What is the correct method for suctioning?

The correct method for suctioning involves first ensuring that the equipment is ready and functioning properly. Position the patient appropriately, usually at a 30 to 45-degree angle. Insert the suction catheter gently into the airway without applying suction, then withdraw it while applying suction for no longer than 10-15 seconds, allowing the patient to rest in between attempts. Finally, assess the patient's response and repeat if necessary, ensuring to maintain proper hygiene and follow any specific guidelines relevant to the patient's condition.
