Site Map	Measure & Interpret a CVP Reading

• Introduce yourself and check the patient's identity
• Discuss procedure with the patient
• Identify mid-axillary reference point
• Using the spirit level, place the zero level of the manometer horizontal with the mid-axillary point
• Open three-way tap and fill the manometer to a level above the anticipated CVP
• Turn three-way tap to connect manometer directly to the central venous line
• The fluid level in the manometer will change and then stabilize at the level of the CVP.
  • Observe for variation in CVP with respiration
• Identify the CVP in cm H2O. Likley to be positive
• Document the reading in the patients records
• Turn three-way tap to close off the manometer line, re-connecting the infusion
• Discuss the result with supervisor
• State the value of the reading
