Diving physiology in penguins has been extensively studied in the larger, deep diving species similar to emperor and gentoo penguins, nonetheless the blood oxygen storage capacity of the mid-depth diving crested penguins is less understood. For this mission, 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 compare oxygen storage capacity and dive depth/time. Data evaluation for this undertaking continues to be underway, but preliminary results counsel that the bigger erect-crested penguin has the best hemoglobin and hematocrit values of the three suggesting the next oxygen storage capacity within the blood and BloodVitals SPO2 more efficient transport of oxygen to the tissues allowing 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 be aware containing these values is on deck for Notornis.

The Apple Watch Series 6 feels prefer it has perfected many of the options I appreciated about its predecessor. It has a brighter all the time-on display, a more powerful processor, sooner charging and two new colorful choices to select from. But the function I was most excited to try out was its new sensor that measures oxygen saturation in the blood (aka SpO2) with the tap of a screen. As somebody who panic-purchased a pulse oximeter at the start of the coronavirus pandemic and BloodVitals SPO2 device nonetheless checks her ranges at the first sign of a cough, the thought of getting one strapped to my wrist always was enough to pique my interest. But in contrast to the ECG function 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, BloodVitals SPO2 on the Apple Watch still seems to be in its early phases. Navigating all this new knowledge could be daunting for anyone who's not a medical professional.

I purchased an FDA-cleared pulse oximeter, the machine doctors use to measure BloodVitals SPO2 on your fingertip, as a precaution when coronavirus circumstances within the US started to climb. Having low blood oxygen ranges does not guarantee you've got COVID-19, however it is one of the most important symptoms of the disease. I had learn horror stories of people who waited too lengthy to go to the hospital and had died of their sleep as a result of they didn't understand their levels had dipped overnight. You need to at all times check with a physician if you are experiencing shortness of breath (one other symptom of COVID-19), even when a pulse oximeter says you're in a healthy range, however I discovered consolation in figuring out that I might no less than use it as a reference if I ever skilled shortness of breath. That's not one thing you can do with the Apple Watch -- Apple says it should be used for wellness functions only and not as a medical machine, that means you will must 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 other advantages of getting it strapped on your wrist always. Much like a pulse oximeter, the Series 6 makes use of red and infrared gentle from its new sensor BloodVitals SPO2 device to find out the percentage of oxygen in the blood. But as a substitute of shining the light via your fingertip, it makes use of the light that's reflected back from the blood vessels in your wrist to find out your oxygen levels primarily based on the coloration of your blood. Throughout the setup process you're requested whether or not or not you need to activate BloodVitals SPO2 device tracking, which I did, however you possibly can always return and disable it in the settings after the actual fact. The first thing I did after strapping on the Watch was open the Blood Oxygen app. It gives you a couple of recommendations on easy methods to get the most effective result and you have to relaxation your arm on a table or flat floor whereas the Watch is taking a studying.

Then the 15-second countdown begins and you're finished -- straightforward and painless. I got a 95% on my first learn, which was decrease 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, but normally, larger is better. I tested it just a few more occasions and received barely totally different outcomes within a few share points relying on whether I was completely nonetheless and silent throughout the take a look at, where I had the watch positioned on my wrist and BloodVitals SPO2 device the way tight the strap was. There are various elements that can have an effect on a studying, reminiscent of pores and skin temperature or BloodVitals SPO2 device 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 points, however typically spot on. What was extra interesting to me was the SpO2 knowledge that collected over time within the Health app .
