Survival and Mortality (death)?
The mortality (death) rate estimates range from 30 percent to 70
percent. Recent data suggests that on average more than 40 percent die from ARDS.
This data accounts for direct deaths resulting from not recovering from ARDS.
The data does not account for deaths among survivors which may be causally related
due to medical conditions arising or effected by the encounter with ARDS.
Since ARDS was first described in 1967, the prognosis has improved
slightly despite rapid advancements in medical science and technology. Statistical
data reveals that approximately one half of who develop ARDS each year will survive in the
United States and other countries which have well trained medical personnel and facilities
for treating ARDS patients.
Younger people and those who have fewer chronic health problems are
more likely to recover. It is known that people with a milder form of ARDS tend to
have a better chance of recovering than those with a more severe form of the illness.
It is also known that the cause of a patient's ARDS helps predict
that patient's chances for survival. For example, patients who develop ARDS due to
sepsis usually do not do as well as patients whose ARDS is related to trauma.
Finally, those patients who do survive after developing ARDS usually improve over several
months with a return to normal or near normal lung function.
