LTV 1100 Operator Manual - CareFusion

Pressure Support
This control establishes the target pressure above the PEEP setting for Pressure Support patient
breaths. If Pressure Support is set to dashes “- -“, all patient breaths will be given as Spontaneous
breaths. Inspiratory flow for Pressure Support and Spontaneous breaths is controlled to meet the
patient demand.
NOTE
Pressure Support breaths on the LTV ® 1100 are compensated for PEEP. Delivered pressure is
controlled by the Pressure Support setting and is affected by the PEEP setting. For example, a
Pressure Support setting of 20cmH 2 O and a PEEP setting of 10cmH 2 O results in a Peak Inspiratory
Pressure (PIP) of 30cmH 2 O.
REMARQUE
La pression de support des respirations sur le LTV ® 1100 sont compensés pour la pression
expiratoire positive (PEP). La pression administrée est contrôlée par le réglage de la pression de
support et elle dépend du réglage PEP. Par exemple, un réglage de la pression de support de
20 cmH2O et un réglage PEP de 10 cmH2O donnent une pression inspiratoire maximale (PImax) de
30 cmH2O.
To set Pressure Support:
1) Push the Pres. Support button.
2) Change the setting using the Set Value knob.
Range: “- -”, 1 - 60 cmH 2 O
Pressure Support breaths may be terminated by flow or by time.
Flow Termination: Pressure Support breaths are flow terminated when the flow decreases to a set
percentage of the peak flow 12 delivered for that breath.
Time Termination: Pressure Support breaths are time terminated 13 when the inspiratory time exceeds
two breath periods, or when the inspiratory time exceeds the set Time Termination Limit 14 before the
flow termination criteria is reached. The Pres. Support display will flash briefly after each time
terminated breath.
The Rise Time profile for Pressure Support breaths may be selected under Extended Features 14 .
12 See Chapter 10 - Extended Features to set the Variable Flow Termination for Pressure Support breaths.
13 Only Pressure Support breaths are flow and/or time terminated (Time Termination must be enabled).
14 See Chapter 10 - Extended Features to set the Variable Time Termination or Flow Rise Time profile.
