Pulse Oximeters




Pulse Oximeters Online at Best Prices in India

A pulse oximeter is the most accurate way to measure blood oxygen levels at home, and it can provide additional information (pulse rate) for COVID patients who are confirmed or suspect. At home, an oximeter reading can provide information about a person's blood oxygen levels and pulse, but one should pay closer attention to symptoms that may indicate an emergency.

What is a Pulse Oximeter?

A pulse oximeter is a simple, compact, portable, low-cost, and non-invasive device used to monitor the amount of oxygen carried in the body.

If you have Asthma, Anaemia, Pneumonia, Lung Cancer, Cardiovascular Diseases, Congestive Heart Failure (CHF), or Chronic Obstructive Pulmonary Disease(COPD), you must have your oxygen levels checked on a regular basis.


A pulse oximeter's primary function is to record the pulse rates and oxygen saturation levels in the human body. It is a simple and inexpensive machine that provides a thorough examination of your cardiovascular and respiratory systems. It is task-oriented and painless, and you can use it whenever you want and carry it in your pocket while commuting.

What is pulse oximetry and why do you need one?

The amount of oxygen in the blood is measured using pulse oximetry.

Pulse oximetry is a non-invasive method of measuring an individual's oxygen saturation (SO2). It is a simple, painless test that determines how well oxygen is delivered to parts of your body far from your heart, such as your arms and legs.


A probe, which resembles a clip, is placed on a body part such as a finger or ear lobe. Using light, the probe determines the amount of oxygen in the blood. This information assists a healthcare provider in determining whether a patient requires additional oxygen.


To survive, every system and organ in the body requires oxygen. Cells begin to malfunction and eventually die in the absence of oxygen. Cell death can result in severe symptoms and, in the worst-case scenario, organ failure.

Situations that Oxygen saturation can drop

Pulse oximetry can be used to determine whether or not there is enough oxygen in the blood. This information is useful in a variety of situations.

A decrease in oxygen saturation can be caused by a variety of factors, including:

  • choking
  • suffocation
  • infections, such as pneumonia
  • drowning
  • diseases, such as lung cancer, lung infections, and emphysema
  • inhaling poisonous chemicals
  • heart failure or a history of heart attacks
  • allergic reactions
  • general anesthesia
  • sleep apnea

Usage of Pulse Oximeter

During or after surgery or sedation procedures, a pulse oximeter may be used.
  • To determine how well lung medicines are working
  • To assess a person's ability to handle increased activity levels
  • To determine whether a ventilator is required to assist with breathing, or how well it is working
  • To see if a person has moments when their breathing stops while sleeping (sleep apnea)

Pulse oximetry is also used to assess a person's health if they have a condition that causes low blood oxygen levels, such as:

  • Heart failure
  • Heart attack
  • Chronic obstructive pulmonary disease (COPD)
  • Lung cancer
  • Anemia
  • Pneumonia
  • Asthma
  • Pulse oximeters are useful for people who suffer from conditions that reduce oxygen saturation. A sleep specialist, for example, might recommend a pulse oximeter to monitor a person's night time oxygen saturation level if they have suspected sleep apnea or severe snoring.
  • Pulse oximetry can also provide data on the effectiveness of breathing interventions such as oxygen therapy and ventilators.
  • • Some doctors use pulse oximetry to evaluate the safety of physical activity in patients with cardiovascular or respiratory problems, or they may advise a patient to wear a pulse oximeter while exercising. Pulse oximetry may also be used as part of a stress test by a doctor.
  • Pulse oximeters are also used in some hospitals for the most vulnerable patients. Infants in neonatal intensive care units may wear pulse oximeters, which can alert staff to a drop in oxygen saturation.

In a nutshell, the benefits of pulse oximetry are as follows:

  • monitoring oxygen saturation over time 
  • alerting to dangerously low oxygen levels, especially in newborns
  • providing peace of mind to people with chronic respiratory or cardiovascular conditions 
  • determining the need for supplemental oxygen 
  • monitoring oxygen saturation levels in anaesthetized patients
  • identifying potentially hazardous side effects in people taking drugs that affect breathing or oxygen saturation

How does Pulse Oximeter Work?

The device can be attached to a finger, a wrist, a foot, or any other area where blood flow can be measured.

