An oxygen mask is a medical device used to deliver oxygen directly to a patient’s nose and mouth during oxygen therapy. It is commonly used in hospitals, clinics, ambulances, and home care settings for patients experiencing breathing difficulties or low oxygen levels. The mask is made from soft, medical-grade plastic that fits comfortably over the face and is connected to an oxygen source such as an oxygen cylinder or concentrator through flexible tubing. Many oxygen masks include an adjustable elastic strap and a nose clip to ensure a secure and comfortable fit. Designed to provide a higher concentration of oxygen than nasal cannulas, it helps improve breathing efficiency and oxygen intake. Lightweight, hygienic, and easy to use, an oxygen mask is an essential accessory for effective respiratory care and emergency medical support.
