normal abg values for infants
An arterial blood gas (ABG) test measures the acidity (pH) and levels of oxygen and carbon dioxide in the blood. Technique, instrument (analyzer), and post puncture care. What are the disadvantages of an ABG sample? As (extreme) prematurity is a pathological condition in itself, be cautious when using the concept of ‘normal’. Arterial Blood Gas is usually advised to patients suffering from respiratory illnesses or under critical care. Normal values for arterial blood gas (ABG) Normal values are given below. But whether a value is normal or not depends often on the circumstances of the birth and other information. pH: 7.35-7.41 pO2: 80-100 mmHg pCO2: 32-48 mmHg HCO3: 20-29 mmol/L. Note: The “P” in PCO2 and PO2 stands for “partial pressure,” which is how these gases are measured. These ranges vary from lab to lab and depend upon the elevation above sea level. 59. Arterial blood gas test normal values shows values for pH, Oxygen, Carbon dioxide, Bicarbonates, Lactic acid levels and oxygen saturation. Arch Dis Child 2004; 89:176–80. Complex Child is an online monthly magazine about caring for a child with complex medical needs or a disability. The normal values listed here—called a reference range—are just a guide. Normal Values in Children During evaluation, conduct the primary assessment, secondary assessment, and diagnostic tests. Normal values of umbilical arterial samples in a preterm newborn: Median and centile ranges for umbilical cord blood gas and lactate values Normal arterial cord blood gases for a term newborn: pH: 7.18 – 7.38 PCO2: 32 – 66 (mmHg) HCO3-: 17 – 27 (mmol/L) PO2: 6 – 31 (mmHg) Comparison of blood gas values in arterial and venous blood. 60. Some ABG results also show hemoglobin and serum electrolyte values. Mg range for infant. Normal laboratory values are reference ranges used by clinicians to interpret results of laboratory tests. Yildizdas D, Yapicioglu H, Yilmaz HL, Sertdemir Y. Normal umbilical cord blood gas values are listed below. There are wide ranges of umbilical cord gas values which can be considered normal. 1.6-2.5 mg/dL They include: pH; Partial pressure of oxygen (PaO2) Partial pressure of carbon dioxide (PaCO2) Bicarbonate (HCO3) Oxygen saturation (O2 Sat) Oxygen content (O2CT) The aforementioned components all have different normal values and represent different aspects of the blood gas. If at any time a condition is determined to be life-threatening, intervene immediately. There are six key components to an ABG. Kirubarakan C, Gnananayagam EJ, Sundaravalli EK. Note that these may vary slightly between analysers. Test: Age: Range: Units: Testosterone, Total (Male) <1 month 1-5 months 6-24 months 2-5 years 6-9 years 10-11 years 12-13 years 14-15 years 16-18 years Tanner stage 1 Be sure to know the normal ranges and units for the analyser you will be using. What are the complications of an ABG sample? Your lab may have a different range for what's normal. Key Components to an ABG. pH: 7.35 – 7.45; pO2: 10 – 14kPa* pCO2: 4.5 – 6kPa* Normal. Correlation of simultaneously obtained capillary, venous and arterial blood gases of patients in paeditric intensive care unit. They are hard to obtain, can damage the artery, infection/ clotting, and stimulation of the infant will affect the values. In general, normal pathology values are readily available for healthy term infants.
