Understanding Blood Oxygen Levels

/0 Comments/in , , , /by

What is Blood Oxygen Level?

Blood oxygen level is the amount of oxygen circulating in the blood. Red blood cells carry most of the oxygen, collecting it from the lungs and delivering it to all parts of the body. A person’s blood oxygen level is an indicator of how well the body distributes oxygen from the lungs to the cells, and it can be important for people’s health.

Ways in measuring your blood oxygen level

There are two ways in measuring your blood oxygen level, arterial blood gas and a pulse oximeter. An arterial blood gas test is a blood test. It measures your blood’s oxygen level. The test also checks the balance of acids and bases, known as the pH balance, in your blood. An ABG is very accurate, but it’s invasive while the pulse oximeter is a noninvasive device that estimates the amount of oxygen in your blood. It does so by sending infrared light into capillaries in your finger, toe, or earlobe. Then it measures how much light is reflected off the gases. A reading indicates what percentage of your blood is saturated, known as the SpO2 level. This test has a 2 percent error window. That means the reading may be as much as 2 percent higher or lower than your actual blood oxygen level. This test may be slightly less accurate, but it’s very easy for doctors to perform. So doctors rely on it for fast readings.

How blood becomes oxygenated

Understanding how blood is saturated with oxygen begins with the alveoli or air sacs. There are millions of these microscopic air sacs in the lungs. They serve an important function to exchange oxygen and carbon dioxide molecules to and from the bloodstream. When oxygen molecules pass through the alveoli, they bind to hemoglobin which is a substance in the blood. As the hemoglobin circulates, oxygen essentially hitches a ride and gets dropped off to the body’s tissues. With this, hemoglobin picks up carbon dioxide from the tissues and transports it back to the alveoli so the cycle can begin all over again. The level of oxygen in your blood depends on several key factors, how much oxygen you breathe in, how well the alveoli swap carbon dioxide for oxygen, how much hemoglobin is concentrated in red blood cells, and how well hemoglobin attracts oxygen. Most of the time, hemoglobin contains enough oxygen to meet the body’s needs. But some diseases reduce their ability to bind to oxygen.

Measuring your blood oxygen levels

Generally speaking, an oxygen saturation level below 95% is considered abnormal and anything below 90% is an emergency. When this happens, oxygen therapy is needed, sometimes urgently. The brain is the most susceptible organ to hypoxia, and brain cells can begin to die within five minutes of oxygen deprivation. Should hypoxia last longer, coma, seizures, and brain death can occur. It is very important to determine the cause of low oxygen saturation in order to correct the problem. With chronic conditions, such as COPD and asthma, the root cause is usually low air exchange in the lungs and alveoli. In addition to oxygen therapy, steroids or bronchodilators may be needed to open the airways. 

Treatment

The treatment options for low blood oxygen levels include supplemental oxygen. Doctors can administer oxygen therapy in an office, or they can prescribe or recommend the use of home oxygen therapy. A range of devices is available for delivering and monitoring home oxygen therapy, but some require a prescription. People can make lifestyle adjustments to reduce the symptoms of low oxygen levels, as well as improve their general health and quality of life. Eating a healthy and balanced diet can also help improve blood oxygen saturation. Since iron deficiency is one of the major causes of low oxygen saturation, eating foods that are rich in iron, such as meat, fish, kidney beans, lentils, and cashew nuts, can be helpful.

5 Reasons to Buy from Us

/2 Comments/in /by

One- Is product health Canada approved?

This is by far the most important factor and concern many customers have. Health Canada has been working in the best interest of the public to set one of the world’s most comprehensive and diligent processes for importing and marketing medical devices.  Any company which imports and distribute products in Canada would need to have a valid Medical Device license meaning that the product has been tested and inspected by Health Canada to make sure is within the set guidelines. Unfortunately, Health Canada cannot have much control over companies who are based out of Canada, and also consumers who buy a product for personal use will not be addressed by the Health Canada device license requirement.  Potentially a customer could be buying a product which is made of inferior materials with low accuracy and health hazard from vendors which are based out of Canada even though the sold advertises shipping to Canada. One of the ways to spot this issue is the fact that many online vendors mention Sports use or leisure use or aviation use on the product which means the product is not a medical-grade product and is not reliable. All the product range listed on this website have valid medical device license issued by Health Canada.

Two – Where is the product shipped from?

