Final answer:
The CPM machine is used postoperatively following a total knee arthroplasty to decrease the risk of complications like blood clots and joint stiffness. It promotes healing, increases blood flow, and prevents the formation of restrictive scar tissue. The CPM must be used as directed by the physician for the best outcomes.
Step-by-step explanation:
The Continuous Passive Motion (CPM) machine is used after a total knee arthroplasty, commonly known as knee replacement surgery, to mobilize the joint. The nurse recognizes that one of the benefits of using a CPM machine is indeed the decreased risk of postoperative complications, such as blood clots and joint stiffness. By moving the knee joint gently and continuously, the CPM aids in increasing blood flow, promoting healing, and preventing scar tissue formation which can lead to decreased range of motion. It is crucial that the CPM machine is used according to the physician's prescribed range of motion and duration to maximize its benefits.
Patients typically use the CPM machine soon after surgery, sometimes as early as the recovery room, and its use is generally recommended for several hours each day during the initial recovery period. It is an integral part of the post-operative care for knee arthroplasty patients, alongside measures such as physical therapy, medication management, and patient education on mobility and care.
