An oxygen cylinder is a critical medical device used to supply supplemental oxygen to patients with breathing difficulties. It is widely used in hospitals, ambulances, and home-care settings. To understand how it works and how to choose the right one, it’s important to know the oxygen cylinder parts and functions, the types of oxygen cylinder, and their common applications.

What Is an Oxygen Cylinder?
An oxygen cylinder is a storage container filled with compressed medical-grade oxygen. It delivers oxygen safely to patients who cannot maintain adequate oxygen levels on their own due to medical conditions such as COPD, asthma, pneumonia, or post-surgery recovery.
Oxygen Cylinder Parts and Functions
Understanding the main components helps ensure safe usage and proper maintenance. Below are the key hospital oxygen cylinder parts name along with their functions:
Cylinder Body – Made of steel or aluminum, it stores oxygen under high pressure.
Cylinder Valve – Controls the release of oxygen from the cylinder.
Pressure Regulator – Reduces high pressure inside the cylinder to a safe, usable level.
Flow Meter – Measures and controls the flow rate of oxygen delivered to the patient.
Humidifier Bottle – Adds moisture to oxygen to prevent dryness in airways.
Outlet Nozzle – Connects tubing or oxygen masks.
Protective Cap – Prevents damage to the valve during handling or transport.
Each of these oxygen cylinder parts and functions plays a vital role in delivering oxygen safely and efficiently.
