A) End expiration: At rest, intrapleural pressure must remain slightly negative (here it is shown as -5 mmHg) as i) the lung is elastic and has a tendency to collapse or shrink, and ii) the fluid lining the alveolar surfaces generates surface tension that works to collapse the lung.
The clinician sets a pressure high, pressure low, and a time ateach level (time high and time low). Ventilation occurs during the releasefrom pressure high to pressure low. The time low is typically 0.2â0.8 sec-onds in restrictive lung disease and 0.8â1.5 seconds in obstructive lung dis-ease. It is probably most prudent to start at 0.8 and titrate to meetindividual patient requirements.
