Ch 8 Shock Flashcards
Shock
State of inadequate perfusion (flow of blood that carries O2 & nutrients, and takes away C02 & toxins) of the cells.
RTC - primary survey
Cell function stops
Cells die
Tissue dies
Organs die
Body dies
Hypoxia
Low oxygen
Initial Sign of shock
Blue tinge
Acidosis
Accumulation of acids
Result of shock
Perfusion
Flow of blood into & out of cells
Causes of shock
Hypovolemic insufficient blood volume
(Blood loss, fluid loss-burns, vomit, diarrhea)
Cardiogenic shock - myocardial infarction (heart failure)
Excessive blood vessel dilation - anaphylactic shock (allergy), septic shock (infection), neurologenic shock (spinal)
Lack of air will increase damage
Hypovolemic Shock
Shock due to inadequate blood circulation- blood or fluid (burns, vomit, diarrhea)
Cool skin
pale
Sweating
Increased heart rate (100+)
Low blood pressure (hypotension)
Altered LOC
Tachypnea (increased respiratory rate, 30+)
Thirst
Anaphylactic Shock
Shock due to Allergic reaction
Blood vessels dilate excessively
Do they have medic alert?
Do they have an epi pen?
Body reaction to shock
Reduction in cardiac = reduction in systolic pressure (max pressure)= triggers nervous system = adrenaline & noradrenaline
Increase heart rate
Vasoconstriction to non vital organs
Sweating (diaphoresis)
Special care patients for shock
Athletes- may not show altered heart rate and signs right away
Pregnant women - may not show shock, may be hurting fetus
Cardiac patients- high risk, medications may hide signs
Signs of anaphylactic shock
Medic alert bracelet/tattoo
Itching
Numbness & tingling - esp face and mouth
Blotchy/red-pink swelling (hives)
Swelling of tongue or face
Tightness in throat or upper airway
Difficultly breathing - wheezing
Tight across the chest
Weaknesses, restlessness, dizziness, anxiety
Also moral cramps, diarrhea, vomiting
Rapid, weak pulse
Epi pen
Is it expired?
10 sec in, 30 seconds rub
If expired 20 seconds in
Note time administered, keep the pen
Apply second dose if symptoms persist
