The standard of care to evaluate the oxygenation status of a premature infant with RDS is by:
a. capillary blood gas (CBG).
b. arterial blood gas (ABG).
c. capnography.
d. pulse oximetry.
e. transcutaneous monitoring.
D
Because of the difficulty of obtaining arterial blood gas (ABG) samples from newborn and pediatric patients, capillary blood gas (CBG) samples are usually used to determine the pH, PaCO2, and HCO3? (i.e., the acid-base and ventilation status only). Capillary PO2 values are unreliable and should not be used for clinical analysis. The standard practice of care to evaluate the oxygenation status in these young patients is pulse oximetry (SpO2).
