A suction catheter is a medical device used to clear mucus and other secretions from a patient's airway. It is typically a thin, flexible tube that connects to a suction machine, allowing healthcare providers to remove blockages that can hinder breathing. Suction catheters are commonly used in hospitals, especially in patients with respiratory issues or those who are unable to clear their own airways. These catheters come in various sizes and types, designed for different patients and situations. They can be inserted through the mouth or nose, depending on the patient's condition. Proper use of a suction catheter is essential to ensure patient safety and comfort while maintaining clear airways.
