Symptoms & Signs
There are two pathways leading to acute respiratory distress syndrome (ARDS): a direct (pulmonary) insult that directly affects lung parenchyma, and an indirect (extra pulmonary) insult that results from an acute systemic inflammatory response. In the latter case, it is majorly due to bacterial infection.
It is a multifactorial syndrome – the causative factors vary from patient to patient. Some of the known causes of ARDS can be:
- Sepsis (an overwhelming infection in the body)
- Aspiration of fumes, or chemicals
- Breathing vomit into the lungs (aspiration)
- Swelling in lungs
