8 factors to consider before buying oxygen concentrators

Oxygen concentrators are healthcare devices that assist those with respiratory insufficiency (hypoxemia). They are designed to concentrate oxygen in the air by removing nitrogen, helping those who require oxygen therapy to improve and stabilize blood oxygen saturation levels. While these devices are designed to help maintain oxygen levels, not all models work in the same way. So, it is important to consider all options and assess specific needs to choose the right device.

Oxygen concentration
While oxygen is compressed and filtered in the concentrator, the amount then delivered contains a specific percentage of pure oxygen. This value is known as the oxygen concentration. Before buying the device, one must check if the oxygen flow rate is about 2 L/min. This rate is usually sufficient for home oxygen concentrators. Some may require a higher flow rate, in which case they can choose devices with up to 10 L/min.

Noise levels
An oxygen concentrator generally produces some noise, which can be bothersome for many. So, when looking for a device, choose a model with noise levels between 31 dB and 60 dB. This range is equivalent to the sound of a quiet conversation or a voice in a calm environment. Additionally, some manufacturers offer models with quieter operation.

Portability
Having a portable oxygen concentrator can be beneficial for those who travel extensively. When choosing one, it’s important to take into account its size and weight. Some units are heavier and larger, offering higher flow rates. Those who do not require high oxygen flow rates must look for options between 5 and 10 pounds that come with lower flow rates. These lighter units are easy to carry and use on the move.

FAA (Federal Aviation Administration) approval
In addition to the portability of an oxygen concentrator, one should also look for an FAA-approved device. The certification makes the device one of the safest and most reliable options, even allowing one to carry the portable device on an airplane if required.

Essential features
Each oxygen concentrator has a standard set of features, but some models include supplemental features or accessories that enhance the user experience. These features may include carrying containers for portability, easy-to-replace filter systems for maintenance, flow-locking settings for controlled oxygen delivery, and various accessories for improved functionality. Since the feature set will differ from one product to another, one must review all available options before choosing a device.

Spare parts
The assistive device operates with the help of mechanical parts that require regular maintenance. One may need to repair or replace parts that malfunction or become damaged. So, while buying, one must ensure that the spare parts are available for at least one year, especially in case of power failures. Other essential spare parts to have on hand include the intake and internal filters.

Power supply
A non-portable oxygen concentrator is connected to an electrical network for continuous use. This type of device generally has low energy requirements. Other models operate on battery power, but these would require frequent recharging or battery replacements.

Alarm system
Before buying an oxygen concentrator, one must check if it has standard features like an alarm system. This function is crucial as it is activated when there is low oxygen concentration, no flow, high or low pressure, power supply failure, high temperature, or low battery. Additionally, one must be vigilant of devices with prolonged warm-up periods and auto-shutoff functions.

Simple lifestyle changes that reduce the risk of heart diseases

The heart is the most crucial organ in the body and as the system will cease to function if the heart stops or loses momentum pumping fresh oxygenated blood. This is why it is vital to not neglect your heart health at all and responsibly maintain a healthy, stress-free, and more importantly, a happy lifestyle. Here are a few simple lifestyle changes that will help support a healthy heart function. Switch to a healthy diet Avoid eating foods that are rich in trans and saturated fats. Most foods you find on the shelves of the supermarket contain large quantities of one or the other. Instead, switch to low-fat high fiber alternatives to help manage cholesterol. Maintaining a healthy cholesterol level in the body automatically reduces the risk of heart diseases. The simple reason for this is that fats that normally block major arteries and blood vessels are eliminated from these foods choices. It is also advisable to limit the salt (sodium) intake to control blood pressure and sugar to reduce the risk of diabetes simultaneously. Change certain lifestyle habits Reduce the number of alcoholic or carbonated drinks you have regularly. For men, it is advisable to have not more than two drinks and day and women must have only one.

How to distinguish between heartburn and GERD

Heartburn is an unpleasant, burning sensation in the chest that is more common than a lot of individuals realize. Pregnant women, older men, and even young adults experience it frequently. Despite it being such a prevalent experience, not many know that heartburn has actually nothing to do with the heart and everything to do with the stomach and the esophagus. Unsurprisingly enough, heartburn is also used interchangeably with GERD. But, before we get to deciphering heartburn and GERD, let’s understand what acid reflux is. What is acid reflux or GER? Acid reflux occurs when the lower esophageal sphincter or LES becomes weak, allowing the contents of the stomach to travel in the wrong direction, back up the esophagus. Acid reflux is also called GER or gastroesophageal reflux as it involves the stomach and esophagus. This condition can usually be resolved with over-the-counter medication. What is heartburn? Heartburn is a burning or painful sensation that is experienced in the chest. Since the lining of the esophagus is not as strong as the lining of the stomach, the acid from the stomach can cause a burning sensation in the chest. This pain or burning sensation that is heartburn can often be misconstrued for a heart attack.

5 common joint conditions and how to treat them

A joint or articulation is made from two bones that aid the body in movement. There are many forms of joint conditions, which, in many cases, arise from the wear and tear of bones. Arthritis is one of the major and most common health conditions in the country, and its intensity increases with age. Here are some common types of joint conditions that you need to know: Osteoarthritis With almost 10 percent of men and 13 percent of women aged over 60 suffering from osteoarthritis, it is one of the most prevalent joint conditions in the country. Osteoarthritis occurs due to the wear and tear of the cartilages that protect the ends of bones. It commonly affects joints of the spine, hands, hips, and knees. If left untreated, this wear and tear of the cartilage soon leads to bone degeneration, thereby affecting flexibility and range of movement. Treatment for osteoarthritis depends on its severity and the patient’s age. Mild symptoms can be treated through medications, physiotherapy, and changes in lifestyle, whereas moderate to severe cases may require surgical intervention. Spondyloarthritis Spondyloarthritis, also referred to as spondyloarthropathy, is a type of rheumatic disease that causes inflammation in various joints. There are two types of spondyloarthritis—axial spondyloarthritis, which causes inflammation of the joints in the chest, spine, and hip bone, and peripheral spondyloarthritis, which causes inflammation in the fingers, knees, and toes.