By shining a light through a relatively transparent area of the skin, a pulse oximeter measures oxygen levels. The light travels through the skin to a detector on the opposite side.

When a pulse oximeter is attached to a finger, one side of the clip shines the light and the other detects it.

The amount of light absorbed by the blood indicates the saturation level of oxygen. A pulse oximeter does not directly measure oxygen saturation, but rather estimates it using a complex equation and other data.

What is a normal reading on an oximeter?

Your oxygen saturation level is a measurement of the amount of oxygen in your blood. When using a blood gas, it may be referred to as a PaO2 and when using a pulse oximeter, it may be referred to as an O2 sat (SpO2). These guidelines will assist you in determining what your results may imply:

A healthy person's blood oxygen saturation, or SpO2, should be between 95% and 100%. When your blood oxygen saturation, or SpO2, falls below 90%, the amount of oxygen going to your brain and other vital organs suffers. Low oxygen levels can cause confusion and lethargy in people. Levels below 80% are equally dangerous as the risk of organ damage increases.

However, in the case of COPD or other lung diseases, these ranges may not be applicable. Your doctor will tell you what is normal for your particular condition. It's not uncommon for people with severe COPD to keep their pulse oxygen levels (SpO2) between 88 and 92 percent.

What is a normal reading on an oximeter?

SpO2  LevelIndicationHealthcare intervention
NormalMore than or equal to 95%No intervention needed
Hypoxic85% to 92%Assess for underlying respiratory disease and initiate oxygen therapy
Severely HypoxicLess than 85%Administer supplemental oxygen immediately.

Readings of pulse oximeter for Patients with COPD

SpO2  LevelIndicationHealthcare intervention
Normal88% to 92%Continue with respiratory assessment and monitoring
HypoxicLess than 88%initiate oxygen therapy

What level of oxygen is dangerous? And what can be the consequences

A low oxygen level of less than 88 percent can be harmful at any time. A blood oxygen level of less than 85% necessitates a visit to the hospital. Remember that an oxygen level of 80% or lower puts your vital organs in danger, so keep a blood oxygen level chart handy so you know what levels require immediate treatment.

Low Pulse rate consequences: Under normal conditions, a human's pulse rate ranges between 60 and 100 beats per minute (bpm). The pulse effectively monitors the rate of heart contraction and expansion. In fact, a pulse rate of less than 60bmp may result in:

  • Declining cardiovascular fitness
  • Heat ailments such as Bradycardia
  • Unexpected fainting
  • Loss of memory
  • Expected fainting

Low oxygen rate consequences: SpO2 levels of 95 percent or higher are considered normal by medical scientists and experts. Readings less than 92 percent, on the other hand, indicate insufficient or inadequate blood oxygen saturation. A low oxygen saturation level in the blood can result in:

Adverse health conditions include: 

  • shortness of breath 
  • chest pain 
  • increased heart rate

How to use pulse oximeters correctly at home?

Follow the steps below to learn how to use a pulse Oximeter in minutes:

  • Carefully attach the device to your fingertip through the wide opening in the middle. 
  • The panel over the oximeter will display your current pulse rate as well as the amount of oxygen in your body.
  • Finally, the labels mentioned above will assist your physician in determining the oxygen saturation levels in your body.

What to Consider while Purchasing a Pulse Oximeter?

  • Accuracy: Choose a device with a margin of error of no more than 2% plus or minus.
  • Battery Life: The time it takes to charge the batteries. The batteries in the pulse oximeters we chose have a battery life of 30 to 40 hours, which can last for years.
  • Display: Is the unit's display easy to read in all lighting conditions? Look for features such as back-lit displays and rotating displays. Another significant difference is whether or not the device has a pulse rate waveform, which can aid in monitoring the pulse rate over time.
  • Alarms: Does the pulse oximeter device notify you when the battery is low, when you are low on oxygen, or when you have a low heartbeat?
  • Durability: Check to see what kind of warranty each pulse oximeter model comes with. This frequently refers to the device's durability.
  • Fit: Does the unit comfortably fit your finger? The majority of pulse oximeters range in size from 0.5 to 3 inches. The pulse oximeter should be snugly wrapped around your index finger. If your finger pulses out from the oximeter, it is too small. Measure your finger from the tip of your nail to the bottom of the pad or first line on the end of your finger before ordering a pulse oximeter online.
