Performing a Measurement

Performing a measurement is simple: while in a sitting position, open the

Finger Chamber Lid, insert your finger (see picture 3 in section measurement procedure), close the lid, and turn the screen towards you. The results will appear automatically. In order to start a new measurement follow the instructions set in paragraph 6 in the measurement procedure section and start from beginning.

Tips for performing a successful measurement

Keep in mind the following points while performing the measurement. It is explains in further detail in the Measurement procedure section.

Do not perform measurement when your finger is cold.

Page 27 of 78

 Do not perform measurement after physical exercise. Make sure your heartbeat is close to normal before performing a measurement.

 Relax while performing a measurement.

 You should be in a sitting position with your elbow resting on a firm surface.

 Your wrist should be relaxed and the arm extended.

 The device should hang on the finger downwards below the heart level

and slightly above the supporting surface. See Figure 2.

 Make sure that your fingernail clipped.

 If your fingertip is not intact, damaged or bandaged, use another finger

(either your ring or index finger).

Make sure the fingertip is clean and naturally moisturized.

Page 28 of 78

 Make sure that the lid of the Finger Chamber closed properly and that your finger is firmly in place.

 Check that a pulse waveform displayed. If not, try cleaning and reinserting your finger.

Figure 2: Measuring

Position

Page 29 of 78

Measurement procedure

1. Before performing a measurement, make sure your fingernail clipped and then clean your fingertip using the finger wipe provided with your TensorTip. Dry your finger. Performing a measurement on a dirty or greasy fingertip may affect the results.

2. Open the lid of the Finger Chamber by pushing the button. Do not attempt to

push your finger into the chamber

without opening the lid.

Page 30 of 78

3. While holding the TensorTip with your right hand, insert the index, middle or ring finger

(depending on which fits best) of your left hand with the bottom side of your finger in contact with the Chamber floor and touching the front of the Chamber. The fingertip should not be pushing the front of the chamber and should completely cover

the Chamber Lens (Figure 9).

4. Close the lid of the Finger Chamber.

Page 31 of 78

5. Turn your hand so that TensorTip is facing you. The device should be held slightly above the supporting surface at a position lower than your heart. Do not move or change position during the measurement.

6. TensorTip will automatically turn on and results will be shown within seconds. Open the lid and withdraw your finger to end the measurement. The device will then automatically turn off after 30 seconds if no buttons are pressed. The measurement can be stopped at any time by pressing the button.

Page 32 of 78

To abort the measurement and return to the Main Menu, press the button.

7. To switch between the parameters pages, press .

To switch between the graphical

displays modes, press .

Page 33 of 78

8. Remove and reinsert your finger to perform a new measurement.

Page 34 of 78

Caution

Do not try to force your finger into or out of the Finger Chamber as this will damage the seal and may affect the function of the device.

Make sure the device attached to your finger properly. If your finger is too small and does not fill the Finger Chamber, the device might fail to operate correctly.

Make sure the finger chamber lid closed properly. Do not force the lid on the finger if the finger is too large to fit in the chamber.

Page 35 of 78

 Important: Low blood perfusion in the fingertip may generate a weak signal, usually accompanied by the question mark as shown in the graph on the left picture (a), while picture (b) on the right represents a stable signal. The phenomena of low perfusion may occur when the fingertip is too cold. It suggested warming the fingertip in order to stimulate the blood circulation.

Picture (a) Picture (b)

 Note: low blood pressure or low Spo2 might be a result of low perfusion in the fingertip.

Page 36 of 78

 Warming the fingertip in order to stimulate the blood circulation can be achieved by casting your hand towards the ground, in this way larger amount of blood will flow to the fingers. In addition, you can rub your hands together.

Page 37 of 78

Interpreting your Graphs

Please note that the below graphs are for indication and description purposes only. The outline and scales of the graph will be as shown in below graphs.

 The following graphs represent the average value of the changes in the blood pressure over time. Picture 1 is to clarify the explanations.

