Patient Evaluation and Preparation Flashcards
Oxygenation
refers to the gas exchange and the amount of O2 in the arterial blood
Ventilation
the act of moving air in and out - removes CO2 from the body
Capillary Refill Time
Time taken for color to return after gentle press
Indicator peripheral perfusion
What is normal Capillary Refill Time?
1-2 seconds
What does a >2sec Capillary Refill Time indicate?
decreased peripheral perfusion, associated with shock and dehydration
Normal Mucus Membrane Color
Pink and moist
Pale Mucus Membrane Color
Anemia, vasoconstriction, hypovolemia
Brick red Mucus Membrane Color
Hyperdynamic status
Yellow Mucus Membrane Color
Icterus, hyperbilirubinemia
Petechial Bleeding
Thrombocytopenia, thrombocytopathy
Cyanosis
Hypoxemia
ASA I
Healthy animal, no systemic disease
ASA II
Mild Systemic disease
ASA III
Moderate or severe systemic disease
ASA IV
Severe systemic disease that is a constant threat to life
ASA V
Moribund patient that is not expected to survive 24 hours with or without surgery
E
Emergency
Indications for pre-anesthetic fasting
Decrease food and fluid in stomach
Decrease risk of aspiration
Distended stomach impairs ventilation and gas exchange
Reflux
open lower esophageal sphincter , gastric content enters the esophagus
Regurgitation
passive discharge of gastric content from the mouth
Vomiting
active process (projectile)
