Lowest Blood pH

Published

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

6.9 on a diabetic ketoacidosis pt...survived.

I've never seen a pa02 less then 30 - 40 - I remember taking one somewhere in that range and concluding it must have been venous. Repeat taken. Um....no.

I saw 7 yesterday on a GI Bleeder. He had been putting alcohol down his peg.

He had been putting alcohol down his peg.

I should be suprised, but I'm not. People try anything. I remember a mother once putting peas down her sons PEG tube....

6.96- 2.2kg full term (so they said) brought into NICU after difficult delivery, possible meconium aspiration. Said when the team went in, they were doing compressions. Had a HR of 100 when he came back (4 epis? I think...). Don't remember specifics on rest of labs, but off the wall. Chemstrip registered at 9 and 13!!! Finally went back up to 60-ish after several D10 boluses.

-PS- I'm only a student. Was observing in NICU one week, so if I have some wrong values, forgive me! Just seemed WAY off to me.

I had a pH of 7.14 last night pO2 of 46 through an A-line? Do you think he'll survive with those numbers?

The lowest I've ever seen was 6.72 in a child during E-CPR. We were successful in obtaining a return of circulation, but the patient ultimately died the next day. The lowest I've seen in a child who survived the ICU was 6.79, with a PO2 of 29 and a PCO2 of 141. This was also an E-CPR case, after which the child survived another 369 days but with severe sequelae; she actually just died last week.

pH 6.7, mixed metabolic and respiratory nightmare. Came from ER intubated, advanced sepsis. Bicarb drip at 250 ml/hr, maxed on multiple pressors. Chest xray a total white-out. Vent changed to an osscilator on arrival, quinton placed for CVVHD. Family called in to say their good-byes, and the pt passed within about 5 hrs after being made DNR.

The lowest I have seen was I think 6.7 and all of the other numbers were way off too. The pt ended up maxed on a bicarb drip, vasopressin, and epi. We coded the pt 3 times before the family decided to let us stop. We never really did figure out what was wrong with this pt either...

The lowest I've seen was 6.88 on a COPD patient right before we intubated him. His gases in the ER were ok on 3-4 liters nasal cannula but someone had the bright idea to throw a 100% non-rebreather on him.
