1.1 Intended use
The BiLevel ST 22 is a home breathing apparatus for non-invasive, non-life-saving
ventilation of adult patients with respiratory insufficiency, but who are evidently able
to breathe independently. This is in keeping with the following clinical scenarios:
• restrictive and obstructive ventilation problems, e.g. OSAS, COPD,
obesitas hypoventilation syndrome
• Problems with the mechanics of breathing, e.g. scoliosis or a chest
deformity
• neurological, muscular and neuromuscular problems, e.g.
diaphragmatic paresis
• Central respiratory regulation disturbances
BiLevel ST 22 is not designed for life-support .
Only use the unit for the purposes described here.
1.2 User qualification
The settings on BiLevel ST 22 may only be set by a doctor and to suit the individual
patient.
When handing over BiLevel ST 22 to the patient, the doctor treating the patient or
the clinic staff must instruct the patient on how the unit works.
1.3 Functional description
Preparing the therapy pressure
An electronically controlled fan draws in ambient air via a filter and conveys it to the
unit outlet. From here the air flows through the hose system and the nasal mask to the
patient.
