With pressure cycled ventilators gas flows into the lungs until a pressure limit is reached, then a valve opens to allow the patient to exhale. The volume delivered by the ventilator varies with changes in airway resistance, lung compliance, and integrity of the ventilatory circuit which is why it is super important to monitor the volume to make sure the patient is not in any distress// receiving the appropriate volume each breath.

Changing inspiratory pressure or inspiratory time will change the delivered tidal volume. Changing the I:E ratio changes the inspiratory time, and vice versa. When changing respiratory rate, keep the inspiratory time constant so as not to change the tidal volume, although this will alter the I:E ratio.

a. 32 L/min
b. 20 L/min
c. 12 L/min
d. 8 L/min
a. 32 L/min

d. High PEEP
Which of the following would be MOST helpful for a patient with fixed upper airway obstruction?
a. Bronchodilator
b. NO
c. Heliox therapy
d. BMV followed by endotracheal intubation
c. Heliox therapy
HELIOX is a mixture of Helium and Oxygen. It is a therapeutic modality that can improve upper and lower airway obstruction. The lower density of Helium can help to relieve airway obstruction and is known to lower the work of breathing.
