Introduction

The proper management of oxygen and medical gases in hospitals and healthcare facilities is considered one of the most critical and essential support and treatment components. Any deficiency or lack of order in the functioning of this sector can lead to irreparable damage. In this text, we will explore the relationship between the management of gas consumption and thermal mass flowmeters in healthcare facilities.

Classification of Medical Gases

Two main groups encompass medical gases.

1. Inhalation Gases: Patients inhale these gases. Notable examples include oxygen (O2) for respiration and nitrous oxide (N2O) for anesthesia in operating rooms.
2. Non-Inhalation Gases: These gases operate medical equipment and aid in patient treatment. For example, carbon dioxide (CO2) facilitates laparoscopy, and compressed air (nitrogen) powers pneumatic devices. These gases are classified as non-inhalation gases.

Sources of Gas Supply

Medical facilities receive medical gases from various sources, employing two primary methods:

1. Central Source: Gases flow to consumers through an internal pipeline network.
2. Cylinders: Some medical gases are distributed via cylinders, either connected to a pipeline network or directly to consumers.

Methods of Oxygen Delivery

There are three different methods for oxygen delivery to hospitals and consumer companies: oxygen concentrators, liquid oxygen tanks, and oxygen delivery methods. These three methods have different physical and performance characteristics, as outlined in the table below:

The table above clearly illustrates that each oxygen delivery method and medical gas management approach possesses distinct characteristics and advantages. The choice of method depends on the specific requirements and conditions of the healthcare facility. Ultimately, the decision should be based on technical, economic, and practical considerations to ensure efficient gas consumption and patient safety.
