Final answer:
The neonate's CBG results indicate a slightly low PaO2, which suggests a need to evaluate and possibly increase the supplemental oxygen therapy. Monitoring and further testing should be conducted to ensure appropriate oxygenation levels are maintained.
Step-by-step explanation:
The capillary blood gas (CBG) results for the neonate who is currently receiving 0.25 LPM nasal O2 show a pH of 7.35, PaCO2 of 44 mmHg, and PaO2 of 45 mmHg. According to the reference values provided, the neonate's pH is within the normal range (7.35-7.45), the PaCO2 is slightly elevated but within the normal range for males (35-48 mmHg), and the total venous bicarbonate is not provided but would usually range from 22-29 mM.
Given that the primary concern with these results is the PaO2, which is lower than the expected normal range for a well-oxygenated blood (which is >50 mmHg in neonates breathing room air), it indicates that the neonate may benefit from an increased supplemental O2 therapy. Consequently, the respiratory therapist (RT) should suggest careful evaluation and possible titration of the oxygen therapy to achieve appropriate target saturation ranges, typically aiming for an optimal PaO2 depending on the neonate's condition and gestational age. The RT should also consider factors such as the neonate's clinical status and the risk of oxygen toxicity when suggesting changes to oxygen delivery. Close monitoring and further testing are recommended to ensure that the neonate maintains appropriate oxygenation levels and to assess the effectiveness of any adjustments made to the therapy.
