She wasn’t asleep. She wasn’t crying. She was just staring straight ahead, not blinking, not responding when her parents asked if she was okay.
When they arrived at the ER, she was still conscious, but barely. While we were getting her hooked up to monitors, her oxygen levels started dropping. Her blood pressure followed.
Then her father sat down in a chair and told me he felt dizzy.
Within seconds, his speech started slurring. That’s when we stopped treating this like a routine visit and started ramping up tests.
We ran a blood gas test, and yup, it was Carbon monoxide exposure.
This family had a carbon monoxide detector. It was installed correctly. The battery worked. It was mounted exactly where the instructions said it should be. And yet, it never went off.
Most people think carbon monoxide poisoning is rare, dramatic, and obvious. They imagine someone collapsing suddenly or passing out without warning. That isn’t what it usually looks like.
By the time people realize something is seriously wrong, their ability to think clearly and react quickly is already impaired. That delay is what makes it so dangerous. And that delay is exactly how most standard carbon monoxide detectors are designed to function.
