What's a Cc of Blood? A "cc" of blood is 1 cubic centimeter of blood. A cubic centimeter is equal to 1 milliliter. The common human has about 5,000 cubic centimeters of blood. Blood is a vital component in the human body that distributes nitrogen, oxygen and other nutrients to important organs. Blood is composed of plasma and blood cells. Plasma contains proteins that help in blood clotting throughout damage. About half of blood volume is made up of blood cells. Red blood cells carry oxygen to tissues and organs, white blood cells combat infections and platelets help in blood clotting. The American Red Cross collects approximately 15.7 million blood donations yearly in the United States. About 1 pint, BloodVitals insights or 473 cubic centimeters, of blood is collected throughout the donation. Based on the American Red Cross, one blood donation can save up to a few lives, as crimson blood cells, platelets and plasma can be utilized individually from the blood.



The Apple Watch Series 6 feels prefer it has perfected many of the options I liked about its predecessor. It has a brighter always-on show, a extra highly effective processor, sooner charging and two new colorful options to select from. But the characteristic I was most excited to check out was its new sensor that measures oxygen saturation in the blood (aka BloodVitals SPO2) with the faucet of a display screen. As someone who panic-purchased a pulse oximeter initially of the coronavirus pandemic and still checks her levels at the first sign of a cough, the thought of getting one strapped to my wrist at all times was sufficient to pique my interest. But unlike the ECG feature on the Apple Watch, which has been tried, examined and cleared by the US Food and Drug Administration, together with the irregular coronary heart rhythm notifications, BloodVitals SPO2 on the Apple Watch still appears to be in its early levels. Navigating all this new data may be daunting for anyone who's not a medical professional.



I bought an FDA-cleared pulse oximeter, the system docs use to measure BloodVitals SPO2 in your fingertip, as a precaution when coronavirus instances within the US began to climb. Having low blood oxygen ranges doesn't guarantee you've gotten COVID-19, but it is one among the foremost signs of the disease. I had read horror stories of people that waited too lengthy to go to the hospital and had died in their sleep because they didn't realize their levels had dipped in a single day. You should at all times test with a physician if you're experiencing shortness of breath (another symptom of COVID-19), even if a pulse oximeter says you are in a wholesome vary, BloodVitals insights but I found comfort in knowing that I might at the least use it as a reference if I ever skilled shortness of breath. That's not one thing you are able to do with the Apple Watch -- Apple says it ought to be used for wellness purposes only and not as a medical gadget, meaning you may must take the results with a grain of salt and shouldn't use it to display screen for any type of disease, which is what I had been hoping to get out of it.



But there could also be other advantages of getting it strapped in your wrist at all times. Very like a pulse oximeter, the Series 6 uses red and infrared light from its new sensor to find out the percentage of oxygen within the blood. But as an alternative of shining the light by your fingertip, it uses the light that's mirrored back from the blood vessels in your wrist to find out your oxygen ranges based on the coloration of your blood. In the course of the setup process you are asked whether or not you need to activate BloodVitals SPO2 tracking, which I did, but you'll be able to all the time go back and disable it in the settings after the fact. The first thing I did after strapping on the Watch was open the Blood Oxygen app. It offers you just a few recommendations on learn how to get the most effective outcome and you have to rest your arm on a table or flat floor whereas the Watch is taking a studying.



Then the 15-second countdown begins and you are executed -- easy and painless. I received a 95% on my first read, which was lower than what I'm used to from my pulse oximeter. Anything above 90% is mostly considered by clinicians to be within a healthy vary, but normally, increased is healthier. I tested it a few more times and obtained slightly totally different outcomes within just a few proportion factors depending on whether I used to be utterly nonetheless and silent throughout the check, the place I had the watch positioned on my wrist and the way tight the strap was. There are many factors that may have an effect on a studying, such as skin temperature or the place of the sensors on the physique. Side-by-facet with my pulse oximeter, the Apple Watch was usually off by about one or two factors, however sometimes spot on. What was more attention-grabbing to me was the BloodVitals SPO2 information that collected over time in the Health app .
