COVID-19 Who's at higher risk

COVID-19: Who’s at higher risk

COVID19 and people who are at higher risk are from all walks of life, but some may have greater chances of catching it or are often more severe. Including those over age 60 and people with heart disease, lung disease, or diabetes. A lot depends on the kind of work you do, the conditions you live in, and whether you have other health problems.

Older Adults 

The risk of developing dangerous symptoms increases with age, with those who are age 85 and older at the highest risk of serious symptoms. An estimated 6% to 29% of people 85 and older who get COVID-19 will require intensive care. Here are some reasons why:

  • As you age, changes to your lung tissue can make it harder to heal from COVID-19.
  • Older adults are more likely to have long-term health problems that can put them at risk.
  • Your immune system weakens as you age, making it more difficult for older people to fight off infections.
  • Older adults are more likely to have long-term health problems that can put them at risk.

Conditions That May Raise Your Risk of serious complications with COVID-19

Heart problem: Although COVID-19 most often affects the airway and lungs, these organs work together with the heart to drive oxygen to the body’s tissues. When the lungs are overtaxed due to illness, the heart has to work harder, which creates challenges for people who are already living with heart disease. Raise your risk of severe illness.

Chronic airway and lung diseases: People with this long-term condition may already have lung damage that can set the stage for more severe infection with the new coronavirus because of scarring, inflammation, or lung damage. 

Diabetes and Obesity: Diabetes type 1 and type 2 both cause an increase in blood sugar. Poorly controlled blood sugar can cause viral diseases. In addition, diabetes increases inflammation and weakens the immune system, making it harder for people living with the condition to fight off disease in general. 

Weakened immune system: conditions and treatments that can weaken your immune system, including:

  • Organ transplants
  • Cancer treatments
  • Bone marrow transplant
  • HIV/AIDS
  • Long-term use of prednisone or similar drugs that weaken your immune system

Children are less likely to get COVID-19 than adults, and severe cases are rare.

Essential workers like doctors, nurses, nursing home workers, and home health aides are in the front lines of the fight against COVID-19. Grocery store employees, mail carriers, bus drivers, and others also have important jobs that can’t be done at home. The kind of work they do means they need to interact with others outside their homes, which puts them at higher risk of infection. 

Whether or not they are in a high-risk category, everyone needs to take steps to protect themselves by getting a vaccine that can prevent you from getting the COVID-19 virus or prevent you from becoming seriously ill if you get the COVID-19 virus. 

Experts recommend that you take these steps:

  • Wash your hands often.
  • Avoid large events and mass gatherings.
  • Avoid touching your eyes, nose and mouth.
  • Avoid sharing dishes, glasses, towels, bedding and other household items if you’re sick.
  • Stay home as much as you can.
  • If you have to go out, make sure you stay 6 feet away from others, or about two arm lengths.
  • Meet up with other people outdoors when possible.
  • Wear a face mask in indoor public spaces and outdoors where there is a high risk of COVID-19 transmission, whether you are fully vaccinated or unvaccinated. 
  • Avoid large events and mass gatherings.
  • Clean and disinfect frequently touched surfaces in your home every day to stop the spread of the virus from person to person.

What is The Normal Oxygen Level?

Blood oxygen level is the amount of oxygen circulating in the blood. Your blood oxygen level measures how much oxygen is circulating with your red blood cells. The body closely monitors blood oxygen levels to keep them within a specific range, so that there is enough oxygen for the needs of every cell in 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.

What should oxygen levels be?

Normal arterial oxygen pressure (PaO2) measured using the arterial blood gas (ABG) test is approximately 75 to 100 millimeters of mercury (75-100 mmHg). A blood oxygen level below 60 mm Hg is considered low and may require oxygen supplementation, depending on a doctor’s decision and the individual case.

Hypoxemia is diagnosed by physical examination and generally detected using ABG testing and is defined as blood oxygen levels above 120 mmHg.

When the level goes below 75 mmHg, the condition is generally termed hypoxemia. Levels under 60 mmHg are considered very low and indicate the need for supplemental oxygen. Supplemental oxygen is provided through an oxygen cylinder that is connected to the nose via a tube, with or without a mask.

