What Researchers Did
Researchers reviewed current knowledge about how stress changes in respiratory system tissues over time, a phenomenon known as stress-relaxation.
What They Found
They found that respiratory tissues, due to their elastic properties, do not hold constant stress under constant stretch; instead, the stress gradually decreases to a lower value. Various factors, including body temperature, inflammation, and hyperbaric oxygen exposure, affect this stress-relaxation. Understanding these effects is important because high inspiratory pressure, influenced by tissue elasticity, can increase the risk of respiratory failure.

Study Limitations
The review highlights that the precise molecular mechanisms behind stress-relaxation in respiratory tissues are still not fully understood.
