Remark
The expiratory time constant is a measure of the complete ex -
piration while avoiding an auto-PEEP situation. For this measure-
ment, the expiratory flow is determined at 75% of the expiratory
vital volume and the necessary expiration time is calculated.
The following standard values are applicable for the necessary
expiration time:
1 x RCexp 63%
2 x RCexp 86.5%
3 x RCexp 95%
4 x RCexp 98%
8.5

Measurement values and indexes relevant for the weaning procedure can be
