Using the Avant™ 4000 Digital Pulse Oximetry System
General Information about Bluetooth Technology
Bluetooth
is a technology that enables automatic wireless connections between a
variety of electronic communications and computing devices, making it possible to
connect any compatible devices without cables or wires. The technology is based on
a radio link that offers fast and reliable transmissions of voice, video, and data.
Bluetooth uses a license-free, globally available frequency range in the ISM band—
intended to ensure communication compatibility worldwide.
Nonin’s use of Bluetooth Wireless Technology allows SpO
2
, pulse rate, and
plethysmographic data to be transmitted through a Bluetooth radio to a compatible
Bluetooth-enabled device. Nonin’s system removes the connection from the sensor
cable to the display unit, giving patients increased ability to move freely—without
being hindered by cables. Nonin’s patient module uses a class II Bluetooth radio
with a battery life of about 120 hours and a range of about 30 feet (spherical radius).
The display unit has a minimum operating battery life of 18 hours.
Point-to-Point Communications
The Avant 4000 System features point-to-point communications, allowing one
master device (the display unit) to be paired to one slave device (the patient module).
Once connected, neither device is detectable by any other Bluetooth-enabled device,
which reduces the risk of interference and preserves data integrity.
