Patients compensate for the low oxygen in their blood by breathing faster and deeper — and this happens without their realizing it. This silent hypoxia, and the patient’s physiological response to it, causes even more inflammation and more air sacs to collapse, and the pneumonia worsens until their oxygen levels plummet. In effect, the patient is injuring their own lungs by breathing harder and harder. Twenty percent of Covid pneumonia patients then go on to a second and deadlier phase of lung injury. Fluid builds up and the lungs become stiff, carbon dioxide rises, and patients develop acute respiratory failure. By the time patients have noticeable trouble breathing and present to the hospital with dangerously low oxygen levels, many will ultimately require a ventilator.
There are other things we can do as well to avoid immediately resorting to intubation and a ventilator. Patient positioning maneuvers (having patients lie on their stomach and sides) opens up the lower and posterior lungs most affected in Covid pneumonia. Oxygenation and positioning helped patients breathe easier and seemed to prevent progression of the disease in many cases. In a preliminary study by Dr. Caputo, this strategy helped keep three out of four patients with advanced Covid pneumonia from needing a ventilator in the first 24 hours. To date, Covid-19 has killed more than 40,600 people nationwide — more than 10,000 in New York State alone. Oximeters are not 100 percent accurate, and they are not a panacea. There will be deaths and bad outcomes that are not preventable. We don’t fully understand why certain patients get so sick, or why some go on to develop multi-organ failure. Many elderly people, already weak with chronic illness, and those with underlying lung disease do very poorly with Covid pneumonia, despite aggressive treatment. But we can do better. Right now, many emergency rooms are either being crushed by this one disease or waiting for it to hit. We must direct resources to identifying and treating the initial phase of Covid pneumonia earlier by screening for silent hypoxia.
这就是那个急诊医生在纽时发文说的silent hypoxia啊， Patients compensate for the low oxygen in their blood by breathing faster and deeper — and this happens without their realizing it. 也就是你的身体器官在compensate 但低血氧你自己是感觉不到的

同问
如果你阳性，但是无症状，还是每天测下好，等你有症状可能就来不及了。
没感染也没症状的不用测
需求上来了生产才会跟上。三四天前注意到有几个好评多的牌子在亚麻开始陆续上货了。就是比从前贵。

我用samsung 手机带的，还可以，新版的放在stress test里了
我也都买了。除了没想到美国疫情会这么厉害，酒精没买够。
我也是，真的感谢华人，我二月底就买了，amazon随便挑，买了俩，我们自己用一个，给婆婆随身带着一个。
这个普遍是通过夹手指头 手表夹不到吧。。。
谢谢
有的运动手环有这个功能
