1. Normal Breathing:

- The primary method of oxygen uptake is through normal breathing, where air is inhaled through the nose or mouth and reaches the lungs.

- The lungs contain tiny air sacs called alveoli, which are responsible for gas exchange.

- Oxygen from the inhaled air diffuses across the alveoli into the bloodstream.

2. Oxygen Mask:

- Oxygen masks are used to provide supplemental oxygen directly to the respiratory system.

- They come in different types and can be fitted over the nose or cover both the nose and mouth.

3. Supplemental Oxygen Tanks:

- Oxygen tanks contain compressed oxygen that can be delivered to individuals who require additional oxygen support.

- They can be used at home or while traveling.

4. Oxygen Concentrators:

- Oxygen concentrators are devices that extract oxygen from the ambient air and deliver it to the user.

- They operate electrically and are often used for long-term oxygen therapy at home.

5. Hyperbaric Oxygen Therapy:

- Hyperbaric oxygen therapy involves breathing pure oxygen in a pressurized chamber, which increases the amount of dissolved oxygen in the body's tissues and fluids.
