Contec Finger vs Oxiline Pulse 9 Pro. What Do I Choose?

Contec Finger vs Oxiline Pulse 9 Pro

In the arterial blood of a healthy person, the saturation index ranges from 96 to 100%.

If you examine the venous blood, then the value will normally be about 75%.

This is due to the fact that the blood gives off some oxygen to the cells of the body, and then returns back to the lungs.

If in arterial blood saturation decreases to 94%, this indicates an acute or chronic course of dangerous lung diseases.

With a decrease in hemoglobin saturation with oxygen to 92-93% and below, this indicates a dangerous state of hypoxia and the need for urgent hospitalization.

To get accurate saturation results, ONLY high-quality pulse oximeters will help you with these aspects.

I am not a supporter of expensive purchases.

Even though I am a medical worker. However, everything you need can really be bought at good prices. Moreover, by examining your health, you can prevent diseases that’s why let’s look together at Contec 50DL and Oxiline Pulse 9 Pro Pulse Oximeters and choose the best model for a good price.

How Do Contec Finger vs Oxiline Pulse 9 Pro Work?

For diagnosis, the patient only needs to place one of the fingers in the photoelectric sensor, and the measured hemoglobin oxygen saturation value will immediately be shown on the display.

These 2 Pulse Oximeters consist of several parts:

  • A diode that emits light.
  • A sensor sensitive to light – during the measurement is located on the back of the finger.
  • Monitor on which the result will be displayed.

To determine the level of saturation, the diode emits light that completely shines through the finger.

The principle of operation of the device is the ability of saturated and unsaturated hemoglobin to absorb light.

The sensor, which is located on the back side, captures the residual amount of light and analyzes this data. The amount of saturated hemoglobin associated with oxygen is displayed on the screen.

My Feedback: How Accurate Are the Contec Oximeter vs Oxiline Pulse 9 Pro Work?

Both of these 2 pulse oximeters are very compact devices that is easy to take with you on any trip and put in your work bag.

I take it with me just in my pocket when I go on a long run. It is no secret that it is very important to monitor the pulse and its difference before and after the training.

When comparing these 2 Pulse Oximeters Contec 50 Dl and Oxiline Pulse Oximeter, I would choose Oxiline Pulse 9 Pro. Although, I think both of them are reliable.

It shows a saturation of 99% what is really accurate, and it has more features such as: Smart alarm when the measurements are low, plethysmograph waveform– this indicator helps you visualize your perfusion Index in real time, a Perfusion Index (PI)- it is the ratio of pulsing blood to non-pulsing blood

The pulse oximeter was bought in 2020, that is, it has been serving for more than 2 years – so far it has not broken, it does not junk.

What I like about Contec Pulse Oximeter is that there is a useful feature of the pulse oximeter is automatic shutdown. After 8 seconds, after the measurement, it will turn itself off. This is useful in order not to waste energy.

In general, the device is excellent for home use too. And in the period of such diseases, this is one of the few remedies that will give you peace of mind for confidence.

Anyway, from all Oxiline Pulse Oximeters I would suggest choosing Oxiline Pulse X Pro because it is an improved pulse oximeter from all the versions and has better features. The screen of the device is large and clearer in order to read the readings well.


What Happens When Oxygen Becomes Low?

Shortness of breath, chest pain, confusion, headache and rapid heartbeat, cyanosis of the nasolabial triangle and fingertips – such unpleasant symptoms can appear if the level of oxygen in the blood begins to drop.

 Do I need to Know My Saturation?

As a rule, no. The exception is if you have diseased lungs, and you are watching the dynamics of the disease.

Is Contec an Omron Brand?

Omron Contec Pulse Oximeter is a medical monitoring and diagnostic device for non-invasive measurement of capillary blood oxygen saturation (pulse oximetry).

What To Do if The Saturation Is 80?

If the saturation in the position of the patient on the stomach is below 90%, tracheal intubation is indicated. Once every two hours, you need to deprive the patient of oxygen. If blood saturation falls below 80%, tracheal intubation is indicated.
