Hello all,
Welcome to Volume 1, Issue 12 of Alternativz. In the last
special edition, we described our initiative to reign in
essential hypertension, the form of high blood pressure
that the NIH and CDC offers “has no known etiology”.
Essential hypertension makes up 90-95% of all cases in
the US, affecting 60 million Americans and hundreds of
millions more around the world. High blood pressure and
its complications cost the US ~90 billon dollars in 2010.
We now have the first working model of the Figure 1: Stephen Elliott observing the respiratory
instrument that we are branding Heart Pro. We arterial pressure wave using a blood pressure cuff.
choose this name because it is ultimately the heart that gains the benefit of optimal breathing and bears the burden of suboptimal breathing – the heart has to work harder in the
absence of effective diaphragm movement. This is especially true for the right heart
which must vacuum venous blood back to the chest in the absence of effective inhalation.
Our thesis is that essential hypertension is caused by sub-optimal movement of the
diaphragm. When the diaphragm fails to move, it causes the circulation to slow. In traditional
Chinese medicine, this condition is referred to as “blood stagnation”. When the blood slows,
arterial blood fails to move with adequate flow and the autonomic nervous system increases pressure to facilitate more flow. It does this by increasing the power of the heart beat and by constricting
arteries. Alternatively, when we breathe with adequate depth and regularity, it facilitates circulation
and normalizes blood pressure. Conventional blood pressure measurement ignores this critical fact.
We intend to revolutionize blood pressure measurement by assessing the degree to which breathing is facilitating circulation, and instructing the user to breathe in a productive manner. We
do this by assessing the degree to which
breathing produces the wave, this wave being detected by a blood pressure cuff, along
with conventional systolic and diastolic
measures. This is in keeping with US patent #7458937, assessment of the respiratory
arterial pressure wave using oscillometry.
Figure 2 presents a working proof of
concept of the instrument. It detects

bottom panel being the pressure of the
heart beat which is modulated by breathing. In this example, cuff pressure is pumped up to
150mmHg and released over a period of approximately 60 seconds, during which we capture 4 cycles of Coherent Breathing, i.e. breathing at the nominal rate of 5 breaths per minute with comfortable depth. Systolic pressure is ~125mmHg; diastolic pressure is ~70mmHg.

Heart beat peaks and valleys are correlated with the known pressure of the cuff to determine dynamic
heart beat pressure as a function of breathing. In use, the instrument will present this variation to the
user in various simple formats, for example the
spoken words, “Your systolic pressure is normal. Your diastolic pressure is slightly higher
than what is recommended. Your breathing
is relatively rapid and shallow. It is recommended that you learn to breathe more slowly and deeply.” Quantitative results will also
be provided for user or health professional.

in the heart beat. This is what the heartbeat
pressure of the average breather looks like – little variation. Likewise, if we examine heart rate
variability (variation of the heartbeat in time), it also varies little.
Finally, here is another capture of the pressure when the cuff is at a resting pressure of ~40mmHg.
In the top panel we see “the wave” rising and falling during 5 cycles of Coherent Breathing. The heart beat (bottom panel) is rough due to the light pressure exerted by the cuff and
relatively poor transduction from the arm into the cuff.
We (the small development team) are very
pleased with the progress we have been able
to make over the last month. We consider
it a breakthrough that significantly changes our momentum and shortens the time it
will take in completing the prototype and
getting the final product to market.
Our next steps are to work out the measurement algorithms and certify their accuracy

such that we can report a highly accurate
measure of the wave. Paraphrasing Medical Physiology (Guyton & Hall 2002), “deep respiration”
can yield changes in the arterial pressure of up to 20 millimeters of mercury. During Coherent
Breathing, I believe that I have seen variations as high as 50mmHg. [Determination of systolic
and diastolic pressures via oscillometry is prior art.]

We continue to seek additional investors that would like to bring an end to essential hypertension and its health and financial consequences. We would like to thank those who have expressed interest or offered their financial support for this initiative.
Thank you for your interest, Stephen Elliott, President, COHERENCE LLC
