During suctioning, how long should suction be applied during any one entry of the catheter?

Suction should be applied for a maximum of 10 seconds during any one entry of the catheter. This duration is critical because it helps to minimize the risk of hypoxia and mucosal trauma that can occur with prolonged suctioning. During suctioning, the patient's airway is temporarily deprived of oxygen as air flow is restricted; therefore, limiting suction time to 10 seconds helps ensure that the patient's oxygen levels are maintained and reduces discomfort.

It's important to balance the effectiveness of clearing secretions with the need to avoid complications. This guideline is widely accepted in clinical practice settings and is based on research that prioritizes patient safety and promotes optimal respiratory function. Keeping suctioning within this time frame allows for effective removal of secretions while minimizing the risk of adverse effects to the airway and the overall health of the patient.
