Oxygen (O2) is the main fuel for the body.

You are watching: 6 liters of oxygen is what percentage

Every organ requirements O2 to work. Just like gas because that a car, if your body’s O2 level is also low, your organs i will not ~ work. Girlfriend won’t have the ability to think clearly, your heart might not be able to pump as well, your kidneys will certainly not be able to filter and also clean her blood effectively, etc. Yet unlike gas because that a car, O2 is no just vital for your body to perform. If a car runs out of gas it stop running. But it walk not start to autumn apart. It simply sits there unable to move. If her body O2 level gets too low your organs begin to in reality shut down and even start to be injured by lack of oxygen. Eventually, your organs have the right to be permanently damaged or also die if O2 is low enough, lengthy enough.

Patients with progressed chronic lung disease often have low blood O2 levels. If that is severely low, they acquire distressed and need prompt aggressive medical attention. Yet if that is mildly, or also moderately low, patients can frequently function, though generally not optimally. Many times patients with mild to moderately short oxygen feeling bad. But occasionally they don’t, or at the very least they are not mindful that they might be emotion much better if their oxygen to be good.

We recognize from clinical studies that advanced lung disease patients with low O2, characterized as a blood oxygen saturation of below 90%, advantage greatly by making use of supplemental O2 gas. In fact, these patient live substantially longer if they usage O2 for at the very least 15 hours per day. As you might expect, hypoxemic patients (patients through low blood oxygen) feel better, space able to perform more, and in general have far better health, through oxygen use. So the is why doctors prescribe O2 because that patients with advanced lung condition and short O2.

Oxygen is non-addictive. the is, making use of O2 does not make her lungs weak, or dependent ~ above the O2.

O2 usage is really rather safe in general, but there are some straightforward precautions to take with clinical O2 in the home. First, that is really important to understand that O2 is flammable. For this reason fire and also ignition materials should be maintained out of the instant vicinity (at least 5 feet) of one O2 gas source. Naked wires or other fire hazards, as well, should be retained away native oxygen. Second, O2 shipment systems must be maintained in fine ventilated areas. By act so, over there is very small risk of elevating the oxygen content of a room or building significantly, or enough to increase the possibility of a general fire.

Oxygen for patients is normally ordered by doctors for patients meeting criteria, and delivered to the patient by a clinical oxygen it is provided company. Virtually universally, patients inhale the O2 gas indigenous a “nasal cannula”. small tubing that delivers O2 into the nostrils. The gas travels up through the nose and then down right into the back of the throat whereby it is inhaled without any type of conscious effort by the patient. Simply normal breathing brings the extra oxygen into the lungs. The tube is hooked up to one of several varieties of O2 gas it is provided sources. The O2 can come from a tank of concentrated oxygen, an oxygen concentrator, or from fluid oxygen.


Concentrated O2 gas – this is the oldest mechanism of O2 because that the home. Compressed O2 gas come in various sized steel canisters. Huge canisters are for use in the home and small canisters have the right to be taken portable. The gas is permit out right into the oxygen tubing through a valve, with a “flow regulator” the determines just how much comes the end of the tank in liters per minute. Brand-new tanks get yielded to the residence when the old tanks run low top top O2.Liquid oxygen – these solution run on fluid oxygen. A storage tank is refilled periodically with cold oxygen – i m sorry is in liquid form. Once warmed up the fluid O2 turns right into a gas that have the right to come out of tubing. There are now portable systems that usage liquid O2. They are the lightest the the portable O2 systems.Oxygen Concentrator – this mechanism runs top top electricity. It traction oxygen indigenous the air and concentrates it to be let out right into the oxygen tubing that goes come the patients. Traditionally this has been a workhorse of home O2. Newly light weight, battery activate systems have come the end for portable use. This systems do not should be serviced through O2 gas or fluid oxygen.


The O2 gas circulation to sleep cannula have the right to come native the oxygen resource as continual flow, or intermittent flow. The usual method to provide O2 is a regular flow indigenous the source. Because that example, a usual continual circulation rate that gas through the nasal cannula is 2 liters of O2 gas every minute. This is happening with all components of the respiratory cycle, even when patients are not breathing in. This may seem garbage to have actually O2 flowing as soon as not breath in. Indeed, some of the O2 gas goes into the surrounding air. Yet also, some of the O2 gas, in between breathes, goes into the nose and upper airway, and also forms a “reservoir that oxygen”. As soon as the patience does take a breath, a greater concentration the O2 is inhaled from this reservoir, in enhancement to the O2 from active flow. Intermittent O2 gas flow is designed to maintain O2 gas, particularly for the portable systems, that have actually a restricted O2 supply, or a limited battery life. There are several types of intermittent circulation systems, yet they all deliver O2 flow timed come inspiration. Theoretically the intermittent circulation O2 systems can do as great a job at offering O2 as the constant systems. The truth is, though, that numerous patients just don’t do too with the intermittent system.

The circulation rate o f oxygen is usually adjusted to boost or diminish the lot of oxygen the patients space receiving. Typical oxygen sources can supply from ½ liter every minute that O2 come 5 liters/minute (L/min). Every liter/minute that oxygen increases the portion of O2 the patient breathes through 3 – 4 %. Room waiting is 21% O2. Therefore if a patience is on 4 L/min O2 flow, climate he or she is breath air the is around 33 – 37% O2. The normal exercise is to change O2 flow for patients to be comfortably over an oxygen blood saturation that 90% at rest. It is often, however, the situation that patient need much more oxygen for exercise. Therefore for example a patient may use 2 L/min O2 at rest, but need 4 L/min v exertion.

Occasionally, for patients needing high circulation rates we take into consideration two other devices to boosts the quantity of oxygen a patient have the right to get. One is an “oximizer”. These tools are, essentially, mini O2 reservoirs, the hang off the nasal cannula, and permit the patience a larger source of potential oxygen once taking a deep breath. A “transtracheal oxygen cannula” is a cannula, placed straight into the trachea that delivers O2 gas. The cannula is placed through a small tunnel created by an ENT surgeon, with the former of the neck, straight into the main breathing tube referred to as the trachea. These tools have to be frought through complications and our practice, go not use them any kind of longer.

Lastly, numerous patients don’t like to be viewed wearing oxygen. They uncover it embarrassing, and fear it to be socially isolating. Well, it is where attitude makes every the difference. Think of oxygen as just one more tool in your tool belt to execute what you have to do. Few of us need drugs to carry out what we must do, some require a knee brace. Us all require cars, busses, or trains to acquire around. Well oxygen is simply gas because that the car, in some lung diseases. Don’t let O2 border you, let it take you wherein you desire to go.
