  • Page 8: Blood Pressure Defined

    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 Introduct fall.
  • Page 9 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.

  • Page 10: What Is Mean Arterial Blood Pressure

    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.

  • Page 11: Facts About Hypertension

    Facts About Hypertension Hypertension is described as a persistently elevated blood pressure that exceeds predetermined thresholds. The Sixth Report of the Joint National Committee on Detection, Evaluation, and Treatment of Hypertension estimates that 50 million Americans have blood pressures that consistently equal or exceed 140/90 mmHg, and are therefore at increased risk for developing cardiovascular diseases such as coronary heart disease and peripheral vascular disease.
  • Page 12 Hypertension as a risk factor for cardiovascular disease Hypertension increases the risk for developing many cardiovascular diseases, including atherosclerosis and left ventricular hypertrophy. Other risk factors for cardiovascular disease include: smoking, Introduc diabetes mellitus, lack of exercise, and excessive alcohol intake. Hypertension management Mild cases of hypertension can be treated effectively by non-drug therapies.

    The DynaPulse is linked to the computer and its software by the communications cable. All of the data is stored, displayed, and analyzed on your computer.
  • Page 14 • Repeated deep breaths, coughing, sneezing, and talking may affect the reading. The patient should relax and remain motionless during each blood pressure measurement. • A rolled-up sleeve may constrict blood flow through the arm. Putting all or part of the cuff on top of a sleeve may affect the reading’s accuracy as well.

  • Page 27: Putting On And Using The Cuff

    Putting On And Using The Cuff Loop the cuff with the Velcro interlock on the inside. If the cuff does not fit, switch to a different cuff size. See Selecting the Correct Cuff. Locate the brachial artery on the left arm. It is located on the inner side of the upper part of the arm.
  • Page 28 Fold the end of the cuff so that it fastens onto the Velcro panel. Don't put the cuff on too tightly. Plug the tube connector into the DynaPulse unit. Close the release valve on the pressure bulb. (Turn the knob clockwise completely.)
  • Page 29 The arm should rest on a table surface. Do not let the cuff rest on any other surface. When the program asks you to start pumping, squeeze the pressure bulb to pump up the cuff. When the program has completed its measure- ment, release the remaining air pressure in the cuff by slowly turning the valve counterclock- wise.

  • Page 33 At these points the cuff pressure was equal to (from left to right) systolic, mean arterial, and diastolic blood pressures. The Pulse Dynamic algorithm used by the DynaPulse products uses pattern recognition to determine blood pressures.
  • Page 34 For convenience, the blood pressures are displayed on the top right hand corner of the screen, along with heart rate. When first looking at the waveform, one may immediately notice two striking features: the pressure oscillations (the peaks and valleys) , and the increasing then decreasing height of the oscilla- tions with time.
  • Page 35 Estimated Measurements The DynaPulse has the capability to estimate one measurement parameter (such as systolic), provided that it has measured the other two. An estimated measurement can be distinguished from other measurements by the presence of a highlighted background. Estimated measurements occur when either the High or Low Range is not set correctly.

  • Page 36: Adjusting The Measurement Settings

    Adjusting Measurement Settings When taking the first set of measurements for a new user, you should adjust the cuff size and Air Release index for the user. This may require a few test measurements. Once these parameters have been set, however, they will be saved along with the user's data and will not need to be adjusted.
  • Page 37 Adjusting the Air Release The total measurement time should be 25-35 seconds. Measure- ment time is displayed above the arterial waveform (in seconds). If the total measurement time is outside this range, the Air Re- lease index needs to be adjusted. Adjust the Air Release index by choosing AIR RELEASE from the MEASURE menu.
  • Page 38 Adjusting the High and Low Range Settings The HIGH and LOW RANGE features enable the user to set HIGH and LOW blood pressure limits. The default settings are 160 (systolic) and 50 (diastolic) mmHg. The HIGH RANGE varies from 100 to 280 mmHg in 20 mmHg increments.

    Windows 95/98 is capable of detecting most standard COM ports, therefore we recommend that you use the standard serial ports (COM 1 or COM 2) for your DynaPulse. If the use of COM ports 3 or 4 is necessary, the configuration procedure is provided below.

  • Page 53: Selecting The Correct Cuff

    Selecting the Correct Cuff The American Heart Association makes the following recommenda- tions with regard to determining the correct cuff size: ♦For adults, the bladder inside the cuff should encircle 80% of the arm. ♦For children less than 13 years of age, the bladder should encircle 100% of the arm.

  • Page 54: Error Messages

    If you are using the DynaPulse for the first time, verify that the I/O PORT option is set to the port that the DynaPulse is connected to.
  • Page 55 Air Release Too Fast If you receive this message, check for cuff leaks or hose and connector leaks. If no leaks are found, check the mea- surement time (the time scale is located Messages Messages above the arterial waveform). The total measurement time should be 25-35 seconds.
  • Page 56 ♦The DynaPulse program requires that you pump over the selected "HIGH" range so the DynaPulse system can obtain useful data at the start of the selected High range. For instance, if the High range is set at 160 mmHg., the program will require the user to pump over 160 before told to stop pumping.
  • Page 57 High Pressure Range is Set Too Low. The DynaPulse did not pump to a sufficiently high pressure to measure the systolic pressure. Messages If the you are asked to increase the HIGH RANGE, choose HIGH RANGE from the MEASURE menu and increase the range by one step (for example 160 to 180).
  • Page 58 Low Pressure Range is Set Too High. The DynaPulse did not measure to a sufficiently low pressure to measure the diastolic pressure. If the you are asked to decrease the LOW RANGE, choose LOW RANGE from the MEASURE menu and decrease the range by one step (for example 50 to 40).

  • Page 59: Dynapulse Accuracy And Tips For Use

    DynaPulse Accuracy All DynaPulse systems are clinical-grade. The DynaPulse is FDA- registered, and meets or exceeds Association for the Advancement of Medical Instrumentation (AAMI) standards for non-invasive blood pressure monitors. However, like any other device, proper use of the DynaPulse is essential for accurate measurements.
  • Page 60 General Tips The following suggestions will increase the accuracy of blood pressure measurements in general. They do not apply exclusively to the DynaPulse. •Allow 1-3 minute intervals between measurements • The user should relax and remain motionless during each blood pressure measurement.
