ABSTRACT
Objective To evaluate the correlations between arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2) and age in the population of Han nationality aged over 15 years old. Methods Three hundred Chinese Han nationality patients who underwent elective surgery were selected. They were involved in ASA class Ⅰ-Ⅲ, including 162 male and 138 female. Radial artery or dorsalis pedis artery was punctured, performed indwelling catheter, and connected the pressure transducer under local anesthesia. Blood gas analysis was collected before anesthesia. Results The linear regression trend diagram showed that the level of PaO2 had linear negative correlation with age . The calculating formula was PaO2(mmHg) = 101.7- 0.278 × age (years) (1 mmHg = 0.133 kPa, R2=0.903). The level of PaCO2 didn′t change with age, and average was (38.2 ± 2.8) mmHg. Conclusions The level of PaO2 is gradually decreased with age, but the level of PaCO2 isn′t affected by age.
