Incredible lecture. Will be watching this one over and over. On the edge of being diagnosed with ABPA and the exchange struggles I've been experiencing will be easier to relay to my Dr now. Keep up the great work 👍
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.
What about discussing surface area of prone positioning, gravity of oxygen to rise to the dorsal part of the lungs and the shift of fluids within the lungs during prone.
I think there is a mistake. You explained perfecly why the ventilation is greaten at the basis of the lung in comparison with the apex when the patient is staing-up. In don't understand why you change your mind when you talk about the same topic with the supine patient. I mean, it is the same thing. In clinostatism the dorsal region of the lung is better ventilated then the ventral region precisely because at reast the alveoli are smaler and auring the inspiration phase they can expand much better then the ventral alveoli. Please tell me if I'm wrong, becouse I can't understand why the prone position improve the V\Q ratio. Thank you
