my goodness, thank you! spent so long trying to figure out why the pressure change in the extrathoracic area on inspiration. such a simple concept I wasn't thinking of. thanks again!

I'm a nursing student in Taiwan, and this video helped a lot with my physiology learning. The explanation and especially the graphics were so great, which made the learning interesting. Here is the note of the video in Mandarin, though I don't know how many students using the same language will watch this, just hope it helps! part1 1. extra-thoracic obstruction胸腔外阻塞 2.可能病因subglottic stenosis聲門下狹窄、tracheal tumor氣管腫瘤、goiter甲狀腺腫大、vocal cord paralysis聲帶麻痺 3.吸氣時，呼吸道壓力低於大氣壓，阻塞處更加狹窄；吐氣時因呼吸道壓力大於大氣壓，因此阻塞處可維持撐開。所以flow-volume loop會有正常的吐氣曲線，與受阻礙的吸氣曲線 part2 1. intra-thoracic obstruction胸腔內阻塞 2.可能病因tumor of lower trachea within the chest下呼吸道腫瘤、tracheal strictures氣管狹窄、tracheomalacia氣管軟化症(氣管軟骨環軟化，變得可壓迫) 3.吸氣時，氣體順著較高的大氣壓流入壓力較低的氣管，可維持阻塞處開啟；吐氣時，胸內壓上升，壓迫胸腔內阻塞處氣道，阻礙氣體流出。所以flow-volume loop會有正常的吸氣曲線，與受阻礙的吐氣曲線

Aag laga di bhai 🔥🔥

The best explanation even! thank you so much for this!

Very helpful! Very well explained

Clearly explained, thankyou

This is brilliant. Thank you very much, sir.

Thanks for explaining

Thank you! This was excellent!

Professionally explained, thanx a lot :-)

Thank you!

thank you so much kind sir.

thanks not able to find the fixed obstruction video, can you share the link.

thank you so much

Very informative video. Requesting to make video on same topic with Resistance Loop in place of Flow Volume Loop.

thx

Thank you^_^

want the explanation of fixed airway obstruction , thank you!

Thank you!
