The article focuses on the use of peripheral venous access devices (VAD) for obtaining blood samples to measure activated partial thromboplastin times. VADs, also known as saline locks, have been in clinical use since the late 1970s. Historically, the device was used to provide emergency and intermittent venous access for patients who were receiving fluid, blood products, and nutritional support. One of the major advantage of using a peripheral VAD is that use of the device spares patients additional discomfort.
