While monitoring an active infant through a transcutaneous blood gas system, you notice a rapid rise in P_tcCO₂ from 63 to 145 mm Hg. During the same time, the (P_tcCO₂) drops from 35 to 7 mm Hg. What is the most appropriate action in this case?

The rapid rise in P_tcCO₂ and drop in (P_tcCO₂) is indicative of an air leak or dislodgment of the sensor. Checking the sensor for a leak or dislodgment is the appropriate action in this case. A quick assessment of the infant's airway may also be done if it is suspected to be the cause of the change in values, but checking the sensor should be done first. Stabilizing the infant and calling for emergency assistance may be necessary if the situation worsens or other concerning symptoms arise. Removing the sensor and recalibrating the instrument is not necessary at this point.
