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.
SpO2
The 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).
