How is a D cylinder oxygen tank classified in terms of size?

1. Large tank

2. Medium tank

3. Portable tank

4. Fixed tank

The correct answer is: Portable tank

A D cylinder oxygen tank is classified as a portable tank because of its size and design, making it easy to carry and transport for emergency medical situations. These tanks typically hold a smaller volume of oxygen compared to larger tanks, which allows for easy maneuverability by EMS personnel during patient transport or in situations where space is limited. Portable tanks like the D cylinder are essential for providing oxygen at the scene of an emergency or during transport to a medical facility, ensuring that patients receive necessary oxygen therapy without the constraints of larger, more cumbersome tank options. The portability makes it an invaluable resource in pre-hospital care, where quick access to oxygen can be critical for patient outcomes. Larger tanks would generally remain stationary or fixed in a medical facility, while fixed tanks are typically installed in locations for permanent use and not meant to be moved frequently. Medium tanks, while also portable, are not the standard designation used for the D cylinder, which specifically emphasizes its size and practical use in emergency settings.
