Orders After Intubation and Initiation of Mechanical Ventilation
Confirm ETT Placement:
CXR Portable: Obtain a portable chest X-ray immediately to confirm the correct placement of the endotracheal tube.
Auscultation: Listen for bilateral breath sounds to ensure proper tube placement.
Capnography: Use end-tidal CO2 monitoring to confirm the presence of CO2, indicating correct tracheal placement.
Monitoring:
Continuous SpO2 Monitoring: Use pulse oximetry to continuously monitor oxygen saturation.
ABG: Perform an arterial blood gas analysis to assess oxygenation, ventilation, and acid-base status.
Sedation and Analgesia:
Sedation: Administer medications such as midazolam or propofol to keep the patient comfortable and prevent agitation.
Analgesia: Provide pain control with agents like fentanyl or morphine if necessary.
Ventilator Settings:
Mode: Select the appropriate ventilator mode (e.g., AC-PCV, SIMV, PSV).
Tidal Volume (Vt): Set tidal volume based on the patient’s ideal body weight (6-8 mL/kg).
Respiratory Rate (RR): Adjust the rate to achieve desired minute ventilation and blood gas targets.
FiO2: Set initial FiO2 to 100% and then titrate down based on SpO2 and ABG results.
PEEP: Adjust positive end-expiratory pressure (PEEP) to improve oxygenation and prevent alveolar collapse.
Additional Orders:
Suctioning: Perform endotracheal suctioning as needed to clear secretions.
Head of Bed Elevation: Keep the head of the bed elevated at 30-45 degrees to reduce the risk of aspiration.
DVT Prophylaxis: Administer prophylactic anticoagulation (e.g., heparin) to prevent deep vein thrombosis.
GI Prophylaxis: Use medications like proton pump inhibitors (e.g., pantoprazole) to prevent stress ulcers.
Investigations and Monitoring:
Septic Workup: Continue with blood cultures, urine cultures, and sputum cultures as part of the workup for underlying infection.
Daily Labs: Monitor electrolytes, complete blood count, renal function, and liver enzymes.
Daily Chest X-rays: Obtain chest X-rays daily or as needed to monitor for complications such as pneumothorax or pneumonia.
Detailed Understanding of Ventilator Settings
1. Modes of Ventilation:
Assist-Control Ventilation (ACV): Provides full support with preset tidal volume or pressure for each breath. Useful in patients who cannot initiate adequate breaths.
Synchronized Intermittent Mandatory Ventilation (SIMV): Delivers a set number of mandatory breaths, allowing the patient to breathe spontaneously between them.
Pressure Support Ventilation (PSV): Provides support during spontaneous breaths by delivering a preset pressure, reducing the work of breathing.
2. Tidal Volume (Vt):
Normal Range: 6-8 mL/kg of ideal body weight.
Purpose: Ensures adequate ventilation while minimizing the risk of barotrauma and volutrauma.
3. Respiratory Rate (RR):
Normal Range: 12-20 breaths per minute.
Adjustment: Based on ABG results to achieve appropriate CO2 elimination.
4. Fraction of Inspired Oxygen (FiO2):
Initial Setting: 100%, then titrate down based on oxygenation status.
Goal: Maintain SpO2 > 92% and PaO2 > 60 mmHg while minimizing oxygen toxicity.
5. Positive End-Expiratory Pressure (PEEP):
Normal Range: 5-10 cm H2O.
Purpose: Prevents alveolar collapse, improves oxygenation, and enhances functional residual capacity.
6. Inspiratory to Expiratory Ratio (I: E ratio Ratio):
Normal Ratio: 1:2 or 1:3.
Purpose: Ensures adequate exhalation time to prevent air trapping and auto-PEEP.
7. Pressure Control and Pressure Support:
Pressure Control (Pi): Set inspiratory pressure in pressure-controlled modes.
Pressure Support (PS): Additional pressure provided during spontaneous breaths in modes like PSV.
Example of Initial Ventilator Settings for an Adult Patient:
Assist-Control Pressure-Controlled Ventilation (AC-PCV):
Mode: AC-PCV
RR: 20 breaths/min
Pi: 8 cm H2O
Ti: 0.85 seconds
Flow Trigger: 3 L/min
FiO2: 0.3 (30%)
PEEP: 5 cm H2O
Spontaneous Mode with Pressure Support Ventilation (PSV):
PS: 12 cm H2O
E Sensitivity: 18%
Flow Trigger: 0.5 L/min
FiO2: 0.21 (21%)
CPAP: 5 cm H2O
Ongoing Management
Regular Monitoring:
ABG Analysis: Repeat ABG to monitor for adequate ventilation and oxygenation.
Ventilator Parameters: Adjust settings based on clinical status, ABG results, and chest X-ray findings.
Daily Assessment:
Weaning Readiness: Evaluate daily for readiness to wean from the ventilator by assessing respiratory effort, ABG, and overall clinical improvement.
Addressing Complications:
Ventilator-Associated Pneumonia (VAP): Implement VAP prevention strategies such as regular oral care, subglottic suctioning, and minimizing sedation.
Barotrauma: Monitor for signs of barotrauma (e.g., pneumothorax) and adjust ventilator settings to reduce risk.
By understanding these settings and management steps, healthcare providers can effectively support patients requiring mechanical ventilation and address their complex needs comprehensively.
