Do You Need Oxygen at 35000 Feet?
At 35,000 feet, the atmospheric pressure is much lower than it is at sea level. This means that the air contains less oxygen than it would at sea level. For this reason, it is recommended that anyone travelling above 35,000 feet use supplemental oxygen.
Atmospheric Pressure
Atmospheric pressure is the force of air molecules pressing down on the Earth’s surface. At sea level, the atmospheric pressure is around 14.7 psi (pounds per square inch). As you ascend in altitude, the atmospheric pressure drops. At 35,000 feet, the atmospheric pressure is only 4.3 psi.
Oxygen Levels
At sea level, the air contains approximately 21% oxygen. At 35,000 feet, the air contains only about 14% oxygen. This means that there is significantly less oxygen available to breathe at 35,000 feet than there is at sea level.
Supplemental Oxygen
Because of the reduced oxygen levels at 35,000 feet, anyone travelling above this altitude should use supplemental oxygen. Supplemental oxygen can be provided through a variety of sources, including oxygen tanks, oxygen concentrators, and oxygen masks. Using supplemental oxygen ensures that the person travelling above 35,000 feet is getting the oxygen they need to stay safe and healthy.
Altitude Sickness
Altitude sickness is a condition that can occur when a person ascends to high altitudes too quickly. Symptoms of altitude sickness include headaches, nausea, fatigue, and shortness of breath. At 35,000 feet, the air pressure is such that altitude sickness can occur quickly. Using supplemental oxygen can help to prevent altitude sickness.
In conclusion, anyone travelling above 35,000 feet should use supplemental oxygen to make sure they are getting the oxygen they need. Without supplemental oxygen, the person may be at risk of altitude sickness and other health complications.
