Respiratory System — Flashcards

Cheyne-Stokes breathing is defined by respirations that oscillate between _____ and hyperpnea.

The respiratory quotient, if someone is on an exclusive _____ diet, is 0.71.

The dorsal respiratory group receives sensory input from peripheral chemoreceptors via the _____ and vagus (CN X) nerves

Shifts of the O2-Hb dissociation curve to the _____ cause increased unloading of O2 at tissues

The lung diffusing capacity, DL, _____ in emphysema due to decreased surface area (A)

The partial pressure of O2 in arteriolar blood is slightly _____ than alveolar air due to the 'physiologic shunt''

Effects of Various Lesions and Brainstem Transections: Complete transection above pons with vagi _____ will lead to: Regular continued breathing, but depth of respiration increases

The _____ pressure across the lungs is calculated as alveolar pressure minus intrapleural pressure

Central chemoreceptors respond indirectly to increased _____ and directly to decreased pH

The V/Q ratio at the base of the lung is normally _____, indicating wasted perfusion
