DRAMIŃSKI BLUE – user manual
10.9.2. Registration of blood ow spectrum
To start recording the blood ow spectrum, select the [Gate Update] check box.
A leading line will appear at the bottom window, and then a diagram of hemodynamic blood parameters will
appear. At this stage it is important to hold the probe in the initial position.
10.9.3. Modication of the spectral graph
The user can modify the graph after measuring the ow spectrum.
To change the position of the baseline of the chart, hold your nger on it until its color turns green, and then
move it on the screen up or down.
[Range] - allows correcting the depth of the sampling gate in the event that the probe position changed dur-
ing the measurement. After changing the depth, the software will calculate the parameters depending on the
previously recorded spectrum, and the lead line will create a new graph;
[Gain] – to enable signal amplication;
[Reverse] – to change the orientation of the spectral plot in relation to the baseline;
10.9.4. Measurement in Pulse Wave Doppler mode
10.9.4.1. [HR] - Heart Rate
Put two markers on the spectrum graph selecting two full heart cycles.
Results given in bpm.
10.9.4.2. [AT] - acceleration time
Put two markers on the spectrum graph:
– rst one in the place where blood ow velocity value in nal phase of diastole is the lowest,
– second one in the place where blood ow velocity is the highest.
Results given in seconds.
10.9.4.3. [RI PI PSV EDV]
Calculate PSV (peak systolic velocity), end-diastolic velocity (EDV), average velocity (AVG), pulsation index (PI),
resistance index (RI) at a particular section.
Put two markers on the spectrum graph:
– rst one in the place where blood ow velocity is the highest,
– second one in the place where blood ow velocity value in nal phase of diastole is the lowest.
The device will automatically calculate above values.
10.9.4.4. [Doppler Point]
Calculates the ow velocity at any point.
