A preterm newborn weighing in at 2300 grams (2.3 kg) is intubated with a 3.5 ETT and is currently on pressure-control ventilation. Current settings, parameters and ABG are as follows: 10:00 AM 2:00 PM Mode PCV PCV Mandatory rate 35 breaths 35 breaths Pressure cm H2O 30 cm H2O 40 cm H2O PEEP 5 cm H2O 5 cm H2O FIO2 0.45 0.45 Exhaled VT 8.5 ml 10 ml Measured PIP 30 cm H2O 40 cm H2O pH – 7.24PaCO2 – 70 torrPaO2 – 69 torrHCO2 – 24 mEq/LBE +1SaO2  – 91%What must be done to correct the problem?

Several  hours after birth, a term neonate develops tachypnea and mild hypoxemia but has a normal pH and PaCO2.  A chest x-ray shows some hyperinflation with fluid in the lung fissures. The infant responds well to low FIO2s by NC.  Which of the following is most likely the problem?
