Diagnostics and surgery

Gases are employed in healthcare for a variety of applications based on their properties. Among its many applications are the development of medical gases used for diagnosis in the field of surgery.

Medical gases for diagnostics and calibration

Medical gases play an important role in healthcare outside of the therapeutic applications. Medical carbon dioxide is an efficient insufflation gas that finds wide use in minimally invasive surgeries. Gas mixtures are also used to test and maintain the reliability and accuracy of a variety of medical devices and diagnostic equipment.

Diagnostics

Minimally invasive surgeries

Medical carbon dioxide is an efficient insufflations gas that finds wide use in minimally invasive surgeries. The gas is used in laparoscopy, arthroscopy, endoscopy, and cryotherapy. The gas helps to inflate the body cavities and stabilize them, so that surgeons have better visibility and access during surgery.

In temperatures below -76°C, carbon dioxide is used in cryotherapy or as a local analgesic. Using this technique, body cells are destroyed by the process of crystallization. 

Carbon dioxide

MRI

An MRI is a medical imaging technique used in radiology to obtain images of the anatomy and physiological processes of the body. Primarily used to detect tumors and abnormal tissue, MRI scanners use liquid Helium to cool the large magnet that maintains the extremely low temperatures necessary for the scanner to function properly.

Helium, a chemically inert gas, plays a fundamental role in a large number of sectors and applications, including MRI scanners.

Special gases

Surgery

Anesthesia

Anesthesia is a practice used to prevent pain during a painful surgery or procedure by administering medication through a vein or by inhalation.

Anesthetic gases, also known as inhaled anesthetics, are administered as primary therapy for preoperative sedation and adjunctive anesthesia maintenance to intravenous (IV) anesthetic agents in the perioperative setting.1 

Inhaled anesthetics enjoy regular use in the clinical setting due to chemical properties that allow the rapid introduction of an agent into arterial blood via the pulmonary circulation.
