Over the course of several hours a respiratory therapist has detected an increase in
PTA of a mechanically ventilated patient. The patient's Plateau pressure Has remained
stable. What May cause this increase?
Give this one a try later!
Increase of airway secretions
The maneuver used to measure plateau pressure is
Give this one a try later!
Inspiratory hold
, When both pressure and volume wave forms are affected by changes in lung
characteristics which variable is being controlled
Give this one a try later!
Time
Calculate the static effective compliance during the delivery of a ventilator breath
with 650 mL with a pressure plateau of 28 cm H2O and PEEP of 0.

23 mL/cmH2O
SCL= vt / Pplt-PEEP
What is the trans respiratory pressure if the ventilator is set at a volume of 500 mL with
a flow of 60 L/min and the patient's lung complaint is 0.75 L CM H2O and airway
resistance is 6 cm H2O L/Sec seconds
Give this one a try later!
6.7 cm H20
During volume control ventilation which wave form remains unchanged with changes
in the patient's lung characteristics
