7.1.3. Airow
Anormal respiratory rates and changes in respiratory rate are a broad indicator of major physiological instability,
and in many cases, respiratory rate is one of the earliest indicators of this instability. Therefore, it is critical
to monitor respiratory rate as an indicator of patient status. AirFlow sensor can provide an early warning of
hypoxemia and apnea.
7.1.3.1. Sensor features
Description: The nasal / mouth airow sensor is a device used to measure the breathing rate in a patient in need
of respiratory help or person. This device consists of a exible thread which ts behind the ears, and a set of two
prongs which are placed in the nostrils. Breathing is measured by these prongs.
The specically designed cannula/holder allows the thermocouple sensor to be placed in the optimal position
to accurately sense the oral/nasal thermal airow changes as well as the nasal temperature air. Comfortable
adjustable and easy to install.

The sensor needs to be connected to the specic Airow jack connector in MySignals board and it works with
direct connector power supply.
