Summary for Patent: 5,752,504
| Title: | System for monitoring therapy during calibration |
| Abstract: | A system for continuing the monitoring of certain gases delivered to a patient during the administration of nitric oxide to provide therapy to the patient. The nitric oxide is controlled by a electrically operated valve that is operated by means of an electrical signal from a CPU. At times when the various gas monitors are being calibrated, the normal alarms based upon those gas monitors are conventionally disabled during that calibration time. With the present invention, the electrical signal to the electrically operated valve is detected at the time the system goes into a calibration cycle and that detected electrical signal is used to establish limits such as a upper limit and a lower limit. Therefore, when the electrical signal to the valve is thereafter monitored and its value exceeds either of those limits, the overall nitric oxide delivery system will activate an alarm to alert the user of an abnormal condition. Thus an alarm system is present even when the various gas monitors are otherwise taken out of the system during their calibration. |
