| | Diving physiology in penguins has been extensively studied within the larger, deep diving species similar to emperor and gentoo penguins, nevertheless the blood oxygen storage capability 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 evaluation for this mission continues to be underway, however preliminary results counsel that the bigger erect-crested penguin has the best hemoglobin and hematocrit values of the three suggesting a better oxygen storage capacity in the blood and more environment friendly transport of oxygen to the tissues allowing deeper or longer dives. Data from this project 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 like it has perfected most of the options I preferred about its predecessor. It has a brighter all the time-on display, a extra powerful processor, sooner charging and [[https://git.vekus.ru/fletcher49i004|BloodVitals SPO2]] two new colorful options 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 faucet of a display. As somebody who panic-purchased a pulse oximeter in the beginning of the coronavirus pandemic and still checks her levels at the primary sign of a cough, the thought of getting one strapped to my wrist always 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, along with the irregular coronary heart rhythm notifications, SpO2 on the Apple Watch still appears to be in its early phases. Navigating all this new data will be daunting for anybody who's not a medical skilled. |

| | I purchased an FDA-cleared pulse oximeter, the machine docs use to measure SpO2 in your fingertip, as a precaution when coronavirus instances within the US began to climb. Having low blood oxygen ranges does not guarantee you might have COVID-19, however it is one of the major symptoms of the illness. I had read horror stories of people that waited too long to go to the hospital and had died of their sleep because they did not understand their ranges had dipped in a single day. It's best to always check with a physician if you're experiencing shortness of breath (one other symptom of COVID-19), even if a pulse oximeter says you're in a healthy vary, however I found consolation in knowing that I may 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 [[https://git.emoscape.org/cierraedge313|BloodVitals SPO2]] wellness purposes only and never as a medical device, which means you will must take the results with a grain of salt and [[https://rentry.co/19093-bloodvitals-spo2-the-ultimate-home-blood-monitoring-device|BloodVitals test]] should not use it to display for any kind of disease, which is what I had been hoping to get out of it. |

| | But there could also be other advantages of having it strapped in your wrist at all times. Very like a pulse oximeter, the Series 6 makes use of purple and infrared light from its new sensor to determine the proportion of oxygen in the blood. But as a substitute of shining the light by way of your fingertip, it uses the sunshine that is reflected again from the blood vessels in your wrist to determine your oxygen levels based mostly on the colour of your blood. In the course of the setup course of you are requested whether or not you want to activate SpO2 tracking, [[https://healthwiz.co.uk/index.php?title=Blood_Pressure_Monitoring_Testing_Market_Analysis_Forecast_2025|BloodVitals test]] which I did, but you possibly can at all times return and disable it within the settings after the fact. The very first thing I did after strapping on the Watch was open the Blood Oxygen app. It offers you just a few recommendations on the right way to get the most effective result and you'll want to rest your arm on a table or flat floor whereas the Watch is taking a reading. |

| | Then the 15-second countdown begins and you are accomplished -- easy 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 considered by clinicians to be inside a healthy vary, [[https://trevorjd.com/index.php/User:PoppyFuhrmann1|BloodVitals test]] but in most cases, [[http://zhadanchaoren.dhlog.com/viewthread.php?tid=108311&extra=|BloodVitals test]] increased is healthier. I tested it just a few extra times and got slightly different outcomes inside a number of proportion factors depending on whether I used to be completely nonetheless and silent throughout the check, where I had the watch positioned on my wrist and the way tight the strap was. There are various elements that may affect a reading, reminiscent of skin temperature or the position of the sensors on the body. Side-by-side with my pulse oximeter, the Apple Watch was often off by about one or two factors, but generally spot on. What was extra interesting to me was the SpO2 data that collected over time in the Health app . |
