Diagnostic Tests And Procedures
To diagnose ARDS, your doctor may have you undergo some of the following tests and procedures. Different tests may be appropriate for different ages.
- Blood teststo measure the oxygen level in your blood using a sample of blood taken from an artery.A low blood oxygen level might be a sign of ARDS. In order to confirm the cause of your symptoms, your doctor may also check your blood for signs of infection or a heart problem, or to see how well other organs are working.
- Chest X-ray to create detailed images of the inside of your chest. This test is generally the standard for showing excess fluid in your lungs.
- CT scan of the chest or abdomen to create detailed images of your lungs or check for abdominal infections.
- Other tests of blood oxygen levels, such as pulse oximetry, that do not require collecting a blood sample. For these tests, a sensor is attached to the skin or placed on a hand or foot.
Prevent Copd Before It Starts
The best way to prevent COPD is to not start smoking or to quit smoking. Smoking is the leading cause of COPD. If you smoke, talk with your doctor about programs and products that can help you quit.
If you have trouble quitting smoking on your own, consider joining a support group. Many hospitals, workplaces, and community groups offer classes to help people quit smoking. Ask your family members and friends to support you in your efforts to quit.
Also, try to avoid lung irritants that can contribute to COPD, such as air pollution, chemical fumes, dusts, and secondhand smoke, which is smoke in the air from other people smoking.
For more information about how to quit smoking, go to the Health Topics Smoking and Your Heart article and the National Heart, Lung, and Blood Institute’s Your Guide to a Healthy Heart. Although these resources focus on heart health, they include basic information about how to quit smoking. For free help and support to quit smoking, you may call the National Cancer Institutes Smoking Quitline at 1-877-44U-QUIT .
I Had Never Seen Something Like This
The Washington Post reported in July that pathologists are learning, through autopsies, about other effects of COVID-19, such as microclots in the lungs and other organs. Some of these microclots appear to start early on in an infection.
One pathologist from Louisiana, Richard Vander Heide, who has been performing autopsies since 1994, told the Washington Post, I had never seen something like this. His autopsies on people who had died from COVID-19 found a pattern of hundreds or thousands of microclots in the lungs. His discovery has led to medical treatment of blood thinners for COVID-19 patients.
Other effects on organs include brain damage from oxygen deprivation and microclots in the brain.
This doesnt happen in every COVID-19 case. We know that most people who develop COVID-19 will have mild or no symptoms. Most people will survive.
But we still dont know what it truly means to recover from COVID-19. Some people who survive a case of COVID-19 return to normal, healthy lives.
Some still experience a loss of smell and taste for months afterward. Others, who have become known as long-haulers, continue to have medical struggles for many months after an initial infection and continue to experience coughing, tightness in the chest, shortness of breath, diarrhea and fatigue.
The medical science community is still learning more about why this is happening, and we hope to have more certainty one day.

Early Symptoms Of Covid
The infection starts off with mild flu-like symptoms or no symptoms and further progresses to severe symptoms. Initially, COVID-19 infects the lung in the affected individual and, in severe cases, causes death due to ARDS and pneumonia. However, it is important to remember that COVID-19 does not lead to ARDS and pneumonia in all cases.
Worldwide, it has been observed that most people infected with coronavirus will exhibit mild symptoms, 13 per cent will have pneumonia, 5 per cent will suffer from septic shock and organ failure and 2 per cent of cases may result in fatality.
Some of the primary symptoms to look for in COVID-19 patients are fever, breathing problems, headache, dry cough and in a few cases it may cause loss of smell and taste. Some patients could experience diarrhea and fatigue as primary symptoms.
Can Coronavirus Patients Lessen The Chance Of Lung Damage
There are things patients can do to increase their chances for less severe lung damage, Galiatsatos says.
If you have a health issue that puts you at higher risk, make sure youre doing everything you can to minimize the chance of contracting the virus. Also, make sure that your chronic health conditions are managed as well as they can be. For example, people living with diabetes, COPD or heart disease should be especially careful to manage those conditions with monitoring and taking their medications as directed.
Galiatsatos adds that proper nutrition and hydration can also help patients avoid complications of COVID-19. Staying well fed is important for overall health. Proper hydration maintains proper blood volume and healthy mucous membranes in the respiratory system, which can help them better resist infection and tissue damage.
Coronavirus: Smoking, Vaping, Wildfire Smoke and Air Pollution
Our expert, Panagis Galiatsatos, M.D., M.H.S. discusses how smoking, vaping and air pollution might increase the severity of COVID-19. Learn about how each of these could affect a COVID-19 diagnosis.
Staying Safe Against Covid
While a vaccine for Covid 19 is still under work and might take a while before it is tested and certified for usage, our best bet right now is to stay safe, stay indoors and avoid crowds. A few simple precautions like maintaining hygiene and sanitizing your environment will go a long way in countering the spread of Covid 19 infection.
Knock Out A Sore Throat
If you do have a sore or scratchy throat, it is important to soothe it so that throat irritation doesnt migrate down to the lungs. Drink warm liquids like water with a squeeze of lemon, a dash of apple cider vinegar, or sprinkle of Himalayan sea salt, along with green tea, matcha, weak black coffee, or another elixir. Warm liquids not only soothe the throat, but they also increase hydration and the flow of gastric juices in the stomach, helping reduce inflammation.

