The surfactant addition further increased airflow because the surface tension in the alveoli decreased allowing the alveoli to expand more.

Not sure about the other one.

Thanks so much Duddy,

I know the second one has to do with a premature infant not having enough surfactant, but trying to find out the treatments, actually doing some research on that now.

Here is what I found:
The disease is mainly caused by a lack of a slippery, protective substance called surfactant, which helps the lungs inflate with air and keeps the air sacs from collapsing. This substance normally appears in fully developed lungs.

Treatments: A treatment called continuous positive airway pressure (CPAP) that delivers slightly pressurized air through the nose can help keep the airways open and may prevent the need for a breathing machine for many babies. Even with CPAP, oxygen and pressure will be reduced as soon as possible to prevent side effects associated with excessive oxygen or pressure
