Pengaruh Tindakan Closed Suction terhadap Saturasi Oksigen, Heart Rate dan Tekanan Darah pada Pasien yang Terpasang Ventilator di Ruangan ICU RSUP H Adam Malik

Abstract

The Intensive Care Unit (ICU) is one of the hospital rooms equipped with specialized staff and equipment to manage patients with life-threatening illnesses. The standard equipment in the ICU room is mechanical ventilation to assist breathing efforts through an endotracheal tube (ETT). The presence of an endotracheal tube in the airway causes tissue irritation and increases secretions. Suctioning is required in patients who are attached to a ventilator due to the inability to remove secretions independently. This study analyzed the effect of closed suction action on oxygen saturation, heart rate and blood pressure in patients attached to ventilators in the ICU room of the Hospital. H. Adam Malik Medan. Type of quantitative research method pre-experimental design with research design one group pretest-posttest design. The sample amounted to 199 respondents. The instruments used were demographic data questionnaires and observation sheets for saturation, heart rate and blood pressure. The results of multivariate analysis with Friedman showed there was a significant difference between saturation, heart rate and blood pressure before suctioning and after suctioning. Bivariate results with Wilcoxon test showed a significant difference in suctioning action on saturation before suctioning with saturation immediately after suctioning, 5 minutes after suctioning and 15 minutes after suctioning. There was a significant difference between heart rate before closed suction and heart rate (immediately after suctioning, 5 minutes after suctioning and 15 minutes after suctioning). There was a significant difference between systolic BP before closed suction and systolic BP (immediately after suctioning, 5 minutes after suctioning), but no significant difference when observed 15 minutes after suctioning. There was an effect between diastolic BP before closed suction and diastolic BP (immediately after suctioning), but there was no significant difference when observed 5 minutes after suctioning and 15 minutes after suctioning.
