What is the purpose of the entrainment port on a venturi mask?

Explanation:
Venturi masks deliver a precise oxygen concentration by mixing a fixed oxygen flow with room air through an entrainment port. That port pulls in ambient air and dilutes the oxygen so the patient receives the intended FiO2 rather than pure oxygen. The size of the entrainment port and the jet determine how much air is drawn in, which is how the device achieves a specific FiO2 independent of the patient’s breathing pattern within its design limits. It's not about increasing humidity, storing oxygen, or filtering exhaled gas.
