Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This prospective, randomized, pragmatic clinical trial will compare HFNC to provider choice of usual care in these high-risk patients.
Randomization will occur at the time that the patient is deemed ready for extubation by the attending physician in the cardiovascular intensive care unit. Through randomization, patients will be assigned one of two physician order sets in the electronic medical record system: standard order set with or without recommendation for the use of HFNC. Reintubation and outcome data will be collected until patient discharge.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
High Flow Nasal Canula Oxygen Therapy
Participants will be assigned post extubation physician order set which recommends the administration of oxygen therapy via HFNC. HFNC is a heated and humidified system that allows prescribed fraction of inspired oxygen (FIO2) levels to be delivered at very high flow rates.
Recommendation for high flow nasal cannula oxygen therapy order set
Participants will be assigned post extubation physician order set which recommends the administration of oxygen therapy via HFNC. HFNC is a heated and humidified system that allows prescribed fraction of inspired oxygen (FIO2) levels to be delivered at very high flow rates.
Provider Choice Standard Care
Participants be assigned standard provider choice of standard care therapy physician order set.
Provider choice standard care order set
Participants will receive order set with provider choice of standard care therapy.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
* Undergoing cardiac surgery, defined as a documented surgical service of "cardiac surgery" in the electronic health record, performed in the main operating rooms at Vanderbilt University Medical Center
* Admitted to the cardiovascular intensive care unit postoperatively with an endotracheal tube in place and mechanically ventilated
* Surgery duration (documented time between "Anesthesia start" and "Anesthesia stop" in the EHR) of at least 180 minutes
* Received an order to be extubated by a treating provider o Patients who meet all other criteria but do not receive an order to extubate will be randomized but not enrolled
