Key Features & Specifications Model: [ResMedโฏLumisโฏ150โฏVPAPโฏST]() Type: Non-invasive ventilator / BiPAP Modes: CPAP, S, T, ST, PAC, iVAPS Intelligent Volume-Assured Pressure Support (iVAPS) to maintain target alveolar ventilation. Intelligent Backup Rate (iBR) โ supports spontaneous breathing and adds mandatory breaths if needed. Optional AutoEPAP (adjusts expiratory pressure to maintain airway openness) in iVAPS mode. Vsync: helps synchronize patient and ventilator, even with leaks. TiControl: you can set minimum and maximum inspiratory times. Trigger & Cycle Sensitivity: 5 levels for fine-tuning. QuickNav: double-click the home button to switch between settings and monitoring screens quickly. Ramp & Ramp Down: adjustable 0-45 min to smoothly increase/decrease pressure. Humidification: Comes with HumidAirโข heated humidifier + ClimateLineAirโข heated tube (for automatic humidification). Alarms (in ST-A version): power failure, system fault, high leak, low minute ventilation, apnea, low SpOโ (if oximeter connected) Connectivity: 4G (for remote monitoring), SD card support, compatible with ResMedโs ResScan / AirView. Dimensions: ~ 116 ร 255 ร 150 mm (device + humidifier) Weight: ~ 1.34 kg (with humidifier ~1.33 kg) Pressure Range: S, ST, T, iVAPS, PAC modes: ~2โ30 cm HโO CPAP mode: ~4โ20 cm HโO Noise Level: ~ โค 25 dB (very quiet) Water Chamber Capacity: 380 mL Electrical Specs: 100-240 V AC, 50/60 Hz; typical consumption ~53 W, peak ~104 W (with humidifier) Certification / Safety: FAA-approved for air travel. Pros & Use Cases Good for patients with respiratory insufficiency (obstructive or restrictive) who need ventilation support but are not fully dependent. iVAPS + iBR makes it adaptive: the machine can adjust to changing breathing needs. Automatic humidification makes therapy more comfortable. Remote monitoring (4G) is helpful for clinicians to follow up on therapy. Quiet operation โ less disturbance during sleep.
