Abstract:
The question of whether scuba diving is safe for patients with a history of venous thromboembolism (VTE) remains unanswered. Cases of VTE have been reported after decompression accidents but not following properly conducted dives. However, the risk of VTE and bleeding on anticoagulant therapy during diving has yet to be defined. Medical diving societies make different recommendations regarding the risk of scuba diving in patients with a history of VTE and/or hereditary thrombophilia and regarding the bleeding risk under anticoagulation associated with dives. There is no epidemiologic or pathophysiologic evidence described in the literature to support a direct association between VTE and diving. Therefore, VTE cannot be considered as a definite contraindication for scuba diving. Further studies are needed to conclusively establish the risk of VTE associated with diving and to guide the development of medical guidelines by diving societies.

Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above...
