us anesthesiologists leave on a patient's chest during surgery) so I wanted to make one . It attaches to a single molded earpiece so I can listen constantly but have my hands free. I used stainless and brass to try new materials. IMG_1480.jpg

Hey that looks good. Nice knurling.
I have always wondered what y'all are listening for with those things. I mean, ya got a pulse ox and and ecg. Why listen?

Why listen?

Probably for the same reason we operate a machine with one hand on it, just to feel the vibrations, waiting the ones that sneak up on us and suddenly overwhelm the machine. It's just a little more insurance.
 
Listening over the suprasternal notch lets you hear every breath very close to the vocal cords. You can get a great sense 0f the depth of anesthesia (squeaky high pitched~patient is "light", you can detect laryngospasm way before any changes in any monitor. It's old school but is a part of the "art" of anesthesia. Us old timers who learned before the pulse oximeter was in use really depended on the five senses. I see no reason to not use em still.
 
Got it. Thanks. Good to know.
So pretty much what T Bredehoft said!
