|Negative Pressure||An isolation room used for infectious patients from which the air is constantly being extracted to result in slight negative pressure in the room compared with the outside corridor. Any bacteria coughed by the patient will then be extracted through a filter system rather then blowing into the corridor.|
|Necrosis||Cell death caused by caused by the progressive degradative action of enzymes.|
|Notification (denotification)||The process of informing the officer for public health (Consultant in Communicable Disease) that a patient has a notifiable infection. This is usually done by filling out an official form.|
A patient may be found to have been diagnosed incorrectly so that “denotification” is required. There is no official form for this so it is usually done by letter or telephone.
