"Count backwards from 10" is the classic line from your anesthesiologist that is said to patients before they drift off to sleep. We aim to teach you Anesthesia before you nod off with interesting, fun, and quick ‘chalk talks’ and infographics on a wide variety of topics in Anesthesia.
With your help on requesting topics you want to see covered, our goal is to teach Anesthesia and Critical Care for FREE on a large scale! #FOAMed
I had a bad cold or flu last week and for 1.5 hours while I was trying to sleep on my back I was constantly coughing and I had a lot of gurgling and bubbling of fluid in my lungs. I've had that before so I was not alarmed but it was distressing to think I had the whole night ahead of me. I flipped over to sleep on my stomach and ALL of the bubbling and gurgling in my lungs went away and the coughing reduced to near zero. I was shocked at how dramatic the change was. I was basically able to sleep the rest of the night. I also slept on my stomach the 2nd night, though I had a little bit of coughing but I was eventually able to sleep most of the night. To sleep on my stomach I sleep with my head on the edge of the pillow so my face is angled slightly down and I prop up my shoulder with 3 folded towels and I also lift my hip on that same side with a crumpled up bedsheet. This reduces the amount of neck rotation needed to sleep on my stomach. Another trick is to add something to keep your head from sliding off the pillow. It's hard to describe but basically I use pillowcase with the T-shirt in the end of it that sticks out from under my pillow and that creates a stop (like a wedge) to prevent my head from sliding off the side of the pillow. I've worked out these tricks for sleeping on my stomach over the past 2 years because I find stomach sleeping helps me sleep a lot better. I'm 57 years old and turning my head to the side to sleep on my stomach is more difficult than a younger person, so these methods reduce the amount the head needs to be turned for stomach sleeping.
If we set rate @ 12 and patient breathes 20 on his own, so the patient gets a total of 32 in SIMV (12 supported as well as 20 unsupported patient breasthes) ?
i was learning Bipap (universal) and simv and i was a little bit confused with time limits in the Respirator for the phase to switch, id he doesnt breath for how long, when is the Respirator going to deliver another machine breath
How does the pressure wave from the artery get transmitted to the fluid filled tubing without blood getting in the line? And how does it exert a pressure wave if the bag of saline is exerting its own pressure?
thank you its a confusing yet important topic but you really made it easy to understand . pls keep up the good work and bring more helpful videos like this in the future.
This may be a silly question but I'm new to this... can you explain tidaling? Why does water level increase with inspiration, decrease with expiration, and the opposite is true for mechanical ventilation?
Hi. Could you pls explain the concept of using the anesthesia machine to perform a valsalva maneuver (indications, how to actually perform on the anesthesia machine, etc. ). Pls keep up the excellent work. Thank you.
What's your thoughts on the utility of precordial doppler for routine monitoring for VAE in a patient with an intracranial mass removal in the sitting position?
I really wish vet would give more "full disclosure" regarding their use of buprenorphine with dex-medetomidine for short-term "sedation"....they said they would administer a reversing agent (for the Presidex) but the buprenorphine was not reversed (and really can't be) and b/c of the 22 hour half-life...it took our dog around 4-5 days to recover from a simple X-ray procedure. This is the danger when drug companies start pushing drugs to vets, who themselves don't really understand just what they are handling. I guess Vets don't want to handle the short-acting narcotics these days. Our other dogs recovered within hours after these kinds of procedures in the past. So the medetomidine was "controllable" but the buprenorphine they use in combo screwed things up. Ask questions people when you go to the vet and get clear answers.
