RespiHeart is based on optical measurement, using two different wavelengths. The geometrical design of the sensor enables deep bone level penetration. The light from the sensor illuminates the sternum blood vessels and the detectors capture the reflected and scattered light.

Based on the unique respiration signal, RespiHeart offers unique advantages and diagnostic opportunities

New Respiratory Parameters

  • Respiratory arrhythmias

  • Inspiratory reserve capacity, IRC

  • Expiratory reserve capacity, ERC

  • Relationship: inspiration time / Expiration time

  • Obstruction

  • Variations in respiratory depth

  • Respiratory related variations in oxygen saturation

The RespiHeart signal corresponds to variations in respiratory pattern reflecting irregulatories and dyspnea in breathing

The inspiration / expiration slope provides a measure of respiratory obstruction
