What is Septic Shock
Exaggerated immune response to a mircoorgnaism, casuing vasodilation. Main triggers are gram neg or postive bacteria
General Symptoms of Shock
Think of what you see with poor perfusion. The body is reacting too this, it doesnt care what type of shock
- Tachycardia
- Pale, clammy skin
- Dyspnea with decreased 02 sats
- Oliguria
- ALOC
Why do lactate levels rise in shock
Hypoxia, causes body to switch to anerobic metabolism of oxygen, raising lactic acid
General Nursing Interventions for Shock
- IV Fluids
- Monitor I/O
- Monitor LOC
- Monitor Labs (electrolytes, BG, lactate,)
- Cardiac Monitoring
- lower head of bed, elevate lower extremities
How does Pulmonary Congestion Happen in Cardiogenic Shock
Cardiogenic shock is typically a L sided heart injury, meaning blood cannot be adequately pumped out of the heart into the body, therefore it gets back up in the heart and eventually, all the way to the lungs
Sympathetic vs parasympathetic NS
S = constrict
P = relax and dilate
What is hypovolemic shock
Shock caused by fluid volume loss, causing decreased intravascular volume, then decreasing perfusion and venous return, then decreasing CO, causing vasoconstriciton and more vascular resistance
What is Anaphylactic Shock
- Hypersensitivity reaction occuring to repeat exposure to an allergen.
- IgE mediated.
- Excessive relase of cytokines cause vasodilation, increased cap permeability/poor perfusion/ and laryngospasm and brochonspasm.
Tx: epinephrine, maintain airway, elevate legs, bronchodilator, antihistamine, corticosteroids
What is cardiogenic shock
The impairment of the hearts ability to contract, therfore decreasing cardiac output and impairing tissue perfusion.
Some causes include:
- MI
- Valve disease
- HF
- cardiomyopathy
What is neurogenic shock
The disruption of the symapthic tone. (over parasympathetic). The intravasular fluid shifts to the periphery in response. Decreasing CO and perfusion.
Some causes include:
- Spinal injury
- Brian injury
- Spinal anaesthia
- Some medication (CNS depressant, opioids)
Clinical Features of neurogenic shock
- Hypotension
- BRADYCARDIC
- WARM DRY SKIN (high blood flow to periphery, warm at first but then cools when stagnant = HYPOTHERMIA
- weakness or paralysis (d/t injury)
What to do if water seal of chest tube breaks
- clamp
- cut away tube
- submerg into sterile water
- unclamp
- monitor for pulmonary embolism
- inform provider
*chest tube should only be clamped for 15 seconds without an order
Explain when and where a chest tube should or shoudnt bubble
Water seal chamber
- intermittent = good
- constant = bad
Suction chamber
- intermittent = bad
- constant = good
