A comprehensive guide to pulse oximeters

  What is a pulse oximeter? A pulse oximeter is a small device that quickly and painlessly measures the oxygen saturation level (SpO2) in your blood and your pulse rate (heart beats per minute). Portable and easy to use, it clips comfortably on your fingertip. The reading of your oxygen saturation levels and heart rate are displayed on the LED screen of the device. Pulse oximeters are used by medical professionals who need a quick and easy method of measuring SpO2 levels and pulse rates. They are widely used in hospitals and healthcare clinics to assess the health status of people with respiratory conditions such as asthma, lungs disorders and heart diseases. They are also used by people who participate in sports activities – they can help you to see how your oxygen intake changes before and after a workout as well as how the exercise affected your heart rate. More recently, they have become a popular medical device to monitor oxygen levels of people with the COVID 19 infection, a...

Investigating techno-economic effects and environmental impacts of energy renovation of residential building clusters on a district heating system

  Abstract Studying energy renovation of older residential building stocks together with the surrounding district heating (DH) system is essential to fully understand implications from a reduced district heat demand and for involved actors. This study reveals the benefit of integrating the simulation and optimization tools OPERA-MILP, IDA ICE, and MODEST to investigate thoroughly the effect of energy renovation strategies on heat load supply, building and DH system-based life cycle costs (LCCs), primary energy use, and total of direct and indirect CO 2  emissions. Energy renovation considered different cluster combinations of slab and tower blocks of a stock of 343 apartment buildings in two Swedish municipalities and strategies for lowest LCC and code compliance.  1. Introduction The efficient use of energy in the European Union (EU) is a main topic to protect the environment, mitigate climate change, and reduce reliance on external supplies. With approx. 40% of EU...

Effect of transitioning to automatic milking systems on producers' perceptions of farm management and cow health in the Canadian dairy industry

INTRODUCTION When functioning optimally, an  automatic milking system  ( AMS ) permits cows to voluntarily visit a robotic milking unit multiple times per day to be milked without requiring human labor. Demonstrated benefits of AMS include increased milk production, improved cow comfort, a more flexible lifestyle for producers, less labor for milking, as well as improved cow health and more interesting or less routine activities for the producer. However, an AMS has higher capital costs, requires producers to be on-call, and changes management to be more data-based. Profitability or labor savings with AMS varies depending on the management capabilities of producers. Although Europe has the highest concentration of AMS dairy farms, this technology is becoming increasingly common in Canada. The proportion of dairy farms in Canada that use AMS has grown from 5.6% in 2014 to 6.8% in 2015. Despite this growing popularity, little documentation exists on how AMS has affected Nor...
