Suction machines are medical devices used to remove obstructions such as mucus, blood, or other secretions from a patient’s airway or surgical site. They are vital in emergency rooms, operating theaters, and home healthcare settings for patients with respiratory conditions. By providing efficient and continuous negative pressure, suction machines help maintain a clear airway, preventing aspiration and improving breathing. Their applications are crucial in managing conditions like chronic obstructive pulmonary disease (COPD), pneumonia, and during surgeries.
