Oximeter Heart Rate Monitor (They are so called since they have two functions in the same device, or another name Digital Finger Pulse Oximeter. Are you looking for some good information?

Before buying an oximeter read this good information:

Precision: Without this quality, be expensive or cheap oximeter will not be more than a toy.

Durability: These devices are made of plastic and with use in constant movements if they are not well manufactured they will break easily.

Who is this Oximeter and Heart Rate Monitor for?

Although good information says that on the sales page that it is perfect for parents, respiratory care, medical rooms, nurses and athletes, use of the home to monitor the oxygen level in the blood and pulse rate. The truth is suitable for everyone (except babies and animals) given everyone needs to have good health.


  • Measure the pulse (heart rate) of the person (on the finger).
  • The use is really easy, only putting your index finger in the apparatus, after a few seconds
  • The level of your pulse is already out.
  • Measure the oxygen saturation in the blood.
  • From the same process mentioned above, % Spo2 or oxygen level in the blood also comes out.

An apparatus with correct use always gives good results. This also happens the use of How to use Oximeter and Heart Rate Monitor. Although its application seems simple but better follow the steps recommended by professionals. A pulse oximeter is a medical device that measures the heart rate and oxygen level in the blood, shown with the percentage of oxygen saturation.

Pulse oximeters work by shining light through the skin, and then through the blood vessels. These devices are usually used in medical consultations, although one can also do it at home without a prescription. High oxygen saturation – close to 100 percent (usually between 95-99%) – indicates that the person is well (only in that aspect, that the distribution of oxygen in the body is at a good level).

Good information:

  • Turn on the oximeter/heart rate monitor by pressing the power on button. The screen must activate at the same time.
  • Place any finger on the device by inserting it until it touches the bottom. It does not recommend using them
  • Thumb because they are thicker than the readings may be less accurate than those of the fingers.

Wait a while without moving much while oximeter/heart rate monitor signals. This may take 10 seconds or more, depending on the device and the conditions. Try to remain still during the measurement because the excess movement can affect the accuracy thus giving errors in the reading. Set to see your heart rate, usually indicated with a heart a stripe or also with continuous cyclic waveforms. The percentage of oxygen saturation is indicated by the letter “% SpO2”. Some brands ring at the rate of heart rate. Leave the sensor on for a continuous observation. When the signals on the screen remain more or less static or already vary little because those are your pulse number and the saturation of oxygen in the blood. When you remove your finger, the slide will usually turn off automatically. So are the values rated as regular? Look at this good information.

Some models of oximeter/pulsometer warn with sound if the values go beyond the control levels. That is, % Spo2 <90 o (PR) less than 50BPM or more than 120 BPM. If your numbers are out of the ordinary, you should seek medical attention immediately. The technology advances rapidly and with it, the functions of the equipment we use daily are also updated. That’s why today we want you to know the main functions that you must evaluate when buying or renewing a portable oximeter.

Accuracy: during clinical trials of the device’s technology it is important that the device guarantees 2% (more or less) of the actual SpO2 levels. The oximeter must have an accuracy of up to 70% oxygen saturation. This means that even when the patient’s arterial oxygen levels are not ideal, the device will continue to give an accurate reading.

Warning systems: there are 3 warning systems that you should keep in mind when choosing an oximeter:

  • Irregular heartbeat
  • Low SpO2

Low battery

Durability: the difference between duration and price could mean the difference between life and death in a series of different scenarios if constant monitoring of SpO2 levels is required. A quality pulse oximeter will be able to resist falling to the ground and should be waterproof to withstand falling into the water and also to protect it from moisture – a situation is known to cause inaccurate readings and/or device failure.

Maintenance: once calibrated, the pulse oximeters will work the same after two years as they did the first day of their opening. All these devices perform a start check of their circuits when they are turned on and will not execute a scan unless they pass these built-in tests.

Automatic activation: the ability to turn on automatically when a finger is inserted or in contact with the skin on the device may seem like a novelty or convenience feature. However, once again, this feature could mean the difference between life and death in some cases. Nellcor is a brand that meets this characteristic.

Visible screen: look for a pulse oximeter with a backlit screen. There are several backlight and font color combinations to choose from.

Use: define if the device will be for exclusive hospital use, emergency response, operating room, etc.

Finger oximeters: for the control of the eyelashes at their level, intended for patients, caregivers, and consumers. It is used for personal health and well-being, home care, hospital, and clinics.

  • Handheld devices with sensors: for continuous monitoring; ideal for the hospital, the ambulatory or the home.
  • Boards with sensors: for continuous monitoring; ideal for hospitals, medical facilities, home care and subacute environments.
  • Sensors: neonate, pediatric, adult; reusable, single-patient or disposable.


For the price and its functions, it is not bad to have one with it. Thus we will be more attentive to our health day by day. Health is the priority before other aspects of life. Well, through good information have good health for you and your families.
