A Cardiac CRNA (Certified Registered Nurse Anesthetist) is a specialized advanced practice nurse who provides anesthesia care for patients undergoing cardiac and thoracic surgeries. They work closely with anesthesiologists, surgeons, and other healthcare professionals to manage anesthesia before, during, and after procedures. Their responsibilities include administering anesthesia, monitoring patients' vital signs, managing pain, and ensuring patient stability. Cardiac CRNAs often work in hospitals, surgical centers, and cardiovascular units, requiring advanced skills in hemodynamic management and critical care.