 The blood pressure waveform is normalized between zero to

Max_Systolic_Amplitude. Therefore, blood pressure sloop decreases to zero

(scale value). Min Diastolic Amplitude scaled during each cycle to zero.

 Min_Diastolic_Amplitude > 0 (real value) since the blood volume in the blood vessels must be greater than zero otherwise the blood vessels would collapse. This basic volume of blood in the blood vessels generates the temporal average diastolic pressure.

Page 38 of 78

 The systolic amplitude decreases from Max_Systolic_Amplitude until reaching a point on the graph slope denoted by Min_Systolic_Amplitude. This point also represents the Max_Diastolic_amplitude. From that point the amplitude continues to decrease until reaching Min_Diastolic_Amplitude. This point is normalized to zero so the whole graph is scaled between zero to

Max_Systolic_Amplitude.

Picture (c)

Page 39 of 78

 Low perfusion of the blood in fingertip may have a disorder or low resolution waveform as in the following graphs (pictures (d), (e) and (f)) bellow. It is suggested to warm the fingertip by rubbing the fingertip.

Picture (d) Picture (e) Picture (f)

Page 40 of 78

 In cases of relatively high systolic blood pressure and relatively high diastolic blood pressure, the graph may be seen as in the following picture (g).

Relatively high systolic amplitude

Relatively high diastolic amplitude

Picture (g)

Page 41 of 78

 The following blood pressure waveform graphs (pictures (h) and (i)) may indicate that the stroke volume (or Cardiac Output) is relatively below normal.

Furthermore, picture (h) indicates that the diastolic pressure is relatively low while picture (i) indicates that the diastolic pressure is relatively normal. For more information, we suggest consulting your health physician.

Picture (h) Picture (i)

The Valsalva maneuver

The Valsalva maneuver performed by moderately forceful attempted exhalation against a closed airway, usually done by closing the mouth, pinching the nose shut while pressing out as if blowing up a balloon.

The normal physiological response consists of four phases.

1. Initial blood pressure rise with peripheral pulse descends.

On application of expiratory force, pressure rises inside the chest forcing blood out of the pulmonary circulation into the left atrium. This causes a mild rise in stroke volume.

2. Reduced venous return and compensation by pulse rate rise.

Return of systemic blood to the heart is impeded by the pressure inside the chest. The output of the heart reduced and stroke volume falls. This occurs from 5 to about 14 seconds in the illustration. The fall in stroke volume reflexively causes blood vessels to constrict with some rise in pressure (15 to

20 seconds). During this time, the pulse rate increases (compensatory tachycardia).

Page 43 of 78

3. Pressure release

The pressure on the chest released, allowing the pulmonary vessels and the aorta to re-expand. Venous blood can once more enter the chest and the heart, cardiac output begins to increase.

4. Return of cardiac output

Blood return to the heart is enhanced by the effect of entry of blood, which had been dammed back, causing a rapid increase in cardiac output (24 seconds on). The stroke volume usually rises above normal before returning to a normal level. With return of blood pressure, the pulse rate returns towards normal.

Deviation from this response pattern signifies either abnormal heart function or abnormal autonomic nervous control of the heart.

Page 44 of 78

Switching Between Display Modes

During measurement, as well as after the measurement has stopped, you can switch between the graphical display modes and between parameters pages. TensorTip can display graphs of either the FingerTip

ECG Waveform, the Blood Pressure Waveform (BPW), the Peripheral

Pulse Waveform (PPW) or the Blood Pressure Measurement Variation

(BP - Variation).

Accuracy

The Non Invasive TensorTip MTX is the first in the world that is capable of measuring Hemodynamic blood pressure without the use of air pumping. While performing the measurement you should be relaxed and avoid any movement. If the measurement fails, you may try inserting a different finger that best fits the chamber without excessive pressure on the fingertip.

The MTX has been assessed in correlation with automatic and manual

Sphygmomanometers and handheld oximeters in a study conducted on ambulatory volunteers. The precision of the MTX was compared between the closest value in the temporarily blood pressure interval and the reference measurement. The MTX standard deviation is relative to the standard deviation of the reference device:
