Why is prolonged intubation associated with unfavorable outcomes after cardiac surgery, and how does this support the need for a fast-track extubation (FTE) protocol?  

What evidence from previous studies supports the implementation of FTE protocols in cardiac surgery? 

What were the key findings related to time to extubation and ICU length of stay, and how statistically significant were they?

What impact did the educational video have on ICU nurse performance, and how was this evaluated? 

How might hospital staffing levels, such as ICU nurse shortages, affect the feasibility of scaling this protocol? 

How can we apply this article to our unit?
