Frequently Asked Questions (FAQ)
6. How to utilize ANSWatch for self monitoring or home tests?

There are various ways ANSWatch can help you  monitor and improve your health.
While you could design your own protocol creatively, follow the general rules below for
maximum benefit:
(1) Do not substitute professional instructions with self-interpretation. Test results of
blood pressures, heart rate variability (autonomic nervous system functions), and
irregular heartbeats should be analyzed by physicians or health professionals who
understand your health condition
(2) If you are currently taking medicine, consult with your doctor to determine the best
times for conducting blood pressure and heart rate variability tests. *Do not stop taking
or switch medicine without your doctor’s permission
(3) Efforts should be made to conduct tests under similar conditions at same time
zones of the day.  Avoid time periods of before meal, after meal, or after heavy
exercise.  Suggested time periods for testing are: 9 ~ 11:30 AM, 2 ~ 6 PM, and 8 ~ 10
PM.  Rest for at least 15 minutes between two consecutive tests
(4) If you are monitoring irregular heartbeats, you should conduct tests at different
time zones of the day to understand the frequency and severity of cardiac arrhythmias
throughout the day (for instance, first test right after getting up from bed, second test
at 10 AM,  third test at 2 PM, and last one before going to bed). Or, when you notice
palpitations, you can initiate a test right away
(5) To prepare for a test, remove any wearing (watch, jewelry, etc.) on the left wrist. Lie
down or sit comfortably for 10 minutes. When ready, wear ANSWatch on your left wrist
according to instructions in this User’s manual
(6) During the test, keep quiet and maintain stable. *No talking or body movement is
allowed. Close your eyes for better results. It has been noted that blood pressures
could be affected by muscle tightness or postural change. Autonomic nervous system
could also respond to environmental, physical, or mental disturbances
(7) Establish first the baselines of body parameters by consecutive tests at the same
time zone (morning, afternoon, or evening) for several days
(8) Continue to monitor. Ignore the occasional outliers (caused by cold, flu, or bad
sleep, etc.)
(9) Pay attention to any trendy change or deviation from the baseline. If the new trend
is in the direction of improvement, that means any action taken recently is working;
Conversely, if the change is towards worsening, consult with your physician
(10) ANSWatch offers the function of "Real-time test" to catch transitory effects.  HRV
and heart rate are reported every 10 sec during the test (max 20 minutes).  The
following are some examples of such effects:
 Deep breath (Qi practice): Inhale and exhale slowly and deeply (sitting or lying
down position; using the time clock on LCD  or PC to monitor); During practice, the
whole body is relaxed, real-time heart rate HR will go down and ANS total activity
index HRV will rise gradually.
 Music therapy (sitting or lying down): Let go any thought in mind, concentrate on
listening to music; same effect on HR and HRV as above
 Stand-up test: testing for 5-min using sitting position followed by standing up for 5-
min.  Note the difference of HR and HRV between two positions on LCD or PC.
Standing should have a higher HR and lower HRV than sitting, indicating healthy ANS
adjustment.
 Recovery rate after exercise: After heavy exercise, wear ANSWatch and start Real-
time test; As the body recovers, HR goes down slowly while HRV goes up. A fast HR
recovery (back to normal) indicates healthy ANS, heart, and circulation.
