Cardio Respiratory

A new investigative tool for “holter-style” recording of a wide range of physiological data. Somté software provides comprehensive analyses to assist in understanding the nature and severity of the interrelated respiratory and cardiac diseases.

Product Features


The best in digital technology
Somté is the crystallization of Compumedics’ years of experience and technological expertise in producing amplifiers and sensors for capturing physiologic data.We selected the best measurement techniques for tracking cardiac and respiratory physiology and packaged them into Somté. This includes:

  • Integrated pressure transducer for nasal flow signal/derived snoring/CPAP pressure.
  • Respiratory bands that utilize inductive technology for semi-quantitative recordings
  • 2 channel ECG with full disclosure
  • Integrated oximeter with pulse waveform

Superior signal recording
The Somté is a compact pager-sized recorder with remarkable features:

  • Integrated, high resolution LCD display for convenient control and monitoring functions
  • Three-button user-friendly operations
  • High capacity data storage on a removable Compact Flash Card
  • Powered by 2 AA batteries (Alkaline or NiMH) for portability
  • Small, patient wearable, unobtrusive and light weight: system weighs only 200 grams

Remarkable features in a compact recorder
Somté offers versatility and customization with 8 data channels producing up to 13 total signals including data types not typically offered on small, ambulatory recorders.

  • Your choice of 2 available high frequency channels – EEG, EOG, ECG or EMG
  • Up to 2 channels of ECG for arrhythmia detection and classification
  • Multiple ECG waveform view
  • Pressure transducer for sensitive nasal airflow and CPAP measurements
  • Effort signals produced from inductive band technology
  • PLM data collection/ analysis

Available signals

  • EXG 1 (EOG, EEG, EMG, ECG, Off)
  • EXG 2 (EOG, EEG, EMG, ECG, Off)
  • Pressure
  • Airflow
  • Snore
  • Thoracic Effort
  • Abdominal Effort
  • Limb movement
  • Body position
  • SpO2
  • Pulse rate
  • Pulse waveform
