Closed airway suction system
Repeated endotracheal suctioning performed with conventional disposable catheters involves disconnection of the patient from the ventilator – a procedure which is not without complications and risks.
Especially in patients depending on high PEEP levels or suffering from haemodynamic instability, interruption of ventilation can lead to:
- arterial and mixed venous oxygen esaturation
- loss of lung volume
- alveolar derecruitment in hypoxemic patients
-
increase in mean arterial
pressure and heart rate
