Summary

Propofol is a drug that is often used as a general anesthetic during surgery, but is also used for its sedative effects in the ICU setting. Notably, the drug can slow down both the respiratory and cardiovascular systems, causing respiratory depression, a low blood pressure, and a slow heart rate. As the nurse, be sure to closely monitor these vital signs and notify the provider if they fall below a normal range.
