As a standard practice the effective& preventative travel insurance measure to treat AMS is to attain a lower altitude slowly, However If attaining lower altitude is not possible immediately, a Portable Altitude Chamber can come in handy which will help increase the air pressure and stimulate conditions that prevail in lower altitude. Also climbing or traveling must happen in installments of small journeys with good breaks in between. So the entire trip gets spread onto some more days or weeks if necessary.
