One of the indicators of the course of COVID-19 and other diseases is saturation – the level of oxygen in a person’s blood.
Usually, Elderly people are isolated at home and do not have the opportunity to receive timely medical advice and monitor their condition in case of illness or the appearance of the first symptoms.
Each of them needs a pulse oximeter, which makes it possible even at home to receive information about the state of the lungs and quickly respond to changes.
In a Hurry? My Fast Answer is
Unfortunately none of them made it to my top #1 Oximeter list.
Let me tell you about the Wellue O2Ring – it’s like the superhero of pulse oximeters, seriously!
One of the coolest things about it is that it doesn’t just clip onto your finger like your average oximeter.
Nope, it’s a smart ring that you wear on your finger, making it super comfortable and convenient. You won’t even feel like you’re wearing anything special, yet it’s working its magic behind the scenes.
What sets the Wellue O2Ring apart from the pack is its continuous monitoring feature.
Most pulse oximeters just give you a snapshot of your oxygen saturation and heart rate, but this bad boy keeps tabs on your levels around the clock.
Whether you’re chilling on the couch, out for a jog, or catching those Z’s, it’s right there with you, providing real-time data.

How Fast can Saturation decrease of Eldery people?
Saturation is a variable indicator that can fluctuate throughout the day.
Prolonged stay indoors, physical activity (walking, climbing stairs) for eldery people lead to a slight temporary decrease in saturation.
However, in the absence of concomitant pathologies of the respiratory tract, the indicator independently stabilizes after rest.
In the presence of inflammation, the development of coronavirus infection, self-normalization of saturation is impossible. The progression of the disease leads to a gradual decrease in the index.
The rate of decrease in saturation depends on the severity of the disease. So, with coronavirus infection, saturation in the elderly decreases by 1-2% every day.
A more rapid decrease in oxygen in the blood indicates the development of complications of the inflammatory process and requires continuous monitoring of the patient.
Summing up, it should be noted that oxygen saturation in the blood is an indicator that requires periodic monitoring in all older people.
Changing the values helps to suspect inflammation even before the appearance of a clinical picture.
Thus, it is possible to react in time and conduct an additional examination to establish the exact cause of the decrease in saturation and prescribe the appropriate treatment.
Help in monitoring the level of saturation Of Elderly
It is difficult to independently monitor blood oxygen saturation in an elderly person, and it is dangerous to lose sight of critical changes.
But with a right pulse oximeter this approach will help in time to identify the occurrence of inflammatory processes, pathologies, and changes in the functioning of the respiratory system.
Learn more about pulse oximetry of Eldery
Pulse oximetry is a method of measuring the level of oxygen in the blood in a non-invasive way (without damaging the skin).
For this, pulse oximeters are used. Everyone who used such a device must have seen a red or green light that “shines through” a finger.
This light is absorbed by hemoglobin. Moreover, the intensity of absorption depends on the “load” of hemoglobin with oxygen.
The pulse oximeter determines how much light has been absorbed and calculates the saturation level.
Best pulse oximeter for elderly, seniors?
1.Wellue O2 Ring
The Wellue O2 Ring is the best variant for senior people.
It is a modern silicone ring that works as an overnight sleep tracking and as a pulse oximeter and sleeping tracker with an integrated SpO2 sensor to measure oxygen saturation and a heart rate sensor.
The tracker ring is an additional device for monitoring the health of seniors with heart and lung diseases, sleep apnea attacks.
This sleeping tracker and a sleeping tracker has a built-in vibration alert system for changes in blood oxygen levels and heart rate for user feedback.
And also O2 Ring uses Bluetooth Low Energy to connect to the phone.
The tracker ring can be worn throughout the day, but will be most beneficial at night, especially for seniors who experience episodes of obstructive sleep apnea, the main manifestation of which is snoring.
In obstructive sleep apnea, the level of oxygen saturation in the blood drops and hypoxia occurs.
The O2 Ring responds to changes in oxygen levels with a vibration that wakes the wearer up to change their position to a more comfortable position or to breathe and fall asleep again.
The device remembers a sleeping report of you.(How long you fell asleep, how often you woke up, captures movements, and determines the quality of rest, the phases of deep and light sleep).
