Current concepts in thoracic drainage systems
Abstract:
Thoracic drainage systems are currently marketed in many varieties, resulting in significant cost and complicating patient management. Realistic needs have been identified from a survey of thoracic surgeons. These are: (1) clear plastic chest catheters with multiple drainage holes in sizes 28, 32, and 36F for adults and 16, 20, and 24F for infants and children; (2) serrated plastic connectors that can be sized at operation; (3) connecting tubes of clear plastic 6 feet long with a diameter of 1/2 inch; (4) a single graduated volume-collecting bottle of 1- to 2-liter capacity that can be emptied and marked, with a separate waterseal component and an associated manometer; and (5) a highflow vacuum source. A drainage system with these characteristics should be safe, effective, simple, and less costly.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
