Here are the basic details for the ResMed Lumisโฏ100โฏVPAPโฏST (also called BiPAP ST): โ Key Features & Specifications Therapy Modes: Biโlevel Positive Airway Pressure (BiPAP) S (spontaneous), T (timed), ST (spontaneous/timed) modes CPAP mode also supported Pressure Range: IPAP (inspiratory): 4โ25 cmHโO EPAP (expiratory): 4โ20 cmHโO Backup Rate (iBR): Adjustable 4โ40 breaths per minute in ST mode Rise Time: Levels 1โ3 (adjustable) Inspiratory / Expiratory Times: 0.3โ3.0 seconds Expiratory Pressure Relief (EPR): 0โ3 cm HโO Humidifier: Built-in HumidAirโข 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 patientโs 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 Connectivity / Data: SD card for data storage. Built-in wireless connectivity for remote monitoring via ResMedโs cloud platform (AirView). Power & Physical Specs: Input: 100โ240โฏV AC, 50/60 Hz Typical power use: ~53 W; peak: ~104 W Operating temperature: 5โ35 ยฐC; humidity: 10โ95% RH Dimensions: 116 ร 255 ร 150 mm Weight: ~1.268โฏkg 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. โ ๏ธ Things to Consider / Pros & Cons Pros: Very versatile modes (S, T, ST, CPAP) โ 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 โdrops abruptlyโ after inspiratory phase under some settings. > โpressure drops each time before I finish inhalingโ Requires regular maintenance: cleaning humidifier, filters, etc. Because itโs advanced, may require setup / tuning by a clinician (especially trigger/cycle, backup rate).
