COVID-19 has been around for about three years, and it doesn’t plan to leave humanity alone soon. A new variant gains traction every few months and spreads worldwide like the original COVID-19. Now, as the world fights Omicron, we all need to make sure we can take care of ourselves and take accurate SPO2 readings.

If you don’t already have a pulse oximeter at home, we suggest buying one immediately. Doctors recommend regularly using pulse oximeters, as they can help you spot respiratory infections even before you feel out of breath. The earlier one detects a COVID-19 condition, the safer it is for the patient.

This awareness article will look at a few simple steps to teach you how to take accurate and reliable SPO2 readings using a pulse oximeter at home. Let’s begin!

Sit Upright

The first thing to get right is your sitting position. Sitting upright will keep your body relaxed and prevent the irregular flow of blood — preventing inaccurate heart rate and blood oxygen readings.

Insert Your Index Finger  

Place your finger inside the oximeter with the nail facing up. To elaborate, the fingernail would be on the same side as the oximeter’s display. Keep your hand steady for a precise reading, as unnecessary movements can affect accuracy.

Ideally, you should use the index finger on either of your hands as the testing site for an SPO2 reading utilising a pulse oximeter. Make sure you’re not wearing any pigments or nail polish. If the finger has some deformity, use the index finger on the other hand.

Prepare the Oximeter

Before reading, ensure the oximeter isn’t dusty and dirt-free. Sometimes, the photodetector or light source can be covered in dust particles, potentially leading to inaccurate readings.

Before using the pulse oximeter on a covid-infected patient (or potentially infected person with symptoms), try using it on a healthy family member to check if it returns regular readings. If the patient has already used the oximeter, do not use it on a fit family member.

For covid-infected patients, consider using a disposable masimo spo2 sensor to avoid spreading the virus.

Take the Reading

Leave the device on for at least a minute for maximum accuracy before taking your finger out. This allows the device to stabilize and record your readings when your hand is in a state of rest.

Moreover, avoid taking SPO2 readings under direct sunlight or any other direct light source. Since it takes readings based on light transmission, bright lights can affect the sensor’s accuracy. Some other factors, such as shivering or scarring on the skin, can also lead to false readings, so ensure you’re mindful of these factors.

Interpretation

A resting heart rate of 60 to 100 is considered normal. You should take regular heart rate readings to know your normal bpm readings to draw precise comparisons since every human has a slightly different resting heart rate. If the oximeter returns an abnormally high heart rate, stay calm and contact your doctor immediately.

For oxygen saturation, the number should ideally be over 95%. If it starts to dip below 93%, perform regular SPO2 checks and see a doctor if it continues to fall further down.

What do you mean by Best laptops for students?

Best laptops for students as they generally don’t need a costly laptop with state-of-the-art processors and graphics cards or sizeable hard drive storage capacities, or lots of RAM.

Quality and battery life are the two important and essential qualities to consider when purchasing a laptop for students of all ages.

However, there are hundreds of options to choose from, and going through them one by one is as difficult as helping others do their math homework.

What are the tips for choosing and buying a laptop?

• Make it compact enough to take to school or university, yet versatile enough to run the demanding applications.
• A laptop is the best tool to do a job, although tablets, pads, and mobile phones have come way in upcoming years.
• It is comfortable and works better with a laptop. So what type of laptop should we buy?
• There are laptops of all sizes, features, and prices, making choosing a suitable notebook difficult. That is why we can take into account what our needs are.

Quick tips

• If we are in a hurry to buy laptops, these are the essential things to consider when choosing:
• Displays from 12.5 to 14 inches offer a balance between usability and portability.
• Larger laptop screens are fine if we don’t travel a lot with the laptop, and smaller models are ideal for children, like tablets, for example.
• We can find the following data and specifications: Core i3 processor, 3 to 4 GB of RAM, and 1 TB of storage.
• More than seven and eight hours of battery life is ideal if we use the laptop on the go.
• You can have a 2-in-1 laptop if we want to use the computer as a tablet. Otherwise, a computer with a standard lid may be the best option.
• Chromebooks are suitable for kids or some chores.
• Windows laptops or Windows Macbooks offer a lot of functionality; which platform to use is a decision of personal taste.

Features to consider

• Size. If portability is required, we should choose a laptop with a smaller screen: from 12.5 or 14 inches and weighing less than 1 to 2 kilograms.
• Screen quality. A screen with high image quality is essential since we will use it for long periods, and we want it to be very comfortable for the eyes.
• Many laptops have touchscreens, which means they’re shiny.
• Glossy screens can reflect light, which can also be annoying.
• We should consider a non-touchscreen if that’s an issue.
• The resolution is also essential; we recommend a 1920 × 1080 (Full HD) to see all the applications correctly and consider the viewing angles.
• IPS displays have more comprehensive tips for better viewing comfort.
• Keyboard quality. For long hours typing on a keyboard, we should think about looking for a comfortable keyboard.
• We recommend you for looking a full keyboard with space for the arrow keys, which respond well to keystrokes.
• The backlighting helps us to type more easily in places with little light.
• Processor (CPU). Most newer laptops come with Intel Core processors (i3, i5, and i7).
• These processors offer the best performances when it comes to multitasking use and working with video.
• Cheaper laptops often carry Intel Core i3 processors that are usually perfect for student use.
• The Core i7s are for more demanding use; they tend to heat the laptop’s base more and limit the battery life.
• RAM. At least 4GB of RAM is required. More RAM allows us to use more applications at the same time, faster to load data such as to edit photos or videos.
• Storage. The best option for a laptop hard drive is to be a solid state drive (SSD) since the rest of the new and available hard drives are usually larger, slower, and noisier.
• SSD hard drives offer less capacity, much faster but are much more expensive.
