A pulse oximeter is a medical device that measures the level of oxygen in the blood (the so-called saturation indicator).
Regular monitoring of saturation is very important in the presence of pulmonary diseases – asthma, bronchitis, pneumonia.
Due to the rapidly growing demand for pulse oximeters in the past two years due to the spread of coronavirus infection, the number of low-quality, counterfeit, including counterfeit products has also increased on the market.

The quality of pulse oximeters must be documented in accordance with the provisions of current legislation.
Pulse oximeters can be classified according to several main features:
- By scope – household and professional;
- At the place of measurement – shoulder or wrist;
- According to the method of operation – stationary and portable;
- By measurement range;
- Measurable indicators, etc.
Why Do Pulse Oximeters Need Permit Documents?
Registration and obtaining permit documents of pulse oximeters as well as other medical devices is a state procedure that regulates the release of high-quality, safe and effective medical devices to the market.
As a result of the registration of a medical device, you receive a registration certificate for a medical device
Which Documents Do Pulse Oximeters get?
Pulse oximeters for their legal sale in many countries must have the following types of permits as part of the shipping documentation: (Of course it depends on the country)
- Registration certificate
- Certificate of conformity
Registration certificate
All medical devices put into circulation must be registered with the government in accordance with the requirements of the government.
The registration procedure is quite long and laborious, it is carried out once.
The final document – RC, is issued indefinitely with positive results of the verification. In the future, it does not require re-registration.
To obtain a license, you need to have a complete set of documents for manufactured products.
Certificate of conformity
The technical regulations establish requirements in the field of electromagnetic compatibility.
During the tests, the level of electromagnetic interference generation is evaluated when measuring oxygen in the blood with a pulse oximeter, as well as the stability of the device when exposed to electromagnetic interference generated by other electrical devices.
A certificate is issued both for mass-produced goods and for a batch.
According to the current legislation, all manufacturers of medical devices are required to develop and use a quality management system based on their standards in production(depending on the country).
This certificate allows you to more effectively organize risk management work based on their analysis, documenting processes, optimizing production, reducing scrap, increasing productivity, etc.
It is noteworthy that the implementation of this certificate according to ISO 13485 is mandatory, and the certification of the management system is carried out on a voluntary basis.
What is FDA Approval?
The job of the US Food and Drug Administration (FDA) is to tell us what food, pills, or medical devices are safe to consume.
And while many people think that everything that is allowed and approved by the FDA undergoes rigorous testing, in reality this is not always the case.
There is a big difference between pills or medical devices that have been cleared by the FDA and approved by the FDA.
And with more and more electronics going through the hands of the FDA today, it’s important to understand the difference.

|
FDA approved means that “the benefits of a product outweigh its known risks when used appropriately.” To obtain such approval, manufacturers must apply on the PMA (pre-market authorization) form and attach the results of clinical testing. In deciding whether to approve the use of a product, the FDA must decide whether its benefits outweigh its risks. Usually, the FDA tends to approve the use of a high-risk product if there are significant benefits from its use – as, for example, in the case of an artificial heart valve that can save someone’s life. |
Class I and II medical devices typically receive an “FDA cleared” when a manufacturer can demonstrate that its product is “substantially equivalent to another similar and legally advertised” device that has already been approved or cleared by the FDA. |
Just because the FDA has approved or cleared a device does not mean that it is safe.
This is why you may see class action lawsuit ads looking for people or relatives of people who have been seriously injured or even killed by using FDA-approved products.
Such defective products can end up having a significant impact on health, despite their permission or approval.
It is important to understand that the FDA does not develop products that it evaluates and approves.
It does not conduct its own tests either – it simply reviews the results of tests conducted by independent laboratories and clinics to determine whether a device, pill or dietary supplement is as safe and effective as the manufacturer claims…
