Ledemite: The Story of Blood Gas Analyzer

Firstly, what is blood gas analysis?

As the name suggests, blood gas refers to the dissolved O2 (oxygen) and CO2 (carbon dioxide) gases in the blood.

Blood gas analysis refers to measuring parameters such as partial pressure of oxygen (pO2), partial pressure of carbon dioxide (pCO2), and blood pH in the blood, and then analyzing and determining the ventilation and air exchange function of the lungs, the type and severity of respiratory failure, and various types of acid-base imbalances.

Why do we need to do blood gas analysis?

Blood gas analyzers play a crucial role in emergency treatment, respiratory failure, neonatal asphyxia, and other disease rescue and monitoring processes.

Blood gas analysis can evaluate the respiratory function and acid-base balance of the human body.

Enable medical staff to understand the patient's respiratory condition, lung function, and kidney function, and determine whether the patient has respiratory failure, internal environment disorders, and other conditions.

Blood gas analysis is the basis for providing oxygen or assisted respiration, and is used in ICUTesting methods.

On the other hand, patients with heart failure, kidney failure, severe diabetes, severe infection, and alcoholism will have acid-base imbalance in their bodies. Blood gas analysis is an important detection method.

In summary, blood gas analysis is an important monitoring measure for monitoring the condition, guiding treatment, and predicting prognosis.

With the development of emergency technology and intensive care medicine, as well as the popularization of blood gas analysis technology, blood gas analyzers are increasingly being used in hospital emergency departments, respiratory departments, pediatrics, obstetrics and gynecology, anesthesia departments, and other departments.

Today we will talk about the story of blood gas analyzer.

　　The birth of blood gas analyzer

When it comes to the world's first blood gas analyzer, it is inevitable to mention Radiometer.

In 1952, a severe outbreak of poliomyelitis occurred in Europe, causing many children to die from its complications - respiratory failure. At that time, this infectious diseaseIt is no less than the current AIDS or SARS, and the mortality rate is very high.

Due to the lack of satisfactory respirators, clinical doctors could only use their hands to press the rubber bag for ventilation, and the ward was immediately crowded with medical students constantly squeezing the rubber bag day and night. This has enabled some patients to escape from the critical stage of illness. But in order to figure out when to start ventilation, when to stop ventilation, and how much ventilation should be given to the patient, it is necessary to know the partial pressure of carbon dioxide in the blood. But at that time, the detection technology required up to two weeks to measure blood pH and carbon dioxide partial pressure, which posed great difficulties for timely diagnosis and correct treatment of patients.

Professor Poul Astrup, the head of the Chemistry Laboratory at the Danish Infectious Disease Hospital, has discovered through research that special electrodes can be used to measure pH and convert it to determine the partial pressure of carbon dioxide in the blood. This greatly improves the detection speed of blood pH and partial pressure of carbon dioxide. At this critical moment of life and death, Raydu Corporation, which was engaged in wireless technology at the time, stepped forward and collaborated with Professor Astrup to develop a pH analyzer, the Astrup Apparatus E50101, which was launched in 1954, saving the lives of thousands of patients.

By 1959, the first analyzer for detecting pH, pO2, and pCO2 was launched, and hospitals began measuring these parameters to diagnose and save patients' lives. For over half a century since then, Leidu has been committed to the mission of providing standardized blood gas analysis solutions for the correct diagnosis and treatment of critically ill patients, focusing on the field of critical illness detection with a focus on blood gas analysis. From then on, Leidu was closely integrated with blood gas analysis. And Professor Astrup is also revered by later generations as the father of blood and qi.

Introduction to Radiometer

Radiometer is now one of the major providers of critical care testing equipment and related services. The company was founded in 1935 and is headquartered in Copenhagen, Denmark. It has approximately 1700 employees and is distributed around the world. Its products are sold toMore than 100 countries and regions, and Denmark's Radu is also a member of Danaher Group, one of the Fortune 500 companies in the United States.

Since 1970, Danish Leidu products have entered the Chinese market. In 2005, Leidu China Branch was officially established, with its headquarters located in Shanghai and offices in Beijing and Guangzhou.

More than 60 years ago, in the face of a terrible infectious disease, Professor Poul Astrup and Raydu company stepped forward and developedBlood gas analyzer. With the rapid development of science and technology, the performance of blood gas analyzers has also been continuously improved. Over the past few decades, blood gas analysis technology has played a crucial role in critical care and monitoring, saving countless lives.

Leidu Company has always adhered to the concept of "life first, no matter what the future holds", and regards "assisting medical staff in making effective diagnostic decisions" as the common goal and mission of all employees of the company. It is this focus and passion that have enabled it to continuously advance the development of critical diagnosis solutions, innovate and improve products and solutions, and ultimately establish its position in related fieldsThe status.
