Arrangement for dosing breathing gas closes interrupter on reaching defined breathing volume and, releases closed position when second minus first measurement pressure difference less than null

摘要

The arrangement has a breathing volume measurement device (6) for a breathing volume between a breathing bag (8) and a patient adapter (2), a first pressure measurement device (4) and a breathing gas interrupter (5) in series between the adapter and the breathing volume measurement device, a second pressure measurement device (7) between the breathing volume measurement device and the bag, a control unit (6) that closes the interrupter on reading a defined breathing volume and releases the closed position when the second minus first measurement pressure difference is less than null. An independent claim is also included for the following: (a) a method of dosing a defined breathing volume.
