You are transporting an intubated 7-year-old child who experienced a traumatic brain injury. Full spinal precautions have been applied, you are ventilating the child at a rate of 20 breaths/min, and an intraosseous catheter has been placed in the child's proximal tibia. Reassessment of the child's blood pressure reveals a reading of 70/40 mm Hg. You should:
A: give a 20 mL/kg crystalloid bolus and reassess blood pressure. B: increase the rate of ventilation to 35 breaths/min. C: raise the head of the backboard to lower intracranial pressure. D: ventilate as needed to maintain an ETCO2 of 35-45 mm Hg.
Your patient develops a fever while being mechanically ventilated in the control mode. As a re-sult of the fever, the patient's CO2 production increases while alveolar ventilation is unchanged
What is the probable change in ABGs? a. Increase in PaCO2 b. Decrease in PaO2 c. Decrease in PaCO2 d. All of the above
