The microvent®
is a time/volume cycled resuscitator, the type recomended for emergency
resuscitation.*

Resuscitation Guidelines
discuss the breath size and frequency needed for resuscitation. A breathing
cycle consists of Inspiration (breathing in) and Expiration (breathing
out). The number of complete cycles that occurs within one minute is
the frequency in breaths per minute (BPM). As inspiration is driven
(by the resuscitator) and expiration is passive, a longer period is
allowed for expiration. The ratio between Inspiration and Expiration
(known as the I:E ratio) is set on the microvent® at a nominal 1:2 (as
required by the ISO standard). The size of the breath applied is known
as the Tidal Volume. The microvent® volume/time cycled resuscitator
is calibrated to provide volumes and frequency consistently and tirelessly.
Unlike expired air resuscitation or using a bag/mask resuscitator, microvent®
supplies a measured ventilation volume accurately and regularly without
the need for rest. And it enables easy application of 100% oxygen without
wastage. With a spontaneously breathing person, an adult breaths less
frequently and with larger breaths than a child. The microvent® mimics
this physiological difference in its automatic mode and the child settings
are more frequent with smaller breaths than the adult settings.

"ATVs used for prehospital care should be simple and time- or volume-cycled.
Avoid pressure-cycled devices."
