Usage	Total hours used, Daily usage, Used Days ≥ X:YY hours, Used Days < X:YY hours, Total days and % Used Days. Calculated for the selected sessions in the Data Browser.	Each period is shown as a solid bar. A hollow bar indicates a period of usage where the end-time is unknown. There is a limit on the maximum number of separate bars that are shown for a single session.
% Spontaneous (Triggered) Breaths	Shows percentage of breaths that are spontaneously triggered.	Shows percentage of breaths that are spontaneously triggered for single sessions.
% Spontaneous (Cycled) Breaths	Shows percentage of breaths that are spontaneously cycled.	Shows percentage of breaths that are spontaneously cycled for single sessions.

Alarms include: mask/leak alarm, non-vented mask, low minute ventilation, low pressure and high pressure.

Glossary of Terms

AHI (Apnea-Hypopnea Index)
The Apnea-Hypopnea Index (AHI) is calculated by adding together the total number of apnea and hypopnea events over a period of time.

For statistics, it is the total number of events divided by total daily usage. For graphs, the AHI count is incremented at the occurrence of every event and reset every hour.

Apnea
An apnea is the temporary absence or cessation of breathing. An apnea is scored when there is reduction in breathing by 75% of the baseline breathing for at least 10 seconds.

Daily Usage
Daily usage is total usage in a single session (a session starts at midday and finishes 24 hours later).

EPAP (Expiratory Positive Airway Pressure)
EPAP is the pressure delivered to the patient during the patient’s expiratory phase.

Events
An event is the occurrence of a residual apnea or hypopnea.

Events are recorded as they occur. The maximum number of events stored per session is 500 (including alarm events).

Up to 2000 events may be stored if a ResLink is used.

Flow
Flow is an estimate of the airflow entering the lungs.

It is derived by taking the total flow and then removing the leak and mask vent flow components.

Hypopnea
A hypopnea is an episode of shallow breathing during treatment. A hypopnea is scored when there is a reduction in breathing by 50% of baseline breathing for 10 seconds or more. The event is scored after 10 seconds of the hypopnea.

I:E Ratio
The ratio of inspiratory time to expiratory time.

Inspiration Time
Inspiration time is the duration of inspiration (ie, the respiratory flow into the lungs).

It is calculated by averaging the inspiration time for the last five breaths.

IPAP (Inspiratory Positive Airway Pressure)
IPAP is the pressure delivered to the patient during the patient’s inspiratory phase.

Leak
Leak is an estimate of the total rate of air escaping due to mouth and mask leaks.

It is derived by analyzing the inspiratory and expiratory airflows, together with the expected mask vent flows.

High or changing leak rates may affect the accuracy of other measurements.

Minute Ventilation
Minute ventilation is the volume of air breathed in (or out) within any 60-second period.

Pressure (ResControl II)
Pressure is an estimate of the pressure delivered at the mask.

Pressure (Results Screen)
The pressure is an average that includes the IPAP and EPAP excursions. As such, the measured value for pressure lies between these levels.

Pressure (Treatment Screen)
Instantaneous mask pressure (estimated).

Pulse Rate
The number of heart beats in a 60-second time frame. The pulse rate is calculated by an attached oximeter.

Respiratory Rate
Respiratory rate is the frequency of breathing, expressed as the number of breaths per minute.

SpO₂The saturation of blood hemoglobin with oxygen, expressed as a percentage. The oxygen saturation is calculated by an attached oximeter.

Tidal Volume
Tidal volume is the volume of air inspired or expired in one respiratory cycle (breath).

Total Hours Used
Total hours used is the total patient usage since the hourmeter was last reset.

Usage
Usage is the length of time that a patient receives therapy from the device.

The start and end times of the first ten individual periods of usage are available for each session when using ResScan.

% Spontaneous Cycled Breaths
% spontaneous cycled breaths is the percentage of patient breaths that were spontaneously cycled (termination of IPAP and changing to EPAP).

% Spontaneous Triggered Breaths
% spontaneous triggered breaths is the percentage of patient breaths that were spontaneously triggered (initiation of IPAP).
