Breathing Techniques Explained

First of all, what is 'Breathing'? This is the means evolved by nature for animals to facilitate the exchange between blood and air primarily of Oxygen and Carbon Dioxide. The lung developed in early animals to do this job in a protected part of the body. The membranes and blood vessels associated with the gas exchange are delicate. Another major function of breathing is controlling how acid (PH level) our bodies are.

In a fit healthy person the lungs have the ability to service the body in extreme activity, while in very challenging environments, such high altitude, bad weather, and bad air conditions caused by chemical fumes, smoke or poor ventilation. At rest, this fit healthy person breathes very slowly, and shallowly. This is as much as they need to do to maintain the body. They are probably using between five and ten per cent of their lung capacity.

When a person's lungs start to get damaged, whether through smoking, environmental conditions, or illness, the reduction in capacity does not really get noticed until about fifty per cent of that capacity has been lost. As we continue to lose capacity, the importance of breathing correctly so as to make the most of what we have becomes more and more important.

When we consider how we breathe, think about posture. If we are sat, sagging forward with a curled spine, then we are restricting our lungs ourselves, the bottom part of both lungs being unable to expand, and our diaphragm cannot operate properly. When we hold our bodies straight,whether sat or stood, with an erect spine, then the lungs and diaphragm have room to function.

The next thing to consider is that if we are not breathing, and are relaxed in an upright attitude, then the neutral position of our lungs is that they are between half and three quarters full. Then it stands to reason that the easiest first movement is to breathe out. So when in difficulty with breathing as we get with COPD, we need initially to concentrate on breathing out, to make room for a useful inward breath.

Now let us consider how we breathe in. When all is well, we are relaxed, not demanding much oxygen, then we tend to breathe gently in and out through the mouth. This just uses the very top part of the lungs, using chest expansion by the ribs and associated muscles. This is not very efficient, but for most people at rest, it doesn’t need to be. Next, let us think about breathing gently in through the nose and out through the mouth. This brings more of the lungs into play, and is starting to get the diaphragm working. Better than mouth breathing, but when those of us with severe COPD get into trouble, it is not enough to get sufficient oxygen into the blood stream, and carbon dioxide out. To do that we need to breathe out through pursed lips. Think of trying to whistle. Then shut the mouth and breathe in through the nose. Then out again through pursed lips. Sit up straight. Shut the mouth. Breathe in through the nose. Practice this when we feel good. You can feel the diaphragm working. Breathe long, and deep and slow. Those of us with a pulse oximeter, if we put it on before practicing deep breathing, will see that our resting O2 level is probably low to mid nineties. Now start deep breathing, it will take about a dozen or maybe as many as twenty breaths to get full use of the lungs. Watch the meter, over a period of a few minutes, you should see an increase of three or four per cent. Keep it up for ten minutes or so, and we feel good, but this is taking effort. It is difficult to sustain for long periods, and concentration will start to lapse. So doing it all the time is not what we need, neither is it natural. But for those of us with limited lung capacity, it is a good idea to practice the technique when we are well so that when we get breathless and struggle, we have something to help get us back on an even keel. Most of the time, we have a wife, husband, partner or carer near us. If they know the technique, when our breathing goes wrong, they will have something to help us with, getting us sat, reminding us to breathe in through the nose, blow out through the mouth, watching us, telling us. When we panic, it is difficult to think right, and we tend naturally to gasp through the mouth, and we need reminding of the best way. Be tolerant of those telling us, they are trying to help us. If you are in the carer role, be tolerant of your patient, in a breathlessness event, they are going through a difficult time.

While we are doing our good breathing technique, what is going on inside our lungs? Probably not quite what you think. In the middle of a deep breathing practice session, each breath in takes about four seconds, and a breath out about the same or a second or two longer. The diaphragm is working properly. All is good. As we breathe in, there is some chest expansion and the diaphragm pulls downwards, making the lungs expand and lowering the pressure in them, causing air to enter from the atmosphere. This is important, the lowering of pressure, I mean. Because of the lower pressure, carbon dioxide is encouraged to leave the blood stream, pass through the membranes into the alveoli (the small sacs at the ends of the smallest airways where the gas exchange takes place). When we breathe out, the chest contracts, and the diaphragm pushes up to make the lungs empty. The pressure inside the lungs increases, especially if we use pursed lips to cause a constriction. This is how we blow balloons up. Inside our lungs, the increased pressure pushes oxygen through the membranes to be taken up by the blood stream. This is not how we normally associate our breathing with our lungs and blood stream exchanging oxygen and carbon dioxide. Usually we think of it as the other way around.

