A respiratory mask apparatus (110, 20) having a ventilation control device (200) comprising: a cavity (210) comprising an air inlet port (211), an air outlet port (212), a mask ventilation port (213) in communication with the respiratory mask apparatus (110, 20) an air inlet valve (220) arranged at the air inlet port (211) and configured to open when the pressure inside the cavity (210) is less than or equal to the atmospheric pressure and an air outlet valve (230, 330, 430, 530) arranged at the air outlet port (212) and configured to open when the difference between the pressure inside the cavity (210) and the atmospheric pressure is greater than or equal to a first predefined value. The ventilation control device (200) has the function of providing positive airway pressure during an exhalation phase, preventing patient discomfort resulting from continuous positive airway pressure (CPAP). In operation, it is not required to connect the ventilation control device (200) to a positive airway pressure supply device (130) (such as a CPAP respirator) and a tube (120), and therefore facilitates patient movement. Since it is not required to carry the positive airway pressure supply device (130) when going out, a patient can wear the respiratory mask apparatus (110, 20) comprising the ventilation control device (200) anytime for treatment. Furthermore, the ventilation control device (200) is compact in size, easy to carry, and low in cost.La présente invention concerne un appareil de masque respiratoire (110, 20) ayant un dispositif de commande de ventilation dair (200) comprenant : une cavité (210) comportant un orifice dentrée dair (211), un orifice de sortie dair (212), un orifice de communication dair de masque (213) conçu pour communiquer avec lappareil de masque respiratoire (110, 20) une soupape dentrée dair (220) disposée au niveau de lorifice dentrée dair (211), et comprenant une structure conçue pour être ouverte lorsquune pression à lintérieur de la cavité (210)
