week 7 mix (shock/MODS) Flashcards
What are the factors influencing Blood pressure and cardiac output?
Preload, afterload, Contractility
What is afterload?
The pressure that must be overcome before the valve at the base of the aorta (semi-lunar) can open
What is shock?
Altered physiological state that can affect the functioning of every cell and organ system in the body. It is a complex syndrome reflecting decreased blood flow to body tissues, with resulting cellular dysfunction and eventual organ failure
What are the clinical features related to shock?
Pallor, cold/clammy, decreased peripheral perfusion, increased HR, decreased BP, increased RR
What is Hypovolaemic shock?
Refers to a loss of circulating blood volume, compensating mechanisms fail and causes a drop in CO and hypoperfusion
What is Cardiogenic shock?
Caused by failure of the heart to pump efficiently, low cardiac output results in poor perfusion.
What is Neurogenic Shock?
Results from the interruption of the autonomic nerve supply from the Central Nervous System. It reduces cardiac output and increases vasodilation
SIRS (Systemic Inflammatory Response Syndrome) is manifested by 2 or more of a number of symptoms, what are these?
Temp >38 or 90, RR >20 or PaCO2 12,000/cu mm or
Nursing treatment of Sepsis and septic shock
Implement management bundles, monitor pt, O2/ventilation, fluid replacement, vaso-active drugs (inotropes, vasopressors), AB’s, nutritional support, pt comfort
Describe Multiple Organ dysfunction Syndrome (MODS)?
Altered function in acutely ill patient requiring medical intervention to achieve homeostasis
Describe Multiple Organ dysfunction Syndrome (MODS)?
Altered function in acutely ill patient requiring medical intervention to achieve homeostasis
Nursing management of Anaphylactic shock?
Oxygen, IM adrenaline, Fluid replacement, Antihistamines: steroids
Define sepsis?
Clinical condition caused by overwhelming immune response to infection
What type of shock is septic shock?
Distributive shock
