Who made the recommendations to record vital signs every 5 minutes after surgery?

The recommendations to record vital signs every 5 minutes after surgery typically come from guidelines set by surgical and anesthesia societies, such as the American Society of Anesthesiologists (ASA) and the American College of Surgeons (ACS). These guidelines are based on clinical evidence aimed at ensuring patient safety and early detection of complications in the postoperative period. Specific protocols may vary by institution and type of surgery, but the overarching goal is to monitor patients closely during recovery.
