Diving physiology in penguins has been extensively studied in the larger, deep diving species such as emperor and gentoo penguins, nevertheless the blood oxygen storage capacity of the mid-depth diving crested penguins is much less understood. For  [[https://dev.neos.epss.ucla.edu/wiki/index.php?title=User:VeroniqueRubeo7|measure SPO2 accurately]] this venture, I measured the concentrations of hemoglobin and hematocrit in three species of crested penguins (Fiordland penguin/tawaki, erect-crested penguin, and Eastern rockhopper penguin) in New Zealand to check oxygen storage capacity and dive depth/time. Data analysis for this venture continues to be underway,  [[https://wiki.apeconsulting.co.uk/index.php/User:Gordon7101|measure SPO2 accurately]] however preliminary outcomes recommend that the larger erect-crested penguin has the best hemoglobin and hematocrit values of the three suggesting a higher oxygen storage capability within the blood and more efficient transport of oxygen to the tissues allowing deeper or longer dives. Data from this venture was cited in New Zealand Geographic 2023 article The future is Written in Penguin Blood (see Media tab for hyperlinks). Publication of a brief word containing these values is on deck for Notornis.

The Apple Watch Series 6 feels like it has perfected lots of the features I liked about its predecessor. It has a brighter always-on show, a extra highly effective processor, quicker charging and two new colorful options to choose from. But the characteristic I was most excited to check out was its new sensor that measures oxygen saturation within the blood (aka SpO2) with the tap of a screen. As someone who panic-purchased a pulse oximeter initially of the coronavirus pandemic and nonetheless checks her levels at the first sign of a cough, the thought of getting one strapped to my wrist at all times was enough to pique my curiosity. But in contrast to the ECG characteristic on the Apple Watch, which has been tried, examined and cleared by the US Food and Drug Administration, along with the irregular heart rhythm notifications, [[https://webtily.me/darcykabu31997|BloodVitals SPO2]] on the Apple Watch nonetheless seems to be in its early phases. Navigating all this new knowledge will be daunting for anybody who's not a medical skilled.



I bought an FDA-cleared pulse oximeter,  [[https://stir.tomography.stfc.ac.uk/index.php/Blood_Clots:_Four_Signs_You_Can_Have_One|measure SPO2 accurately]] the gadget medical doctors use to [[https://code.zwerer.com/sherlynmsu0663|measure SPO2 accurately]] [[http://cara.win/margeneclore5|BloodVitals SPO2]] on your fingertip, as a precaution when coronavirus instances within the US started to climb. Having low blood oxygen ranges doesn't guarantee you've gotten COVID-19, however it is one in every of the major signs of the disease. I had learn horror stories of people that waited too lengthy to go to the hospital and had died in their sleep as a result of they didn't understand their ranges had dipped in a single day. You need to always test with a physician if you are experiencing shortness of breath (another symptom of COVID-19), even if a pulse oximeter says you're in a wholesome vary, but I found consolation in realizing that I may no less than use it as a reference if I ever skilled shortness of breath. That's not something you can do with the Apple Watch -- Apple says it must be used for wellness purposes solely and not as a medical machine, that means you'll must take the results with a grain of salt and should not use it to screen for any type of disease, which is what I had been hoping to get out of it.



But there may be other advantages of getting it strapped in your wrist at all times. Very like a pulse oximeter, the Series 6 makes use of purple and infrared mild from its new sensor to determine the percentage of oxygen in the blood. But instead of shining the light via your fingertip, it uses the sunshine that is reflected again from the blood vessels in your wrist to find out your oxygen levels based mostly on the coloration of your blood. Throughout the setup process you're requested whether or not you want to activate [[https://fs-biolink.com/charmainjeffri|BloodVitals SPO2]] tracking, which I did, but you may all the time return and disable it in the settings after the actual fact. The very first thing I did after strapping on the Watch was open the Blood Oxygen app. It gives you just a few recommendations on tips on how to get the perfect outcome and you'll want to relaxation your arm on a desk or flat floor whereas the Watch is taking a studying.



Then the 15-second countdown begins and you're done -- straightforward and painless. I received a 95% on my first learn, which was lower than what I'm used to from my pulse oximeter. Anything above 90% is generally thought-about by clinicians to be inside a healthy vary, however normally, increased is better. I tested it a couple of extra times and obtained barely completely different outcomes within a number of share points depending on whether I used to be fully still and silent through the test,  [[https://ushort.xyz/collettefelix6|BloodVitals SPO2]] the place I had the watch positioned on my wrist and how tight the strap was. There are lots of components that may affect a reading, akin to skin temperature or the position of the sensors on the physique. Side-by-side with my pulse oximeter, the Apple Watch was typically off by about one or two factors, however typically spot on. What was more interesting to me was the [[https://bk-house.synology.me:3081/karlcanchola77|BloodVitals SPO2]] knowledge that collected over time within the Health app .
