Saturimetro Oximeter: Non-Invasive Health Warning

The Saturimetro Oximeter, also known as a Pulse Oximeter, can monitor the oxygen levels in the blood (blood oxygen saturation) in real-time without the need for blood sampling using detectors or sensors. It is a small medical device used to measure indicators such as blood oxygen saturation, pulse rate, and perfusion index in the human body.

Working Principle of the Saturimetro Oximeter

Saturimetro Oximeter works based on the absorption spectrum characteristics of reduced hemoglobin and oxyhemoglobin in the red and near-red light regions, using the Lambert-Beer law to establish data processing empirical formulas. The device operates using photoelectric blood oxygen detection technology combined with volumetric pulse plethysmography. It uses two beams of light at different wavelengths (660 nm red light and 940 nm near-infrared light) that pass through a fingertip sensor to illuminate the human fingernail. The photodetector collects the measurement signals, which are then processed by electronic circuits and a microprocessor, with the results displayed on two LED groups.

Saturimetro Oximeter Measurement Indicators

The primary indicators measured by the Saturimetro Oximeter are blood oxygen saturation, pulse rate, and perfusion index.

Blood Oxygen Saturation

Blood oxygen saturation refers to the percentage of oxyhemoglobin (oxygen-bound hemoglobin) relative to the total hemoglobin capacity that can bind with oxygen in the blood. It reflects the concentration of oxygen in the blood and is an essential physiological parameter for the respiratory cycle.

Pulse Rate

Pulse rate indicates the frequency of arterial pulses, specifically the number of pulses per minute. Pulse rate can be influenced by factors such as age, gender, exercise, and emotions. Clinically, many diseases, particularly heart diseases, can cause changes in pulse rate, making it an important monitoring indicator for patients.

Perfusion Index

The perfusion index reflects the blood flow perfusion status, indicating the pulsatile blood flow. The greater the pulsatile blood flow, the higher the proportion of pulsatile component, and thus, the larger the PI value.

Saturimetro Oximeter Applicable Population

Individuals with cardiovascular diseases

Such as coronary heart disease, hypertension, hyperlipidemia, and cerebral thrombosis. Patients with these conditions might experience thickened blood accompanied by coronary artery atherosclerosis and narrowed blood vessels, leading to potential ischaemia and hypoxia. Using a Saturimetro Oximeter can help measure their blood oxygen levels and pulse changes, enabling timely treatment when fluctuations in blood oxygen occur.

Individuals with respiratory diseases

Such as asthma, bronchitis, chronic obstructive pulmonary disease (COPD), and pulmonary heart disease. Respiratory diseases can cause breathing difficulties and hypoxia, affecting vital organs like the heart and brain. A Saturimetro Oximeter can monitor their blood oxygen saturation, reducing the incidence of serious respiratory diseases.

Aging Population with Physiological Deterioration of Cardio-Pulmonary Function

People with physiological aging of the cardio-pulmonary organs may experience insufficient blood perfusion and consequent hypoxia. A Saturimetro Oximeter helps in timely monitoring of the perfusion index to prevent insufficient blood oxygen.

Types of Saturimetro Oximeters

Desktop Multi-Parameter Monitor

In hospitals, you often see monitors displaying various graphs and values next to patients. These multi-parameter monitors typically include a pulse oximeter, capable of measuring and displaying blood oxygen saturation, pulse rate, ECG, blood pressure, body temperature, and other information.

Handheld pulse oximeters are portable devices convenient for healthcare staff to carry while patrolling wards or during sudden changes in the patient's condition. They can also be temporarily installed by the bedside for continuous monitoring of blood oxygen saturation.

Wrist Pulse Oximeter

Suitable for hospitalized patients to wear, allowing healthcare providers to check patient information at any time. Patients can also view their readings in real-time and seek medical help promptly.

Fingertip Pulse Oximeter

Used for spot-checking (not continuous monitoring, measures specific moment values) and emphasizes compactness, making it suitable for daily household use as an integrated fingertip pulse oximeter.

Saturimetro Oximeter Selection Guide

Consumers are advised to choose a suitable saturimetro oximeter product based on factors like purpose, usage habits, and usage scenarios:

• For monitoring bedridden patients long-term, you can choose a desktop multi-parameter monitor with an integrated blood oxygen detection module;

  
  

• For home backup, the commonly used fingertip pulse oximeter for household scenarios is recommended;

  
  

• For elderly care, choose a wrist-worn oximeter with long-term monitoring and alarm functions;

  
  

• For sports enthusiasts, opt for a sports watch that combines blood pressure and blood oxygen monitoring functions.
