For points 1), 2), and 3), the measurement procedure is the same. In mercury

tonometer, do not forget to open the transport valve prior to the actual measurement, and to

close this valve again after the measurement.

After setting up the measurement apparatus, turn on the NIBP-1010 simulator and set

up the pressure measurement node to “MANOMETER” and proceed in accordance with the

user manual, Chapter “RUNNING AND TEST” on page 28 [1.7]. Close the air relief valve of

the ball and pressurize the system to the pressure of 200 mmHg. Then slowly relieve the

pressure and monitor the pressure values on the simulator, record the values measured on the

simulator and on the measuring tonometer in five points. In each measured point, close the

relief valve and wait for the pressure value on the simulator to settle. Adjust the size of the

pressure step to the number of measurements, and choose the pressure of 50 mmHg as the

lower limit. Record the measurement results in a table and mark them in a chart, where you

will project a calibration curve (a chart of deviations of the values measured as opposed to the

values on the NIBP-1010 pressure simulator) for each tonometer.

For points 4) and 5), the measurement procedure is the same. In point 4), do not

connect the ball, connect the tonometer directly to the pressure simulator, as the automatic

tonometer has its own pressure source.

Set up the measurement apparatus and turn on the NIBP-1010 simulator; set the NIBP

mode to simulation. Here you can choose from three situations - “Adult high”, “Adult low”,

and “Neonatal”. You will find a detailed description of the simulator’s set up in the user

manual, page 21, Chapter „BASIC TEST MODES“[1.7]. The parameters and the means of

controlling the digital tonometers are described in each tonometer’s user manual. Carry out

three measurements, each time with different situation. For each measured situation, record in

a table the simulated pressure values and the pulse rate from the simulator’s display and the

resulting measured pressure and pulse rate from the digital tonometer. Find out by calculation

whether the measured values are within the interval given by the particular tonometer’s

accuracy according to the manufacturer’s specifications. Record the measured values in a

table together with the calculated deviation.

With tonometers 1) - 3), carry out pressure measurement both with the palpation and

the auscultation methods, and compare the results with the automatic tonometer.
