Reduced in banked blood

Carbon dioxide production
Respiratory rate

Ambient pressure
FiO2
PaCO2
PaO2

Morbid obesity
Supine positioning

Elevated carbon dioxide

Chronic obstructive pulmonary disease

Increase in A-a gradient

Hydrogen

Converted to bicarbonate

Hypoventilation

A dead space alveolus can transfer relatively more CO2 than O2

Positive pressure ventilation
One liter of rapid blood loss

Respiratory rate
Inspired oxygen

Paradoxical reflex of the head + 1st breath of a newborn
Pulmonary C receptors + Tachypnea in the presence of vascular congestion
Hering Breuer deflation reflex + Triggers deep breathing when lung volume is low
Hering Breuer inflation reflex + Stops inspiration at high lung volume

2 mL/kg

Inhibition of the dorsal respiratory group from the pneumotaxic center

Respiratory bronchioles
Alveolar ducts

Decreasing the affinity of hemoglobin for oxygen

Endotracheal tube

HCO3- movement out of the RBC followed by Cl- entry
