O 2 Cylinder Duration<br />
Use the O2 Cylinder Duration option to calculate the approximate remaining usable time (in hours and<br />
minutes) of an external O2 cylinder.<br />
• To obtain an accurate duration time estimate, the current cylinder pressure must be entered prior<br />
to each calculation.<br />
WARNING<br />
O2 Cylinder Duration Information - The accuracy of the displayed useable amount of oxygen<br />
remaining in an external O2 cylinder (O2 DUR hh:mm) is dependant on the precision of the pressure<br />
gauge used on the O2 cylinder and the accuracy of the information provided by the operator in the O2<br />
CYL DUR menu settings. The calculated/displayed useable amount of oxygen information is to be<br />
used for reference purposes only.<br />
Ventilation Variables and O2 Consumption - Variations in the patient’s minute ventilation, I:E ratio<br />
and/or ventilator setting changes or equipment status (i.e. circuit leaks) affect the consumption rate of<br />
oxygen. When warranted by a patients condition, it is recommended that a back-up cylinder or<br />
alternative source of oxygen be available at all times.<br />
AVERTISSEMENT<br />
Informations sur la durée d'utilisation restante de la bouteille d’oxygène - La précision de<br />
l’affichage de la quantité d’oxygène utilisable restante dans une bouteille d’oxygène externe (O2 DUR<br />
HH:MM) dépend de la précision de la jauge de pression utilisée sur la bouteille et de l'exactitude des<br />
informations fournies par l’opérateur dans les paramètres du menu DUREE CYL O2. Les<br />
informations calculées et affichées sur la quantité d’oxygène utilisable ne doivent être utilisées qu’à<br />
titre indicatif.<br />
Variables de ventilation et consommation d’oxygène — Les variations dans la ventilation par<br />
minute du patient et dans le rapport inspiration/expiration, la modification des paramètres ou l’état du<br />
matériel (fuite dans le circuit, par exemple) modifient le taux de consommation de l’oxygène. Lorsque<br />
la situation du patient le permet, il est recommandé qu'une bouteille d’oxygène de secours ou toute<br />
autre source alternative d’oxygène soit disponible en permanence.<br />
To modify the O2 Cylinder Duration settings:<br />
1) Push the Select button while O2 CYL DUR is displayed and CYL TYPE is displayed.<br />
2) Push the Select button while CYL TYPE is displayed and SIZE xxx l is displayed.<br />
3) Turn the Set Value knob until the applicable O2 cylinder size is displayed (volume in compressed<br />
Liters), push the Select button and the cylinder size is set.<br />
• Range: 75 - 9,900 compressed Liters, in increments of 1.<br />
• This setting is retained by the ventilator (through shut downs and power ups) until re-set by<br />
an operator, and used to calculate the remaining oxygen.<br />
• After changing this, or any ventilation setting, wait approximately 20 seconds before selecting<br />
CALCULATE, to allow the ventilator to monitor the oxygen flow that will be used in the<br />
calculation and display of the remaining usable time of the external O2 cylinder.<br />
