Oxygen Tank 5lbs refers to a smaller, portable oxygen cylinder that holds compressed oxygen gas. The "5lbs" indicates the weight of the cylinder when it is fully filled with oxygen. These tanks are lightweight and designed for mobility, making them suitable for home oxygen therapy, emergency medical services, or short-term use in various healthcare settings. Despite their smaller size, they provide a sufficient supply of oxygen and are typically used with oxygen regulators and masks or nasal cannulas for patient administration. The 5lbs tank is ideal for individuals who need oxygen therapy but require a more compact, easily transportable solution.
