Respiratory Distress, Tracheostomy Care and Chest Tubes

In this lesson you will
  • Differentiate early versus late signs of hypoxia and identify clinical indicators of severe respiratory distress.
  • Describe safe tracheostomy suctioning, airway maintenance, and emergency dislodgement interventions within practical nursing scope.
  • Monitor chest tube drainage systems correctly and execute immediate nursing actions for dislodgement, disconnection, or system complications.

Recognizing Respiratory Distress and Hypoxia

Prompt identification of oxygenation problems is essential to safe nursing care. Early signs of hypoxia include restlessness, anxiety, irritability, tachycardia, and tachypnea. When oxygen levels drop, the brain and heart react first to compensate for the shortage. If hypoxia progresses without effective intervention, late signs of severe hypoxia emerge, including cyanosis, bradycardia, marked lethargy, and a decreased level of consciousness. The practical nurse immediately alerts the RN and activates the emergency response system for sudden respiratory depression, cyanosis, or tracheal deviation.

Increased work of breathing indicates that a client is struggling to move air. Key visual signs include retractions, nasal flaring, and the active use of sternocleidomastoid accessory muscles. Clients may also experience orthopnea, which is difficulty breathing while lying supine that is relieved by sitting upright. An ominous data finding is paradoxical abdominal breathing, where the abdomen pulls inward during inhalation rather than expanding outward; this indicates diaphragmatic fatigue and impending respiratory failure.

The practical nurse collects focused respiratory data, including rate, rhythm, depth, oxygen saturation, and lung sounds. An oxygen saturation below 90% generally indicates hypoxemia, although some clients have a prescribed target of 88% to 92%. The practical nurse promptly reports a new low reading or one below the prescribed range to the RN. When caring for a client in acute respiratory distress, the practical nurse helps the client sit upright in a position that eases breathing, such as high-Fowler or tripod position, and promptly alerts the RN.

Exam tip. Do not wait for cyanosis to recognize hypoxia on exam questions. Cyanosis is a late sign of severe hypoxia. Watch for early behavioral changes like restlessness, anxiety, or irritability paired with an increased pulse and breathing rate.

Common mistakes

  • Clamping chest tube drainage systems routinely or stripping the tubing, which can cause tension pneumothorax or dangerous high negative intrathoracic pressures.
  • Applying continuous suction while inserting a suction catheter into a tracheostomy tube rather than applying suction intermittently only during withdrawal.
  • Attempting blind reinsertion of an accidentally dislodged immature tracheostomy tube instead of calling for help and supporting ventilation.
  • Assuming digital clubbing is an expected characteristic finding of chronic obstructive pulmonary disease rather than reporting it as a potential sign of lung cancer or bronchiectasis.

Key points

  • Recognize early hypoxia by identifying restlessness, anxiety, irritability, tachycardia, and tachypnea, and report late signs such as cyanosis, bradycardia, and lethargy immediately.
  • Assist clients in respiratory distress into a high-Fowler or tripod position, collect focused respiratory data, and report low oxygen saturations to the RN.
  • Support asthma care by reinforcing spacer use, mouth rinsing after inhaled steroids, and treating a silent chest or red-zone peak flow as emergencies.
  • Manage COPD and pneumonia by maintaining prescribed oxygen ranges (88% to 92% in hypercapnia), reinforcing pursed-lip breathing, and encouraging incentive spirometry ten times hourly while awake.
  • Maintain tracheostomy safety by keeping spare tubes and an obturator at the bedside, using sterile technique for open suctioning, limiting passes to 10-15 seconds, and maintaining cuff pressures between 20 and 25 cm H2O.
  • Respond correctly to dislodged tracheostomies: reinsert a mature tube with an obturator only if trained and permitted, but avoid blind reinsertion of an immature tube and support ventilation.
  • Keep chest drainage systems upright and below chest level, avoid routine clamping or milking, submerge disconnected tubes in 2 cm of sterile water, and dress dislodged chest insertion sites with a three-sided occlusive dressing.
