Principles of operation
16.7 Influence of patient category, weight, and age on
device behavior
16.7.1 Influence of patient category
– Alarm limits and start settings for therapy
– Volumeter scale
– Flow measurement and software algorithms to suppress artifacts
– Maximum duration of a pressure-supported breath
16.7.2 Influence of ideal body weight and body height
Ideal body weight describes the portion of the body that is relevant to setting the
ventilation parameters (body weight of the patient minus assumed excess fat).
In the Adult and Ped patient categories, the ideal body weight is calculated from the
entered body height.
In the Neo patient category, the ideal body weight is equal to the entered body
weight.
The calculated ideal body weight affects the following:
– Start settings for tidal volume VT
– Start settings for respiratory rate RR
– Start settings for alarm limits for VT and MV
– Ventilation algorithms
– Trigger threshold (insp. synchronization of the mandatory breaths)
– Sensitivity and resolution of the volume monitoring
– Rate of concentration changes affecting the patient
For neonates, the patient category and the ideal body weight must be set with
particular care.
VT and RR are only dependent on the ideal body weight when the Ideal body
weight function has been selected in System setup > Therapy, see page 210.
