It is considered hypotension, values of systolic blood pressure below 80 mmHg and mean arterial pressure below 60 mmHg which promote severe hypoperfusion, requiring emergency treatment (BOAG; HUGHES, 2005). Hypotension cases in animals are frequent and have various etiologies, this may be generated by sepsis, bleeding or cardiogenic shock, for example. The importance of the need for monitoring in critically ill patients arises from the possibility of hypoperfusion generated by hypotension, which can lead to multiple organ dysfunction, mainly affecting the kidneys and brain, sensitive organs to low oxygen. In addition, hypotension may precede the shock, and if not treated immediately and has a high mortality rate. The study will be made from hypotension identification in animals in the intensive monitoring service, assessing the main demographic characteristics, the main condition, the type of treatment provided, either, fluid or vasoactive agents and if there was responsiveness or not by dividing the animals at pre-determined groups according to the type of treatment. The analyzes will be carried out with the help with the tests Shapiro-Wilks, chi square and Fisher exact.
