What Do You Buy The Person Who Has Everything
A pulse oximeter is a quick reading of the oxygen concentration in the blood. Some doctors believe it is a useful tool at home during the coronavirus pandemic. Others aren’t so sure.

As the coronavirus continues to spread, a small medical device called a pulse oximeter has started flying off the shelves. In fact, the demand has grown so incredibly that you won’t even be able to buy it at your local drugstore or online.
How much does the device cost in this disease? Do you need one at home? The first question is easy to answer. The second is more difficult.
A pulse oximeter is a small electronic device that measures the amount of oxygen in your blood. You want a number in the 95% to 100% range. If the number drops to 92% or less, it’s a concern. It is at this level that the doctor sends you extra health and you stay in the hospital for observation.

To get that pulse, a device is attached to your finger or ear and delivers different wavelengths of light through tiny capillaries, says Dr. Richard Levitan, an emergency room physician in New York City. Hampshire specializes in runway management. (For a really good scientific explanation, read this.)
The term for low blood pressure is hypoxemia. In this situation, your body’s organs may not work properly. Severe cases can affect the functioning of the heart or brain.
Your blood oxygen is monitored with a pulse oximeter. It is used in some physical examinations and is considered important in management and intensive care. The device will also give you your heart rate.
COVID-19 can cause what’s called COVID pneumonia — a disease in which the air sacs in the lungs fill with fluid or pus. And it’s possible for a person infected with the new coronavirus to be in the early stages of COVID pneumonia — including low blood oxygen levels — without breathing problems.

In these situations, a pulse oximeter may indicate that you are in trouble before you know it. That’s what Levitan saw when he spent 10 days working in the ER at Bellevue Hospital in New York City earlier this month: Many COVID patients were already dying of COVID pneumonia by the time they arrived. They are breathing rapidly and the oxygen level in their blood is very low. Like mountain climbers, patients are used to gradually decreasing oxygen levels and are unaware that they are in trouble.
Many of them said they had just started breathing, despite having had symptoms of COVID-19 for days. By the time the patients got to the hospital, Levitan said, the virus had already damaged their lungs and many became seriously ill. He has seen COVID-19 patients with air pollution levels as high as 50 percent.
“These COVID patients have adapted to this slow pace and reduced oxygen that they don’t know,” he said. “Then come in with a sigh, it’s been a long time. He believes a pulse oximeter can detect early warning signs of low blood oxygen levels.
The disease “kills silently with oxygen depletion. When you get to the end of the illness, like anyone who goes to the ER, there’s a high risk,” he said. each one.
Your Work Peak Is Earlier Than You Think
According to Levitan in medicine, the earlier the treatment, the better the results – “the same applies to Covid”.
Levitan thinks it’s a good idea to keep a pulse oximeter at home during the flu — as well as a thermometer for monitoring fevers. If you have symptoms of COVID-19, such as weakness, muscle aches or fever, you can use the device to measure your blood oxygen levels, he said.
A 92% (or less) chance is “You should be evaluated because this disease will be silent and you won’t be able to breathe much.” (Although people in high places have levels “in the low 90s, that’s fine,” he added.)
Dr. Elisa Perkins, professor of emergency medicine at Boston Hospital, does not recommend that everyone buy a pulse oximeter. He worries that people will rely on the device’s data instead of calling a doctor if they’re sick.

“I think it’s a no-brainer that these things should be in the house,” Perkins said, though he knows why people want them.
“In general, I honestly think if people are experiencing symptoms or shortness of breath, they should see a doctor if possible,” she says. “Most or many places now offer home visits, telehealth visits, that can show conditions that affect someone other than just a number that’s on a pulse oximeter.”
But he’s not completely against home pulse oximeters. If you have symptoms similar to the new coronavirus, using a pulse oximeter, he said
It has one risk: many people can be persuaded into thinking that they are not really sick. People with COVID are “very thirsty and very weak,” Perkins said. “We’ve seen people who are tired, have no respiratory symptoms and no breathing problems.

Another concern. The reading will be less accurate if the person wears nail polish or artificial nails, has cold hands, or has poor circulation.
It’s possible to misread the numbers and panic based on how old they look. Or the device itself is faulty.
Albert Rizzo, the American Lung Association’s chief medical officer, issued a statement Thursday urging people to “needlessly sell pulse oximeters.”
“Unless you’ve had a heart attack or a heart attack related to oxygen levels on a regular basis, most people don’t want to have a pulse oximeter in their home,” Rizzo said. Most importantly, if you wish to purchase a pulse oximeter for home use, please discuss the need and use of the device with your healthcare provider. A healthcare professional can make a decision if this is helpful and provide guidance on interpretation. Readings in the context of your situation. Use your pulse oximeter reading and other symptoms like shortness of breath, fever, fatigue as signs to see your doctor.”
Coronavirus Faqs: What Is A Pulse Oximeter? Why Are So Many People Buying One?
Abraar Karan, an internal medicine physician at Brigham and Women’s Hospital and Harvard Medical School, is an advocate of caution when it comes to home use pulse oximeters. He said it remains to be seen how low oxygen levels can be predicted to accurately identify patients at risk of death. He pointed to a recent study looking at 5,700 patients hospitalized with COVID-19 in New York City, which found that only 27.8% needed supplemental oxygen at the time of the test.
“What we don’t want to happen is for people to get really upset but think that just because a home oximeter reads well, it’s OK,” Karan wrote in an email. “We need to make sure patients are using the pulse oximeter correctly and reading it correctly — otherwise, more people are coming to the emergency room who may not make it there.”
But Levitan says it already puts a lot of pressure on the ER when people misinterpret a home blood pressure monitor or thermometer. According to Levitan, the bigger concern is those who die suddenly from COVID. And he’s not worried that the device is just making people nervous: “You know what? We’re scared. We’re anxious. We need validation.”

A For And Against Essay About The Internet
If you think a pulse oximeter is expensive, Levitan says you should buy one from a medical source like a pharmacy, not some random place on the Internet — it’s a good idea to find one that’s FDA-approved, if possible. You can go to the FDA’s Premarket 510(k) Notice page and search for “oximeter.”
