Pressure controlled ventilation delivers a preset inspiratory pressure over a predetermined time. T/F
True
Which of the following is pressure controlled ventilation have greater advantages than volume controlled ventilation?
BMI 36
________ augments patient breaths with a set amount of pressure support.
PSV
Which is an advantage of PCV?
Which ventilator mode employs a set tidal volume with variable peak inspiratory pressures based on changes in lung compliance or airway resistance
During PCV, inspiratory flow typically uses a decelerating pattern. T/F
T
Which ventilator mode reverses the I:E ratio and requires a sedated and paralyzed patient?
Inverse ratio ventilation
Select the two parameters that are VARIABLE in PCV:
These are advantages of PCV > VCV. Select all that apply:
Alveolar pressure above atmospheric pressure is defined as:
PEEP
A disadvantage of pressure controlled ventilation includes:
Which modes allows support of a patient’s spontaneous breaths, but has a backup “mode” if the patient stops initiating breaths?
PSVPro
Which ventilator mode relies entirely on spontaneous breaths by the patient, who must have an intact respiratory drive?
PSV
Plateau pressures greater than 35 cm H2O are associated with:
Barotrauma
In PCV, which situation will INCREASE the patient’s tidal volume?
Release of pneumoperitoneum
During volume controlled ventilation, select the three variables that are FIXED.
During pressure-controlled ventilation, which will decrease tidal volume?
Pneumoperitoneum
Which ventilator mode is useful for weaning patients, delivers a set tidal volume and respiratory rate, but allows the patient to breathe spontaneously between machine breaths?
SIMV
In __________ , increased airway resistance or decreased lung compliance reduces tidal volume.
PCV
