Lastly, historic hypoxia occurs at the cell level when the cells that require oxygen is impaired and thus cannot use. The latter kind of hypoxia occurs when a body is exposed to cold temperature, resulting in low blood flow intensity. When the blood flow is decreased, the heart will fail to pump the blood effectively. When there is any compromise in the blood flow, there will be no enough oxygen to get into the body tissues. Likewise, stagnant hypoxia happens at the circulatory level. It may be caused by nitrites, hemoglobin abnormalities, hemorrhage or anemia. Hypemic hypoxia occurs when the blood is not able to carry enough oxygen. Additionally, there is the lower pressure of oxygen at that level, therefore, human lungs are not be able to transfer oxygen from the air to the blood. The pressure of oxygen in the air decreases when pilots reach certain altitude. When altitude increases, oxygen molecules in the ambient air get apart and exert less pressure. Hypoxic hypoxia is experienced by the pilots when they fly at altitude in an aircraft that is unpressurized. Consequences of Different Types of Hypoxia in Aviation The final report of the National Transport Safety Board named the cause of the accident to be the in-flight impairment of the pilot due to hypoxia, as he operated without supplemental oxygen hence, causing him to lose control. It was then that the pilot became hypoxic, as evidenced by meandering flight path recorded by the air traffic controller. In this particular flight, the pilot was flying at 14,800 feet MSL after flying for about 40 minutes and without using any supplemental oxygen. For instance, the Cessna T182 of Ludlow California serves as a proper example. If proper measures are not laid out, there is a high probability for air crash. It is at such high altitudes that supplemental oxygen becomes a necessary component, especially at heights of above 12500 feet MSL. Indeed, hypoxia is a progressive condition that is not easily detected as one slowly lapses into incompetence, while remaining at euphoric faith in one’s own abilities. According to the federal aviation administration, the higher one flies, the less the air in the sky. The brain, despite constituting a small portion of the body, consumes 25% of oxygen and, hence, requires a constant supply of it. By taking in oxygen the stores of energy in the form of Adenosine Triphosphate (ATP) in the body cells get replenished. All first-time users will automatically receiveīreathable air comprises of approximately 20.95% of oxygen.
