Introduction to the Oscar Express ABP Monitor: Oscar 2
The Oscar 2 is a non-invasive oscillometric blood pressure monitor capable of measuring an adult
patient’s systolic and diastolic blood pressures. It is intended for use as an aid or adjunct to
diagnosis and treatment.
AccuWin-Express is used to enable the Oscar 2 for Oscar Express modem communication. Once
enabled, AccuWin-Express is the only software package that can communicate with the Oscar 2
monitor. This includes communication over analog telephone lines via modem and direct
communication to the PC COM port. If Oscar 2-to-PC communication with AccuWin-Pro is
required, the Oscar Express option must be disabled on the Oscar 2 monitor. The Oscar Express
option can only be disabled at the central terminal by AccuWin-Express with the monitor
connected directly to the PC.
Operation
The Oscar 2 unit is worn by the patient either in a waist belt or shoulder strap and is connected to
a cuff placed around the non-dominant upper arm. The cuff is inflated automatically at intervals
that can be programmed during setup. Blood pressure is measured by the oscillometric method
that senses pressure waves in the artery when occluded by pressure in the cuff. Measurement of
the frequency of the pressure waves also allows heart rate to be measured. The Oscar 2 monitor
can record up to 250 measurements.
Blood pressure measurements determined with this device are equivalent to those obtained by a
trained observer using the cuff/stethoscope auscultation method, within the limits prescribed by the
American National Standard, Electronic or Automated Sphygmomanometers .

The Korotkoff
sounds heard over the artery below the compression cuff vary in character as the pressure in the
cuff is reduced from above systolic toward zero or atmospheric pressure. They are divided into
phases. Phase 1 (K1) or systolic begins with the sudden appearance of a faint, clear tapping or
thumping sound that gradually increases in intensity. Phase 5 (K5) or diastolic begins when silence
develops, and is used to determine overall efficacy of the Oscar 2. To obtain results of the study,
