Diving physiology in penguins has been extensively studied in the bigger, deep diving species corresponding to emperor and gentoo penguins, nonetheless the blood oxygen storage capacity of the mid-depth diving crested penguins is much less understood. For BloodVitals SPO2 this undertaking, I measured the concentrations of hemoglobin and hematocrit in three species of crested penguins (Fiordland penguin/tawaki, erect-crested penguin, and BloodVitals SPO2 Eastern rockhopper penguin) in New Zealand to check oxygen storage capability and dive depth/time. Data evaluation for this challenge remains to be underway, but preliminary outcomes suggest that the larger erect-crested penguin has the very best hemoglobin and hematocrit values of the three suggesting a better oxygen storage capacity within the blood and more efficient transport of oxygen to the tissues permitting deeper or BloodVitals SPO2 longer dives. Data from this mission was cited in New Zealand Geographic 2023 article The future is Written in Penguin Blood (see Media tab for links). Publication of a short word containing these values is on deck for Notornis.



The Apple Watch Series 6 feels like it has perfected many of the options I preferred about its predecessor. It has a brighter at all times-on show, a extra highly effective processor, faster charging and two new colorful choices to choose from. But the feature I used to be most excited to check out was its new sensor that measures oxygen saturation within the blood (aka BloodVitals SPO2) with the faucet of a display screen. As somebody who panic-bought a pulse oximeter initially of the coronavirus pandemic and still checks her levels at the primary sign of a cough, painless SPO2 testing the thought of having one strapped to my wrist always was sufficient to pique my curiosity. But unlike the ECG feature on the Apple Watch, which has been tried, tested 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 stages. Navigating all this new knowledge might be daunting for anybody who's not a medical professional.



I bought an FDA-cleared pulse oximeter, the machine doctors use to measure BloodVitals SPO2 in your fingertip, as a precaution when coronavirus cases within the US started to climb. Having low blood oxygen levels does not guarantee you have COVID-19, but it is one in every of the main symptoms of the disease. I had learn horror stories of people who waited too long to go to the hospital and had died in their sleep as a result of they did not notice their ranges had dipped in a single day. You must all the time examine with a physician in case you are experiencing shortness of breath (one other symptom of COVID-19), even when a pulse oximeter says you're in a wholesome range, however I found comfort in realizing that I could at least use it as a reference if I ever experienced shortness of breath. That's not one thing you can do with the Apple Watch -- Apple says it ought to be used for wellness functions only and never as a medical device, which means you'll should take the results with a grain of salt and should not use it to screen for any sort of disease, which is what I had been hoping to get out of it.



But there could also be different advantages of getting it strapped on your wrist at all times. Very like a pulse oximeter, the Series 6 makes use of red and infrared gentle from its new sensor to find out the share of oxygen within the blood. But as an alternative of shining the light through your fingertip, it uses the light that's mirrored back from the blood vessels in your wrist to determine your oxygen ranges primarily based on the shade of your blood. Throughout the setup course of you're asked whether or not or not you need to activate BloodVitals SPO2 tracking, which I did, however you possibly can at all times return and disable it within the settings after the very fact. The first thing I did after strapping on the Watch was open the Blood Oxygen app. It provides you just a few recommendations on how one can get the most effective end result and you could rest your arm on a table or flat surface whereas the Watch is taking a studying.



Then the 15-second countdown begins and you are finished -- straightforward and painless. I acquired a 95% on my first learn, which was lower than what I'm used to from my pulse oximeter. Anything above 90% is mostly thought of by clinicians to be within a wholesome range, but generally, increased is healthier. I examined it a number of extra times and got slightly completely different outcomes within just a few share factors depending on whether I was fully still and silent during the test, the place I had the watch positioned on my wrist and how tight the strap was. There are many components that may affect a studying, similar to pores and BloodVitals SPO2 skin temperature or the place of the sensors on the physique. Side-by-facet 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 BloodVitals SPO2 information that collected over time in the Health app .
