How Ventilators Save Lives in ICU
*Introduction - When a person cannot breathe adequately on their own, mechanical ventilation becomes a lifeline. This life-saving medical intervention provides respiratory support using advanced machines known as ventilators. From intensive care units (ICUs) to operating rooms, mechanical ventilation is a critical tool for sustaining life during respiratory failure, surgery, or trauma. Over the past century, ventilators have evolved from simple negative-pressure devices like the “iron lung” to highly sophisticated microprocessor-driven machines. Today, they are equipped with advanced modes, real-time monitoring, and artificial intelligence features that allow precise, personalized care for patients. In this extended guide, we will dive deep into every aspect of mechanical ventilation, covering: • Definition and history • How ventilators work • Types and modes of ventilation • Common settings and monitoring techniques • Indications and patient selection • Risks and complicat...
