What is the lowest Blood pH you have ever seen drawn on a patient?

[zambezi]

pH: 6.9 --> then 6.7 after 2 amps bicarb (needless to say, she passed on...)

Lowest pO2 I have seen is 33 (vent/100% FIo2/drawn from A-Line)

[CRNAsoon]

7.1 is the lowest I've ever seen. My pt also did not make it.

[VivaLasViejas]

6.9. This patient did get through the initial crisis, but never made it out of the ICU.

[janfrn]

6.73 on a teenager with sudden onset CNS collapse. He survived!!

Lowest pO2 I've seen is 27 on a neonate who went on ECMO and eventually died.

Highest pCO2 I've ever seen was 345 (ouch!) in a teenager with BOOP secondary to charcoal aspiration following Tylenol ingestion. She was conscious and c/o headache... Then she crumped. Got a double lung transplant, had multiple near-death experiences, slow recovery only to succumb to CMV pneumonia. Longest suicide I've ever seen.

I had a newly diagnosed IDDM come in with DKA - her pH was 7.01 and she was managed on the ward! She was unique in several ways - she was 50, was breast feeding her youngest child (aged four), and only had a BSL in the mid-tenties (our scale is different from yours - it's around 450 mg/dL). She had a really healthy diet to start with, which probably helped,a nd she didn't believe she was really that sick until I showed her her labs and told her she should have been in ICU. She survived

I have seen a pH of 6.9 and a pO2 of 18. These weren't in the same patient! Neither patient survived.

I know we've had those in the 6.something range but I have never personally seen this.

This is one of my favorite things to fix...a respiratory alk/acidosis. It's so rewarding after a couple of RN initiated vent changes.

pH of 6.8something. Suicide attempt by ingesting antifreeze. Surprisingly, the guy lived. I remember when the first gas came back and we heard the pH, one nurse said "is that even compatible with life?".

[AmiK25]

pH 6.7, pO2 17...trauma patient who did not make it. When I drew the gas, the trauma surgeon kept trying to tell me it was venous and no pO2 can be 17 (we had been basically coding this pt. for an hour). I reminded him that I drew the gas out of the art line that he inserted! He didn't say another word.
