The invention discloses an oxygen pressure monitoring prompter for a unit passenger oxygen supply system, and relates to the field of pressure detection. The oxygen pressure monitoring prompter for the unit passenger oxygen supply system comprises an oxygen supply device, a display device and an oxygen conveying device, wherein the oxygen supply device is provided with an oxygen inlet channel, an oxygen outlet channel, a piston channel communicated with the oxygen inlet channel and the oxygen outlet channel, a piston slidably arranged in the piston channel and a valve assembly arranged in the oxygen outlet channel; a display cavity and a display diaphragm dividing the display cavity into a first pressure cavity and a second pressure cavity are arranged in the display device, and the display diaphragm displays different colors when bearing pressure changes. The oxygen conveying device is provided with a first connecting channel communicated with the oxygen outlet channel and the first pressure cavity and a second connecting channel communicated with the oxygen outlet channel and the second pressure cavity; when the pressure in the oxygen inlet channel changes, the piston moves along the piston channel, and the display diaphragm displays different colors. According to the oxygen pressure monitoring prompter for the unit passenger oxygen supply system, a user can conveniently check the oxygen supply pressure.
