These documents explain key concepts in mechanical ventilation, beginning with the I:E ratio, which compares inspiratory to expiratory time and is typically maintained within a specific range, altered by adjusting factors like flow rate and tidal volume. It is shown how changing these variables affects the I:E ratio. The text then describes various flow waveforms, such as square, accelerating, decelerating, and sine, outlining their characteristics and potential benefits for gas distribution. Finally, the concept of a sigh breath is discussed, noting its historical use and current recommendations for specific situations like before and after procedures or when using small tidal volumes