Your blood oxygen level is measured as a percentage—95 to 100 percent is considered normal.

You should be check your blood oxygen if

  • Chronic obstructive pulmonary disease (COPD)
  • Pulmonary fibrosis
  • Pulmonary hypertension
  • Cystic fibrosis
  • Asthma
  • Congestive heart failure

Other conditions include:

  • Anemia
  • Sleep apnea (temporary cessation of breathing during sleep)
  • Smoking

How is the blood oxygen level measured?

The most efficient way to monitor blood oxygen levels is by an arterial blood gas or ABG test. For this test, a blood sample is taken from an artery, usually in the wrist. This procedure is very accurate, but it can be a little painful. Another fast and easy way is by the use of a pulse oximeter. It’s a small device that clips onto your fingertip. It shines a light into the tiny blood vessels in your finger and measures the oxygen from the light that’s reflected back.

When to see a doctor

  • severe and sudden shortness of breath
  • severe shortness of breath that get worse during exercise or physical activity
  • shortness of breath even when at rest
  • wake suddenly with shortness of breath or a feeling of choking

How To Measure Blood Oxygen Saturation?

What is SPO2 or Oxygen Saturation?

What is SPO2?

SpO2, also known as Blood Oxygen Saturation, an estimate of the amount of oxygen in the blood. Which refers to the amount of oxygenated hemoglobin in the blood. Hemoglobin is a protein in red blood cells that transports oxygen and carbon dioxide. It is found inside red blood cells and gives them their red color. 

Understanding SpO2 and Normal Oxygen Levels

A measurement of your blood oxygen is called your oxygen saturation level. Your blood oxygen level is a measure of how much oxygen your red blood cells are carrying. Your body closely regulates your blood oxygen level. It is vital to your health to maintain the precise balance of oxygen-saturated blood.

A SpO2 reading of 95% or greater is generally considered to be a normal oxygen level. However, a SpO2 reading of 92% or less (at sea level) suggests that your blood is poorly saturated. Insufficient saturation can cause a range of adverse health conditions including chest pain, shortness of breath, and increased heart rate.

Measuring SpO2

There are two ways that the blood can be tested to ensure it contains normal oxygen levels. 

  • An arterial blood gas (ABG) test is a blood test and it’s called  Arterial blood gas. It also can detect the level of other gases in your blood, as well as the pH (acid/base level). An ABG is very accurate, but it’s invasive.
  • The most common way is to use a pulse-oximeter to measure the SpO2 levels in the blood. Pulse oximeters are relatively easy to use, are very accurate despite their low price point.

A measurement of your blood oxygen is called your oxygen saturation level. Good blood oxygenation is necessary to supply the energy your muscles need in order to function, which increases during activity. If your blood oxygen level is below-normal it is called hypoxemia and that could be a sign of poor blood oxygenation, also called hypoxia. Your doctor can provide recommendations as to what ranges of oxygen levels are acceptable for you.

How asthmatic kids can benefit from the pulse oximeter

The pulse oximeter is a device that can tell how much oxygen is in the blood. Ideally, oxygen saturation should be between 95-99%. If it hits 95% or lower would result in hypoxemia and should be a major concern. The child should be rushed to the ER if it is anything below 90% because, without enough oxygen, the major organs in the body such as the brain, liver, etc. can be damaged just minutes after the symptoms start.

How can the pulse oximeter be beneficial for kids with asthma? When a child has a flare or a severe asthma attack, the airway narrows making it hard for the child to breathe and the air to get in the lungs. Coughing to clear the lungs uses more oxygen thus making the symptoms worse. Oxygen levels can also drop even when the child has stopped coughing or when sleeping. There are some people with breathing problems that have died in their sleep because they weren’t getting enough oxygen. So, by regularly using the pulse oximeter, the level of oxygen saturation can be measured determining whether the child is still getting enough oxygen or the oxygen saturation level is too low.

The pulse oximeter like the 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. Other people who benefit from regularly measuring the level of oxygen saturation are patients with heart problems and anemia among others.

What is Oxygen Saturation Monitoring in Children?

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.
