2.4 PulseScan (Pulse Arrhythmia) Technology
PulseScan (ARR) technology specifically detects the existence of pulse arrhythmia, including Atrial
Fibrillation (AFib), Atrial and / or Ventricular Premature Contractions (PC), Tachycardia (TACH),
and Bradycardia (BRAD). Pulse Arrhythmia may be related to cardiac disorders, needs medical
attention and thus early diagnosis is of paramount importance. The PulseScan technology detects
arrhythmia during regular blood pressure checks without any additional user skills, user interaction
and measurement prolongation. Beside the blood pressure diagnosis a specific pulse arrhythmia
diagnosis is provided with PulseScan.
Note: PulseScan screens for AFib, PC, TACH and BRAD is provided with a clinically proven high
detection probability [1]. However, the sensitivity and specificity is limited, thus most, but
not all pulse arrhythmia will be detected and displayed. In certain patients with uncommon
clinical conditions the PulseScan technology may not be able to detect pulse arrhythmia.
This partly comes from the fact that some arrhythmia can only be found with an ECG
diagnosis, but not with a pulse diagnosis. Thus PulseScan is not meant to replace any
medical ECG diagnosis by your doctor. PulseScan provides an early detection of certain
pulse arrhythmia, which inevitably need to be presented to your doctor in charge. Remark:
[1] Clinical Investigation of PulseScan - A new Oscillometric Pulse Arrhythmia Type
Discriminating Detection Technology
2.5 Atrial Fibrillation Detection (AFib)
The upper chambers of the heart (the atria) do not contract, but quiver and thus blood is driven
irregularly and with lower efficiency into the ventricles. Subsequently irregular heartbeats occur,
which mostly are associated with a fast, yet highly instable heart rate. This condition is associated
with a higher risk for the formation of cardiac blood clots. Amongst others, they may elevate the
risk of brain strokes. Beside this Atrial Fibrillation may contribute to the severity of a chronic or
acute heart failure condition and may be associated with other heart-related complications. Age
dependent, about 10%- 20% of patients who suffer from an ischemic stroke also suffer from Atrial
Fibrillation.
Atrial Fibrillation most often initially occurs with temporary periods of arrhythmia and may progress
to a permanent state of this disorder in the course of time. No matter, whether you intent to
safeguard yourself from an undetected AFib state, or you measure during an ongoing period of
active Atrial Fibrillation, or you measure in between periods of AFib, the PulseScan technology can
be applied at any of these conditions. This unit is able to detect Atrial Fibrillation AFib. The ARR
and AFib icons are displayed right after the measurement if Atrial Fibrillation was detected.
Note: It is strongly recommended, that you consult your physician, if either the AFib icon occurs
several times, or, if your AFib is known to your doctor, but the incidence of AFib readings
changes over time. Your doctor will then be able to provide all required medical test and
possible therapeutic procedures.
Note: The presence of a cardiac pacemaker may impair the AFib detection by PulseScan.
9
2.6 Premature Contraction Detection (PC)
Extra abnormal heartbeats generated in irregular excitation sites of your heart, either in the atria
(PAC), the ventricle (PVC) or the cardiac conduction nodes (PNC). These extra beats may disrupt
the regular rhythm, they may come in early or cause a significant pause regarding your perceivable
pulse. This is called palpitations, which can be felt in your chest. They may occur as isolated, single
events, as a series of irregular pulses or can be distributed all over your pulse beats. If they are not
related to mental stress, or acute demanding physical load, they may be a marker for a multitude
of cardiac disorders. Some of these disorders go along with an elevated risk profile for ischemic
events, either in the heart (e,g, coronary heart disease) or outside the heart, e.g. an elevated risk
for a stroke. Some PCs may indicate on valvular or myocardial disorders and become very important
if a myocarditis (infection of the heart muscle) is suspected. This unit is able to detect premature
contractions (PC). The ARR and PC icons are displayed right after the measurement if premature
contractions have been detected.
NOTE: It is strongly recommended, that you consult your physician, if either the PC icon occurs
several times, or, if your PC is known to your doctor, but the incidence of PC readings changes over
time. Your doctor will then be able to provide all required medical test and possible therapeutic
procedures.
2.7 Tachycardia Detection (TACH)
A fast heart rate of higher than 100 beats per minute (bpm) in adults. Unless being caused by
physical or mental stress, a tachycardia may be an indicator for both cardiac (e.g. Coronary heart
disease, valvular disorder), or extra-cardiac disorders (e.g. hyperthyroidism, fever, hypoxemia),
as well as medication and stimulant substance side effects (e.g. caffeine). The unit is able to
detect Tachycardia (TACH). The ARR and TACH icons are displayed right after the measurement if
tachycardia has been detected.
NOTE: It is strongly recommended, that you consult your physician, if either the TACH icon occurs
several times, or, if your TACH is known to your doctor, but the incidence of TACH readings changes
over time. Your doctor will then be able to provide all required medical test and possible therapeutic
procedures.
