Reading time:&#xA0;4 minutes, 29 seconds&#xA0;Oxygen therapy is a prescription treatment that delivers supplemental oxygen to a patient, usually via nasal prongs (an oxygen cannula) or a face mask. Oxygen equipment can be attached to other medical devices such as ventilators and CPAP machines. While common in hospital settings, oxygen therapy can also be used at home. A range of options is available to those who require at-home oxygen therapy, from portable machines to larger standalone units.&#xA0;A number of health conditions may necessitate the use of oxygen therapy, either short-term or over an extended period of time.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="obstructive-sleep-apnea-osa">Obstructive sleep apnea (OSA)</h3>Obstructive sleep apnea (OSA) occurs when a blockage in your airway stops or interrupts your breathing while you&#x2019;re asleep. The resulting lack of oxygen wakes you up for just long enough to begin breathing again, which <a href="https://www.canada.ca/en/public-health/services/chronic-diseases/sleep-apnea.html" rel="noopener noreferrer" target="_blank">interrupts sleep and puts stress on the heart</a>. Those with OSA may experience excessive daytime sleepiness, loud snoring, stopped or interrupted breathing, abrupt awakenings, morning headaches, and depression or irritability.&#xA0;Low blood oxygen levels are an instant consequence of obstructive sleep apnea. Oxygen therapy has been used as an alternative treatment for OSA patients who don&#x2019;t adhere to continuous positive airway pressure (CPAP) in order to reduce the harm caused by low blood oxygen levels during sleep. Research has proven oxygen therapy to <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3578679/" rel="noopener noreferrer" target="_blank">significantly improve oxygen saturation in OSA patients</a>.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="chronic-obstructive-pulmonary-disease-copd">Chronic obstructive pulmonary disease (COPD)</h3>Chronic obstructive pulmonary disease (COPD) is a group of diseases that cause airflow blockage and problems with breathing. Over two million Canadians aged 35 and above <a href="https://health-infobase.canada.ca/datalab/copd-blog.html" rel="noopener noreferrer" target="_blank">were living with diagnosed COPD in 2013</a>, and many more are thought to be dealing with the disease undiagnosed.&#xA0;Long-term exposure to irritants like tobacco smoke is the principal cause of COPD. The condition is progressive and primarily affects those over the age of 35. COPD&#x2019;s main symptoms include increasing breathlessness, a persistent chesty cough with phlegm, wheezing, and frequent chest infections. Less commonly, weight loss, tiredness, and swollen ankles can occur as a result of COPD: these symptoms typically only happen in the advanced stages of the disease.&#xA0;COPD currently has no cure, but its symptoms can be managed through various medications, lifestyle changes, and other treatment courses &#x2014; including oxygen therapy. Oxygen therapy raises the amount of oxygen that enters the lungs and bloodstream. For those with low blood oxygen levels due to COPD, supplemental oxygen can <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2645328/" rel="noopener noreferrer" target="_blank">alleviate breathing problems and improve exercise capacity</a>. Long-term oxygen therapy has also been proven to increase survival in COPD patients with severely low blood oxygen levels.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="pneumonia">Pneumonia</h3>Pneumonia is the inflammation of lung tissue. It is usually caused by a virus or bacterial infection and can affect one or both of the lungs. Symptoms of pneumonia can arise over the course of 24 to 48 hours, or may develop more slowly over a number of days. Common symptoms of pneumonia include a cough (which may be dry and produce phlegm), difficulty breathing, rapid heartbeat, high temperature, sweating and shivering, loss of appetite, and chest pain that worsens when coughing or breathing.&#xA0;Oxygen therapy may be used to treat patients with pneumonia who have low blood oxygen levels. A 2012 study examining the efficacy of oxygen therapy as a treatment for pneumonia patients found non-invasive ventilation <a href="https://pubmed.ncbi.nlm.nih.gov/22419316/" rel="noopener noreferrer" target="_blank">can reduce the risk of death in the intensive care unit</a> and shorten the length of a patient&#x2019;s ICU stay.