Abstract
A start-up ramp system for CPAP and bilevel CPAP devices. The system offers the patient a choice of at least two, time-pressure ramp paths over a predetermined, fixed, initial time interval to a predetermined, fixed, initial therapeutic pressure. Both the initial time period and initial therapeutic pressure are set by the care giver and are non-adjustable by the patient. In operation, the patient then selects the ramp path of his or her choice to the pre-set pressure over the pre-set time period by depressing an actuator button which has a graphic or pictorial representation of the ramp path on it. Regardless of the ramp path selected, the CPAP device will reach the predetermined therapeutic pressure only after the predetermined time interval set by the care giver has lapsed.
