The EMPU has its very own in-house built breathing simulator (also known as a metabolic simulator). It can simulate a person's breathing by taking in air and exhaling warm, moist CO2 —just like a breath—and can operate at a full range of altitudes and depths.
Its functionality is for testing breathing equipment such as SCUBA (SCBA) and closed-circuit rebreathers (CCR), and its oxygen consumption and carbon dioxide production are to match minute ventilations, i.e. up to 4.5 and 5.0 L/min STPD, respectively.
|Tidal Volume:||0.5 L to 3.5 L|
|Breathing Frequency:||Up to 50 breaths/min|
|Minute Ventilations:||From rest to extreme exercise, up to 150 L/minute. These can match settings used in diving (e.g. US Navy, EN 250, EN 14143, EN 15333), or by organizations like ISO and NIOSH|
The EMPU provides hot and cold immersion testing. Our wet pot can accommodate one person and a bicycle ergometer, one person with a swimming ergometer, or multiple people. The wet pot can be chilled or heated to various specifications for survival, immersion, dry, semi dry and wetsuit testing.
