In medicine, not otherwise specified (NOS) is a subcategory in systems of disease/disorder classification such as ICD-9, ICD-10, or DSM-IV.It is generally used to note the presence of an illness where the symptoms presented were sufficient to make a general diagnosis, but where a specific diagnosis was not made.
Shock is divided into four main types based on the underlying cause: hypovolemic, cardiogenic, obstructive, and distributive shock. [2] Hypovolemic shock, also known as low volume shock, may be from bleeding, diarrhea, or vomiting. [1] Cardiogenic shock may be due to a heart attack or cardiac contusion. [1]
Hypovolemia, also known as volume depletion or volume contraction, is a state of abnormally low extracellular fluid in the body. [1] This may be due to either a loss of both salt and water or a decrease in blood volume. [2] [3] Hypovolemia refers to the loss of extracellular fluid and should not be confused with dehydration. [4]
Hypovolemic shock is a form of shock caused by severe hypovolemia (insufficient blood volume or extracellular fluid in the body). [ 1 ] [ 2 ] It can be caused by severe dehydration or blood loss . [ 3 ] [ 2 ] Hypovolemic shock is a medical emergency ; if left untreated, the insufficient blood flow can cause damage to organs , leading to ...
- anxiety - history of trauma to head or upper spine. - if the injury is to the head or neck, hoarseness or difficulty swallowing may occur. Symptoms of neurogenic shock are differentiated from other forms of shock by the lack of signs of the compensatory mechanisms triggered by the SNS, usual in other forms of shock.
One must also consider the possibility of multiple types of shock being present. For example, a trauma patient may be hypovolemic from blood loss. This patient could also have tension pneumothorax due to trauma to the chest. [22] Vital signs in obstructive shock may show hypotension, tachycardia, and/or hypoxia.
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation .
Hypotension, also known as low blood pressure, is a cardiovascular condition characterized by abnormally reduced blood pressure. [1] Blood pressure is the force of blood pushing against the walls of the arteries as the heart pumps out blood [2] and is indicated by two numbers, the systolic blood pressure (the top number) and the diastolic blood pressure (the bottom number), which are the ...