When we get a problem with breathing, it is usually because our technique falls apart, the diaphragm not working properly being the usual reason. How can we help ourselves avoid emergency situations due to breathing. Be self aware. When we first sense that something is going wrong. Stop. Sit. Try and relax. When you can, if need be, move to where there is fresh air. Use this deep breathing technique. Use your inhalers. If you don't regain control quickly, get someone to call an ambulance.

When ambulance staff or paramedics attend someone with breathing difficulties, their standard procedure is to first of all get oxygen going into the patient, then to get a nebuliser going.

The nebuliser will normally be loaded with salbutamol (Ventolin) and Atrovent (Ipratropium Bromide). Salbutamol works by acting on receptors in the lungs called beta 2 receptors. When salbutamol stimulates these receptors it causes the muscles in the airways to relax. This allows the airways to open.In conditions where there is narrowing of the airways, such as asthma or chronic obstructive pulmonary disease (COPD, eg emphysema and chronic bronchitis), it is difficult for air to get in and out of the lungs. By opening the airways, salbutamol makes it easier to breathe. Ipratropium works in the lungs, where it blocks other receptors called muscarinic receptors that are found on the muscle surrounding the airways. A natural chemical called acetylcholine normally acts on these receptors, causing the muscle in the airways to contract and the airways to narrow. Ipratropium blocks the muscarinic receptors in the lungs and therefore stops the action of acetylcholine on them. This allows the muscle around the airways to relax and the airways to open. This makes it easier for people with asthma or COPD to breathe. The combined action gives a rapid response that quickly leads to easier breathing. With the return to more normal breathing, relief soon brings a feeling of being back in control and you become calmer.

After you are stabilised, you will probably be taken to hospital for tests and observation. At the hospital if infection is found you will be given appropriate antibiotics, and a drug regime established or your current one reviewed. The most common result is you leave with a bag full of drugs including Ventolin, Spiriva, Uniphylin tablets, and others to deal with side effects. The important one with regard to the subject of this article is Spiriva. This is drug is closely similar to Atrovent being intended to help your body maintain good control of your breathing. The difference is that Spiriva is intended to be a one dose daily drug to give 24 hour cover, whereas Atrovent is quick acting but short lived in the body. If you have Spiriva prescribed, take it, once daily. Do not take Spiriva and Atrovent on the same day, except under medical supervision.

I hope this article help you as patients or maybe as carers to understand what goes on when we breathe, and to be able to help ourselves or our charges when it goes wrong.

Remember, breathe easy,

PS. I am not a medical professional. I am writing this to try and fill a gap in general knowledge about COPD. If I have written something wrong, say so. We all have something to learn, especially me.

PPS. The PS above was proven when a comment made me check The actions of Ventolin and Atrovent. I have now amended the article to give the correct information. Johnwr.

  • I was very impressed to receive this information. I have decided to print the information so that I can assimilate the content better on paper. I feel it will be of help to me.

    I am fortunate that the condition bronchiectasis has only manifested itself during the last 10 years, although I have been on puffers for the last 20 years. I have bronchiectasis and asthma. Not badly but my breathing has restricted my mobility to the point of needing a buggy and rollator. I walk with difficulty and suspect that |I should lose weight. Not easy.

  • Hello annie80

    Just hoping to help to help people learn about things to do with COPD.

    If I can help with questions,just ask.

  • Thanks very much, Johnwr

  • thanks found that very informative this is all new to me.

  • Excellent, enjoyed reading..x

  • Thank you very much.

  • I practised while reading this and although not in severe distress at the time I noticed that the posture and nose breathing, with pursed lips for the exhale, did calm me within a few minutes. Most important for me I feel as if I now have some control. Now going to search and see if there are any breatheasy meetings locally.

    Many thanks

  • Hello hajoed,

    Thank you for your comment. It gives a nice feeling to know I've done some good.

