| 摘要 |
The invention concerns a method for controlling a respiratory gas monitor device, which typically comprises at least one respiratory gas analyzer, a gas sampling line, a gas pump for sucking sample(s) of respiratory gas from said gas sampling line, a power supply and a processing unit, and a pressure sensor pressure-connected to said gas sampling line and electrical-signal-connected to said processing unit. A minimum value and a maximum value in a signal from the patient are detected by said processing unit, and a difference between said minimum value and said maximum value is calculated, and is compared with a predetermined threshold value. If said calculated difference is below said threshold value said pump is switched off or kept non-operating by said processing unit, and if over said threshold value said pump is switched on or kept operating by said processing unit. |
