TABLE 4-1: RANGE FOR BLOOD PRESSURE TRANSDUCERS
PRODUCT CODE DESCRIPTION PRESSURE RANGE
UT-DPL-100 Digital blood/liquid pressure transducer -10 – 10 kPa (-75 – 75 mmHg)
UT-DPL-400 Digital blood/liquid pressure transducer -40 – 40 kPa (-300 – 300 mmHg)
To confirm whether or not a transducer is appropriate for a certain application, please contact
SCIREQ Technical Support.
To use the transducer, proceed as follows:
1) Attach a saline-filled syringe to the transducer via the three-way stopcock that is nearest to
the black box of the transducer.
2)
Orient the valve of the stopcock to isolate the transducer from the liquid.
3)
Fill the transducer chamber with physiological saline from the syringe, and ensure that
there are no air bubbles in the circuit.
4)
Orient the valve of the stopcock to isolate the syringe from the circuit.
5) Connect an arterial line to the other end of the circuit via the three-way stopcock furthest
from the black box of the transducer, and then open it to the transducer chamber. Keep the
entire transducer in a horizontal position near the subject while taking measurements.
Pressure measurements are displayed in real-time and may be recorded in the database.
4.1.5 AUXILIARY PRESSURE
SCIREQ offers a wide array of pressure sensors that are optimized to offer the highest
sensitivity for a given pressure range. Each sensor comprises a pressure sensing element that is
further linearized by a microprocessor. Use of auxiliary pressure transducers may be necessary
if you wish to record pressure in a location outside the module. Applications that use auxiliary
pressure transducer include use of negative pressure forced expirations and imaging, though
monitoring auxiliary pressure in the latter case is not required.
