POTENTIAL FOR RADIO AND TELEVISION INTERFERENCE
This equipment generates and uses radio frequency energy and if not installed
and used properly, that is, in strict accordance with the manufacturer’s instruc-
tions, may cause interference with radio and television reception. It has been
tested, together with a certified Class B computing device Personal Computer,
in accordance with the specifications of Subpart 15 of FCC Rules, which are
designed to provide reasonable protection against interference in a residential
installation. Operation with non-certified computers is likely to result in
interference with radio and television reception. Note that this equipment may
be compatible and can be used with Class A computers. However, there is no
guarantee that interference will not occur in a particular installation. If this
equipment does cause interference with radio and television reception, which
can be determined by turning the equipment off and on, the user is encouraged
to try to correct the interference as outlined in the User’s Manual for the host
computer, with the following measures: 1) reorient the receiving antenna; 2)
relocate the unit with respect to the receiver; or 3) move the unit away from the
receiver.
If necessary, the user should consult the dealer or an experienced radio/televi-
sion technician for additional suggestions. Changes or modifications not
expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.

Introduction
Thank you for purchasing the DynaPulse. To use this system
correctly and safely, read this manual carefully before operating the
DynaPulse. Retain this manual together with the DynaPulse for
future reference.
NO MEDICATION CHANGES SHOULD BE MADE BASED
ON INFORMATION PROVIDED BY THE DYNAPULSE SYS-
TEM WITHOUT FIRST CONSULTING A PHYSICIAN.
The DynaPulse non-invasive blood pressure system is based on a
unique oscillometric technique, known as Pulse Dynamics. This
technology allows clinically accurate measurements to be obtained
quicklyand easily.

Blood Pressure Defined
Blood pressure is defined as the force generated by the blood as it
flows through the arteries. The heart pumps the blood through the
arteries, which act as "pipes" to carry the blood away from the
heart. This pumping action causes the blood pressure to rise and
fall. When the heart is contracting (pumping), the blood pressure
rises, and when the heart is relaxing (not pumping), the blood
pressure falls. The highest blood pressure achieved in a single cycle
of contraction and relaxation of the heart is systolic pressure. The
lowest pressure during a single cycle is diastolic pressure. Blood
pressure is usually recorded in units of millimeters of mercury
(mmHg), and read with the systolic pressure first. For example,
"120 over 80" indicates a systolic blood pressure of 120 mmHg and
a diastolic pressure of 80 mmHg. Since blood pressure is so
strongly related to the heart, blood pressure is used as a general
index of cardiovascular performance.
How Is Blood Pressure Measured?
There are many methods for measuring blood pressure. The most
accurate method requires the surgical insertion of a catheter into
the patient's artery. The catheter is equipped with a pressure
sensor, which measures the patient's blood pressure directly. These
measurements are considered the "gold standard" for blood pres-
sure measurements. However, most patients do not want blood
pressure measurement to be a surgical procedure! Therefore,
indirect methods were devised to allow safe, quick blood pressure
measurements. The goal of every indirect method is to achieve
measurements that agree with catheter-based measurements.

The most common method for obtaining blood pressure is the
auscultatory method. In this technique, a cuff is wrapped around
the patient's arm, and the physician (or nurse) inflates the cuff, then
places a stethoscope over the arm as the cuff deflates. The physi-
cian is listening for certain characteristic sounds (known as Korot-
koff sounds) to determine systolic and diastolic pressure. The
sounds are created by blood flow in the artery. This method is very
reliable, but extensive training is required to ensure accuracy. In
addition, differences in hearing ability may cause variability between
measurements taken by different people on the same patient, even if
they were taken at the same time! This method has also encoun-
tered difficulty when patient conditions, such as hypotension (i.e.
low blood pressure), mute or damp the Korotkoff sounds.
These difficulties prompted the development of the oscillometric
technique, which does not rely on a microphone. The technique
requires a cuff and a pressure sensor. Instead of listening for
characteristic sounds, oscillometric devices examine the pressures
generated by the cuff and the arterial pulsation to estimate blood
pressure. The estimations are based on large amounts of data, and
are usually accurate, but they are still estimations.
Pulse Dynamics, the patented DynaPulse technology, also mea-
sures the pressures generated by the cuff and the arterial pulsation.
However, it is the only oscillometric method to measure blood
pressure based on physical phenomena, much like the auscultatory
method. Instead of estimating blood pressure, Pulse Dynamics
uses pattern recognition to determine systolic, diastolic, and mean
arterial pressure from the Pulse Dynamic pressure waveform. This
pattern recognition technique is possible due to the effect that
blood flow has on the measured pressures. Pulse Dynamics agrees
extremely well with catheter-based "goldstandard" measurements.

What Is Mean Arterial Blood Pressure?
Mean arterial pressure is the average pressure in the artery over
time. High pressures cause the artery to bulge, like a balloon when
it is inflated. At very low pressures, the artery actually bends
inward slightly. The forces generated by the velocity (speed) of the
blood flow pull the arterial walls inward at these low pressures.
Mean arterial pressure corresponds to the state when the arterial
wall is not distended inwardly or outwardly. The forces due to
blood pressure are in balance with the forces caused by the arterial
wall and the blood flow. By determining mean arterial pressure, we
actually determine the pressure required to balance the arterial wall
forces. Mean arterial pressure is often used in clinical studies, but
no standards have been published regarding its role in the diagnosis
of hypertension.
