Скачать или смотреть UWorld : IV drug use + AIDS + pneumonia = lungs acting like Airbnb filled with debris and regret.

Because the alveoli are literally stuffed, the V/Q ratio is trash → so even when you give oxygen like you’re sponsoring their lungs, the PaO₂ refuses to rise to full glory.
It’s not the oxygen’s fault — it’s the shut-down gas-exchange department inside.

Description

In pneumonia, inflammatory exudate fills the alveoli, causing V/Q mismatch. The lungs are ventilated poorly in affected regions, so even high FiO₂ fails to fully correct hypoxemia. This is commonly seen in immunocompromised IV drug users, where infection risk is high and gas exchange efficiency plummets. Management focuses on treating the infection and improving aeration—not just turning up the oxygen dial.
