You are the RT working in a CVICU. As you complete a ventilator check on an intubated bariatric patient with heart failure, you note that the patient’s pulse oximeter is not displaying reliably. After assessment, you determine that the patient’s poor perfusion is contributing to the unreliable monitoring. You consult the pulmonologist and other members of the interdisciplinary team to determine how to best monitor the patient’s gas exchange and oxygenation. The team does not expect the patient to be extubated in the next 24-48 hours. What should you recommend to the team?
