3 Basic Operation
When connecting devices for acquiring measurements, always position cables and NBP tubing
carefully to avoid entanglement or potential strangulation.
A patient possibly wears transducers for long periods without interruption. In rare cases, skin
irritations may occur if a transducer is attached to one location for a longer period. To ensure there are
no adverse effects on the patient's skin, inspect the transducer application site at least every three
hours. If the skin quality changes, move the transducer to another site.
The ultrasound transducer is often repositioned to follow the fetal heart as part of the normal
monitoring process, but this is not so for the Toco transducer. Therefore, remember to check its
application site (between contractions) at least every three hours.
To reduce the risk of skin irritations, do not allow a cleaning or disinfecting agent to remain on the
transducer. Follow all instructions that accompany the specific cleaning and disinfecting agents you are
using. Remove agent residues with a cloth dampened in water before applying a transducer to a patient.
See "Care and Cleaning" on page 233 for further information, and a list of approved agents.
