Invasive blood pressure15-115 Invasive blood pressureSafety precautionsWarnings• All invasive procedures involve risks to the patient. Use aseptic technique. Follow cathetermanufacturer's instructions.• Make sure that no part of the patient connections touches any electrically conductivematerial including earth.• Mechanical shock to the invasive blood pressure transducer may cause severe shifts inzero balance and calibration, and cause erroneous readings.• When initializing the IBP parameter, Invasive blood pressure alarm activation criteria mayresult in inactive limit alarms.• When using the electrosurgery unit, ensure proper contact of the ESU return electrode tothe patient to avoid possible burns at monitor measurement sites. Also ensure that theESU return electrode is near the operating area.OverviewYou can measure and monitor two invasive blood pressures at the same time using a dualinvasive blood pressure cable. To measure invasive blood pressure you need the IBPconfiguration in monitor.To measure invasive blood pressure, a catheter is inserted into an artery or vein. The invasiveblood pressure setup, consisting of connecting tubing, a pressure transducer, and a fluidsource to maintain pressure (all connected together by stopcocks) is attached to the catheter.The transducer is placed at the same level with the heart, and is electrically zeroed. Thetransducer is a piezo-resistive device that converts the pressure signal to a voltage. Themonitor interprets the voltage signal so that pressure data and pressure waveforms can bedisplayed.The measured invasive blood pressure parameters are systolic, diastolic, and mean. Pulse ratecan be monitored with any arterial site. CPP is a calculated value that requires a valid ICP valueand a valid arterial site value. 2 channel pressures can be monitored.During the invasive blood pressure measurement, the transducer converts pressure variationsinto electrical signals. The electrical signals are amplified and displayed as numeric pressurevalues and waveforms.
