Pressure controlled ventilation delivers a preset inspiratory pressure over a predetermined time. T/F

True

100

Which of the following is pressure controlled ventilation have greater advantages than volume controlled ventilation?

  • BMI 23
  • Knee surgery
  • BMI 36
  • Spontaneous ventilation

BMI 36


100

________ augments patient breaths with a set amount of pressure support.

  • PSV
  • PCV-VG
  • CMV
  • VCV

PSV

200

Which is an advantage of PCV?

  • It is dangerous for low compliance patients
  • Larger tidal volumes are delivered for a given inspiratory airway pressure
  • It is a “plug and play” ventilation mode
  • PCV allows for synchrony with a patient’s spontaneous breaths
  • Larger tidal volumes are delivered for a given inspiratory airway pressure
200

Which ventilator mode employs a set tidal volume with variable peak inspiratory pressures based on changes in lung compliance or airway resistance

  • Pressure support
  • Pressure control
  • Volume control
  • Airway pressure release ventilation
  • Volume control
200

During PCV, inspiratory flow typically uses a decelerating pattern. T/F

T

200

Which ventilator mode reverses the I:E ratio and requires a sedated and paralyzed patient?

  • Airway pressure release ventilation
  • Inverse ratio ventilation
  • Synchronized intermittent mandatory ventilation
  • Controlled mandatory ventilation

Inverse ratio ventilation

300

Select the two parameters that are VARIABLE in PCV:

  • PIP
  • Inspiratory Flow

  • Inspiratory time
  • Inspiratory Flow
  • Vt
300

These are advantages of PCV > VCV. Select all that apply:

  • Leak compensation
  • ARDS
  • Neonates
  • Cuffed ETT
  • Leak compensation
  • ARDS

300

Alveolar pressure above atmospheric pressure is defined as:

  • Peak Pressure
  • Positive end-expiratory pressure
  • Plateau pressure
  • Airway pressure

PEEP

300

A disadvantage of pressure controlled ventilation includes:

  • A decreased airway resistance leads to reduced tidal volume
  • Tidal volume is preset, disregarding peak inspiratory pressures
  • Decreased lung compliance reduces tidal volume
  • There is an increased risk for ventilator associated lung injury
  • Decreased lung compliance reduces tidal volume
400

Which modes allows support of a patient’s spontaneous breaths, but has a backup “mode” if the patient stops initiating breaths?

  • Volume Control – AutoFlow
  • PCV
  • PSV
  • PSVPro

PSVPro

400

Which ventilator mode relies entirely on spontaneous breaths by the patient, who must have an intact respiratory drive?

  • Spontaneous intermittent mandatory ventilation (SIMV)
  • Volume control
  • Pressure control
  • Pressure support

PSV

400

Plateau pressures greater than 35 cm H2O are associated with:

  • ARDS
  • Decreased cardiac output
  • Atelectasis
  • Barotrauma

Barotrauma

400

In PCV, which situation will INCREASE the patient’s tidal volume?

  • Trendelenburg position
  • Bronchospasm
  • Release of a pneumoperitoneum
  • Kinked ETT
