Battery
InformationA sealed lead acid battery supplies battery backup for the Aestiva. The Aestiva is not a 
portable unit. Batteries are used as back up power in case of a power failure. Thus the 
battery is in a float charge state most of the time. Batteries meet the following:
1. Capacity to operate for 30 minutes.
2. Unit functions to specifications through the transition to battery power.
3. Long float charge life.
4. Battery pack...

Aestiva ventilator accuracy data
The following accuracy data are based on patient conditions and settings described in 
ASTM F1101. The ventilator is assumed to be operating in volume mode (Heliox Off). For 
the following to be true, the ventilator is operating with 100 percent oxygen in the 
breathing system; or, it is connected to an anesthesia gas analyzer. If the ventilator is 
operating without being connected to an anesthesia gas...

Heliox modeThe effect on volume delivery and monitoring accuracies of Heliox mixtures is within +8% 
to -15% when operating the Aestiva Ventilator in the Heliox mode.
Open loop mode volume delivery accuracy: ±10% of the set value under the following 
conditions:
1. Accuracy evaluated at the ventilator outlet.
2. This is not a normal operating mode. The ventilator is operating in an irregular 
condition.
