Accurate Measurement
What makes the Tycos QuietTrak Ambulatory Blood Pressure Monitor accurate? Developed and tested by a leader in the blood pressure industry, the Tycos QuietTrak ABPM sets unbeatable standards.
•Auscultatory method — the gold standard in the physician’s office.
•Tested scientifically by Tycos and validated by leading institutions, to meet accuracy standards set by The Association for the Advancement of Medical Instrumentation (AAMI) and The British Hypertension Society.
•Blood pressure measurements determined by this device are equivalent to those obtained by a trained observer using the auscultation method. Measurements are within the limits prescribed by ANSI for electronic sphygmomanometers.
•Verifiable accuracy. With the Calibration Check feature, you can compare the ABP monitor’s measurement with your office manometer and be assured that the results are reliable.
•Linear deflation is adjustable at 2, 3, 4, 5, or 6 mmHg per heartbeat.

Patient-Friendly Design
Tycos developed a small, quiet ABP monitor with the patient’s comfort in mind, and there are no electrodes to wear.
•Lightweight — only 12.5 ounces (355 gms) with batteries.
•Small package — 4.5 x 3.4 x 1.6 inches (11.43 x 8.6 x 4.1 cm).
•Quiet cuff inflation and silent deflation make the Tycos QuietTrak ABPM ideal in the ambulatory environment because it is hardly noticed. That’s so the ABP monitor can do its job while the patient does his.
•Patient Activation Button is easily accessible by the patient; an opening on the pouch guides the patient’s finger to the button by touch, without having to look.
•Real time clock on the ABP monitor’s display assists the patient with diary notations.
Programmability
•Programming is quick and uncomplicated, with simple threebutton control and the LCD.
•Programmable periods — The automatic measurement intervals are selectable from 5 to 120 minutes, with up to four different time periods.
•The Start Button allows patient activation of readings, but can be disabled.
•Measurement Parameters can be modified from one ABP monitoring procedure to the next, and customized to the patient’s needs or the type of study being done.
•The parameters you select are stored in memory so that you won’t have to reselect ABP monitoring parameters from one procedure to the next.
Data Retrieval
•All measurement data can be quickly reviewed on the QuietTrak liquid crystal display
•Direct connection to Epson compatible printer for standard hard copy report.
•Optional PC program allows customized data and report generation via a variety of printers.

The Data Summary
A Summary contains information about the Regular Run readings, including the time and date of the first and last attempted Regular Run readings.
Number of readings expected includes all programmed and manual readings.
Number of readings used is the number of accepted readings.
Minimum, Maximum, Average, Number of Systolic > 140 mmHg, Number of Diastolic Readings > 90: These are calculated from the accepted Regular Run readings.
B Hourly Averages are presented in a table that includes data from the Regular Run readings for each of the 24 one-hour intervals in a day. If ABP monitoring was conducted for more than a one-day period, then the hourly averages include the values obtained during that hour for all days of use.
The table contains these values:
Hour always begins on the hour (i.e., 07 AM) and ends after the last minute of the hour.
Num is the number of Regular Runs taken during each onehour period.
Sys is the average Systolic value for each hour.
Dia is the average Diastolic value for each hour.
HR is the average heart rate value for each hour.
The data is also represented graphically to the right of the data table. The average Systolic and Diastolic values are shown as “*”, and the average heart rate values are indicated with an “0”.

Battery Requirements
!
!
Replace Batteries for Every Patient Study.
Install four new AAA alkaline batteries prior to each patient hookup. Fresh batteries provide the power to inflate the arm cuff 100-300 times during a oneor multi-day period. For maximum ABP monitoring periods, fresh batteries are required.
If the ABP monitor reaches a low battery state, it automatically discontinues the measurement cycle to reserve the power it will later need to transfer the data. Partially-used batteries shorten the ABP monitoring session. Therefore, attempting an ABP monitoring session with used batteries is not recommended.
Data Storage Protection: An internal battery of the Tycos QuietTrak ABPM powers the data’s memory storage and protects the data even if the AAA batteries wear down. Data is preserved even during battery replacement.
Concerning the Use of Rechargeable Batteries:
Rechargeable NiCad batteries can be used in place of alkaline batteries. With fully-charged NiCad batteries, 100 measurement cycles are achievable with average case usage (Medium size cuff and 180 mmHg average inflation level). The length of the ABP monitoring session could vary with different cuff sizes or with batteries which are not fully charged.
Remove the Batteries to Store the ABP monitor.
At the conclusion of an ABPM procedure, we recommend that you print the report and remove the used batteries from the unit. This will eliminate the risk of attempting a new patient study with used batteries. If you want to wait to print the report at a later time, go ahead and remove the batteries; the internal lithium battery will retain all patient data until you retrieve it or intentionally erase the data.
Internal Battery
An internal lithium battery powers the time, date, parameters, and data retention for at least five years. The internal battery ensures that the ABP monitor won’t lose data when you remove or replace the AAA batteries.
When the internal battery needs replacement, return the ABP monitor to the nearest Welch Allyn/Tycos Service Center.
