Pulse oximeters over-report blood oxygenation for darker people.
This results in darker people receiving less supplemental oxygen than they need during medical emergencies, and having 3 times higher risk of hypoxemia, etc.

Having gotten more context... Hi, EMS provider here. Do not do this. It will kill you. Bubblers are one-way valves. This would prevent exhaled gas exiting the breathing circuit. This causes rebreathing of CO2, then hypercarbemia, hypoxemia, followed by cardiac arrest. Practice kink safely.

You cannot overdose on fentanyl by touching powder on a doorknob. Period.
But if you think you are overdosing, you should not drive your car…which you also shouldn’t do if you are having symptoms that are not consistent with fentanyl like this person did. “Responding to Narcan” is placebo effect.

As U.S. measles cases approach last year's record-breaking total, studies showed cases of encephalitis and sepsis among the hospitalized patients.
Hypoxemia and pneumonia were the most common conditions, with some admissions driven by electrolyte abnormalities, sepsis, and shock.
