What is normal neonatal PaO2?
What is normal neonatal PaO2?
Normal Values
| Arterial Blood Gas | Normal Values |
|---|---|
| PaCO2 | 5 – 45 mm Hg |
| PaO2 | 50 – 70 mm Hg (term infant) 45 – 65 mm Hg (preterm infant) |
| HCO3 | 22 – 26 mEq/liter |
| Base Excess | -2 – + 2 mEq/liter |
What is normal PaO2?
Normal Results Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa)
What is PaO2 mean?
Partial pressure of oxygen
An ABG measures: Partial pressure of oxygen (PaO2). This measures the pressure of oxygen dissolved in the blood and how well oxygen is able to move from the airspace of the lungs into the blood.
What is the normal range for pO2?
ABG (Arterial Blood Gas)
| pH | 7.31–7.41 | |
|---|---|---|
| pCO2 | 41–51 torr | 5.5–6.8 kPa |
| pO2 | 30–40 torr | 4.0–5.3 kPa |
| CO2 | 23–30 mmol/L | |
| Base excess/deficit | ± 3 mEq/L | ± 2 mmol/L |
What is ABG test for newborn baby?
A blood gas is a blood test that looks at the acid and base balance and oxygenation level in a newborn’s blood. Blood gasses are some of the most common blood tests used in the NICU, as they pack a ton of information about your baby’s health into just a few drops of blood.
What causes neonatal respiratory acidosis?
Respiratory acidosis results primarily when alveolar ventilation is decreased or when carbon dioxide production is increased. Many clinical scenarios contribute to inadequate removal of carbon dioxide from the blood.
How do you interpret PaO2?
PaO2 is directly measured by a Clark electrode and can be used to assess oxygen exchange through a few relationships.
- Normal PaO2 values = 80-100 mmHg.
- Estimated normal PaO2 = 100 mmHg – (0.3) age in years.
- Hypoxemia is PaO2 < 50 mmHg.
What is normal newborn pH?
Normal arterial cord blood gases for a term newborn: pH: 7.18 – 7.38. PCO2: 32 – 66 (mmHg) HCO3-: 17 – 27 (mmol/L)
What is infant acidosis?
Interruption at any point along this pathway can cause fetal hypoxia, which is a potentially dangerous drop in oxygen supply to the baby’s tissues. Hypoxia can lead to acidosis, or a process by which the blood becomes abnormally acidic. This state of high acidity (or low pH) is referred to as acidemia (1).
How is neonatal respiratory acidosis treated?
The treatment of a respiratory alkalosis is to wean the mechanical ventilation by first reducing PIP or tidal volume, then respiratory rate.