2.8 Bradycardia Detection (BRAD)
A slow heart rate of less than 55 beats per minute (bpm) in adults. Unless not genetically
determined or subsequent to a high cardiac endurance training adaptation, bradycardia may be
related to multitude of cardiac disorders (e.g. valvular heart disease, heart failure) or extracardiac
disorders (e.g. hypothyroidism, electrolyte imbalance) or medications (e.g. beta-receptor blocker).
This unit is able to detect Bradycardia (BRAD). The ARR and BRAD icons are displayed right after
the measurement if bradycardia was detected.
10
NOTE: It is strongly recommended, that you consult your physician, if either the BRAD icon occurs
several times, or, if your BRAD is known to your doctor, but the incidence of BRAD readings changes
over time. Your doctor will then be able to provide all required medical test and possible therapeutic
procedures.
2.9 Pulse Arrhythmia Detection (ARR)
Once the occurrence of pulse arrhythmia has been detected in the course of your blood pressure
measurement, the icon ARR is displayed. In the case, that the found pulse arrhythmia can be
specified by the PulseScan technology, the ARR icon is accompanied by the specifically detected
type of arrhythmia, e.g. PC, AFib, TACH or BRAD. If the kind of found pulse arrhythmia cannot be
determined by PulseScan, the device is displaying ARR without any additional pulse arrhythmia
type icon.
The PulseScan technology is able to detect and display combined pulse arrhythmia findings.
NOTE: It is strongly recommended, that you consult your physician, if either the ARR icon occurs
several times, or, if your ARR is known to your doctor, but the incidence of ARR readings changes
over time. Your doctor will then be able to provide all required medical test and possible therapeutic
procedures.

3.3 Obtaining Accurate Measurements
Blood pressure can vary based on numerous factors, physiological conditions, and surroundings.
Follow these guidelines to obtain accurate and error-free measurements of your blood pressure and
pulse rate.
14
3.3A Tips on Taking Accurate Measurements
In morning before breakfast, 2
hours after dinner, before taking
medication.
Avoid coffee and smoking within the
hour, and no exercise 30 minutes
before measuring.
Empty bladder (if necessary).
Rest quietly for 5 minutes.
Remain calm and quiet while the
measurement is in process.
Do not speak while taking the
measurement.
Sit with legs uncrossed so as not to
restrict blood flow.
Ensure that the BP monitor is level
with the heart while the arm is
supported on the table.
Take measurements on the non
dominant arm.
Sit with back supported and
measurement arm resting on a table.
Sit with feet flat on the floor.
3.3B Common Sources of Error
All efforts by the patient to support the arm can increase the blood pressure. Make sure the patient
is in a comfortable, relaxed position and is not activating any of the muscles in the measurement
arm during the measurement. Use a cushion for support if necessary.
ATTENTION!
Comparable blood pressure measurements always require the same conditions with a peaceful
and calm environment. Ensure that you take measurements under the same conditions to obtain an
accurate estimate of blood pressure variation patterns.
• If the arm artery lies considerably lower or higher than the heart, an erroneous value of blood
pressure is measured. Each 15 cm difference in height results in a measurement error of 10
mmHg.
• A loose cuff causes false measurement values.
• With repeated measurements, blood accumulates in the arm, which can lead to false results.
Consecutive blood pressure measurements should be repeated after at least a 15 second
pause or after the arm has been held up in order to allow the accumulated blood to flow away.

24 - 36 cm
(9.4” - 14.2”)
16 - 26 cm
(6.3” - 10.2”)
Index Line
b) Connect the air tube securely.
• Connect the air tube to the main unit by securing the air plug to the base of the air connector.
• Securely connect the air tube and the cuff set by rotating Luer connector.
16
c) Place the cuff around the patients bare arm. Make sure
the bottom edge of the cuff is about 1” (2-3 cm) above
the elbow joint. Adjust the cuff so that the rubber
tubing under the cuff lies over the brachial artery,
which runs on the inside of the arm (see Fig. c).
d) Pull the cuff and tighten it by attaching the Velcro®
fastener. Measure on the non-dominant arm, unless
there is a >10 mmHg difference with the other arm, in
which case use the arm with the higher pressure.
e) The cuff should fit snugly around the arm, but not too
tight. You should be able to fit two fingers under the
cuff. If the cuff is the wrong size, the deivce will not
measure blood pressure accurately.
c)
d)
e)
f) Place the arm on the table (palm facing upwards) so
that the cuff is at the same level as the heart. Make
sure there is no kink in the hose.
f)
17
g) You can adjust the level of the arm by putting a
cushion under the arm. Ideally the cuff should be at
heart level.
h) Remain seated in a comfortable room temperature for
at least 5 minutes, then start the measurement.
i) If this device was stored in low temperature, it is necessary to leave it in room temperature for
at least 1 hour, otherwise the measurement can be inaccurate.
Comment:
Continue to use the same arm for comparisons. It is not unusual for there to be a difference in
blood pressure between arms.
Comparable blood pressure measurements always require the same conditions (Relax for several
minutes before taking a measurement).
ATTENTION: Do not use cuffs other than the original cuffs contained in this kit!
