Making sense of underwater sealed drainage

Article Abstract:

Underwater sealed chest drainage aims to achieve optimum lung expansion. It may be necessary for lung re-inflation and removing air or fluid from the pleural space. One bottle is commonly used containing sufficient fluid to submerge the drainage tube. Nurses should check for air bubbles or fluid swinging to establish effective operation of the system. They should measure drained fluid. Nurses should also take precautions against disconnection, and contamination. A chest x-ray will establish lung expansion after drain removal.

Making sense of blood groups

Article Abstract:

ABO and rhesus are the most common blood grouping systems. The rhesus factor operates in addition to the ABO grouping. Blood group O predominates in the UK and about 85% of people are rhesus positive. Red blood cells of groups A and B contain antigens therefore blood is only suitable for the same group type. Group O red cells contain no antigens and is therefore universally suitable for donation.
