When the dead space–to–tidal volume ratio (VD/VT) is calculated, VD refers to the _____ dead space.

To minimize the magnification associated with portable films, how far should the patient and the film be from the source of the x-rays in a conventional chest x-ray?

Given : corrected tidal volume = 650 ml, plateau pressure = 30 cm H2O, and PEEP= 10 cm H2O. Calculate Static compliance.

Given: flow = 7 l/min, the inspiratory time = 0.5 sec. Calculate the delivered tidal volume based on these settings on a constant flow time-cycled ventilator.

A nonintubated patient should be monitored for lung volumes in the presence of the following clinical conditions except:

The amount of force needed to overcome opposition to air flow in the lungs during mechanical ventilation is known as:

Which equation is used to determine Rapid Shallow Breathing Index (RSBI):

Given : corrected tidal volume = 700 ml, PIP = 29 cm H2O, PPlat = 25 cm H2O and PEEP= 0 cm H2O. Calculate dynamic compliance.

Given:VC = 3500 mlTV = 450 mlFRC = 3000 mlRV = 900 mlDetermine : IRV =______________, IC = ________________                  ERV = ____________, TLC = _______________

Which equation is used to determine tidal volume based on flow:
