The present disclosure relates to a medical pressure measuring device (100) for measuring a pressure of a pressurized breathing gas supplied to a subject by a breathing apparatus (200). The device (100) comprises a pressure sensor (110) arranged at a point of measurement (195) and configured to measure the pressure of a sample gas at a sampling point (190).The sampling point (190) and the point of measurement (195) are connected by a pressure sampling tube (180) in which a pressure wave of the sample gas can propagate from the sampling point (190) to the point of measurement (195).The pressure sampling tube (180) has a sampling tube volume and an acoustic impedance. The medical pressure measuring device (100)further comprises a damping arrangement (120) arranged to be brought into fluid communication with the pressure sampling tube (180).The damping arrangement (120) comprises a flow restrictor (130) and a receptor chamber arrangement (140). The receptor chamber arrangement (140)comprises a receptor chamber (141). The receptor chamber arrangement (140)is an arrangement for receiving the pressure wave of the sample gas. The flow restrictor (130) correlates to the acoustic impedance of the pressure sampling tube (180) so as to prevent acoustic resonance in the pressure sampling tube (180). The receptor chamber (141) correlates at least to the volume of the pressure sampling tube (180), so as to prevent acoustic resonance in the pressure sampling tube (180).La présente invention concerne un dispositif (100) médical de mesure de pression pour mesurer une pression d'un gaz respiratoire sous pression fourni à un sujet par un appareil respiratoire (200). Le dispositif (100) comprend un capteur de pression (110) agencé au niveau d'un point de mesure (195) et configuré pour mesurer la pression d'un gaz échantillon au niveau d'un point d'échantillonnage (190). Le point d'échantillonnage (190) et le point de mesure (195) sont reliés par un tube d'échantillonnage de pression (1
