A neonate of 30 weeks' gestation shows signs of respiratory distress after delivery, including grunting, nasal flaring, and cyanosis
The baby is placed on nasal CPAP at 6 cm H2O with an FIO2 of 0.6. The grunting and nasal flar-ing are alleviated, and the ABG results on these settings are: pH = 7.20, PaCO2 = 64 mm Hg, PaO2 = 48 mm Hg, SaO2 = 70%, HCO3? = 21 mEq/L. The respiratory therapist should recommend which of the following? a. Increase the CPAP to 8 cm H2O and the FIO2 to 0.7. b. Switch to nasal IMV, an inspiratory pres-sure of 18 cm H2O, PEEP of 4 cm H2O, and an FIO2 of 0.8. c. Continue with the current settings and monitor the patient closely. d. Intubate and use PC-IMV, an inspiratory pressure of 16 cm H2O, PEEP of 5 cm H2O, and an FIO2 of 0.8.
