A. displays a normal breath and how information can be extracted from breaths in general. We define volume inhaled (TVi) as the amount of air breathed in on a breath. Tidal volume exhaled (TVe) is the amount of air exhaled. Positive end expiratory pressure (PEEP) is the minimum pressure setting for a ventilator. B. shows a series of breaths that occur due to a suctioning procedure. C. shows a breath stacking event, where a patient breathes in significantly more air than they exhale. D. shows a double trigger, which is two breaths that occur in rapid succession.
