A colleague shared this post about Bovine Lipid Extract Surfactant, a unique substance made up of fats and proteins found in the lungs of cattle. Most premature human babies are born without enough surfactant in their lung tissues to keep the tiny alveoli from collapsing. BLES works better than any synthetics to date. It has the ability to mimic the complex mixture of proteins and fats found in natural surfactant.
