Oxymetazoline (Afrin) can be used to reduce Inflammation and swelling associated with allergies and upper respiratory infections. The mechanism of action of oxymetazoline is which of the following? O vasoconstriction O stimulates epithelial cell divislon O cnhances cilary motility O blocks MUCUS production All of the following enhance the movement of oxygen through the air- blood barrier EXCEPT for O the large surface area for gas exchange. O the fact that oxygen is small O the fact that the alveolar wall is thick. O the fact that oxygen is uncharged. O the fact that the diffusion gradient is high.
