| Abstract |
|
The most important factor in clinical development of respiratory care has been the clinical availabiTity of blood gas and pH measurement and it is important to get the accurate values of those. There can be an error to get the value of PCO2, PO2 and pH by dilutional effect of liquid-Naheparin that is usally used as an anticoagulant. We compared values of 20 arterial blood gases sampled with 1 cc plastic syringe utilizing liquid-Na-heparin with those ones sampled with 1 cc arterial blood gas kits which were pre-filled with dry-Lithium-heparin. The results were as follows; 1) There are no difference in values of PO2 and pH between two groups. 2) The value of PCO2 sampled with 1 cc plastic syringe utilizing liquid-Na-heparin is 1.62 torr less than the value of that with 1 cc arterial blood gas kits which were pre-filled with dry-Lithium-heparin (p<0.05). |
