What is hyperbaric oxygen therapy?
Hyperbaric oxygen therapy uses a special pressurized chamber to deliver 100% pure oxygen to your lungs. You go to a medical facility for this outpatient treatment.
Increased air pressure inside the chamber helps your lungs take in more oxygen. This extra oxygen can aid the healing of wounds, burns and infections.
Scuba divers and high-altitude mountain climbers may need HBOT if they develop decompression sickness . The condition occurs when too much nitrogen builds up in your blood and tissues.
A note from Cleveland Clinic
Oxygen therapy can be a lifesaving medical treatment when lung problems prevent you from taking in enough oxygen when you breathe. You may need supplemental oxygen all day, every day or just some of the time. Your healthcare provider can review the types of oxygen therapy delivery systems with you, so you can choose the one that best meets your needs. Its critical to follow certain safety measures when you use oxygen therapy.

How To Treat Exercise
Whether your goal is to improve performance or start exercising for better health, there are things you can do to improve symptoms of exercise-induced bronchoconstriction naturally.
You may already be aware of natural remedies that focus on diet, weight-reduction, and physical fitness. You may also be careful to avoid triggers. If your trigger is exercise, however, and you want to stay fit and well, this presents a catch-22 situation.
Since asthma is a condition that affects breathing, it makes sense to look to breathing to resolve it. Asthma often exists alongside dysfunctional breathing patterns. As weve seen, it can flare up when you over-breathe or breathe through an open mouth. Clinical trials have shown that breathing exercises can help reduce and prevent asthma symptoms. They can even be used to stop an asthma attack.
Heres what to do to rid yourself of symptoms:
Reactive Airways Dysfunction Syndrome
Reactive airways dysfunction syndrome is a rapid onset and persistent asthma-like disorder that occurs in people with no history of asthma. It is a form of environmental lung disease caused by a single large exposure to nitrogen oxide or volatile organic compounds . People have symptoms similar to those of asthma, including cough, wheezing, and shortness of breath. Treatment is similar to usual treatment for asthma.

Myth : I Do Not Need To Take My Inhalers When I Feel Okay
The National Heart, Lung, and Blood Institute strongly recommends taking your long-term control medications each day.1 Asthma is a chronic inflammatory disease. This means that even when you do not have any asthma symptoms, your airways are still inflamed. Long-term control medications reduce the inflammation. With less inflammation, your airways become less sensitive. This prevents symptoms from flaring up, improves your lung function, and reduces the risk of complications.1
It can be hard to remember or want to take your medication when you are feeling fine. Work with your health care provider to find the lowest dose you need to control your symptoms. Make taking your medication part of your daily routine, for example, before you brush your teeth in the morning or when you sit down to eat breakfast. Store your medication in the same place every time. One study showed that people were more likely to take their inhaler if it was stored in the bathroom instead of next to the bed.7
Treatment Goals: Open Constricted Airways Dry Secretions And Reduce Inflammation
Nebulized albuterol, connected to oxygen at 6-8 LPM, is the first EMS treatment for asthma. Albuterol stimulates beta-2 receptor sites to causes rapid bronchodilation. Ipratropium bromide can be mixed with albuterol in a nebulizer, which causes bronchodilation and inhibits mucus secretion by inhibiting the vagal response. Both can be administered until the patients symptoms improve .
Corticosteroids decrease inflammation from an asthma attack. Methylprednisolone can be administered intravenously or intramuscularly, and prednisone can be administered orally. The onset for both medications is four to six hours, so they should be administered along with bronchodilators and deferred if urgent airway management is needed . Despite the long onset of action, one study found in-hospital delays of steroid administration to asthma patients, and a lower hospital admission rate among patients who received methylprednisolone from EMS .
CPAP is a treatment option for moderate to severe asthma attacks. CPAP increases the pressure that the patient exhales against, which pushes open lower airways and improves gas exchange . Nebulized bronchodilators should be administered through CPAP, which provides an air-tight seal to help direct medication into the lower airways.
Magnesium sulfate may help patients with severe asthma attacks in addition to nebulized bronchodilators and CPAP. It works by relaxing smooth bronchial muscles, and is administered as an IV infusion over 20 minutes .

