It could help if you are going to in ill. Preparing a finger pulse oximeter is very necessary at home especially for old men. It can help you a lot.


Understanding the readings of finger pulse oximeter

The pulse oximeters usually show the values of blood oxygen saturation levels as a percentage, represented by SpO2. While the pulse rate is displayed as a number ranging between 60 and 100, which indicates a normal heartbeat.

Why you should need a finger pulse oximeter?

The pulse oximeters usually show the values of blood oxygen saturation levels as a percentage, represented by SpO2. While the pulse rate is displayed as a number ranging in between 60 and 100, which indicates a normal heart rate.


A SpO2 reading ranging between 95% to 100% is considered normal, while less than 95% indicates underlying medical conditions that need to be evaluated immediately. The lower blood oxygen saturation levels might indicate the following health issues which need medical attention at the earliest:

  • Breathing difficulties
  • Lung infection
  • Blocked airways
  • Poor blood circulation


How to Understanding Oxygen Saturation?

Oxygen saturation (SpO2) measures how much oxygen blood carries in comparison to its full capacity. In other words, it’s an estimation of how much oxygen the hemoglobin in your blood contains compared to how much it could contain. Pulse oximetry devices represent this measurement using a simple percentage. So if your red blood cells contain 96% oxygenated and 4% non-oxygenated hemoglobin, your SpO2 would be 95%.


However,  things get more complicated. It’s possible for your SpO2 to constantly change throughout the day, especially when you’re transitioning from low-energy to high-energy activities. However, as long as your SpO2 stays within a healthy range amidst these fluctuations, there’s no need for concern.


Changes in activity aren’t the only factors that affect oxygen saturation. There are several adverse conditions and diseases that can negatively affect SpO2, including asthma and chronic obstructive pulmonary disease (COPD). People afflicted by these health issues often have a lower SpO2 average, necessitating the use of supplemental oxygen and other treatment methods.

Normal Range of Oxygen Saturation

Normal pulse oximeter readings usually range from 95% to 100%. Values under 90% are considered low and indicate the need for supplemental oxygen. This condition is often referred to as hypoxemia, and its symptoms include severe shortness of breath, increased heart rate, and chest pain.

Oxygen Level of Measuring

Nowadays, there are many tools to measure and monitor SpO2 including finger pulse oximeters. These compact, okaymedical devices attach painlessly to the fingertip and send wavelengths of light through the finger to assess SpO2 and pulse rate. Under the guidance of their physicians, people with heart and breathing problems can use personal finger pulse oximeters to manage their conditions and assess the efficacy of treatment methods. Pulse oximetry can be a useful aid in decision-making, but is not a substitute for a clinical assessment, nor sufficient for diagnosis by itself. Arterial blood gas measurements, obtained by arterial puncture, remain the gold standard for the measurement of oxygen saturation.


A personal finger pulse oximeter is designed to be fast, durable, and portable. All you have to do is place it on any finger and wait a few seconds for it to measure your current SpO2 and heart rate. However, not all pulse oximeters deliver the same level of performance and versatility. Many other brands of finger pulse oximeters are unable to perform with accuracy on patients with low perfusion or dark skin pigmentation, and can’t stand up to repeated daily use. That’s why in-home caretakers and people suffering from respiratory problems count on clinically proven self-monitoring solutions from okaymeidcal.

Maintenance of finger pulse oximeter

  1. Replace the batteries in a timely manner when low voltage light is lighted.
  2. Clean surface of the fingertip oximeter before it is used in diagnosis for patients.
  3. Remove the batteries if the pulse oximeter is not operated for a long time.
  4. It better to store a pulse oximeter in -20℃~+55℃and ~93% humidity.
  5. Keep in a dry place. Pay attention to moisture may affect pulses oximeter lifespan and may cause damage.


How to clean a finger pulse oximeter

Cleaning the Fingertip Pulse Oximeter. Please use medical alcohol to clean the silicone touching the finger inside of the pulse oximeter with a soft cloth dampened with 70% isopropyl alcohol. Also, clean the being tested finger using alcohol before and after each use. Do not pour or spray liquids onto the pulse oximeter, and do not allow any liquid to enter any openings in the device. Allow the pulse oximeter to dry thoroughly before reuse.
