Aneurysm
A swelling or enlargement of part of an artery
Resulting from a weakening arterial wall
Autonomic Nervous System
Regulates involuntary things in body
sympathetic - Fight or flight
parasympathetic - Rest and Digest
Cardiac Temponade
Compression of heart due to build up of blood or fluid in pericardial sad
Decreased cardiac output
Cardiogenic Shock
Pump Failure
Compensated Shock
Early stages of shock. Body can handle it. Increased heart rate, pulse strong, pale skin, marked thirst
Cyanosis
Blue skin, reduced oxygen in skin, or decreased blood flow
Decompensated Shock
Systolic 90 or below. Late stage of shock. Body fails to compensate.
Pulse decreases, Drop in blood pressure, worsening LOC
Dilated pupils
Thready or absent peripheral pulses
Dehydration
Loss of water from the tissues of the body
Distributive Shock
Sepsis, Vessel Dialation of small arteries, small venules or both.
anaphylaxis
Pool Noodle, vessels too big
Edema
Large amounts of blood between cells and tissues. Causing swelling of area
Hypolemic Shock
Low blood volume from blood or plasma escape.
Low eletrolytes
Neurogenic Shock
Interuption of CNS, too big of vessels.
Normally won’t close below injury
Obstructive Shock
Mechanical interference with blood flow.
Can be Temponade blood in heart sac
Pericardial effusion
Collection of fluid between the paricardial sac and myocardium
Preload
Precontraction pressure in the heart as volume builds up
Psychogenic Shock
Syncope, Fainting, Fear
Temporary reduction in blood supply to brain
Pulmonary Embolism
Blood clot that breaks off from large vein and travels to blood vessels to lungs causing obstruction
Pulse pressure
Difference between systolic and diastolic
Systolic - Diastolic = Pulse Pressure
Sensitization
Developing sensitivity to substance that initially cuased no allergic reaction
Syncope
Fainting
Septic Shock
Caused by severe infection
Usually bacterial
Sphincters
Muscles that contract to constrict a duct, tube, or opening
Older Patients
Can’t deal with shock as well.
Take numerous medications that could mimic signs or shock
dentures airway obstruction
Alert for
Higher respiratory rates
Lower tidal volume
Decreased gag reflex
Treating Obstructive Shock
Pericardiocentesis Penetrating the pericardium with needle to draw blood from heart sac (ALS)