Covid Pneumonia: How Long Does Recovery Take
You’re likely familiar with the common, mild symptoms of COVID-19 including fever, dry cough and fatigue.
But, in more severe cases, COVID-19 can also cause serious complications, including pneumonia.
“We still have a lot to learn about COVID-19, particularly about the havoc it can wreak on the lungs and the pneumonia it causes, which is often now called COVID pneumonia,” says Dr. Rayman Lee, pulmonologist at Houston Methodist.
That being said, there’s still plenty that experts like Dr. Lee do know about COVID pneumonia, including about how long it can take to fully recover from it.
Symptoms To Watch Out For
Patients who have tested positive for COVID-19 will have symptoms like dry cough, breathlessness, fever, loss of sense of taste and smell, tiredness and chest pain amongst others.
In case the infection has spread to the lungs, it may show symptoms like persistent cough and fever, chest discomfort, breathless on exertion, low oxygen saturation and blood inflammatory markers mentioned above. “It usually happens after five days of the infection,” Dr Tickoo adds.

Mild And Moderate Cases
As the infection travels your respiratory tract, your immune system fights back. Your lungs and airways swell and become inflamed. This can start in one part of your lung and spread.
Doctors can see signs of respiratory inflammation on a chest X-ray or CT scan. On a chest CT, they may see something they call ground-glass opacity because it looks like the frosted glass on a shower door.
Medical History And Physical Exam
- Exposure to sick people at home, school, or work or in a hospital
- Flu or pneumonia vaccinations
- Exposure to birds and other animals
During your physical exam, your doctor will check your temperature and listen to your lungs with a stethoscope.

Loss Of Appetite And Weight Loss
While youre recovering form COVID-19, you might find that you have less of an appetite than usual. You might also have difficulty swallowing, which could affect how much food and drink youre able to have.
Its important to try to eat and drink as much as you need, as this can affect your mood, energy levels and your overall recovery from COVID-19.
Theres more advice on eating well to recover from COVID-19 in the recovery guide from the Lancashire Teaching Hospitals NHS Foundation Trust.
You Might Cough Up Blood
Some long haulers cough so much, they cough up blood. “This is 18 weeks,” Marjorie Roberts, 59, a life coach, told NPR about her Long COVID. “This is 18 weeks that I have been suffering. The shortness of breath comes when it wants todon’t know which symptom is going to come back. If I have a headache, I get scared because I know the headache can be so intense. If I cough too much, I cough up blood. And I just pray that they find a cure.”

Whats The Connection Between Coronavirus And Ards
As Dr. Mukhopadhyay explains, Chinese researchers have linked COVID-19 to ARDS. Their study examined risk factors for 191 confirmed coronavirus patients who died while being treated in two hospitals in Wuhan, China.
The researchers found 50 of the 54 patients who died had developed ARDS while only nine of the 137 survivors had ARDS.
Its a really, really significant contribution to death in these patients, says Dr. Mukhopadhyay.
Children Just As Susceptible
Studies conducted during the early stages of the pandemic suggest that children and teenagers have markedly lower susceptibility to the virus than adults.
Dr. Demet Toprak is an assistant professor of pediatrics at the University of Washington School of Medicine and medical director of the Pulmonary Diagnostic Lab at Seattle Childrens Hospital.
She offered an explanation in an interview with Medical News Today, With the lockdown that happened very early during the pandemic, obviously, families protected their kids much better than they protected probably themselves or the adult population.
Dr. Toprak also mentioned: The pediatric patients actually do not have a very good cohort, the numbers were less, we didnt have an overwhelming number of patients to start with that had COVID-19 and needed support. I dont know what would happen over the next year.
Later research involving systematic testing has estimated that infection rates in younger people are comparable with or even higher than in adults.

