Rise Time: Levels 1–3 (adjustable)

Inspiratory / Expiratory Times: 0.3–3.0 seconds

Expiratory Pressure Relief (EPR): 0–3 cm H₂O

Humidifier: Built-in HumidAir™ heated humidifier, supports heated tubing with ClimateLineAir for better comfort

IntelligentAir Technology:

Vsync: Maintains synchrony even with leak

TiControl: Lets you set min/max inspiratory time to match patient’s breathing pattern

Trigger & Cycle Sensitivity: 5 sensitivity levels for both trigger (start of breath) and cycle (end of breath)

Comfort Features:

QuickNav: Easy navigation between settings and monitoring screens

Ramp & Ramp Down: Gradually increases or decreases pressure at start/end for comfort

Noise Level: < ~35 dBA (very quiet)

Use Case: For patients with respiratory insufficiency who breathe spontaneously but need backup support (ST mode)

Supplemental Oxygen Support: Compatible (e.g., can connect up to 15 L/min in ST mode) per some sources.

⚠️ Things to Consider / Pros & Cons

Pros:

Very versatile modes (S, T, ST, CPAP) — good for different patient needs.

IntelliigentAir tech helps synchronize with patient breathing, even with leaks.

Quiet and compact, making it feasible for home use.

Integrated humidifier + heated tube support increases comfort (reducing dryness).

Remote monitoring (Cloud) is useful for caregivers / clinicians.

Considerations:

ST mode gives backup breaths: not for fully dependent ventilator patients.

Users on Reddit report that in ST mode, pressure “drops abruptly” after inspiratory phase under some settings. > “pressure drops each time before I finish inhaling”

Requires regular maintenance: cleaning humidifier, filters, etc.

Because it’s advanced, may require setup / tuning by a clinician (especially trigger/cycle, backup rate).
