CmH2O

The title of this article is incorrect because of technical limitations. The correct title is cmH₂O .

cmH₂O is a somewhat outdated unit for pressure. It is used to measure the central venous pressure, the intracranial pressure while sampling cerebrospinal fluid, as well as determining pressures during mechanical ventilation.

It is defined as the pressure exerted by a column of water of 1 cm in height at 4 °C at the standard acceleration of gravity.

To convert this measure to other units, the following conversion is used:

1 mmHg = 1.36 cmH₂O = 0.133 kPa = 0.0193 PSI = 1.3332 mbar
