Pathophysiology

A disease that affects nearly 190,000
people annually in the United States Alone

-American Heart Association 2007
Approximately 25 percent to 40 percent of ARDS cases are fatal,
which is a huge improvement since the 50-70% just 20 years ago
So What does it look like?
Day 1
Day 2
Day 3
So in the matter of only THREE days a person can go into FULL ARDS
That leaves very little time for us, as health care providers to take action
So what are the
Signs and Symptoms?
* slight increase in heart rate and resp. rate
*Restlessness
*Shallow Rapid Breathing
*Crackling/wheezing
*Decreasing PaO2 despite O2 therapy

1. Pulmonary Edema

2. Atelectasis

Leaky Capillaries
Decreased Surfactant
3. Fibrosis
Associated with the inflammatory
deposition of proteins
Causes the lungs to stiffen
Together:
These cause stiff and non-compliant lungs
and protein filled fluid in alveoli

Atelectasis and pulmonary edema lead
to pulmonary shunting
So what causes it:
Primary Causes:
*Trauma
*Shock
*Sepsis
