Abstract
Objective: To evaluate the influence of closed suction systems on oxygen saturation, heart rate, and blood pressure in patients on mechanical ventilation.
Methodology: This study used a pre-experimental one-group pretest-posttest design in an intensive care unit. A purposive sample of 199 respondents was included. Data collection was from February to April 2024. We recorded oxygen saturation, heart rate, and blood pressure before suctioning, immediately, five minutes, and 15 minutes after suctioning. Data were analyzed using frequency, percentage, Friedman, and Wilcoxon for post hoc analysis.
Results: A closed suction system before suctioning, immediately after suction, five minutes after suction, and 15 minutes after suction showed mean oxygen saturation was 92%, 94%, 96%, and 98%; heart rates per minute were 108, 109, 100, and 93; and blood pressure (systolic/diastolic mmHg) was 125/77, 128/79, 121/77, and 118/76. The Friedman test showed significant differences in SpO2, heart rate, and blood pressure between before and immediately after suctioning, five minutes after suctioning, and 15 minutes after suctioning (p=0.001).
Conclusion: The application of closed suction system in the ICU showed promising results in maintaining the hemodynamic status of patients with mechanical ventilation.

Key words: Closed suction, oxygen saturation, blood pressure, heart rate.
