What are the inflammatory responses to shock?
SIRS
Which is a production of pro-inflammatory mediators,
histamine release, and capillary leakage
Inadvertent esophageal intubation assessment findings
include?
Gastric
distention,
absent breath
sounds,
minimal chest wall
movement and rapid
deterioration
,What is the normal PaCO2 and what does it measure?
Normal is 35-45 mmHg
It is the measurement of ventilation
Clinical assessment- rate, depth, and work of breathing
What is the normal PaO2 and what does it measure?
Normal is 80-100 mmHG
It is a measurement of diffusion
It reflects a problems with alveoli or pulmonary circulation
How do you calculate expected PaO2?
FIO2 x 5
If it's less than expected for a given FIO2, it is a diffusion
problem
What does of P:F ratio measure and how is it calculated?
It measures the extent of pulmonary shunting. It quantifies
the relationship between what goes into the lungs and
what gets into the blood.
PaO2/FiO2
What is a normal P:F ratio?
Normal is >450,
lower numbers are worse
,Patients who are very sensitive to supplemental oxygen are
telling us they have what type of problems?
It is a diffusion problem
What is DO2?
It is oxygen delivery.
It is impacted by
manipulating: SpO2,
Hgb, and CO
What is Vo2?
Oxygen consumption or use. (It is the difference between
the oxygen sent (SaO2) to the cells and the amount that
returns to the heart (SvO2) )
Normal VO2 is 180-280
Lactic acid is the marker of what?
Tissue ischemia -anaerobic
metabolism Normal serum
lactate is <2
Rib fractures cause a problem where is the cascade?
Ventilation- because it interferes with the mechanical process
of breathing
, Pulmonary contusion causes a problem where in the cascade?
Diffusion
Bruising and edema impair
gas exchange Best
parameter to measure is
P:F ration
What is the best parameter to measure diffusion?
P:F ratio
A simple pneumothorax presents a problems where in the
cascade?
Ventilation
Deflated section of the lung is not
participating in gas exchange An isolated
PTX can be treated with a CT in the 2nd
ICS
A tension pneuomothorax presents a problem where in the
cascade?
Ventilation & CO
Pulsus paradoxus and unilateral breath sounds
Needle thoracostomy is only appropriate for?
