Tracheostomy Suctioning: the nurse's role, start to finish
Written and reviewed by Dana Whitfield, RN, MSN · 4 min read · Updated September 2026
Short answer
Tracheostomy suctioning clears secretions from the airway using a sterile catheter, inserted without suction, applied for no longer than ten seconds on withdrawal. The patient is hyperoxygenated before and after the pass. It is done only when secretions are audible, visible, or the patient shows signs of airway obstruction, not on a fixed schedule.
What the procedure achieves
A tracheostomy bypasses the nose and upper airway's warming, filtering and humidifying function, so secretions thicken and accumulate faster than they would through a natural airway. Suctioning clears the tube and trachea of secretions the patient cannot cough out effectively, maintaining a patent airway and adequate gas exchange.
It is not a routine, clock-driven task. The indication is clinical: audible or visible secretions, a rise in peak airway pressures on a ventilated patient, oxygen desaturation, restlessness, or a visibly increased work of breathing. Suctioning a patient who doesn't need it irritates the tracheal mucosa and raises infection risk for no benefit.
Pre-procedure nursing responsibilities
Assess the indication before touching the catheter — auscultate, check oxygen saturation, and look at the patient's work of breathing. Explain the procedure to the patient even if they cannot speak; suctioning is uncomfortable and briefer if the patient isn't fighting it.
Gather sterile supplies before starting: the technique is sterile throughout, not clean. Hyperoxygenate the patient, typically with 100% oxygen for 30 to 60 seconds before the pass, to build a reserve against the desaturation suctioning itself will cause.
Equipment and positioning
Use a sterile suction catheter sized appropriately to the tracheostomy tube, sterile gloves, and wall or portable suction set to an appropriate negative pressure per your unit's protocol, generally lower for pediatric patients than adults. Position the patient semi-Fowler's if tolerated, which improves lung expansion and makes the airway easier to access.
Insert the catheter without applying suction — suction only on withdrawal, and withdraw with a gentle twisting motion. Limit each pass to no more than ten seconds from insertion to withdrawal; longer passes deprive the patient of oxygen and increase mucosal trauma.
Complications and early signs
Hypoxia is the most immediate risk, since suctioning removes oxygen along with secretions — watch the saturation monitor throughout and stop early if it drops sharply. Bradycardia can follow vagal stimulation from the catheter, particularly in infants and children, so monitor heart rate during the pass, not only after.
Mucosal trauma and bleeding follow repeated or overly forceful passes; blood-tinged secretions after a single pass warrant a gentler technique, not necessarily an emergency, but persistent bleeding needs provider notification. Accidental decannulation is a distinct risk during any manipulation near the tube — always stabilize the tube with your non-dominant hand.
Post-procedure care
Hyperoxygenate again after the pass to help the patient recover the oxygen reserve used during suctioning, and reassess breath sounds, saturation and work of breathing to confirm the airway is clearer. Allow rest between passes if more than one is needed — do not suction back-to-back without letting saturation recover.
Document the amount, color and consistency of secretions, the patient's tolerance, and any complications. A change in secretion character, particularly new purulence or a sudden increase in volume, is worth noting on its own since it can be an early sign of respiratory infection.
What to teach before discharge
Patients and caregivers managing a tracheostomy at home need to suction using clean technique rather than sterile, since the home environment doesn't carry the same infection risk profile as a hospital unit — but the timing principle stays the same: no longer than ten seconds per pass, no suction on insertion.
Teach recognition of the same warning signs a nurse assesses for: increased work of breathing, thick or discolored secretions, fever, or bleeding, and when each warrants a call to the provider versus emergency care. Cover tube care, stoma care, and what to do if the tube dislodges, since caregiver confidence with an emergency recannulation matters as much as routine suctioning technique.
The next step on this is the same as on everything else here: answer questions and read the rationales. Our respiratory practice questions are the closest set to what this page covers.
Common questions
How long should each suction pass last?
No longer than ten seconds from insertion to withdrawal. Suction is applied only while withdrawing the catheter, never on the way in, to limit hypoxia and mucosal trauma.
Is tracheostomy suctioning a sterile or clean procedure?
In the hospital setting it is sterile — sterile gloves and a sterile catheter throughout. At home, caregivers are typically taught clean technique instead, since the infection risk profile is different outside a healthcare facility.
Why is the patient hyperoxygenated before suctioning?
Suctioning removes oxygen from the airway along with secretions, and the catheter itself briefly displaces air. Preoxygenating, usually with 100% oxygen for 30 to 60 seconds, builds a reserve so the patient tolerates the drop that suctioning causes.
What heart rate change should a nurse watch for during suctioning?
Bradycardia from vagal stimulation, particularly in infants and young children. Monitor heart rate continuously during the pass and stop if it drops significantly, not only after the catheter is withdrawn.
How often should a tracheostomy be suctioned?
As needed, based on clinical signs — audible or visible secretions, desaturation, increased work of breathing, or rising airway pressures on a ventilator — not on a fixed schedule. Suctioning a patient who shows no indication increases trauma and infection risk without benefit.