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="pulmonary-fibrosis">Pulmonary fibrosis</h3>Pulmonary fibrosis is a condition that occurs when lung tissue becomes scarred and damaged. The compromised lung tissue is thicker and stiffer, which makes it harder for the lungs to function properly. Pulmonary fibrosis patients become increasingly short of breath as the disease progresses. Symptoms include short, shallow breathing, a persistent dry cough, fatigue, and unexplained or unintended weight loss.&#xA0;Individuals with pulmonary fibrosis may be prescribed oxygen therapy to help with breathing problems. According to the <a href="https://cpff.ca/understanding-pf/treatment-and-care/oxygen-therapy/" rel="noopener noreferrer" target="_blank">Canadian Pulmonary Fibrosis Foundation</a>, oxygen therapy can reduce breathlessness and fatigue in those living with the condition. Oxygen therapy can also help individuals with pulmonary fibrosis maintain proper blood oxygen levels, which is essential for the function of the muscles, organs, and brain.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="cystic-fibrosis">Cystic fibrosis</h3>Cystic fibrosis is an inherited disease that causes viscous mucus to accumulate in the organs, including the lungs. This thick mucus can impede the airways and make it difficult to breathe. Cystic fibrosis also affects the pancreas, liver, sinuses, and intestines. Symptoms of classic cystic fibrosis include an inability to gain weight despite having a healthy diet, loose or oily stools, breathing problems, recurring lung or sinus infections, and wheezing.&#xA0;Oxygen therapy can be used to alleviate some of the respiratory symptoms associated with cystic fibrosis, and research has shown this treatment to help patients exercise for longer. One study found that six and twelve months into treatment, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6464979/" rel="noopener noreferrer" target="_blank">there was an improvement in regular attendance at school or work</a> in cystic fibrosis patients receiving oxygen therapy.<h3 style="margin-top:16.0pt;margin-right:0cm;margin-bottom:4.0pt;margin-left:0cm;text-align:justify;line-height:150%;font-size:19px;font-family:&quot;Proxima Nova&quot;;color:#434343;font-weight:normal;" id="a-severe-asthma-attack">A severe asthma attack</h3>Mild and moderate asthma attacks are generally addressed with air driven nebulizers or metered dose inhalers and holding chambers. In the case of a severe or life-threatening asthma attack, oxygen therapy may be used to deliver additional air to the lungs and replenish oxygen in the blood.&#xA0;There are many reasons a person might need oxygen therapy, and the treatment can be incredibly beneficial in easing the symptoms of a number of health conditions. It&#x2019;s important to note that oxygen therapy can only be accessed by prescription. If you are experiencing symptoms that indicate low blood oxygen levels, consult your doctor for guidance.

Read Time:&#xA0;1 minute, 26 secondsOximetry is a non-invasive test used to measure the oxygen saturation levels in the blood, providing valuable insights into how well oxygen is being circulated throughout the body. This quick and painless method primarily focuses on analyzing the body parts farthest from the heart, offering crucial information about one&apos;s overall health.At the heart of oximetry lies the pulse oximeter, a sensor device commonly placed on the fingertip. It utilizes two wavelengths of light that are passed through the finger, reaching a photodetector or photosensor. By measuring changes in absorbance, the device can accurately determine the amount of oxygen present in pulsing arterial blood.The main purpose of an oximeter is to assess the efficiency of the heart in pumping oxygen-rich blood to all parts of the body. It is particularly useful for individuals who may have a medical condition that affects blood oxygen levels, especially within hospital settings where close monitoring is essential.Despite their small and straightforward design, oximeters play a crucial role in providing vital information about one&apos;s health. They can be used in conjunction with oxygen concentrators to ensure optimal oxygen levels are being reached within the body. It is important to note that normal blood oxygen levels typically range from 80 to 100 millimeters of mercury. However, it is always recommended to consult a medical professional to interpret your results accurately and determine the appropriate measures to manage blood oxygen levels effectively.Oximeters offer a convenient and reliable means of monitoring blood oxygen saturation levels, allowing individuals to proactively manage their health. By regularly using this valuable tool, individuals can ensure that their body is receiving adequate oxygen supply, enabling them to make informed decisions about their well-being.
