ALTERATION IN BLOOD OXYGEN LEVEL DUE TO BAG AND TUBE VENTILATION BEFORE SUCTIONING AMONG PATIENTS ON MECHANICAL VENTILATOR

Abstract

Patient on ventilator suffer from gag reflex and hyper ventilation during suctioning. Hyper oxygenation before and after suctioning should be performed to decrease the occurrence of arterial desaturation with suctioning. Hypoxemia can be minimized by preoxygenating the patient with 100% oxygen prior to suctioning and between each pass of the suction catheter. This is mainly done by pushing 100% oxygen with bag device. The duration of each suction pass should be limited to 10 seconds.The present study was carried out with the aim to describe the alteration in blood oxygen level due to bag and tube ventilation before suctioning among patients on Mechanical Ventilator in Shimla 2013. Study subjects were forty . Majority of study subjects were in the range of 41-60 years, among them 70.0% were male and 30.0% were females. Blood was collected for selected parameters i.e.PH,PaCO2, PaO2 and readings of blood oxygen level(spo2) recorded by the investigator. The data obtained was compiled, tabulated and analyzed using appropriate statistical methods. Results showed that ‘t’ value was significant at level of 0.05 for SPO2, PH, Pao2 . Therefore the inference was drawn that bag and tube ventilation improved the SPO2, PH, , PaO2 levels among the study subjects .whereas the PaCO2 t value was not significant, therefore conclusion was drawn that bag and tube ventilation bring the alteration in PaCO2 negatively whereas in other selected parameters it brings alteration positively. Association between the age and sex of study subjects related to post bag and tube ventilation. The ‘t’ value of the age 2.5 whereas in case of sex it was 0.75 respectively. Hence, the conclusion was drawn from the Demographic variable i.e Age and Sex may have altered the observation due to smaller sample size and’t’ value can be non significant if study is done on larger sample.
