What level of pH will determine the severity of respiratory acidosis ?

In brief: Acidosis....

Respiratory acidosis occurs when there is a build up of carbon dioxide (CO2) in the blood because the respiratory system is not getting rid of the CO2.
The kidneys will compensate by keeping bicarbonate (sodium bicarbonate) in the blood, thus lessening the degree of acidosis. A normal pH in the blood is 7.40 and anything less than 7.30 is worrisome! The pH, CO2 and O2 can be measured via blood gas analysis.

The level of pH & severity of respiratory acidosis will depends on acute vs chronic status. In acute onset, body won't have enough time to compensate & pH will decline quickly in hours which is very dangerous. On the other hand in chronic status due to adequate compensation by kidney pH will decrease slowly & pt tolerate very low pH such as 7.20 with minimal distress.

Thanks, Dr. Karim! Complex topic to discuss within the limited space provided!
