Nurses in today’s health care need cutting edge knowledge to effectively care for the complex needs of their patients. It is important for Perianesthesia care nurses to consistently evaluate their current practice to ensure that they are applying the most current evidence based practice rather than continuing care based on past methods. Capnography monitoring allows the perioperative RN to monitor respiratory status closely and accurately even before symptoms or desaturation of oxygen arises. Capnography provides earlier warning for impending depression, and can result in interventions, thereby providing a higher level of patient safety and potentially better outcomes.
