M7 Immunity 2 Flashcards
MODS
Multiple organ distress syndrome
MODS is characterized by
failure of a t least 2 major organs
hemostasis cannot be achieved without intervention
SIRS leads to _ leads to
MODS
Shock
Causes for mods
Severe injury or illness
Muscle or tissue trauma
Shock
Which shock is most common with mods
Septic
MODS Patho
Uncontrolled inflammation
Vasodilation
Protein mediators leak into interstitial space
Coagulation cascade activates
Hypotension leads to decreased perfusion/micro emobli
this decreases flow to
Lungs
Kidneys
Heart
Liver
MODS leads to ARDs
Acute respiratory distress syndrome 101
Increased capillary permeability
Fluid moves from vessels to alveoli, edema
Surfactant decreases, alveoli collapse
ARDs is indicated by
VQ mismatch
Pulmonary hypertension
Increased resp rate
hypoxia

BP Drop
Increased HR
Increased permeability causes albumin to go into tissue with fluid
