PERUBAHAN SATURASI OKSIGEN DENGAN HIPEROKSIGENASI PADA TINDAKAN CLOSED SUCTION PASIEN DENGAN ETT DI RUANG ICU RS ROEMANI MUHAMMADIYAH SEMARANG

Abstract

Patients with an Endotracheal Tube (ETT) in the ICU are at risk of secretion retention and decreased oxygen saturation. One of the nursing interventions performed is suctioning, which has the potential to cause hypoxemia complications. Therefore, pre- and post-suction hyperoxygenation is required to maintain oxygenation and prevent desaturation. Objective : This study aimed to analyze the effectiveness of hyperoxygenation before and after closed suction on changes in oxygen saturation in ICU patients with ETT. Method : This case study was conducted on five patients in the ICU of Roemani Muhammadiyah Hospital Semarang with various medical diagnoses, including respiratory failure, bronchopneumonia, cardiogenic shock, and pulmonary edema. Inclusion criteria were patients with ETT, mechanically ventilated, requiring suctioning, and in stable condition for hyperoxygenation. Instruments used included a pulse oximeter to measure oxygen saturation (SpO₂) and a ventilator monitor to record respiratory rate. The intervention involved administering 100% oxygen for 30–60 seconds before and after closed suction according to the standard operating procedure. Result : The majority of patients (80%) experienced an increase in oxygen saturation ≥3% with improvement in respiratory rate, while 20% of patients remained stable without further decline. No patients experienced deterioration after the intervention. Conclusion : Hyperoxygenation is effective in maintaining respiratory stability, preventing hypoxemia, and supporting vital organ function during closed suction procedures in mechanically ventilated patients.
