Uterine Activity Monitoring: Intrauterine Pressure Monitoring (Internal Method)

Intrauterine Pressure Monitoring (Internal Method)

Methodology

Why Zeroing is Important

Revision D
A catheter inserted transcervically into the uterine cavity measures intrauterine
pressure. You can monitor using either a fluid-filled catheter or a transducer-tipped
catheter. The uterine activity value is displayed in mmHg from 0–100 and the trend
is continuously plotted on the bottom (or right) grid of the strip chart paper as a plain
black line.
Pressure exceeding 100 mmHg is printed as a straight line at
100 mmHg.
When you zero the system, you are referencing the pressure to
0 mmHg while the system is open to air to ensure an absolute pressure measurement.
