Afterload |
Force or resistance against which the heart pumps |
|
Anaphylactic Shock |
Severe shock caused by an allergic reaction |
|
Anaphylaxis |
Extreme, lie threatening, systemic allergic reaction that may include shock and respiratory failure |
|
Aneurysm |
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 |
|
Cyanosis |
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 |
|
Dehydration |
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. |
|
Edema |
Presence of abnormally large amounts of fluid between cells in body tissues, causing swelling of the affected area |
|
Homeostasis |
Balance of all systems in the body |
|
Hypothermia |
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 |
|
Perfusion |
Flow of blood through the body tissues and vessels |
|
Pericardial Effusion |
Collection of fluid between the pericardial dac and the myocardium |
|
Preload |
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 |
|
Sensitization |
Developing a sensitivity to a substance that initially caused no allergic reaction |
|
Septic Shock |
Shock caused by severe infection usually bacterial |
|
Shock |
Condition in which the circulatory system fails to provide sufficient circulation to enable every body part to perform its function; also called hypoperfusion |
|
Sphincters |
Circular muscles that encircle and, by contracting, constrict a duct, tube, or opening |
|
Syncope |
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: |
Disgestion |
|
Regulation of blood flow is determined by |
Cellular need |
|
Patients in cardiogenic shock should not recieve |
nitroglycerin |
|
__________ 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. |
