TheDescentPart2ItaYoutubeHypoxia Its Not About Breathing. I recently sat in a room full of aviation professionals and, unbelievably, heard the comment that the so called oxygen bottle is really compressed air, just like scuba divers use. While I sat there with my mouth open, more than a few in the room nodded agreement. They may not be the only folks thinking this to be true. In the early 1. 98. Gulfstream GIII. Wed occasionally fly the airplane at FL 4. Today, FL 4. 50 is a given on most any long eastbound flight and we often see the other corporates heading west at FL 4. While I once got to 5. F4. E ask me sometime, I wouldnt fly any of todays equipment above FL 4. High altitude flight is so comfortable, and so routine, that the perils of that realm of flight are overlooked in the hours of sheer boredom. Recent events show that when the shell on that artificial world is broken, reaction has to be instinctive or people will die. Oxygen being delivered to the human brain by the bloodstream is vital for normal cognitive functioning, Beyond that, it is required for sustaining life. But did you know there are altitudes at which you could be sitting in a passenger seat of a jet with the passenger oxygen mask on your face, with the system functioning normally and delivering 1. Its not about breathing, its about gas transfer. In this case that gas is oxygen. Lack of such a transfer, oxygen deficiency, is called hypoxia. Some Terms. Hypoxia Lack of oxygen to the brain. There are four types a. The Descent Part 2 Ita Youtube DownloaderHypoxic Not enough oxygen is available. Hypemic The inability of a persons cells to carry sufficient oxygen due to another chemical compound think carbon monoxide being more readily transferred into them than oxygen. Histotoxic The inability of the blood cells to carry sufficient quantities of oxygen because they are overloaded with other chemicals such as alcohol. Stagnant Lack of oxygen to the brain due to blood being drawn from the head due to external forces gs. In this article, we will discuss only hypoxic hypoxia. Hyperventilation A condition in which too much oxygen in the bloodstream causes panting, which increases oxygen, causing more panting until the amount of oxygen is large enough to create syncope. Syncope, passing out, is the bodys way of saying slow down. Evolved Gases Disorders Problems in the body due to nitrogen in the blood coming out of solution at locations other than the lungs.

In this case, lets think of it as the transfer that occurs when oxygen passes from the atmosphere into the bloodstream through the membranes of the lungs, called alveoli. Daltons Law This law states that the partial pressure of a gas in a considered atmosphere is equal to the percentage of the total mixture of gases in that atmosphere that the given gas represents. Time of Useful Consciousness TUC How long the brain can be deprived of oxygen and still be able to make useful decisions and complete complex tasks such as piloting an airplane. Oxygen makes up about 2. Nitrogen makes up about 7. Leaving inert gases out of the equation changes nothing and makes the math easier. So, our assumed atmosphere is made up of oxygen and nitrogen at the ratio of 8. At sea level, the atmospheric pressure is 1. Daltons law, we receive oxygen at a partial pressure of about 3 psi 0.

While hypoxia is a decrease in the amount of oxygen getting into the blood and into the brain, the tissues and the cells, it doesnt have to be a fatal decrease. Game Maker Check If Object Room. We took a cog railway trip to the top of Pikes Peak a few years back and I had to guide my wife through the gift shop by the shoulder. She was having a ball more on that later, enjoying her inability to coordinate her movements normally. She was tipsy, eventually became belligerent were blaming hypoxia and wound up just wanting to take a short break. All of these moods are classic hypoxia symptoms. She literally improved each few hundred yards of the trip back down the mountain and was normal when we reached the base or as normal as a sea level person could be at nearly 7,0. MSL. She was suffering some of the effects of hypoxia, but at that altitude they would not be fatal for the time she was there. We can all understand that when we put on an oxygen mask that is sealed to our face no beards allowed, if that mask selector switch is in 1.

It is more instructive to discuss what the regulator does for the pilot in the normal position. How much oxygen are we receiving sitting on the ground How about at altitudes like 1. Lets assume the oxygen regulator has been designed to produce oxygen at a partial pressure of 3. At sea level thats the pressure that already exists, so the regulator, in normal, delivers ambient air to the pilot at a cabin altitude of sea level. This is why I used to smile when I heard certain European inspectors would check the oxygen remaining to insure crews had oxygen masks on when above FL 3. At the cabin altitude that a properly functioning pressurization system would provide at FL 3. At 1. 0,0. 00 ft., atmospheric pressure is equal to 1. Lets assume that 2. This is why cockpit warnings come on around the 9,0. They are saying Do something or youre going to feel like Detwilers wife on top of Pikes Peak, and shortly after that even worse things may happen. For normal functioning, we need 3. How can that be achieved if the total atmospheric pressure of the atmosphere at that altitude is only 1. Its simple. The design of the regulator changes the mixture of oxygen with ambient air so that at that altitude the amount of the oxygen being delivered is raised to roughly 2. This means there is still enough oxygen in the mixture for the partial pressure of that oxygen to allow normal transfer. An altitude of 1. Atmospheric pressure at that altitude is equal to 6. If Im losing you here, go back to the discussion of Daltons law, on the previous page. At 3. 5,0. 00 ft., the total pressure of the atmosphere is about 3. In order for normal oxygen transfer to occur, we know oxygen must be present at about 3 psi. Since the total atmospheric pressure at 3. In the above senerio an interesting phenomenon occurs. The total pressure of the atmosphere goes below 3. So, even with 1. 00 of the mixture presented to the pilot being oxygen, there will not be enough partial pressure of oxygen at the alveoli to make a normal transfer. The regulator must start delivering pressurized oxygen to the pilot. Pressure breathing has to have been practiced. When used to the procedure, its actually fun to force the air out of your lungs, like you are blowing up a balloon, and then relax and let the regulator pressure fill your lungs back up. Almost everyone will hyperventilate the first time they try it, especially if they are under stress at the time. Pressure breathing will allow the pilot to function into the low to mid 4. When these gases, mostly nitrogen, bubble out and collect around the joints, its called the bends. The military requires that full pressure suits be worn for flight above 5. Factors Affecting Hypoxia. The most common factor affecting ones ability to become hypoxic is the physical condition of the pilot involved.
