What is a blood oxygen meter? Uses and notes when using

Blood oxygen meter is a useful and necessary health care device of every family. So what is a blood oxygen meter and what is it used for? Let’s find out the article below with lassho.edu.vn to get the answer!

What is a blood oxygen meter?

Blood oxygen meter is a device used to measure oxygen saturation (SpO2) in blood vessels and heart rate to help users promptly detect abnormal phenomena in the body for quick treatment and avoidance. endanger health.

Structure

Each type of blood oxygen meter will have a different structure. However, all devices have a basic structure consisting of a display screen and a probe to measure the circuit .

Working principle

• The blood oxygen meter works on the basis of a spectrometer (chromatography) and a pulsometer (pulsation) mechanism .
• Usually SpO2 meter determines the readings through the fingertip thanks to photoelectric technology . When a fingertip is placed on the probe, the plastic on the top of the nail generates a luminescent light so that the plastic under the finger (which is the image detector) comes together to form the transducer.
• When the machine starts up, an electromagnetic pulse consisting of two beams of different wavelengths is generated from the plastic part of the nail through the finger to the image detector. The special feature of these two beams is the concentration at the clamping point at the fingertips.
• Next, the probe receives the signal and image from the imager. This information and images are processed through circuits and microprocessors to produce results displayed on the meter screen.​

What is a blood oxygen meter used for?

Each person’s body has 5 vital signs such as temperature, blood pressure, breathing rate, heart rate and blood oxygen level. A blood oxygen meter is used to measure blood oxygen levels and measure heart rate .

Therefore, this is a useful and really necessary product in monitoring health for every family and has a particularly important role in anesthesia and surgery cases , helping doctors accurately assess the condition. patients to come up with the most appropriate and effective solution.

Types of blood oxygen meters

Based on the structure and design characteristics, people divide the blood oxygen meter into:

– Portable blood oxygen meter: compact design, easy to carry with you, suitable for personal or family use. Portable blood oxygen meter is also divided into 2 types:

• The machine has a separate screen and probe, connected to each other through wires.
• The device has a screen and probe attached to each other into a block, almost like a clamp.

– Desktop blood oxygen meter: quite large size, suitable for use in professional environments such as clinics, hospitals, …

Some notes when using a blood oxygen meter

• Read the user manual carefully before use.
• When using the device, you should clean your fingers with a cotton or soft cloth soaked in alcohol to ensure the most accurate results.
• During the measurement, you need to sit still, not move.
• The device should not be used on one finger for more than 30 minutes.
• Absolutely do not use sharp objects to impact the machine.
• Do not use the device in potentially explosive atmospheres.
• Do not use batteries that do not conform to the specifications of the device to avoid damage to the device.
• When the device has a low battery signal, please replace the battery immediately, ensuring maximum normal operation of the device.
• Do not use the instrument immediately after moving from a cold to hot environment, to avoid affecting operability and accuracy.
• Do not use sharp objects to impact the device causing damage.
• In case you temporarily do not need to use it for a long time, please remove the battery from the device.
