WebSep 16, 2024 · The amount of CSF drainage depends on the pressure difference between the ICP and the height of the chamber; For example: EVD is set to 5 cmH 2 O: When ICP is greater than 5 cmH 2 O, CSF will flow into the lower pressure system (the EVD chamber). As such, a low setting like this facilitates drainage (as ICPs are often >5cmH 2 O).; EVD … WebA waveform was interpreted as abnormal if there was a flat or nearly flat waveform.
