I never understood the concept of air trapping, thank you!

Incredible lecture thank you so much and love the speech over drawing. You all save millions of med school students.

Oh my God your voice 😍😍😍 I have fallen in love with your voice and thank you so much for such a nice lecture 🙏🏼

Great video! I'd say however, coarse breath sounds are more commonly heard in these patients and occasional wheezing. The wheezing one hears however isn't really narrowing in the airway as much as it is the air that pass through the fluid that causes the blockage. Air trapping is also not as common in these patients since bronchiolitis isn't an obstructive disease like asthma or COPD.

Thank you. Newly graduated Paramedic here. I've seen so much of this in the last month in little ones. I have a much better understanding of why they struggle so much.

My son picks up the RSV virus at least once a month since he was 8 months old (He is nearly 2 now). Thank you so much for helping to understand what is happening to him.

around 6:10, when talking about the effects of air trapping, I understand that the CO2 leaving the capillaries and going into the alveoli will be stuck, but for the O2, if the inhalation is normal, then why would we get hypoxemia? Wouldn't the perfusion of the blood vessels be maintained since the inhaled oxygen would still be diffusing against its gradient? Or does the gradual blocking of the alveoli/bronchiole entryway by the mucus plug eventually cause inhalation in the long run, such that we would get hypoxyemia? Also, as there is a gradual build up of CO2 in air trapping, would the alveolar level of CO2 increase so much as to surpass the bloods levels and we would actually get CO2 diffusing from the alveoli to the capillaries and get cyanosis? Thank you so much for your videos by the way! They've helped me understand countless diseases!!

Bronchiolitis is inflammation of smaller airways - there is mucosal edema, smooth muscle constriction , and excess secretions. All these cause narrowing of otherwise very narrow lumen of bronchioles. Thus inhalation of atmospheric oxygen reaching the alveoli beyond the bronchioles becomes less, thus causing Hypoxemia. Sorry for the technical terms, I presumed that you are a medical person.

Awesome

[@mercychelangat8426]

Thanks ..cool presantations...kindly asking which book do you use..or which book do you recomend for peadtrics

[@bilkisfatema3484]

That wheezing sound literally scared me!!!

[@NinaCrown45]

This is the second time I have bronchiolitis and I'm 46

[@ElijahXMedia]

ok but is there anyway to reverse this? I have this, i dont feel like you can....

[@doctoratta7007]

Great video but your voice was putting me to sleep, couldnt stay awake.

[@MultiMusik4]

I had it, and it is so bad I cant eat or drink

[@ElephantShoe..]

My mom too...
