I am sure I was on oxygen when the blood was taken, as I had been on the flight down and in the ambulance. dont see FiO2 anywhere in report. the following was also in the report for the date of my admitance:
arterial blood gasses PO2 - 4.3kpa minimum 9.3
PCO2- 5.3 kpa rang 4.5 to 6
oxygen saturation - 63% perferable rate 90 to 99
PH - 7.338 lower than acceptable asidosis
blood gas repeat on 40%oxygen mask 6 l/min
PO2 - 11.5 kpa range 9.3 to 11
PCO2 3.2 kpa range 5.42 to 6
PH - 7.53
6 days later on 7/1/94
PI - "had drop to 79%"
patient time - 17 sec pt
control time - 13.5 sec pt range 11 to 16
ptt at this time - 41 sec control 33 sec
bleeding time - 2.5 range 2.5 to 8 min normal
I’m not accustomed to seeing ABG’s in KiloPascals so I converted these to Torrs. Your first ABG was pH 7.338 (slightly low) / pC02 40 (normal) / pO2 32 (extremely low). It is somewhat surprising that 40% O2 at 6 liters per minute via mask alone would bring your second ABG to 7.53 (too high) / pCO2 24 (low) / pO2 86 (normal). These latest data also cast some doubt on ARDS as the cause your respiratory problem. I’d be happy to expand on things if you or anyone else is interested.
I still can not sort out what PI represents in your reports. Is it possible that it is PL with L in lower case instead of an I? If that’s so, Pl could represent platelets. However, these are not usually expressed as percentages like you are reporting. Anyway, your PT and PTT on Jan. 7 were elevated which could be consistent with a DIC picture. Since this is several days after the bite, I’m not sure that venom was a contributing factor (what’s the usual half-life of venom components in a bite recipient’s body? Anyone know? Bryan?). You did say you were septicemic and this is a common cause of DIC in ICU patients.
The bleeding time is a reflection of platelet number and function. Yours was normal, indicating an adequate number of functionally intact platelets.
