What is a Pulse
A pulse oximeter is a non-invasive used to measure the oxygen saturation and heart rate of a person. In basic terms, it tells us how much oxygen is present in our blood. It is a small chip-like device put on a person’s finger to get oxygen saturation. In some cases, at the toe or an earlobe.
Why Should You Use
In the current
global pandemic, the rapidly evolving situation around the virus, it is good to
get a home treatment of COVID-19 when feasible; this will enable the doctor to
focus on the mass population who needs them urgently. Even the Central
government shared the guidelines to use Pulse Oximeter; this will assist them
in noticing whether they require hospitalization or not.
Common Cases that
Require an Oximeter
An oximeter is a
must-buy device for those who are facing regular breathlessness; the instrument
will let them know what amount of oxygen they are lagging with and further
should they consult or not.
The blood oxygen
level can be affected in several cases like chronic obstructive pulmonary
disease (COPD), asthma, COVID-19, pneumonia, lung cancer, anemia, heart attack
or heart failure, congenital heart defects.
suffering any of these should get a Pulse Oximeter at home.
How to use a pulse
- Doctors recommend taking a rest for 10-15 mins before checking oxygen level.
- Put oximeter in middle finger or index finger (on the nail side).
- Keep the hand still, do not shake the finger; this may lead to inappropriate measurement.
- Keep track of the measure, and finally note the highest result when the reading is stabilized.
- Identify each recording carefully.
- Start recording from baseline and record three times a day at the same time.
How to read a pulse
Once all the values
are noted, we must understand what the given values represent. If the reading
says 97%, 3% of blood cells have depleted oxygen values.
For a healthy human facing no breathlessness, pulse oximeter reading lies between 95-100%.
When the pulse
oximeter reading lies between 90-95%, the individual should consult a
The case can be
critical if the pulse oximeter reading is less than 90%; the patient must be
taken to a doctor. This is how to read oximeter:
Pulse Oximeter Readings
A Finger pulse oximeter is a helpful device, even though there are a few limitations of the reading it measures.

Factors that disturb readings of finger oximeter:
Lights in the surrounding:
While operating the device, it is necessary to cover the sensors of the
oximeter from the surrounding lights.
Skin pigmentation: Dark skins
absorb the light produced by oximeter than light skin, so it is generally
recommended to find a spot where there is bright pigmentation. Even the test
should not be conducted with hands dyed, and fingers nail polished.
Finger or hand
movement: It is an essential controllable factor, the test should be
conducted where the person could relax, and not much of an activity is
required. Oximeter values are sensitive to movement. Therefore you must look
for the best oximeter in your sight.
Low blood volume: The lack of
blood value prevents the sensors from reading the accur
Presence of Carbon Monoxide (CO): Carbon Monoxide in blood slightly affects the accuracy since the device faces difficulty distinguishing between Caron Monoxide and Oxygen.

Do we need a pulse
A pulse oximeter is
mean to measure oxygen saturation. It is a device that will give us the
reading, but in the current pandemic havoc wrecked worldwide with evolving
COVID-19, it is wise to suggest having an oximeter at home. If you are
breathless, you will get to know how urgently you need a doctor or if the
breathing suffocation is normal.
inaccuracy in pulse oximeter?
sometimes give inaccurate measurements due to a few factors like; the skin
color of the region where the device has to be set up. The low volume makes it
difficult for the Oximeter to measure the values. Carbon Monoxide in blood
makes it difficult for the Oximeter to get the deals since both cannot
differentiate between Carbon Monoxide and Oxygen.
What is the typical
value range for a pulse oximeter?
The average range
value of pulse oximeter varies between 95-100%.
Can oxygen levels
be correctly measured at home?
If one uses a
suitable oximeter, one could measure oxygen level with reasonable accuracy.
