Medical Device: A nasal cannula is a medical device used for delivering supplemental oxygen to patients who have difficulty breathing or require higher oxygen levels.
Flexible Tubes: It consists of two small, flexible tubes that are inserted into the patient's nostrils. These tubes are typically made of plastic and are lightweight.
Oxygen Flow: The nasal cannula is connected to an oxygen source, such as an oxygen tank or concentrator. It delivers a controlled flow of oxygen directly to the patient's nasal passages.
Comfortable: Nasal cannulas are generally well-tolerated by patients and are considered more comfortable than some other oxygen delivery methods like masks.
Mobility: Patients using nasal cannulas can move around more easily as they are not tethered to a fixed oxygen source. This enhances their mobility and quality of life.