A useful feature is a smart alarm clock.
It will turn on not at a given minute, but in the phase of light sleep. Medicine claims that awakening in this phase facilitates adaptation to the active period. A Senior who wakes up in a light phase will be cheerful.

Another product that is in service with hospitals and clinics.
It is inexpensive, so seniors often buy it for themselves. It features a universal fastening – it is made in the form of a soft clothespin, so it will not slip off the fingers, regardless of their thickness.
This allows even small children to measure oxygen levels. The two parts of this clothespin are connected to each other with a very tight spring.
The main working surfaces that are in direct contact with the patient’s skin are covered with a layer of soft rubber. It will not allow the device to slide off.
The sensor is highly accurate, the processor processes the information instantly, so the measurement result is known in just a few seconds. The equipment can be used even in low light conditions. The control button is easy to touch, the LCD display has a built-in backlight.
How reliable are pulse oximeter readings?
The accuracy and reliability of measurements depends not only on the model of the pulse oximeter, but also on a huge variety of other factors.
The amount of external light can lead to a significant error.
Different pulse oximeters show different accuracy when measuring in different patients. Hair on the measured area of the body, tattoos, dirt, even skin pigmentation – all affect the quality of the measurements taken.
To find out with what accuracy your device measures, it is advisable to take a blood test in the laboratory, and then compare the results of laboratory tests and your meter.
If there is no possibility or desire, then one should resort to the methods of mathematical statistics. 5-10 measurements should be taken in a row, on different fingers.
The arithmetic mean can be taken as a reliable result. However, such complexity is not always necessary.
The accuracy of any pulse oximeter is enough to determine the approximate level of oxygen saturation in the blood, which can be used to make a decision to see a doctor.
Remember that pulse oximetry at home is only a rough picture of what is really happening.
Instructions of How to use a pulse oximeter for Eldery people?
Despite the fact that pulse oximeters use a rather unusual optical measurement technology, the device itself does not require special skills to use.
The application algorithm is always in the instructions for each individual device.
- Check the charge. If your pulse oximeter is powered by rechargeable batteries or batteries, it is necessary to provide timely replacement (recharging) of the batteries, as the measurement error increases when the charge decreases.
- Measurements are recommended to be made in a dark or shaded place to prevent sunlight from reaching the photosensitive sensors. In some cases, the hand with the pulse oximeter can be hidden in a pocket or covered with a thick cloth during the measurement.
- Before measurement, it is recommended to firmly fix the sensor on the body, avoiding displacement during the entire process. It is desirable that the skin at the point of contact with the emitters is clean, since excess dirt can introduce an error into the result. If a finger pulse oximeter is used, nail polish should be removed.
- During the measurement, it is recommended not to move so as not to change the position of the sensors relative to the body. There should also be even and calm breathing.
My Final Thoughts
A home pulse oximeter is a great way to keep your own health or that of an elderly relative under control.
For people suffering from hypoxia, undergoing rehabilitation after pulmonary diseases, suffering from asthma or COVID-19, buying a pulse oximeter in a home first aid kit will be completely justified.
You or your elderly relatives will not have to sigh heavily, checking “feels like” breathing is bad or good.
Clear indications, even with a slight error, will tell you whether it is worth sounding the alarm or you can calm down and continue rehabilitation or treatment at home.
FAQs
What is a normal saturation for a 70 year old senior?
Normal Oxygen saturation levels is usually between 95 to 100 percent.
Is 94 a good oxygen level?
Good oxygen level is between 96% and 99% and a good heart rate is between 50 and 90 beats per minute (bpm).
How to increase saturation Of Elderly people?
There are many ways to increase the saturation level in the elderly.
The most obvious of these is to let the patient breathe in an oxygen mixture.
But this method will only work if there is a problem with the respiratory system. If low saturation develops against the background of anemia, treatment will be aimed at eliminating this condition.
To do this, the doctor may prescribe vitamins, trace elements or other medications. Seniors can also raise saturation with the help of physical exercises.
However, not all types of physical activity are suitable for this, but only some of them. For them to be effective, the exercises must be performed under the supervision of an instructor.
