I am pleased to support any new research and products to treat nasal obstruction and aid breathing, as chronic nasal obstruction is a common problem that can have a great impact on quality of life and quality of sleep. I have been impressed with the efforts of Breathing Solutions UK Ltd to develop the Nose Vole and Nasal Actuator as breathing aids for those with nasal obstruction, as this type of product is suitable for long-term daily use, unlike the decongestant nasal sprays that can only be used for a period of 7-10 days. The inventor of the Nose Vole and Nasal Actuator, Keith Stewart, has found his own solution to his nasal obstruction by developing the products over many years, and this story is similar to the invention of Breathe Right Nasal Strips that were invented by a non-specialist who wanted to treat his own nasal obstruction. Great inventions can and do arise from the creativity and dedication of non-specialists and I am pleased to wish the new company, Breathing Solutions UK Ltd every success with their venture.

Sleep deprivation due to poor nasal breathing Have you ever noticed that when you lie down to go to sleep with a blocked nose that it can become even more difficult to breathe? As described earlier, when we go to sleep the muscles in the airways become more relaxed. This, combined with the increased airflow resistance due to lying down to sleep, reduces the diameter of these passages. This results in restriction of the flow of air to the lungs, which may already be compromised due to various possible factors. See more in our Nasal Breathing Impairment article Studies have shown that nasal obstruction can significantly increase the frequency of disturbed sleep. An ongoing impediment to sleep patterns may result in what is known clinically as hypopnea (from the Greek hypo meaning ‘low’ and pnoe meaning ‘breathing’). In hypopnea, an excessive reduction of airflow can lead to continual arousals or waking from sleep. The natural phenomenon of the nasal cycle, where nasal patency switches from one side to another can also contribute to waking at night. It may be a one-sided mechanical nasal blockage, or simply a habit of sleeping on one side that may trigger night time arousal or waking when there is a switch in nasal cycle. In order to improve their sleep, people with restricted nasal breathing may have to modify their sleeping position to allow...Read More
Causes of impairment of nasal breathing For both people with or without an existing respiratory disorder, a greater pressure on the upper respiratory system airways when you lie down horizontally creates a restriction in the flow of air to the lungs. Scientific studies have shown that the recumbent position you would be in to get off to sleep relates to an increase in airflow resistance. This causes a marked decline in the volume of air that enters the lungs. In addition to this, the relaxation of oral and pharyngeal tissue during sleep puts a greater demand on the nasal air passages as the main supply of oxygen to the lungs while sleeping, so it is important to ensure an optimal airflow through the nose to ensure a good night’s sleep. The combination of this phenomenon and other factors of nasal obstruction can greatly affect our quality of sleep. There are various additional aggravating factors that may impair nasal breathing. Examples of factors which decrease airflow and ease of breathing include: Pharyngeal narrowing, due to recumbency (lying in a comfortable position to sleep) and sleep induced (relaxation causing narrowing of air passages) Structural nasal diseases, such as nasal polyps, collapsed valve, deviated septum, hereditary, accidental, or surgical malformations Swelling and secretions of nasal mucosal tissue, due to inflammatory causes, such as allergies, sensitivities, rhintitis, sinusitus, viral infections – colds, flu,...Read More
Rhinomanometry is a technique used to quantify the degree of nasal obstruction and an Anterior Rhinomanometer allows the obstruction on each side of the nose to be measured separately. The instrument measures the pressure at the back of the nose and the air flow this pressure produces, during both inspiration and expiration, and separately for each side of the nose. While the resistance values are calculated and presented numerically, they can also be shown graphically in the form shown. Flow is shown on the vertical axis and pressure on the horizontal and by plotting a flow/pressure graph, the slope of the trace gives a good visual indication of obstruction. The closer the trace is to the horizontal axis the more obstruction is present, so a trace which is almost vertical indicates a very clear, or open nose. The more open the nose, the less obstruction is present, and the easier it is to breathe. The graph shows the result achieved by a subject, who had a measurement made before and after fitting a Breathing Solutions Nasal Actuator unit. The reduction in resistance was calculated to be 78% during inspiration and 79% during expiration — a very significant improvement.

What is your Nasal Cycle? We all need a good supply of air to make sure we are getting enough oxygen into our bloodstream. Although it is possible to breathe through your mouth when your nose is blocked, most experts agree that this is not ideal. Breathing through your mouth means that the air you are taking in has not passed over the natural filtering system inside your nose. You also wake with a dry, uncomfortable mouth and throat. At any one time, one of our nostrils is letting in the majority of the air that is reaching our lungs. The other one is busy producing mucus. This process switches sides after a few hours – the time varies from person to person – and is called the nasal cycle. No-one is certain why this nasal cycle exists. Some experts believe it is part of the nose’s self-cleaning mechanism, to help our bodies defend against infection. Other experts believe it has to do with our sense of smell – a lower volume of air, through a moist nasal passage, helps us to detect different scents. If you are fit and well, and do not have any nasal problems, you probably won’t notice this cycle. However, if you get a cold, the flu or a bout of hay fever, you will. The nasal cycle is the reason that one nostril...Read More
