title: [Clinical observation of the effect of blood gas with two different methods of sputum suction].
abstract: The authors observed the preventive effect of the oxygen supplied double channel sucker on low blood oxygen. Thirty patients with channel sputum sucker under the mechanical respiratory support were taken as the contrast group, in comparison with the experimental group A and B respectively. Patients (n = 30) with one channel sputum sucking for 15 sec. were designated as experimental group A, while the other patients (n = 30) with the oxygen supplied double channel sucking for 15 sec were the group B, Blood gas analysis was done in every patient of each group. Significant difference of PO2 was found between group A and the contrast group (P < 0.01). No significant difference was found between group B and the contrast group (P > 0.05). It shows that oxygen supplied double channel sucker has preventive effect on low blood oxygen, and is suitable for sputum sucking in severe patients.
