Leak

Leak measurement (L/min)

MV

Minute Ventilation measurement, averaged over 5 breaths (L/min)

RR

Respiratory Rate measurement, averaged over 5 breaths (BPM)

Vt

Tidal Volume measurement, averaged over 5 breaths (mL)

TGMV

Target Minute Ventilation, 90% of the patient’s minute ventilation for the last 3 minutes. (L/min)

Ti range

Minimum and Maximum Inspiratory Time setting (sec)

I:E

Ratio of inspiratory period to the expiratory period, averaged over 5 breaths

TI

Inspiratory duration measurement, averaged over 5 breaths (sec)

Spont Trig

Percentage of breaths that are spontaneously triggered over the last 20 breaths since therapy has started

Spont Cyc

Percentage of breaths that are spontaneously cycled over the last 20 breaths since therapy has started

Machine Cycled Breath Indicator

SL UI screenshot Machine Cycled Breath Indicator

SL UI screenshot Arrow right-hand side right

Arrow on the right hand side pointing right.

This indicator identifies there has been a spontaneous effort from the patient to cycle to EPAP before the set TiMin has been reached. The machine cycles when TiMin has been reached.

SL UI screenshot Arrow right-hand side left

Arrow on the right hand side pointing left.

This indicator identifies that there has been no spontaneous effort from the patient to cycle to EPAP. The machine cycles when TiMax has been reached.

Machine Triggered Breath Indicator

SL UI screenshot Arrow left-hand side right

Arrow on the left hand side pointing right.

This indicator identifies that set respiratory rate or backup rate has been reached to trigger to IPAP. The machine triggers when backup rate has been reached.

[a] EPAP for ASVAuto mode is displayed as a range.

[b] PS for S, ST and T mode is derived from the EPAP and IPAP settings. PS for ASV and ASVAuto mode is displayed as a range.
