2. What is high-frequency ventilation (HFV)? Helps avoid large swings of intrapulmonary pressures HFV rates are equal to 100Hz or more as needed HFV volume is greater than anatomical deadspace Respiratory rates are set at less than 20 breaths per minute
3. Resonance frequency describes a phenomenon where less ____________ is required to move gas in and out of the lungs. Fluid Temperature Volume Energy/Pressure
4. What is the primary impedance for gas exchange? Airway resistance Dynamic compliance Flow Volume
