Safety Questions
Q:  How safe is altitude training?

A:  Altitude training is all about adapting to high altitude, which is a natural physical ability of humans.  
Many people travel to and from high altitude for recreation every year without ill effect.  Millions more live
year-round at high altitude.  Few of us would be concerned about taking a vacation in the Alps, or going
skiing in the Rockies.  Even commercial jets for the general public are pressurized only to the
equivalent of 8000 feet.  This is not to say there are no risks, especially if you are not in good physical
condition or try to acclimate too quickly.  People going to high altitude sometimes experience mild
“mountain sickness” symptoms such as headache, fatigue, difficulty sleeping, and dehydration.  These
symptoms should subside as the body adjusts to altitude.

Q:  Who should NOT use altitude training?

A:  You should not attempt altitude training if you have cardiac or pulmonary conditions, hemoglobin
abnormalities, diabetes mellitus, hypertension, epilepsy, severe obesity, kidney disease, if you are
pregnant, or if you are immune-suppressed, unless specifically cleared by your doctor.

Q:  Could there be medical complications?

A:  Altitude training typically takes place at high altitude (8,000 to 12,000 feet), not at the altitudes
associated with extreme mountaineering where the risk of medical complications are  higher.  

Some of the possible complications of high altitude (though NOT necessarily associated with
simulated altitude training) include acute mountain sickness, pulmonary edema, cardiac arrhythmia,
cerebral hypoxia, hypercoagulability, and possibly a degree of immune suppression.

Severe symptoms (persistent severe headache, nausea, difficulty breathing) require an immediate
return to normal altitude.   We encourage everyone going to altitude or using simulated altitude
training to learn about Acute Mountain Sickness and know how to recognize and react to the
symptoms of AMS.

Q:  What are the safety features of the Mountain Air Generator ?

A:  The Mountain Air Generator uses a proven, safe method of producing low-oxygen air:

  • No chemicals or additional gases.  The only ingredients are electricity and air.
  • Room-pressure system; there are no vacuums or pressurized chambers
  • Masks provided with the MAG have safety vents that assure you will always be able to get air in
    case of power failure or other interruption of air flow
  • Due to filtering, the air produced by the MAG is many times cleaner than normal room air
  • An optional oxygen monitor to make sure you do not fall below the intended oxygen
    concentration
  • The air is never recycled -- fresh air is continuously used
  • Fail-safe design -- if power fails or any internal component fails, the MAG will either stop
    producing low-oxygen air, produce a reduced flow, or produce air with higher oxygen content

Finally, a little common sense -- never, never put yourself in a situation where you could suffocate if
the airflow from the MAG is stopped due to power failure or mechanical failure.  Our masks have a
safety vent, so you will be safe even if there is a power failure.
