Complication of Mechanical Ventilation
Complication of Mechanical Ventilation
David Ray Velez, MD
Intubation/Endotracheal Tube Complications
- Local Trauma
- Endotracheal Tube Obstruction or Occlusion
- Esophageal Intubation
- Right- or Left-Mainstem Bronchus Intubation
- Aspiration
- Tracheal Stenosis or Necrosis
Patient-Ventilator Dyssychrony
- Inappropriate Timing and Delivery of a Mechanical Breath in Response to Patient Effort
- *See Patient-Ventilator Dyssychrony
Ventilator-Induced Lung Injury (VILI)
- Atelectrauma – Trauma from the Shear-Stress Created by Recruiting/Opening Atelectatic Alveoli
- Barotrauma – Trauma from High Inspiratory Pressure Causing Alveolar Over-Distention
- Volutrauma – Trauma from Increased Volume Causing Alveolar Over-Distention
- Biotrauma – Additional Injury Due to the Inflammatory Response to Mechanical Injury
- *See Ventilator-Induced Lung Injury (VILI)
Dynamic Hyperinflation (DHI)
- Definitions:
- Air Trapping (Air Stacking): Hyperinflation (Increased End-Expiratory Lung Volumes) Due to Incomplete Exhalation
- Auto PEEP (Intrinsic PEEP/PEEPi): Increased Positive End Expiratory Pressure from Hyperinflation
- *See Dynamic Hyperinflation (DHI)
Ventilator-Induced Diaphragmatic Dysfunction (VIDD)
- Diaphragm Muscle Atrophy and Contractile Dysfunction
- Caused by Oxidative Stress, Protein Imbalance, and Myotrauma
Ventilator-Associated Pneumonia (VAP)
- *See Ventilator-Associated Pneumonia (VAP)
Other Complications
- Secretion Retention
- Gastritis and Peptic Ulcer
- Oxygen Toxicity
- Increased Intrathoracic Pressure Causing Decreased Venous Return and Cardiac Output