When To Contact A Doctor
Asthma can be life threatening for a child, so it is very important that a person seeks medical attention if a child starts to show symptoms of asthma.
A medical professional will then be able to offer advice on the best methods available to manage the condition.
It is also vital that a person seeks immediate medical help if they experience oxygen deprivation. Symptoms of this can include:
Oxygen Therapy And Copd
People with COPD have different pathophysiology compared with those with asthma. In particular, people with COPD often experience exacerbations with decreasing lung function after each episode .
An exacerbation is the sustained worsening of patients symptoms such as breathlessness, cough, increased sputum production and change in sputum colour .
The outcomes for these patients can be catastrophic after hospital discharge, with 34% being readmitted and 14%dying within three months .
In patients with COPD who are experiencing an exacerbation, the guidance recommends that they be given oxygen therapy via a venturi mask at either 28% with flow rate of 4L per minute or 24% with a flow rate of 2L per minute .
The target level in the BTS COPD guidelines indicates that an oxygen saturation level of 90% or above should be achieved and maintained with oxygen therapy. This level of saturation in the COPD guideline is consistent with the emergency oxygen one, which recommends that a range of 8892% as acceptable . In addition, the oxygen guidance highlights the importance of assessing each individual patient and analysing arterial blood gas measurements in conjunction with their clinical history.
The oxygen guideline also includes detailed information and working examples of oxygen prescription charts as well as examples of specific respiratory charts that incorporate patient observations such as respiratory rates with oxygen saturation values and oxygen therapy details.

How Does Oxygen Therapy Work During Asthma Attack
During an asthma attack, the muscle surrounding the bronchial tubes constrict. These tubes allow air to go in and out of a persons lungs. As the tubes narrow, the passage of air becomes extremely difficult making a person fall short of breath. Oxygen therapy supplies extra oxygen to the lungs when the levels are low.
Oxygen is delivered from a container to the person through a face mask or tubes into a persons nostrils.
How Does Oxygen Therapy Help Asthma Patients
The airways are the tubes responsible for carrying air into and out of the lungs, so keeping them fit, healthy, and in full working order is highly beneficial.
Asthma causes inflammation in the airways and the surrounding muscles to contract and tighten which makes it difficult to breathe. It can also result in wheezing and coughing.
Oxygenation or oxygen administration help in cutting back on the dangers associated with low blood oxygen levels in the first place.
This is majorly required and prescribed when a person suffers from life-threatening asthma or other complex respiratory troubles.
With oxygen therapy, however, the condition is treated and managed greatly as the lungs become flooded with essential oxygen, which greatly reduces the negative side-effects brought on by deadly asthma.

Using Home Oxygen Therapy
The main ways of using home oxygen therapy are through:
- short tubes placed in your nostrils this is called a nasal cannula
- a mask over your nose and mouth
Some people may need a tube inserted into an opening made in the front of their neck or a tube placed in their mouth and down their windpipe.
There are 3 types of devices that can be used to give you oxygen:
- an oxygen concentrator

Patient History And Waveform Capnography Help Identify Asthma Attacks
Asthma attacks can mimic other respiratory conditions. Wheezing from the lower airways can be difficult to distinguish from sounds caused by upper airway inflammation. Anxiety can trigger an asthma attack, but it can also cause hyperventilation with no bronchospasm. The sound of air passing, sometimes referred to as cardiac wheezes, through fluid-filled alveoli from pulmonary edema, can be made worse if misdiagnosed and treated as an asthma attack.
Not all asthma attacks cause wheezing. Cough may be the only sign of an asthma attack, especially in exercise-induced and nocturnal attacks . Breath sounds may be diminished or absent in severe asthma attacks, which an ominous sign of decreased air movement through the lower airways.
Waveform capnography is a valuable tool to differentiate an asthma attack from other causes of respiratory distress. The waveform represents air movement throughout the respiratory cycle, and is normally rectangular shaped. Bronchoconstriction causes air to be released unevenly from the alveoli, which makes the capnography waveform appear rounded, similar to a shark fin .
The length of the waveform also represents the exhalation phase, which is prolonged during an asthma attack. The more severe the bronchoconstriction, the more pronounced the shark fin and length of the waveform. This can be seen even if the patient has diminished breath sounds and is not wheezing.

Personal Asthma Action Plan
As part of your initial assessment, you should be encouraged to draw up a personal asthma action plan with your GP or asthma nurse.
If you’ve been admitted to hospital because of an asthma attack, you should be offered an action plan before you go home.
The action plan should include information about your asthma medicines, and will help you recognise when your symptoms are getting worse and what steps to take. You should also be given information about what to do if you have an asthma attack.
Your personal asthma action plan should be reviewed with your GP or asthma nurse at least once a year, or more frequently if your symptoms are severe.
As part of your asthma plan, you may be given a peak flow meter. This will give you another way of monitoring your asthma, rather than relying only on symptoms, so you can recognise deterioration earlier and take appropriate steps.

