SE-RDA Respiratory Data Analyser

Description

Real-time recording of breathing

Quantitative measuring of mask wearer’s breathing

The SE-RDA is a portable instrument that analyses real-time respiratory flow rate and air pressure inside a respirator while fitted to a person. The device is used on location during normal work, continuously recording each breath at a rate of 50 samples per second for up to 12 hours.

Features

  • Captures multiple breathing parameters in real time.
  • Can be used to measure human breathing during any activity.
  • Monitoring can be done on negative-pressure masks, PAPR and breathing apparatus.
  • Does not affect breathing resistance or interfere with the airflow through the mask.
  • No advanced technical skills required.
  • Powered by three AAA batteries.
  • Can be connected to Sundström masks without any permanent modifications.
  • Can assess the performance of Powered Air-Purifying Respirators (PAPR).
  • Download collected data to computer

  • Description: The SE-RDA is a portable instrument that analyses real-time respiratory flow rate and air pressure inside a respirator while fitted to a person performing normal work routines
  • Range of devices: Can be connected to negative-pressure devices with filters and positive-pressure respirators such as Powered Air-Purifying Respirators (PAPR) and breathing apparatus. Can be connected to Sundström full face and half face masks without any modifications
  • Sampling: Captures multiple breathing parameters in real time at a rate of 50 times per second for up to 12 hours
  • Software app: Comprehensive software app included. The app enables the user to determine:
    • Minute volumes (averaged over an entire shift or selected periods)
    • Total volume breathed
    • Peak inhalation flowrates for all tasks performed during the period
    • Breathing Resistance (BR) and Work of Breathing (WoB) for various types of RPD
    • ISO Work Rate classification (W1 – W4) and how the work rate varies over the period
    • The amount of time the respirator is worn during the shift.
  • Battery: 3 x AAA batteries
  • Dimensions: 127H x 78W x 26D mm — pocket clip on back. Connectors extend approx. 8 mm from housing
  • Weight: 126 g
