About this study

The goal of this clinical trial is to learn if fasting or not fasting before a procedure has an effect on recovery in those who are critically ill. The main questions it aims to answer for patients on a breathing machine who are receiving tube feeding are: * Does the risk of lung complications and death differ between those who are not fasting, which may have a higher chance of allowing tube feeding to enter the lungs, and fasting, which temporarily stops nutrition before a procedure? * Is there a difference in recovery times, hospital stays, infection rates, need for organ support, safety, and nutrition for those who either fast or do not fast before a procedure? * What is the relationship between nutrition and clinical outcomes? Researchers will compare not fasting and fasting to see if it has an effect on recovery. Participants will: * Be assigned by chance (like a coin toss) to one of two groups. One group (fasting group) will have their tube feeding stopped at least 8 hours before their procedure. The other group (not fasting group) will have their tube feeding stopped right before their procedure. * Be monitored via medical record for amount of protein and calories received, and any complications related to fasting/not fasting. * Data from routine electronic medical records will be reviewed to determine how participants are doing 3 months after their procedure.
