How do you use a closed suction catheter?
Keeping this in view, what is a closed suction catheter?
Catheter suction is used to remove tracheal secretions through the endotracheal tube in mechanically ventilated patients, which may be either closed tracheal suction system (CTSS) or open one. In CTSS, the catheter is a part of ventilator circuit with no need to disconnect the ventilator.
Regarding this, what is open and closed suctioning?
Closed versus open suctioning techniques. Alternatively, it can be accomplished with a closed suctioning system included in the ventilatory circuit, allowing to introduce the suction catheter into the airways without disconnecting the patient from the ventilator.
Insert the suction catheter until the centimeter markings on the ETT and the centimeter markings on the suction catheter are aligned. Insert the suction catheter no more than 1 cm further.
