Cal Signals

Viewing Patient Data

Inserting a The Mark Event function also enables you to insert a calibration Calibration reference into displayed waves.

Mark

When checking the magnitude of a displayed wave, it can be useful to

have a reference or standard to compare against. The key momentarily interrupts the displayed ECG, RESP, and pressure waves and inserts the cal pulse(s) for reference. (This calibration wave is in addition to the calibration reference bar that is always displayed on the ECG and RESP waves.)

Since these calibration pulses momentarily become the waveform signal, they are also communicated over the Philips monitoring network (SDN) and appear on system displays and recorders. The RS232 and analog output interfaces also carry these pulses.

If a recording is in progress, the calibration wave also appears on the recording (in addition to the recorder calibration wave at the start of the recording).
