Abstract: PROBLEM TO BE SOLVED: To prevent a decrease of a sectional area of a detector. SOLUTION: In a measurement detector D, and particularly in an apparatus for measuring a pressure and/or flow rate of a respiration gas of a patient, a medication is applied to a surface of a wall 2 of a flow path 1 in direct touch with a flow of the gas to be measured and/or a surface of a limiting element 3 so as to decrease a contact angle of the surface and a water drop or a liquid drop including water to be smaller than that without the medication.

Abstract: Measuring detector and system for the measurement of gas flow, especially for the measurement of the pressure and/or flow of a patient's respiratory gas. The surface of the wall (2) of a flow channel (1) and/or the surface of a restricting element (3), said surface being in direct contact with the gas flow to be measured, is provided with an agent for reducing the contact angle (&thetas;) of a water drop or a drop containing water to said surface in relation to the contact angle formed between a corresponding water drop and a corresponding surface not treated with such agent.
