Scala – The Interesting Features

Scala has a number of special features that make it attractive to a wide range of users. Among other things, it offers the possibility to derive additional signals such as ECG or EMG via integrated electrophysiological inputs. In addition to measuring airflow using a differential pressure nasal cannula, the device also offers the option to measure the patient’s respiratory airflow with a thermistor.

Unbeatable Functionality

A sensor for snoring detection can be applied to the patient’s throat. The integrated differential pressure measurement for monitoring PAP and NIV therapies ensures high-quality detection of the flow signal, especially at high and rapidly changing pressures.

In addition to pressure pad technology, Scala allows parallel or alternative recording of respiratory movements using induction belts (RIP).

Electrode Inputs – Freely Configurable

Four freely configurable electrode connection ports can be used for various electrophysiological tracings such as EMG, ECG, or EEG.

Online and Offline Operation

Scala supports both traditional offline measurement and online measurement. An optional WLAN variant enables both wired and wireless data transmission from the patient recorder to a computer.

Time-synchronized recording of video and audio signals is possible, as well as synchronized integration of external analog signals from therapy devices or transcutaneous CO₂ monitors.
