Abstract: An infant respiratory monitor for alerting the supervisors of an infant when there is a lack of movement of the infant due to potential respiratory problems. The device comprises a housing having an attachment for clip for securing the housing to an infant. Respiratory monitoring circuitry is contained within the housing, and comprises a power source which is in circuit with a motion sensor, processor and audio output means. The motion sensor detects movement, and transmits the presence of such movement to the processor. The processor is configured to count the number of signals received from the motion sensor within a pre-determined time period and alert the sound output means in the event that the number of signals received within the pre-determined period of time from the motion sensor drops below a pre-determined value. Upon that occurrence, the processor signals the audio output means to emit an audible alert warning noise.
