Abstract
An apparatus for providing perceptible cueing signals to an expectant mother to which she may synchronize her breathing for the purpose of easing delivery includes an oscillator of selectable frequency and duty cycle which drives physiologically perceptible transducers. In the preferred embodiment, the transducers are two different colored lamps, one of which is illuminated to cue inhalation and the other to cue exhalation. The apparatus includes a manual start/stop switch depressed by the expectant mother at the beginning and end, respectively, of a contraction period to initiate and terminate the periodic display of inhalation and exhalation lamps. The apparatus includes an elapsed time indicator initiated by a stop signal and halted by a start signal which measures and displays the time interval between contractions.
