The impact of open vs closed suction on cardio- respiratory parameters in mechanically ventilated patients

Abstract

Suctioning of the endotracheal tube in ventilated patients is one of the ways to maintain the airway open. There arevarious risks associated with this procedure. Suctioning methods that are appropriate for the situation can help to avoid acute problems. The purpose of this study was to compare the effects of open vs closed suction on cardiorespiratory parameters in patients on mechanical ventilations. Patients hospitalized to Neuro-ICU and Medical ICU with ventilator support was studied in a non-randomized clinical trial with a time series study design. Sixty samples were chosen using a convenient sampling procedure, including 30 for open suction and 30 for closed suction. Before and during suction, data such as demographic factors and cardio-respiratory parameters such as respiratory rate, heart rate, mean arterial pressure, and SpO2 were measured. In this study, statistically significant changes (p=0.001) in Mean Arterial Pressure (MAP) and SpO2 were identified when open and closed suction systems were compared. According to the findings, closed suction has a significant favourable impact on cardiopulmonary parameters.
