A comparative study to assess the effectiveness of open tracheal suction system and closed tracheal suction system on physiological parameters

A comparative study was conducted to assess the effectiveness of open tracheal suction system and closed tracheal suction system on physiological parameters among the mechanically ventilated patients at critical care unit of sangli city. A non experimental quantitative (descriptive) research design was used in this study. Forty patients on mechanical ventilation attending from the previous setting were included in the study.

Observation checklist was used. One tool was divided into two parts used in this study open tracheal suction system and closed tracheal suction system, data were obtained firstly by using a socio-demographic data form of patients, the second is the clinical patient's data and the third part is an assessment tool for physiological parameters heart rate, Respiration rate, blood pressure and O2 saturation in three consecutive times for three days.

Study shows that there is significant difference in Heart Rate and Blood Pressure in open tracheal suction system as the p value is less than 0.05 and there is no significant difference in Respiration Rate and Oxygen rate as P value is more than 0.05. Shows that there is significant difference in Heart Rate, Blood Pressure Respiration Rate and Oxygen rate in closed tracheal suction system as the p value is less than 0.05.
