GLOSSARY
Gl-4
Minute alveolar ventila-
tion See MValv
Minute volume See MV
MS Mainstream CO

sensor (service menu message).
MV
Minute volume (the sum of tidal volumes per minute).
MValv Minute alveolar ventilation.
MVe_sp / MVe Factor of spontaneous breathing.
MVexp Expiratory minute volume (volume eliminated from the patient)
MVspont
Minute volume of spontaneous breaths.
NIV Non-invasive ventilation of lungs. The mode of spontaneous breathing with a
set positive pressure in the airways and set support of spontaneous breathing
through the face mask. The mode is very similar to CPAP+PS, the differences
are due to the inevitability of leakage in non-invasive ventilation.
Occlusion Blocking of patient’s expiration or inspiration. Can be caused by the action of
the ventilator or occlusion of the respiratory circuit.
Open Valve “Open valve” function. Reflects the current trend of maintaining and supporting
spontaneous breathing at all stages of ventilation. See it.4.21 “Open valve func-
tion”
Oxygen consumption See VO

P0.1 Respiratory effort index. Index characterizes the strength of the patient's
breathing attempts. It is measured in cmH

concentration obtained using one of the laboratory techniques
Paux Auxiliary external pressure.
Paw Airway pressure waveform (graph).
PCV-VG
Mandatory ventilation with guaranteed delivery of target respiratory volume at
minimum possible pressure. Functionally mode repeats the CMV / PCV mode
with one exception: instead of the target pressure, the user sets the target in-
spiratory volume. The inspiratory pressure is corrected by the device with each
new inspiration according to the target volume.

Capnogram (graph).
Peak inspiratory flow See FlowPeak
Peak inspiratory pres-
sure See PIP
PEEP Positive end-expiratory pressure
PEEPtot True pressure level in lungs at the end of expiration. Pressure in the lungs at
the end of expiration, taking into account the incomplete expiration
PEEPtot= PEEP + AutoPEEP. Displayed if both parameters are measured cor-
rectly.
Phigh
Pressure value in the high pressure phase (in the BiSTEP, APRV modes).
Photoplethysmogram
(PPG) Graph showing the change in tissue transparency in the section of the optical
sensor. Transparency of tissues changes due to narrowing and widening of
blood vessels because of pulsating arterial blood.
Pi
Inspiratory pressure.
Piapnea Inspiratory pressure above apnea PEEP level in the apnea mode.
PIP
Peak inspiratory pressure.
Plateau pressure See Pplat.
Plateau time Selection the measuring units (% or sec).
