Medical guidance when altitude affects your plans
Expert guidance for altitude-related symptoms, oxygen use, and high-altitude wellness—led by board-certified emergency physician Kirk Mahon, MD.
Even healthy travelers can feel the effects of Aspen’s elevation. When symptoms interrupt your trip, it can be difficult to know what is expected, what may help, and when to seek care.
Oxygen Now combines physician-led guidance with local oxygen coordination. Our team can help you discuss your symptoms, understand available options, and arrange prescribed oxygen equipment for your hotel, residence, or vacation rental when appropriate.
Symptoms at altitude can have many causes. Personalized medical guidance can help determine the appropriate next step.

Read about altitude sicknessCan I speak with a physician about altitude symptoms in Aspen?

Know when to seek emergency care
Some symptoms should not wait.
Call 911 immediately for severe shortness of breath at rest, chest pain, confusion, fainting, blue or gray lips or skin, inability to walk normally, or rapidly worsening symptoms. Oxygen Now is not an emergency service and supplemental oxygen is not a substitute for urgent medical evaluation.
