Introduction
The Apneas per Hour (A/hr) and Oxygen Desaturation Index (ODI) algorithm is part of the Smart Capnography
family of innovative algorithms developed by Oridion. Smart Capnography simplifies the use of CO

enabled products, to improve patient safety and clinical workflow.
A/hr and ODI are not available in all locations. In order to equip your device with these algorithms, contact
Capnographyinfo@covidien.com .
A/hr and ODI provide an easy way to help with the identification and quantification of apnea and oxygen
desaturation events during a patient’s hospital stay.
A/hr and ODI report apnea and oxygen desaturation events and calculates the associated Apnea per Hour (A/hr)
and Oxygen Desaturation Index (ODI). By using A/hr and ODI, clinicians are able to recognize ventilation and
oxygenation abnormalities while patients are being monitored during their hospital stay with Capnostream. A/hr
and ODI are for adult patients only (age 22 and older).
A/hr and ODI are displayed in real time on the home screen and on an easy-to-read Apnea and O

Desat Report
screen, which is available for printed reports and in file format exported to a USB flash drive.
Apneas per Hour
An apnea is a period of time during which breathing stops or is greatly reduced. The Apnea per Hour (A/hr)
calculated by the Capnostream monitor as seen on the Home screen provides a count of the number of pauses of
at least 10 seconds in breathing the patient experienced over the past hour.
On the Apnea and O2 Desat Report screen, A/hr is the average Apneas per Hour over the selected time period
of 2, 4, 8 and 12 hours. On that screen, the number of apnea events of
≥10 seconds; 10-19 seconds;
20-30 seconds; and >30 seconds over the selected time period are also shown.
This A/hr value is used to help indicate to the caregiver the regularity of the patient’s breathing.
The Capnostream Apneas per Hour
In the Capnostream device, apnea per hour is a count of the number of times in an hour that breathing ceased for
ten seconds or more. Since this is a per-hour count, dashed lines will appear on the screen until one hour has
commenced since the beginning of monitoring.
A/hr is currently available for adult patients only and is intended for patients age 22 and older. It is not available
for infants (age 0-1) or for patients under age 22.
