What parameter is used to evaluate the respiratory component of acid-base balence | Paco2 |
What is a base? | A base excepts H+ ions |
What is an acid | An acid donates H+ ions |
The metabolic component of acid base balence is primarily controlled by the : | Renal system |
The respiratory component of acid base balence is controlled by | the pulmonary system |
normal value for pH | 7.40 |
normal value for PvCO2 | 48 |
normal value for PvO2 | 40 |
normal value for SvO2 | 70-75 |
What is meant by the term mixed venous blood? | An average of all venous values in the body coming back to the heart. |
Mixed venous blood is obtained by what anatomical area? | Blood from the right atrium where blood is being dumped from the SVC and IVC. |
pH2O at BTPS is | 47 torr |

What is a volatile acid? | An acid that can change from a liquid state to a gas, an example is H2CO3 |
The numerical difference between the normal total base in a blood sample and the actual amount of base in the sample is called | base excess |
