The How, What and Why of EMS Pulse Oximetry
I think it was in 1986 that I first encountered a new technology called pulse oximetry. I was called in for a two-hour transfer of a patient with chronic obstruction pulmonary disease (COPD) from a small rural hospital to a large tertiary center in a larger city. I was an experienced paramedic and fairly confident in my skills and knowledge.
The patient was pretty sick as best I can remember. I took a report from the nurse and the doctor came up to me and said he was sending this patient with a machine called a "pulse ox."
"What does it do?" I asked.
"It measures their oxygen levels," he responded. "If the oxygen saturation drops below 90%, then you should intubate
them immediately."
I thought it was a pretty cool tool if it could tell you when to intubate! Wow!

Luckily, my patient's O2 saturation didn't drop below 90%, but I was ready if he did!
It didn't dawn on me at the time that I knew nothing about this new tool, but the impromptu two-minute training I received gave me a certain amount of confidence based on the pulse ox reading and what to do.
How many new tools do we purchase and put on patients without a full understanding of how the thing works? How many people use a cardiac monitor but aren't competent in rhythm interpretation? How many people run 12-lead ECGs but don't know how to interp...
