Fortunately, tracheal pressure can be modified with ventilator
adjustments to improve speech. Perhaps the most
simple and successful set of ventilator adjustments is the
combination of prolonged inspiratory time and positive
end-expiratory pressure (PEEP).80,84 Prolonged inspiratory
time (or decreased inspiratory flow) increases the time that
speech can be produced during inspiration, and PEEP increases
the time that speech can be produced during ex-
