Nasal Cannula

Nasal cannulas are small, lightweight tubes that help people with breathing problems. They deliver supplemental oxygen, making it easier to breathe. This simple device is a lifeline for many with chronic lung diseases like COPD or emphysema.

These tubes send oxygen directly into the nostrils. This can greatly improve blood oxygen levels. It helps manage symptoms, increases mobility, and improves life quality for those who use them.

Let’s dive into how nasal cannulas have changed oxygen therapy and respiratory care. We’ll look at their design, function, and the latest tech advancements. The nasal cannula is a key tool for supporting breathing needs around the world.

What is a Nasal Cannula?

A nasal cannula is a medical device that helps people breathe better. It’s made of a soft, flexible tube that splits into two prongs. These prongs go into the nostrils.

The device is connected to an oxygen source. This could be an oxygen tank or concentrator. It makes sure the patient gets a steady flow of oxygen.

The main parts of a nasal cannula are:

Nasal cannulas are used in many places like hospitals and home care. They help people with long-term breathing problems. They also help those recovering from illnesses or surgery.

How Does a Nasal Cannula Work?

A nasal cannula is a simple yet effective device that delivers supplemental oxygen to patients who require it. It has a lightweight, flexible tube that splits into two prongs. These prongs are placed in the nostrils.

The nasal cannula is connected to an oxygen source, such as an oxygen concentrator. This source provides a steady flow of oxygen to the patient.

Oxygen Flow Rate and Delivery

The oxygen flow rate through a nasal cannula can be adjusted to meet the patient’s specific needs. Typical flow rates range from 1 to 6 liters per minute (LPM). Higher flow rates provide more oxygen to the patient.

The table below shows common oxygen flow rates and their corresponding oxygen concentration levels:

The oxygen delivered through the nasal cannula mixes with the patient’s inhaled air. This increases the overall oxygen concentration in the lungs. It helps improve oxygen saturation levels in the blood, which is essential for maintaining proper body function.