We sent all our products from Canada. We have been using Canada Post as our main shipping partner since we can office our products to every single postal code in the country.

When you buy products that are shipped from outside Canada, you will not have any control over the shipping time as national holidays, customs clearance and many other factors can delay deliveries even up to a month.

Three- Is the price in the Canadian dollar and all other charges are included?

All our products are in Canadian Dollars. And the product customs and import duty had already been paid before we imported the product to Canada.  Our customers only pay the price which is listed and they are not liable to any import duty.

When you buy products from overseas and non-Canadian vendors, firstly you might go through the currency conversion which is not much in your favor most of the time as there is also the credit card company issues margin involved.  Moreover, when the product comes to Canada- CBS (Canadian border services) will inspect the package and depending on the value declared would add a percentage of custom duty on that and the receiver is liable for paying for that before the product gets released.

Four- What if I would need to return the product if the package is unopened?

We do understand that from time-to-time people’s decisions or needs change. Returning the product to us is pretty simple. You send the product back with your preferred shipping method. You will be liable for a full refund after a 15% re-stocking fee. (This is a fee covering the initial shipping cost that we send you the product)

When you purchase a product from overseas, we would certainly say “changing mind is not an option”. Your return shipping charges could be easily multiple times what you paid for the product.

Five- What warranty do I have for the products?

We have confidence in our product offering. Within the one year after the purchase for any reason if there has been an issue with the product you simply contact us via customer-serivce@123checkup.com. We will send you a pre-paid shipping label- you simply drop the faulty unit at the nearest Canada Post. Upon receiving the product, we will be sending you a brand new unit.

In contrast, many overseas sellers offer a warranty knowing the fact that it will never be economically viable for the customer to claim the warranty in case the product fails. Simply the shipping charge for sending the product will be very high. Most vendors would need 2-3 weeks to repair the unit and send you back with another 3-4 weeks transit time

We always trust our customers’ gut feelings and concerns. We are happy to answer any questions you might have.

What is Oxygen Saturation Monitoring in Children?

/0 Comments/in , /by

As parents, making sure that your child is healthy and happy is always a topmost priority. We are always in the lookout for any signs that can compromise their health. We want to monitor as much as we can on everything that happens to them.

One of the signs that we should be on guard for is Cyanosis or Turning Blue. This happens when there is not sufficient level of oxygen in the blood. It can be evident at birth but can also appear any time later in life and most often accompanies conditions in which the lungs or heart is compromised.

Cyanosis is one of the symptoms of Hypoxemia, a medical condition wherein there is an abnormally low level of oxygen in the blood. More specifically, it is oxygen deficiency in the arterial blood.

Oxygen saturation means the amount of oxygen being carried in your child’s red blood cells. The optimal oxygen saturation of the blood lies between 95-98 %. Anything less than 95% results in hypoxemia and should be a major concern.

How is oxygen saturation monitoring in children done? One way to measure oxygen saturation is through a test called arterial blood gas. Instead of taking the blood from the vein, it is taken from the artery and the amount of oxygen present is determined.

Another way is through a pulse oximeter. A pulse oximeter like CMS-50QB ‏is one device that can be used to monitor oxygen saturation. It is a simple, portable monitor for measuring oxygen saturation and pulse rate and is suitable for use indoors and outdoors. It is also used in monitoring COPD patients or those who suffer chronic obstructive pulmonary disease.

On one side, the clip contains a strong light source, which shines through the finger. On the other side, a sensor measures what proportion of the light penetrated through the finger and what was absorbed. Different proportions of light penetrate the finger according to the level of saturation of the blood. From this, the oxygen saturation figure is calculated. The pulse rate can also be measured and displayed. The sensor or probe is connected to the monitor by a long thin, wire. It can be used on the finger or the toe.

The monitor and sensor or probe is totally safe, non-invasive and will not hurt your child when it is applied securely but not tightly on the finger or toe. The probe or sensor may be used on a different toe or finger every 8 hours to make sure that the device is working and to give the child’s finger or toe some rest.

Children with low level of oxygen saturation need to be connected to the monitor at all times so that their level of oxygen is constantly monitored. While for others, monitoring can be done when they are sleeping. Your doctor or health provider will determine how long your child needs to be monitored.

When your child’s oxygen is low, oxygen therapy is done so that your child will receive a higher concentration of oxygen than we normally breathe in the air. A face mask or nasal tube is connected to a mechanical ventilator.