  • thanks for the important info. Just one point re Atrovent - I have that prescription for an emergency at home - as am allergic to salbutimol - I thought they did the same thing - your article says they are different ?

  • Hi juliekkay

    Thanks for your comment. Discussion is how we advance in our understanding.

    The first thought I had when I read your comment was, 'In that case, why would paramedics mix the two in a nebuliser?'

    Then I thought, 'Check', so I did. What did I find out.

    Both drugs, as you say, do the same thing. But they do it in different ways

    Ipratropium works in the lungs, where it blocks receptors called muscarinic receptors that are found on the muscle surrounding the airways. A natural chemical called acetylcholine normally acts on these receptors, causing the muscle in the airways to contract and the airways to narrow.

    Ipratropium blocks the muscarinic receptors in the lungs and therefore stops the action of acetylcholine on them. This allows the muscle around the airways to relax and the airways to open. This makes it easier for people with asthma or COPD to breathe.

    Salbutamol works by acting on receptors in the lungs called beta 2 receptors. When salbutamol stimulates these receptors it causes the muscles in the airways to relax. This allows the airways to open.

    In conditions where there is narrowing of the airways, such as asthma or chronic obstructive pulmonary disease (COPD, eg emphysema and chronic bronchitis), it is difficult for air to get in and out of the lungs. By opening the airways, salbutamol makes it easier to breathe.

    The result is a rapid relaxation of the airway, and we can breathe easier again. We become calmer, simply because we are breathing easier.

    Thank you again for making me look closer and research a bit harder. Often we take what professionals tell us for granted. That is what I did here and was proven wrong to do so. I will now see about amending the article!!!

    Score 1 for you!

  • Thankyou ..Really good advice ,

  • johnwr

    Thank you for posting this useful information.

    I used my Desktop PC upstairs on a proper office desk and chair but then got a laptop and started using it on the kitchen table/kitchen chair. No way the same support for the spine and I felt my lungs being squashed up as you described - certainly did not help my breathing!

  • Terrific bit of writing, johnwr, very helpful. I am now going to save it to my laptop to refer to as and when required! Thank you.

  • Wow, what a lot of interesting info! I recently went on a 'breathing course' which I found super-helpful, unfortunately there are not many of them due to the usual problem - money. I learned about pursed lips breathng there, but find it is something I do naturally when in difficulty. I also learneds that I should do more simple arm/leg exercises to built up my core muscle strength to help the whole breathing process, and that I should 'push' myself more than I have been willing to do. It has all helped, wish everyone could have the course. Ask the doc? I am 69 and have been 'asthmatic' since the age of 5, but recently been told it is COPD, and put on Spiriva. Have had a briliant summer but now winter is on its way I am hopng the training I had will help to minimise the usual problems.

  • PS - The course was a Pulmonary Rehabilitation course, please nag your doctors!

    I am new to this site - would a blog about the course be useful??

  • I think it would Sylvsmum, we could recount our experiences!

  • Hi Ciss, since writing the above I've discovered there is already a Pulmonary Rehabilitation 'tag' on here! Have added to that.

    Have you been on this course??

    A

  • I haven't seen tag yet but yes I went on PR course this year, so brilliant I wish I could do it again!

  • Me too, Ciss, but was told that budget cuts mean they might be phased out. Tragedy, they do so much good. Doubt if they would give us a second bite at the cherry though!! Just have to keep on remembering to do the exercises, push yourself, eat well, etc etc etc!

  • Thank you if just read this and have found it very,helpfull ,because my attacks only last half hour I have never called for medic help but do I think I should or only if it last longer ,as after I do find it hard for few days after I have these? Helen

  • Thank you Johnwr for your breathing technique info. and for taking the time to post it.

    I have copied it and will read it often. I pray it will help many others to breathe more easily when an attack occurs.

    Bless you and have a great Christmas

  • I have been using ventolin and atrovent inhalers for years and find it is the best combination for me ,at last I understand why .Thank you.

    Woody

  • Thankyou very good advice ...have a good day everyone x

  • Thank you very much for this information. Despite having had COPD for some years and being on oxygen 24/7 no-one had ever explained these techniques to me previously. I was using them as I read the article and the result was noticable immediately so I shall print the article so I may refer to it at my leisure. Again, a big thank you.
