47 Cards in this Set

  • Front
  • Back


Force or resistance against which the heart pumps

Anaphylactic Shock

Severe shock caused by an allergic reaction


Extreme, lie threatening, systemic allergic reaction that may include shock and respiratory failure


Swelling or enlargement of a part of an artery, resulting from weakening of the arterial wall

Autonomic Nervous System

Part of the nervous system that regulates involuntary activities of the body, such as heart rate, blood pressure, and digestion of food

Cardiac Tamponade

Compression of the heart as the result of buildup of blood or other fluid in the pericardial sac, leading to decreased cardiac output

Cardiogenic Shock

Sate in which not enough oxygen is delivered to the tissues of the body, caused by low output of blood from the heart. It can be a severe complication of a large acute myocardial infarction, as well as other conditions.

Compensated Shock

Early stage of chock, in which the body can still compensate for blood loss


Blue skin discoloration that is caused by a reduced level of oxygen in the blood

Decompensated shock

Late stage of shock when blood pressure is fallign


Loss of water from the tissues of the body

Distributive Shock

Condition that occurs when there is a widespread dilation of the small arterioles, small venules, or both.


Presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area


Balance of all systems in the body


Condition in which the internal body temperature falls below 95 F

Hypovolemic Shock

Shock caused by fluid or blood loss

Myocardial Contractility

Ability of the muscle to contract

Neurogenic Shock

Circulatory failure caused by paralysis of the nerves that control the size of the blood vessels, leading to widespread dilation; seen in patients with spinal cord injuries

Obstructive Shock

Shock that occurs when there is a block to blood flow in the heart or great vessels, causing an insufficient blood supply to the bodys tissues


Flow of blood through the body tissues and vessels

Pericardial Effusion

Collection of fluid between the pericardial dac and the myocardium


Precontraction pressure in the heart as the volume of blood builds up

Psychogenic Shock

Shock caused by a sudden temporary reduction in blood supply to the brain that causes fainting

Pulmonary Embolism

Blood clot that breaks off from a large vein and travels to the blood vessels of the lung, causing obstruction of blood flow

Pulse Pressure

Difference between the systolic and diastolic pressure


Developing a sensitivity to a substance that initially caused no allergic reaction

Septic Shock

Shock caused by severe infection usually bacterial


Condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion


Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening


Fainting spell or transient loss of consciousness

Blood flow through the capillary beds is regulated by:

the capillary sphincters

The autonomic nervous system regulates functions such as:


Regulation of blood flow is determined by

Cellular need

Patients in cardiogenic shock should not recieve


__________ develops when the heart muscle can no longer generate enough pressure to circulate the blood to all organs.

Cardiogenic shock

Neurogenic shock is caused by:

the radical change in the size of the vascular system

________ is a sudden reaction if the nervous system that produces temporary vascular dilation and fainting

Psychogenic shock

Causes, signs, symptoms, and treatment for Cardiogenic Shock

Causes: Inadequate heart function, disease pf muscle tissue, Impaired electrical system, disease or injury

Signs and Symptoms: Chest pain, irregular pulse, weak pulse, low bp, cyanosis, cool clammy skin, anxiety, crackles, pulmonary embolism

Treatment: Position comfortably, high flow oxygen, assist ventilations, transport properly, consider ALS.

Causes, signs, symptoms, and treatment for Obstructive Shock

Causes: Tension pneumothorax, cardiac tamponade, pulmonary embolism

Signs and Symptoms: Dyspnea, rapid weak pulse, rapid shallow breaths, decreased lung compliance, unilateral decreased or absent breath sounds, decreased blood pressure, jugular vein distension, cyanosis

Treatment: ALS assist and/or rapid transport, administer high flow oxygen

Causes, signs, symptoms, and treatment for Septic Shock

Causes: severe bacterial infection

Signs and Symptoms: Warm skin or fever, tachycardia, low bp

Treatment: transport properly, high flow oxygen, assist ventilation, keep patient warm, consider ALS

Causes, signs, symptoms, and treatment for Neurogenic Shock

Causes: Damaged cervical spine, which causes widespread blood vessel dilation

Signs and symptoms: bradycardia, low bp, signs of neck injury

Treatment: secure airway, spinal immobilization, assist ventilations, high flow oxygen, preserve body heat, transport promptly, consider ALS

Causes, signs, symptoms, and treatment for anaphylactic shock

Causes: extreme life threatening allergic reaction

Signs and Symptoms: Can develop within seconds, mild itching or rash, burning skin, vascular dilation, generalized edema, coma, rapid death

Treatment: manage airway, assist ventilations, high flow oxygen, determine cause, assist with epinephrine, transport promptly, consider ALS

Causes, signs, symptoms, and treatment for psychogenic shock

Causes: temporary generalized vascular dilation, anxiety, bad news, sight of injury or blood

Signs and Symptoms: rapid pulse, normal or low blood pulse

Treatment: Determine duration or unconsciousness, position patient supine, record initial vitals, suspect head injury if slow to regain consciousness, transport promptly.

Causes, signs, symptoms, and treatment for Hypovolemic shock

Cause: loss of blood or fluid

Signs and Symptoms: rapid, weak pulse, low blood pressure, change in mental status, cyanosis, cool clammy skin, increased respiratory rate

Treatment: secure airway, assist ventilations, administer high flow oxygen, control external bleeding, keep warm, transport promptly, consider ALS
