II. patient lung mechanics
III. patient effort
a.I and II
b.I and III
c.II and III
dI, II, and III

Answer 1

The volume delivered during pressure-targeted ventilation modes depends on set pressure limit, patient lung mechanics, and patient effort.

Step-by-step explanation:

The volume delivered during pressure-targeted modes of ventilatory support depends on several factors, including: set pressure limit, patient lung mechanics, and patient effort. The set pressure limit is a control on the ventilator that determines the maximum pressure allowed for inhalation, impacting the volume of air delivered. Patient lung mechanics, which involve lung compliance and resistance, affect how easily the lungs can be inflated. Finally, patient effort, the force generated by the patient's respiratory muscles, influences the volume inhaled during assisted breaths. Therefore, the correct answer to the question is dI, II, and III, reflecting these interconnected factors.
