For the lung as a whole, the mixed arterial concentration is a blood flow–weighted mean of the values for several compartments, and the mean expired level is similarly a ventilation-weighted mean of the compartmental values. These parameters are measured directly, together with the cardiac output...
Also, the lungs are unidirectionally ventilated rather than having a tidal, bidirectional flow, as in other vertebrates with lungs. To achieve…Read More In human respiratory system: Chemoreceptors Ventilation levels behave as if they were regulated to maintain a constant level of carbon dioxide part...

The regional ventilation–perfusion ratio will determine the partial pressures of oxygen and carbon dioxide found in the alveoli at a given level of the lung, and this will be reflected in the gas tensions found in pulmonary venous blood draining those alveoli. ...

Bilevel ventilation (BiPAP) with a lower expiratory pressure is more comfortable and better for correcting CO2 retention. Automatically adjusting the CPAP (Auto-CPAP) device has the same efficacy as CPAP on sleep apnea; however, it is not recommended to treat hypoventilation. Sometimes assisted ...
