How to measure CVP (Central Venous Pressure)
It can be measured using an indwelling central venous catheter and either manually using a pressure manometer or electronically using a transducer. Usually, the manometer is used especially in wards. But in both ways, it must be ‘zeroed’ at the level of the right atrium. You may do this by taking it at level of the 4th intercostal space in the mid-axillary line while the patient is lying supine, each time at the same zero position.
