ABSTRACT:
A system for the delivery of nitric oxide therapy to a patient that allows interventions by a user by activating a pause mode through a user input. A CPU in the system recognizes the activation of the pause mode and sends a signal to close a valve in order to discontinue the supply of nitric oxide to the patient. The activation of the pause mode also deactivates the normal alarm systems. A timer is activated when the system enters the pause mode and the timer allows a predetermined amount of time to pass while the pause mode is in effect. After that predetermined period of time has elapsed, the timer causes the CPU to reopen the valve to reestablish the flow of nitric oxide for the continued therapy and reestablish the alarm systems. The pause mode can be thus carried out without changing any alarm settings, established flows and the like so that the therapy is again recommenced at the same conditions as were in effect prior to the initiation of the pause mode.
