Question

Hemodynamics of anaphylaxis

Answer 1

Increased HR, CO Decreased BP, SVR (!), PCWP, CVP, PAP

Answer 2

Epinephrine Fluid resuscitation Racemic epinephrine for stridor Albuterol for wheezing ICS for inflammation

Answer 3

Systemic inflammatory response to an infection Decreased BP, SVR, PCWP, CVP, PAP Increased HR

Answer 4

Give antibiotics Remove sources of possible infection Give vasopressors Fluid resuscitation Antipyretics for fever as indicated

Answer 5

A short term treatment which provides aggressive form of life support for people with heart or lung failure (or both). The blood is oxygenated and CO2 is removed outside of the body through a membrane oxygenated It’s use is diminishing with the increase of HFJV, HFOV, or iNO

Answer 6

Veno-Arterial. Blood is drawn from the right atrium via the internal jugular vein Oxygenated blood is returned to the aortic arch via the right common carotid artery Typically used with cardiac failure or a bridge to a heart transplant

Answer 7

Veno-venous. Blood is removed from the right atrium from the right internal jugular vein Blood is returned to the right atrium via the femoral vein Used for acute respiratory failure or a bridge to lung transplant

Answer 8

OI >25 or P/F ratio <100 Failed conventional therapy methods Patient has a reversible disorder Patient has not suffered at ICH or stroke

Answer 9

ICH Clots Medication deposits in PVC tubing Bleeding secondary to heparin Infection Equipment related malfunctions

Answer 10

(Hb x 1.34 x SvO2) + (PvO2 x 0.003)

Answer 11

assumes 100% saturation in pulmonary capillary blood Used to calculate pulmonary shunting and evaluate oxygenation efficiency (Hb x 1.34 x 1.0) + (PAO2 x 0.003)

Answer 12

Low: Decreased O2 delivery or increased female (anemia, hypovolemia, low CO, hypoxia) High: Decreased Tissue O2 use (sedation, sepsis, hypothermia, shunting)

Answer 13

The arterial oxygen content reflects how much oxygen is available to the tissues (Hb x 1.34 x SaO2) + (PaO2 x 0.003)

Answer 14

Total oxygen delivery Normal: 900-1200 mL/min Decreases with low oxygenation low hemoglobin and decreased CO Increases with improved oxygenation, hemoglobin, or cardiac output

Answer 15

Represents the amount of oxygen extracted by the tissues Increased difference: Decreased cardiac output, or increased O2 Decreased difference: Increased CO, peripheral shunting, sepsis, hypothermia

Answer 16

Amount of oxygen used by the tissues each minute (oxygen uptake) Increased VO2: exercise, seizures, shivering, hyperthermia Decreased VO2: sedation, hypothermia, sepsis, cyanide toxicity

Answer 17

O2ER = (CaO2 - CvO2) / CaO2 x 100 Normal: 25% Indicates the proportion of delivered oxygen extracted by the tissues Increased: Low CO, anemia, increased metabolism Decreased: High CO, Sepsis, Hypothermia, cyanide toxicity

Answer 18

A shunt is the portion of cardiac output that moves from the right to the left heart without exposure to alveolar oxygen (PAO2) 1. Absolute (true) shunt 2. Capillary shunt 3. Relative shunt (shunt-like effect)

Answer 19

<10% normal 10-20% intrapulmonary shunting 20-30% significant disease >30% Life threatening