Disease Severity Of Covid
SARSCoV2 is a highly contagious virus that causes COVID-19. This virus is extremely potent, causing a wide range of symptoms affecting multiple organs. Once it is transmitted to our body, it begins attaching to internal organs, including the lungs, heart, intestines and vessels including renal vessels . Next step involves host cell penetration, leading to viral replication as virus continues multiplying and infecting more cells in the body. Once the viral multiplication reaches certain levels, a large amount of virus starts causing cell destruction and spreading to adjacent organs. As the virus speedily multiplies, organ damages continue progressively. Without prompt and appropriate treatments, it might lead to a fatal consequence due to multiple organ failure.
COVID-19 can cause lasting lung damages. The effect on the respiratory system mainly involves lung infections, resulting in an impaired oxygen exchange process. Once the lung tissue becomes damaged and cannot be oxygenated adequately, the oxygen level in the blood significantly reduces.
If You Are Treated In The Hospital
There is currently one drug that has been approved by the Food and Drug Administration to treat COVID-19.
- Remdesivir, an antiviral which has been shown to shorten the recovery time needed in some hospitalized patients
The FDA has also issued emergency use authorization for certain medications that your healthcare provider may prescribe as treatment of COVID-19. Depending on your situation, you may receive:
- Dexamethasone, a corticosteroid used to prevent or reduce inflammation in hospitalized patients with severe illness who need supplemental oxygen
- Tocilizumab, a biological therapy used to reduce inflammation in hospitalized patients with severe illness requiring oxygen delivery through a high-flow device, invasive mechanical ventilation or ECMO, if used in addition to dexamethasone
The Centers for Disease Control and Prevention regularly updates treatment recommendations based on the expert panel at the National Institutes of Health who have developed and regularly update the NIH COVID-19 Treatment Guidelines.
Supportive care is given for mild to severe symptoms. Supportive care means treating the symptoms while the disease runs its course.

Three Factors In Coronavirus Lung Damage
Galiatsatos notes three factors that affect the lung damage risk in COVID-19 infections and how likely the person is to recover and regain lung function:
Disease severity. The first is the severity of the coronavirus infection itself whether the person has a mild case, or a severe one, Galiatsatos says. Milder cases are less likely to cause lasting scars in the lung tissue.
Health conditions. Galiatsatos says, The second is whether there are existing health problems, such as chronic obstructive pulmonary disease or heart disease that can raise the risk for severe disease. Older people are also more vulnerable for a severe case of COVID-19. Their lung tissues may be less elastic, and they may have weakened immunity because of advanced age.
Treatment. Treatment is the third factor, he says. A patients recovery and long-term lung health is going to depend on what kind of care they get, and how quickly. Timely support in the hospital for severely ill patients can minimize lung damage.
How To Keep Your Lungs Strong For Covid
An offense is the best defense for maintaining your lung health during the COVID-19 pandemic.
During this unprecedented time, it is important to not only stay home and work safely whenever and wherever possible, but it is also critically important to keep your lungs and immune system healthy to improve your bodys ability to fight off infection or illness.
We know that the SARS-CoV-2 virus that causes COVID-19 disease obstructs respiratory pathways with very thick mucus. In order for medicines and treatments to work, the airways must be open and unblocked. This takes a number of days.
In order to actively fight off any viral infection, including this one, the best offense is healthy lungs.
Here are some proactive steps you can take to optimize your pulmonary health.

Like An Elephant Sitting On My Chest
Don Van Gilder knows what its like to have lungs filled with fluid because of COVID-19.
It felt like an elephant sitting on my chest. It was not pleasant. The chest pains were so bad I was worried I might be having a heart attack, Van Gilder said.
Van Gilder spent five days in the hospital primarily because of a reaction to the steroids he was taking because of COVID. But he said the days leading up to that hospital stay were even worse.
Days nine, 10 and 11 felt like the three worst days of my life, he said.
Van Gilder says he barely moved for days.
I alternated between praying I would live or that I would just die and be done with it, Van Gilder said.
Lung Inflammation And Scarring
In severe cases, the lungs may become scarred. The scarring causes stiffness in the lungs, which can make it difficult to breathe and get oxygen to the bloodstream, resulting in long-term breathlessness and difficulty managing daily tasks.
This inflammation and scarring of the lungs is called interstitial lung disease.
Now, this study, called the UK Interstitial Lung Disease Long-COVID19 study, will investigate:
- whether post-COVID-19 lung damage will improve or worsen over time
- how long it will last
- the best strategies for developing treatments.
Early evidence indicates that lung damage occurs in approximately 20% of patients discharged from hospital, but the effects on people who experience Long-COVID in the community are currently unclear.

How Can Doctors Tell If You Have Ards
If you have ARDS, youll have symptoms like sudden breathlessness, rapid breathing, dizziness, rapid heart rate and excessive sweating.
But the four main things doctors will look for are:
- If you have an acute condition, symptoms that started within one week of what they call a known clinical insult, or new or worsening symptoms.
- If your shortness of breath isnt explained by heart failure or fluid overload.
- Having low oxygen levels in your blood .
- Both lungs appearing white and opaque on chest X-rays .
Muscle Weakness And Stiff Joints
While youre recovering from COVID-19, youre likely to be less active than usual. This can cause your muscles to become weak and stiff, and you might start getting aches and pains. This could also be a side effect of some of the treatments you received while you were ill with COVID-19, as they may have out extra strain on your joints and muscles.
All this might mean youre less able to do the things you usually do, like going up stairs, raising your arms above your head and gripping objects.
To find out more about joint and muscle problems after COVID-19, take a look at the Your COVID Recovery website.
