Note
Take care to ensure no air is trapped in any components of the fluid pathway. The monitoring
system must be totally air-free for maximum performance, i.e., optimal dynamic response.
G. PressurizetheI.V.solutionsourceto300mmHg.Closeclamponpressurecuff.
CAUTIONS
• Make certain the drip chamber does not completely fill during pressurization. Air should
remain in the drip chamber so that the continuous flush rate can be verified following a fast
flush.
• Pulling a vacuum to purge bubbles from the lines is not recommended. This practice may
entrain air or release air from solution. If the line is primed in a forward manner under
pressure, care must be taken to assure the maximum pressure specifications for the
transducer are not exceeded.
