Breathing tubes are medical devices used to help patients breathe when they cannot do so effectively on their own. These tubes can be inserted into the airway to provide oxygen directly to the lungs. They are commonly used in emergency situations, during surgeries, or for patients with respiratory conditions. There are different types of breathing tubes, including endotracheal tubes and tracheostomy tubes. Endotracheal tubes are typically used for short-term ventilation, while tracheostomy tubes are designed for long-term use. Both types are essential in critical care settings to ensure that patients receive adequate oxygen.
