Diving physiology in penguins has been extensively studied within the bigger, deep diving species resembling emperor and gentoo penguins, nevertheless the blood oxygen storage capacity of the mid-depth diving crested penguins is much less understood. For this challenge, 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 match oxygen storage capacity and dive depth/time. Data analysis for this undertaking continues to be underway, but preliminary outcomes suggest that the bigger erect-crested penguin has the highest hemoglobin and hematocrit values of the three suggesting a higher oxygen storage capability in the blood and more environment friendly transport of oxygen to the tissues permitting deeper or longer dives. Data from this undertaking was cited in New Zealand Geographic 2023 article The long run is Written in Penguin Blood (see Media tab for links). Publication of a short notice containing these values is on deck for Notornis.
The Apple Watch Series 6 feels prefer it has perfected many of the features I appreciated about its predecessor. It has a brighter all the time-on display, a extra powerful processor, sooner charging and two new colorful choices to select from. However the function I was 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. As someone who panic-bought a pulse oximeter in the beginning of the coronavirus pandemic and still checks her ranges at the first signal of a cough, the thought of having one strapped to my wrist at all times was sufficient to pique my interest. But not like the ECG function 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 nonetheless appears to be in its early levels. Navigating all this new data could be daunting for anyone who's not a medical professional.
I bought an FDA-cleared pulse oximeter, the device medical doctors use to measure BloodVitals SPO2 on your fingertip, as a precaution when coronavirus cases within the US started to climb. Having low blood oxygen levels does not guarantee you might have COVID-19, but it is one in all the foremost signs of the disease. I had read horror tales of people who waited too long to go to the hospital and had died in their sleep as a result of they did not understand their levels had dipped overnight. You need to all the time verify with a physician in case you are experiencing shortness of breath (one other symptom of COVID-19), even if a pulse oximeter says you are in a healthy range, however I found comfort in figuring out that I could at the very least use it as a reference if I ever experienced shortness of breath. That's not something you can do with the Apple Watch -- Apple says it ought to be used for wellness purposes only and not as a medical device, meaning you will should take the results with a grain of salt and should not use it to screen for any sort of illness, which is what I had been hoping to get out of it.
But there could also be different benefits of getting it strapped in your wrist always. Very similar to a pulse oximeter, the Series 6 uses red and BloodVitals tracker infrared light from its new sensor to find out the proportion of oxygen in the blood. But as a substitute of shining the sunshine by way of your fingertip, it uses the light that's mirrored again from the blood vessels in your wrist to find out your oxygen ranges primarily based on the shade of your blood. In the course of the setup course of you are requested whether or not you want to activate BloodVitals SPO2 monitoring, which I did, but you can all the time go back and disable it within the settings after the very fact. The very first thing I did after strapping on the Watch was open the Blood Oxygen app. It provides you a few tips on how one can get the best consequence and it's worthwhile to relaxation your arm on a desk or flat floor while the Watch is taking a reading.
Then the 15-second countdown begins and you're performed -- straightforward and painless. I bought 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 within a wholesome range, however usually, greater is best. I examined it a number of more times and got barely different outcomes within a number of percentage points depending on whether I used to be utterly still and BloodVitals tracker silent through the test, where I had the watch positioned on my wrist and how tight the strap was. There are various factors that may affect a reading, such as skin temperature or the position of the sensors on the body. 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 attention-grabbing to me was the BloodVitals SPO2 data that collected over time in the Health app .
