IV Therapy: Tips, Care, and Complications
lms.rn.comTo briefly review the anatomy of a vein, you will likely recall that veins are highly distensible, thin‐walled vessels that transport blood back to the lungs and heart, and act as a volume reservoir for our circulatory system. Vein Anatomy Each vein is composed of three layers:

ntrs.nasa.gov3) Quantitative nondestructive testing methods used for flaw screening of thick-walled metallic structure are generally not applicable to COPV designs. Pressure vessels have historically been classified as failing due to either burst or leak-before-burst (LBB). These designations have been misleading in the past, suggesting that a vessel that is
