Therapy information
CPAP mode
In CPAP mode, a fixed pressure is delivered.
Bilevel modes
The Lumis device assists spontaneous breathing by cycling between two pressures in response to
the patient flow or a preset fixed time.
The inspiratory positive airway pressure (IPAP, or the sum of EPAP and the pressure support level)
assists inspiration.
The lower expiratory positive airway pressure (EPAP) facilitates exhalation comfort while providing a
splint to maintain an open upper airway.
The difference of the two pressures—pressure support (PS) level—contributes to improved patient
ventilation.
S (Spontaneous) mode
In S mode, you may set two treatment pressures-–one for inspiration (IPAP) and one for expiration
(EPAP). The device senses when the patient is inhaling and exhaling and supplies the pressures
accordingly. The difference between IPAP and EPAP levels helps determine the tidal volume.
ST (Spontaneous/Timed) mode
In ST mode, the device augments any breath initiated by the patient, but will also supply additional
breaths should the patient breath rate fall below the set Backup Rate.
T (Timed) mode
In T mode, a fixed breath rate and a fixed inspiration/expiration time are supplied regardless of
patient effort.
PAC (Pressure Assist Control) mode
The inspiration time is preset in the PAC mode. There is no spontaneous/flow cycling. The
inspiration can be triggered by the patient when respiratory rate is above a preset value, or time
triggered breath will be delivered at the set Backup Rate.
iVAPS (intelligent Volume Assured Pressure Support) mode
iVAPS is designed to maintain a preset target alveolar minute ventilation by monitoring delivered
ventilation, adjusting the pressure support and providing an intelligent backup breath automatically.
The iVAPS therapy mode is indicated for patients weighing 66 lb (30 kg) and above.
