Tracheostomy Care and Respiratory Complications Management

1. Hyperoxygenate: Provide the patient with $100\% \text{ } FiO_2$ for one minute prior to suctioning.
2. Insertion: Advance the catheter until resistance is met or the patient coughs.
3. Withdrawal: Withdraw the catheter with intermittent suctioning and a rotating motion.
4. Duration and Frequency: Each suction pass must not exceed $15$ seconds, and there should be a maximum of three attempts per session.

Warning: Complications Improper tracheostomy management can lead to severe complications, including air embolism, aspiration, subcutaneous emphysema (air leaking into subcutaneous tissue), laryngeal damage, tube dislodgement, and accidental decannulation.

Aspiration and Pneumonia

Aspiration occurs when foreign material is inhaled into the lungs. This is a significant risk factor for developing aspiration pneumonia, a condition where the inhaled material acts as a reservoir for bacteria.

Risk Factors and Prevention

Patients at risk for aspiration often exhibit swallowing difficulties, such as coughing during intake or "pocketing" food in the cheeks, which may indicate weakened muscles. To prevent aspiration, nursing interventions include:

• Elevating the head of the bed to $>30^{\circ}$.
• Verifying the placement of G-tubes before feedings.
• Transitioning patients to thickened liquids if they struggle with thin liquids.

Pneumonia is an inflammation of the lung parenchyma caused by bacteria, viruses, or fungi. Symptoms often include a sudden onset of chills, fever, pleuritic chest pain, and the production of purulent sputum. Influenza is a common viral precursor; antivirals like oseltamivir are most effective when initiated within $24\text{--}48$ hours of symptom onset.

Pleural Disorders and Chest Tubes

Pleural effusion is the accumulation of fluid in the pleural space, often secondary to heart failure, malignancy, or infection. Diagnosis is typically achieved through chest X-ray, CT scans, or thoracentesis.

Pneumothorax

A major complication of thoracentesis is pneumothorax, which is the presence of air in the pleural space. This can be spontaneous or traumatic (e.g., from an accident). Clinical manifestations include dyspnea, tachycardia, asymmetrical chest movement, and potentially tracheal deviation in severe cases.

Chest Tube Management

Chest tubes are inserted into the pleural space to drain air, blood, or fluid to facilitate lung expansion. Nurses must monitor the following:

• Tidaling: The expected fluctuation of fluid in the water-seal chamber with respiration. The cessation of tidaling may indicate the lung has re-expanded or there is an obstruction (like a kink).
• Continuous Bubbling: In the water-seal chamber, continuous bubbling indicates an air leak in the system. Note that intermittent bubbling during coughing or sneezing is expected when draining air.

Emergency Protocol: Accidental Removal If a chest tube is accidentally removed from the chest, cover the site immediately with a sterile gauze dressing and tape it on three sides. This creates a one-way valve that allows air to escape during exhalation but prevents it from entering during inhalation.

Atelectasis and Respiratory Support

Atelectasis is the collapse or closure of the alveoli. It is common in postoperative settings and can be acute or chronic. Symptoms include increased respiratory effort, hypoxemia (low blood oxygen), dyspnea (shortness of breath), and decreased breath sounds or crackles upon auscultation.

Management Strategies

To prevent and manage atelectasis, clinicians utilize:

• Incentive Spirometry: Encouraging deep breathing to expand the lungs.
• Frequent Turning and Early Mobilization: To prevent stasis and promote lung expansion.
• Positive End-Expiratory Pressure (PEEP): Providing pressure during expiration to keep alveoli open and treat hypoxia.

Mechanical Ventilation and Respiratory Failure

Mechanical ventilation is used to support patients experiencing respiratory failure, which is the inability to adequately ventilate or oxygenate.

Ventilator Modes

• PEEP: Delivers preset pressure during expiration to treat persistent hypoxia.
• Pressure Support: Helps keep alveoli from collapsing and decreases the work of breathing.
• CPAP (Continuous Positive Airway Pressure): Provides continuous pressure during spontaneous, patient-driven breaths.

Nursing Care and Complications

Critical care for ventilated patients includes performing oral care with chlorhexidine every 2 hours to prevent Ventilator-Associated Pneumonia (VAP). Medications such as sedatives (e.g., Versed) and analgesics (e.g., Fentanyl) are used to prevent the patient from "fighting" the ventilator.

Note on Paralytics: Neuromuscular blocking agents (paralytics) only paralyze muscles; they provide no sedation or pain relief and must always be used in conjunction with sedation and analgesia.

Weaning and Complications

When weaning a patient from a ventilator, clinicians must monitor for distress. Signs that a patient is not tolerating weaning include:

• Respiratory rate $> 30$ breaths/min.
• $SpO_2 < 90\%$.
• Heart rate or blood pressure changes $> 20\%$.
• Increased restlessness, anxiety, or decreased level of consciousness.

Complications of mechanical ventilation include barotrauma (pressure-related injury), volutrauma (volume-related injury), oxygen toxicity, and hemodynamic compromise due to increased thoracic pressure decreasing venous return.
