The Lifestyle Ventilator Luisa by Löwenstein Medical redefines home ventilation by combining high-performance technology with an award-winning “lifestyle” design. Unlike traditional medical devices, Luisa is aesthetically pleasing and intuitive, helping it blend seamlessly into your daily life. It is versatile enough to be operated vertically or horizontally, allowing it to fit easily on a bedside table, wheelchair, or in a travel bag.
Unmatched Mobility & Freedom Freedom is at the core of Luisa’s design. Weighing just 3.8 kg, it is exceptionally lightweight for a life-support device. The integrated battery provides a runtime of up to 6 hours, which can be extended to 18 hours with optional external batteries, giving users the confidence to travel, go to school, or enjoy day trips without worrying about power.
Versatile Therapy (High Flow & Ventilation) Luisa is a true all-rounder, supporting all common ventilation modes for invasive and non-invasive therapy. A standout feature is the integrated High-Flow Oxygen Therapy (HFT) mode, which allows patients to switch between standard ventilation and High-Flow therapy using the same circuit—no adapter changes required. It is suitable for a wide range of patients, from adults down to small pediatric patients (starting at 30ml tidal volume).
Intuitive Control The device features a brilliant 10-inch angled touchscreen that makes navigation as simple as using a smartphone. The menu is clear and user-friendly, providing detailed monitoring data and alarms without overwhelming the user. With advanced connectivity (Bluetooth/Cloud), therapy data can be easily shared with care providers.
