The apparatus comprises a measuring tube having a proximal end for connecting to a patients nose and a distal end leading to the surrounding atmosphere, a measuring gate, flow measuring means for measuring air flow in the measuring tube, first pressure measuring means for measuring the pressure in the tube proximal end and second pressure measuring means for measuring the pressure at the measuring gate. According to the invention the apparatus comprises means for generating a sound signal in the tube proximal end, or means for generating a sound signal at the measuring gate and means for receiving sound signals in the tube proximal end. The invention further relates to a method for measuring the above mentioned pressure drop.
