1. Introduction
1.1. Assigned Purpose:
The MiniScreen plus and MiniScreen premium Sleep
Diagnosis Systems are recording systems for use in
professional health care environment. They serve as
a differentiated pre-diagnosis for the sleep apnea
syndrome and enable continuous recording of up to
40 channels for at least 15 hours without loss of data.
The recording of data on battery power is also
permitted in home care environment.
They record signals for the following physiological
variables:
•
Flow
•
Oxygen saturation SpO
2
•
Pulse frequency
•
Pulse wave
•
Body position
•
Respiratory and snoring sounds
•
PAP (Positive Airway Pressure)
•
Ambient Light
•
Thorax effort
•
Abdomen effort
•
Breathing frequency
•
Phase shift Thorax Abdomen
optional:
•
Thermistor
•
ECG
•
Central heart Frequency
•
PTT (Pulse Transit Time)
•
Systolic Blood Pressure (Trend)
•
Leg movement (LEG)
•
EEG (Neuroport, only MiniScreen plus)
•
