Study Notes
Shock
- Hypovolemic shock is caused by decreased fluid volume due to:
- Massive bleeding or hemorrhage
- Severe burns and plasma loss
- Prolonged diarrhea, excessive sweating, or vomiting leading to water loss
- Hypovolemic shock leads to decreased venous return, cardiac output, and tissue perfusion
Cardiogenic Shock
- Caused by the heart's failure to pump sufficient blood
- Results in decreased cardiac output despite normal cardiac filling pressure
- Associated with:
- Myocardial infarction
- Arrhythmia
- Pulmonary embolism
Neurogenic Shock
- Occurs when the nervous system is damaged, e.g., spinal cord damage or overdose of certain drugs
- Results in vasodilation, insufficient blood supply, and reduced systemic blood pressure
- Caused by loss of neurogenic tone of blood vessels
Septic Shock
- Caused by gram-negative bacteria in the circulating blood
- Results in vasodilation, blood stasis, and depressed cardiac function
- Early signs include hyperventilation, warm and dry extremities
Anaphylactic Shock
- No additional information provided
Diabetic Coma
- Caused by extremely high blood sugar levels and low insulin production
- A medical emergency requiring prompt treatment
