Nurse anesthetists monitor a patient’s anesthesia needs before, during, and after medical procedures. Nurse anesthetists are required to have a BSN and attend a master’s degree program in anesthesia. Like physicians, nurse anesthetists are often “on call” and must report to the hospital on short notice. Many nurse anesthetists are independent contractors, accepting jobs that require them to travel. This is the most lucrative branch of nursing anesthesia, and travel anesthetists can bring in upwards of $200,000 annually, depending on their location and experience level.
