High flow oxygen therapy

For Your Ventilator Patients

The LUISA, with High Flow Therapy (HFT), is a home ventilator that offers all the potential benefits of HFT for patients that meet the clinical requirements for home ventilation. High Flow Therapy can deliver a high flow blend of air and oxygen, through a high-flow nasal cannula, which can improve oxygenation and decrease the workload of breathing in a wide array of patient populations.3

High Flow Therapy has been used in critical care, emergency departments, and is now available to the ventilator patient at home.

High Flow Therapy provides a flow rate that meets or exceeds a patient’s inspiratory flow demand. This high flow rate can reduce the work of breathing and more closely match inspiratory demand through adjustable oxygen delivery and flow dependent clearance of carbon dioxide.4,5

High Flow Therapy that's

Easy to Use

LUISA has the potential to help manage nocturnally ventilated patients during the day with a less obtrusive oxygen flow delivery method that can potentially lead to:

Enhanced oxygenation compared to conventional low-flow oxygenation4

Improved work of breathing5

Better secretion clearance5

Increase in activities of daily living like eating, drinking and talking5

Superior comfort and less anxiety or claustrophobia which could lead to better compliance6

The LUISA provides the flexibility of High Flow Oxygen Therapy, for your patients that meet clinical requirements for home ventilation, in all circuits with a flow range of 5-60 lpm.

LUISA offers all the benefits of High Flow Therapy for your ventilator patients in one device at home.

Tailored Therapy

LUISA provides ventilator support and utilizes all standard volume, pressure and mouthpiece ventilation modes with the added benefit of High Flow Therapy. Ventilator modes include LUISA’s targeted tidal volume, volume-assured pressure support, auto EPAP (TTV-VAPS-AE).


Internal and external batteries offer long-lasting battery life with up to 18 hours of use. LUISA is a lightweight and portable ventilator that offers two position functionality for flexibility of use at bedside, in an easy-to-carry durable bag or mounted on a wheelchair.

Ease of Use

The LUISA is designed for simple set-up and operation. A large, angled and rotatable 10-inch touchscreen provides an easy to view screen when programming the device through its’ intuitive menu. It also provides easy visibility for patients from many angles while in use. The LUISA is a multi-purpose ventilator that does not require any adapters for different circuits.

Personalized reports

Device connectivity allows for personalized therapy data downloads. The customized reports provide essential information to manage your respiratory patients and ensure they are maximizing their therapy.

We make it easy

Service Simplified


LUISA with High Flow Therapy provides long term care with easy serviceability. Routine patient maintenance consisting of only filter changes and a device wipe down provides uncomplicated upkeep.

With simple, routine maintenance and no adapters required between circuits, the LUISA provides clinicians and patients peace of mind with an all-encompassing system in a compact, home ventilator with the added benefit of High Flow Therapy.
