Mechanical ventilation can cause various complications, including physiological effects and equipment failures. Many adverse events are under-reported, highlighting the need for careful patient management and communication.

Area of Science:

  • Critical Care Medicine
  • Pulmonology
  • Biomedical Engineering

Background:

  • Mechanical ventilation is a life-saving intervention but is associated with numerous adverse effects.
  • The frequency and causal attribution of these complications are often underestimated and under-reported in medical literature.

Purpose of the Study:

  • To comprehensively review the spectrum of adverse effects and complications associated with mechanical ventilation.
  • To highlight the under-reporting of these events and the multifactorial nature of their occurrence.

Main Methods:

  • Review of existing medical literature on mechanical ventilation complications.
  • Categorization of complications into physiological effects, equipment-related issues, and medical events.
  • Analysis of contributing factors, including ventilator use, host defenses, and human error.

Main Results:

  • Positive-pressure ventilation can lead to decreased cardiac output, respiratory alkalosis, increased intracranial pressure, gastric distension, and impaired organ function.
  • Equipment malfunctions (e.g., cycling failure, alarm issues, improper gas conditioning) are significant concerns.
  • Severe medical complications include pneumothorax, bronchopleural fistula, and nosocomial pneumonia, influenced by both the ventilator and host factors.

Conclusions:

  • Mechanical ventilation is linked to a wide array of under-reported complications, extending beyond direct ventilator effects.
  • Effective management requires addressing physiological impacts, equipment reliability, and preventing medical complications.
  • Minimizing adverse outcomes necessitates improved understanding, communication, and vigilance among healthcare providers.
