The values displayed in the patient data screen are described below. Measurements
that are not available are shown as “--”. Measurements may not be available when the
Airvo 3 is in standby mode or the device has not collected enough data for a reliable
measurement.
Label Unit Description
Flow L/min The current flow rate of breathing gases supplied to the patient
RR BPM The patient’s respiratory rate (breaths per minute), averaged over the last 90 seconds
Humidity °C The current humidity of breathing gases supplied to the patient
FiO

% Peripheral blood oxygen saturation measured by pulse oximeter
PR BPM Pulse rate measured by pulse oximeter (beats per minute)
6.2 Live value graphs
Airvo 3 live value trends graphs show the last 30 seconds of data.
Label Unit Description
Flow L/min The current flow rate of breathing gases supplied to the patient
6.3 Long term graphs
Airvo 3 Data and Graphs show measurements plotted against time for up to 24 hours. New measurements are added to the right side of
the graph. Prior data will scroll to the left as new measurements are added. Gaps will appear in the plotted data if therapy is stopped or
measurements are missing due to poor signal quality.
The graphs available are described in the table below.
