After a pulmonary contusion, respiratory failure develops
overtime instead of immediately
Rib Fracture: There’s a risk that the rib could
puncture the lung
An injury to the 1st or 2nd rib
is esp bad
Management of uncomplicated rib fracture
you don’t have to do anything, it heals on its own.
flail chest: Chest movement is
opposite of what it should be (relative to breathing)
flail chest has a high ___ rate
morbidity
2 common causes of flail chest
car crash
CPR
flail chest: encourage pt to
DB and C
flail chest: give ___ O2
humidified O2
Pneumothorax
Air getting into the pleural space
Pneumothorax may or may not occur with some degree of
hemothorax
An open Pneumothorax is when there’s a wound starting from
the outside of the body, exposing the pleural space
A closed Pneumothorax example is
a person with COPD has a spontaneous tear
Pneumothorax: percussion would show
hyperresonance
In a closed Pneumothorax there is no where for the pressure to go so
it builds up an pushes the trachea in the other direction
Tension Pneumothorax involves
the lung collapsing
Tension Pneumothorax: When the pt breathes in, air gets in the the pleural space but
doesn’t get back out when they exhale
Tension Pneumothorax: pressure builds up in the pleural space and compresses
blood vessels, decreasing blood flow and therefore decreases CO.
Pneumothorax that’s an emergency
Tension
Under normal conditions, the U wave
may or may not be present
On the ECG, 1 second is represented by
5 big blocks
The T wave represents
vent repolarization
If the U wave is present it follows
the T wave
Sinus Arrhythmia means
HR goes up and down a little during breathing. Doesn’t necessarily mean there’s a problem
