Pericardial effusion occurs when there is an abnormal amount of fluid around the heart. The heart is normally surrounded by a thin membranous sac called the pericardium. The space between the pericardium and the muscle that is the heart is referred to as the pericardial space. Normal levels of pericardial fluid within the pericardial space are from 15 to 50 mL or about 1-3 tablespoons. An effusion, therefore, represents an abnormal accumulation of fluid in Continue Reading
The brain is responsible for higher motor and sensory functions. It requires a constant source of oxygen in order to continue its vital functions. When the flow of oxygen is interrupted, the consequences can be devastating. Severe injury can occur when the brain lacks the oxygen needed to continue functioning. A total lack of oxygen can be referred to as “anoxic” injury whereas a partial lack of flow can be referred to as “hypoxic” injury. Brain Continue Reading
