3.13.6.2 SMMV
Synchronised Mandatory Minute Ventilation
SMMV provdes a set level of mnute volume ventlaton SMMV
allows spontaneous breaths, combned wth a synchronsed
mandatory breath, to acheve the set mnute volume
Select SMMV on the man dsplay
SMMV wll be dsplayed on the man screen
NOTE
1 The trgger wndow s pre-set to 60% of the BPM cycle
tme
2 The trgger s flow actvated
3 SMMV s not avalable f Sprometry s dsabled
4 If the pressure lmt and alarm are actvated the nspratory
phase s termnated

SMMV - Spontaneously Breathng Patent
A = ycle tme (set from BPM)
B = Trgger wndow
= Spontaneous breath
D = Trgger pont
E = Mandatory breath tdal volume
Ths s equal to VM/BPM, mnus the volume
spontaneously breathed durng the cycle (ths
mantans the set VM)
Inspratory flow n the trgger wndow (generated
by the patent’s spontaneous breath) results n a
synchronsed mandatory breath, ensurng that the
set mnute volume s acheved
SMMV - No breathng effort by Patent
A = ycle tme (set from BPM)
B = Trgger wndow
= Flat pressure trace (no breathng effort)
D = Mandatory breath at the end of the trgger
wndow (at the set VM)
If the patent makes no effort to breathe durng a
cycle, a mandatory breath, at the end of the trgger
wndow, wll stll be delvered at the preset volume
and rate
