[Monitoring of respiration at night. Evaluation of a microprocessor-based system for cellection, analysis and presentation of respiratory parameters].

Spirolab, a microprocessor-based system, intended for collection, analysis and presentation of respiratory parameters was validated by comparing measurements in the oesophagus end stomach with changes of resistance in strain-gauges placed on the thorax and abdomen. It was also shown that temperature changes can be used for monitoring airflow. The limitations of the methods are discussed. Spirolab and its monitoring methods have proven suitable and valid in the diagnosis and control of treatment of patients with nocturnal respiratory disorders.
