Top 10 Commonly Confused Words in Mechanical Ventilation

Top 10 Commonly Confused Words in Mechanical Ventilation 1. Tidal Volume vs. Minute Volume Tidal volume refers to the amount of air delivered with each breath, while minute volume is the total amount of air delivered in a minute. Understanding the difference is crucial, as incorrect settings can lead to inadequate ventilation or excessive pressure on the lungs. 2. Peak Inspiratory Pressure vs. Plateau Pressure Peak inspiratory pressure is the highest pressure reached during inhalation, while plateau pressure is the pressure maintained at the end of inhalation. Monitoring both is vital to ensure the lungs are not being overdistended, which can cause injury. 3. FiO2 vs. PEEP FiO2, or fraction of inspired oxygen, is the concentration of oxygen delivered, while PEEP, or positive end-expiratory pressure, is the pressure maintained in the airways at the end of exhalation. Balancing both is essential to optimize oxygenation and prevent lung collapse. 4. Pressure Support vs. Pressure Control Pressure support provides additional pressure during inhalation, while pressure control delivers a set pressure throughout the breath. Understanding when to use each mode is crucial for patient comfort and synchrony with the ventilator. 5. Sensitivity vs. Specificity