Measuring Your Oxygen Level
If your doctor suspects your oxygen level is low, he may do some diagnostic testing to determine the extent of the problem. This can include an arterial blood gas test, which uses a needle to draw blood through an artery to measure the oxygen level it contains, and a pulse oximetry test, which uses a special light to check the oxygen level.
Improves Recovery From Copd Exacerbations
COPD exacerbations happen when COPD symptoms flare up and stay worse for days at a time. They usually happen when you get an illness or infection that triggers inflammation in the lungs.
Exacerbations are a major threat to people with COPD, and preventing them is one of the major goals of COPD treatment. In severe cases, exacerbations can lead to life-threatening hypoxemia and require hospitalization to keep under control.
Fortunately, supplemental oxygen therapy has been found to reduce the risk of exacerbation in people with COPD. Studies also show that using supplemental oxygen temporarily during an exacerbation can boost your ability to recover, even if you don’t use it regularly at home.
Oxygen therapy can also reduce the length of hospital stays and reduce your risk for more serious exacerbation complications. This is a major benefit, since prolonged exacerbations are more likely to cause irreparable lung damage and worsened baseline COPD symptoms.

When To See A Doctor
If you or a family member is experiencing a first onset of symptoms of asthma, see your doctor. They may then refer you to a specialist. You should also see your doctor when you are experiencing less serious symptoms, and the tools you have to improve the asthma are not working.
When you seek medical attention for asthma your doctor can classify the severity of your asthma and select the best treatment. Because the degree of your asthma may change over time, its important to see a doctor regularly to adjust your treatment accordingly.
If you think you or a family member is experiencing an asthma attack, call 911 or local emergency services, or go to your nearest emergency room.
Diagnosing Asthma In Older People
Older people are more likely to have other lung diseases that also cause shortness of breath , so doctors have to determine how much of the persons breathing difficulty is related to asthma and reversible with the appropriate anti-asthma therapy. Often, in these people diagnosis involves a brief trial of drugs that are used to treat asthma to see whether the persons condition improves.

Why Doesn’t Asthma Usually Lower Oxygen Levels
Air enters your mouth and nose. It then travels down your pharynx and larynx to your bronchial airways. From there, it travels to the alveoli. Alveoli are where gas exchange occurs. It is here where oxygen from the air enters your blood system, and it is here where a waste product called carbon dioxide leaves your blood and enters your lungs.1,2
With each breath, you inhale O2 and exhale CO2. Through the process of normal breathing, your body maintains normal O2 and CO2 levels inside your blood. So, with good asthma control, it makes sense that your blood O2 and CO2 levels should remain normal.
Even during most asthma attacks, O2 and CO2 levels remain normal or at least in the normal range. Three theories explain this:
Lets discuss each of these individually.
How Does It Work
Oxygen treatments can improve your organ function, specifically your lungs, and improve symptoms that arise from certain conditions . When your blood oxygen content is low, it may cause you to feel fatigued, weak, confused, and short of breath.
After receiving an oxygen treatment, you may feel like you have more energy to participate in daily activities that previously caused you to feel fatigued . You may also feel like you are able to exercise for longer, and sleep better!2

The Benefits Of Using Supplemental Oxygen
We’ve briefly explained already how supplemental oxygen helps you breathe better and helps your lungs absorb more oxygen. We’ve also mentioned how this can prevent hypoxemia, a condition that occurs when there’s not enough enough oxygen in your blood to meet your body’s oxygen needs.
What we haven’t discussed yet is what effect this can have on the respiratory symptoms you experience every day. Fortunately, studies show that supplemental oxygen can actually help you feel better in general and improve your quality of life.
For example, many studies have shown that that oxygen therapy can improve shortness of breath in people with COPD, especially when used during physical activity. In fact, according to the American Thoracic Society and other researchers, oxygen therapy may be even more effective than bronchodilator medications at reducing shortness of breath caused by COPD.
Other studies have shown that supplemental oxygen can effectively reduce psychological ailments like anxiety and depression, as well as improve health-related quality of life in people with COPD. It can also reduce your chances of experiencing a COPD exacerbation, and help you recover if you do.
You might also find that you have more energy to be active and do everyday tasks when you use supplemental oxygen. Having low blood oxygen makes you feel drowsy and foggy, but these symptoms should at least partially recede when you use oxygen therapy to restore healthier blood oxygen levels.
