Cardiogenic shock page 1719 |
Occurs when either systolic or diastolic dysfunction of the pumping action of the heart results in reduced cardiac output. |
|
|
Hypovolemic shock page 1719 |
Occurs when there is a loss of intravascular fluid volume. The volume is inadequate to fill the vascular space, the loss may be either an absolute or a relative volume loss. |
|
|
Multiple organ dysfunction syndrome page 1739 |
A failure of two or more organ systems in an acutely ill patient such that homeostasis cannot be maintained without intervention. |
|
|
Neurogenic shock page 1722 |
A hemodynamic phenomenon that can occur within 30 minutes of a spinal cord injury at eh first thoracic vertebra or above and last up to 6 weeks. The injury results in massive vasodilation without compensation due to the loss of the sympathetic nervous system vasoconstrictor tone. |
|
|
Obstructive shock page 1724 |
Develops when a physical obstruction to blood flow occurs with a decreased cardiac output. Can be caused by pulmonary embolism and thrombi. |
|
|
Sepsis page 1723 |
A system inflammatory response to a documented or suspected infection. Severe sepsis is defined as sepsis complicated by organ dysfunction. |
|
|
Septic shock page 1723 |
The presence of sepsis with hypotension despite fluid resuscitation along with the presence of inadequate tissue perfusion. The main organism that cause sepsis are gram-negative and gram-positive bacteria. |
|
|
Shock page 1717 |
A syndrome characterized by decreased tissue perfusion and impaired cellular metabolism |
|
|
Systemic inflammatory response syndrome page 1739 |
A systemic inflammatory response to a variety of insults, including infection, ischemia, infarction and injury. generalized inflammation in organs remote from the initial insult characterize SIRS. |
|
|
Anaphylactic shock page 1722 |
An acute and life threatening hypersensitivity (allergic) reaction to a sensitizing substance, (ex. drugs, chemical, vaccine, food, insect venom). usually an immediate reaction causes massive vasodilation, release of vasoactive mediators and increase in capillary permeability. |
|
|
Absolute hypovolemia |
Occurs when fluid is lost through hemorrhage, gastrointestinal(GI) loss, (example vomiting, diarrhea), fistula drainage, diabetes insipidus, or diuresis.
|
|
|
Relative hypovolemia |
Occurs when fluid volume moves out of the vascular space into the extravascular space |
|
|
SIRS |
Triggers that can cause SIRS - Mechanical tissue trauma - Abscess - Ischemic or necrotic tissue - Microbial invasion - Endotoxin release - Global perfusion deficits - Regional perfusion deficits |
