Rest profile
The following results will be calculated for anal pressure profiles:
•
Length of anal zone.
•
Average internal sphincter pressure.
•
Pressure transmission ratios at transmission markers when these markers
are present.
•
Length of HPZ (High Pressure Zone). This is the profile area where the
pressures are higher than 50% of the maximum pressure.
•
Vector Volume.
•
Asymmetry index.
Length anal zone
The length of the anal profile is defined as the distance [C]. This distance is
measured in mm. It is calculated as the product of the puller speed and the
time between the marker [A] and the marker [B].
Average internal sphincter pressure in anal zone
The average internal sphincter pressure is defined as the average value of
anal pressure between the markers [A] and [B]. The pressure will be
calculated on the channel marked as IAS in the channel definition.
In the profile tables, the average for each distance is also calculated and
included in the table. In the results, a profile pressure table can be included.
This table displays the pressures for each channel over a certain distance of
the profile. In the result selection, this table can be activated or deactivated.
Squeeze profile
At this moment, only a profile pressure table can be included. This table
displays the pressures for each channel over a certain distance of the profile. It
is possible to display a 3D VVP for the squeeze profile. Vector Diagram can be
displayed for the profile when at least 3 channels are measured radial.
9.5.13 Balloon Expulsion Test
The balloon expulsion should be marked with two balloon expulsion
markers. The first balloon expulsion marker should be placed before
the expulsion of the balloon. The second marker should be
placed after the expulsion of the balloon. The balloon expulsion state (failed,
partial or success) will be displayed in the marker name.
Normally the markers are already placed during the investigation. You
can reposition the balloon expulsion markers, or insert new balloon
