Blood Gas Panels, Pediatric, Arterial or Venous
Laboratory:
Pediatric Blood Gas
Synonyms:
Blood Gas, Mott, Arterial Blood Gas, Mott, Venous
Blood Gases (pH, pCO2, pO2) Carboxyhemoglobin Co-oximetry
Cooximetry (Coox) (O2HB, COHB, METHB) Electrolytes, Whole Blood
Glucose, Whole Blood Lactate, Whole Blood
Methemoglobin Co-oximetry Oxyhemoglobin Co-oximetry
Container:
Heparinized syringe
Minimum Volume:
0.3 mL whole blood
Offsite Collection
Because of delays in transit, this test is not recommended for use by MLab clients. CAP requires all blood gas specimens to be analyzed within 30 minutes of collection.
Onsite Collection (UMHS Hospitals Only)
Specimen drawn into air-free balanced heparinized syringe with needle removed and syringe end with airtight cap. All specimens should be in ice slush and brought to the laboratory immediately. All specimens must be labeled with patient's name and hospital number. Indicate on the requisition the fraction of inspired oxygen concentration or room air if applicable. Precautions should be identified.
Days Set Up:
Daily, 24 hours
Analytic Time:
15 minutes
Reference Range:
Arterial: pH 7.35-7.45, Bicarbonate 22-26 mEq/l, PCO2 35-45 mmHg, PO2 80-100 mmHg, PO2 Newborns 60-70 mmHg, O2 saturation 96-97%. CRITICAL VALUES: PCO2 Low - less than 20 mmHg, possible effect: Complex interwoven patterns of acidosis, alkalosis, hypoxemia; PCO2 High - greater than 65 mmHg, possible effect: complex interwoven patterns of acidosis, alkalosis, hypoxemia. pH Low - less than 7.2, possible effect: complex interwoven patterns of acidosis, alkalosis, hypoxemia; pH High - greater than 7.55, possible effect: complex interwoven patterns of acidosis, alkalosis, hypoxemia. PO2 Low - less than 50 mmHg, possible effect: complex interwoven patterns of acidosis, alkalosis, hypoxemia.
Test Usage:
Evaluate respiratory function, lung disease, acid-base balance, carbon monoxide poisoning, fat embolism syndrome.
Test Limitations:
Arterial puncture may be extremely difficult in some individuals. O2 saturation is calculated on assumption of 100% A HgB. Reported value will be misleading whenever hemoglobins with different dissociation curves are present. Calculations assume body temperature of 37 degrees C and HgB of 14.5 g/dl unless otherwise stated.
Test Methodology:
Specific Electrodes
