Mechanical ventilation is an important life‐saving technology. There are a number of related problems that contribute to the morbidity and mortality of patients receiving mechanical ventilation in intensive care unit. Therefore, it became vital to use the safest and most effective method of ventilation for the shortest possible duration. Hypertonic saline Nebulized suctioning has been used to strengthen lung clearance and reduce infection in intubated patients. Quantitative evaluative approach of one group pretest posttest design was used to test the effectiveness of 3% hypertonic saline nebulized suctioning on airway clearance. Patients were selected by convenience sampling technique and sample consists of 30 mechanical ventilated patients in ICU PESIMSR at Andhra Pradesh. Semi structured interview schedule and modified bio- physiological parameters with arterial blood gas analysis scale were used. The level of airway clearance were recorded before and after administration of 3% hypertonic saline nebulized suctioning. Descriptive and Inferential statistics were used to investigate data collected in terms of policies. The analysis exhibits that, there was significant difference in mean value between pretest (7.96+ 2.93) and posttest (2.74+2.93). paried ‘t’ calculated value was 8.46 greater than the table value, known to that there is an effectiveness of 3% hypertonic saline nebulisation on airway clearance among the patients connected with mechanical ventilator. The study suggests that the significant relationship between the post tests score with their selected demographic and clinical variables like gender, patient positioning during suctioning. The study has shown that hypertonic saline nebulization is the cheap, safe, effective and easy way to maintain the airway patency of patients connected to artificial airway.
