Suction catheters are long flexible tubes that are used in intensive care to remove fluids from the mouth and airways of critically ill patients. Critically ill patients often have difficulty with swallowing or coughing. Removal of these fluids is important to ensure the lungs remain clear and the patient is able to breathe properly.

Please note these translations are based on an earlier version of this description.
The suction catheter and suction tubing are connected to a collection container (suction canister) and a device that generates suction. This is a single use catheter which is used most often when the patient does not have an artificial airway such as an endotracheal tube or tracheostomy in place. An ‘inline suction device’, where the suction catheter is enclosed in a plastic sleeve, is commonly used when a patient has a breathing tube in place. These are changed every 2-3 days.
The catheter is gently inserted into the patient’s airway and suction applied, thus removing any secretions or fluids. Suction will be performed by physiotherapists, nurses or doctors.
For a more detailed explanation of how suction catheters are used please see ‘suctioning an artificial airway’.
Suctioning can be distressing for the patient however removal of these secretions is vitally important for the recovery of the patient. All Intensive Care interventions and procedures carry a degree of potential risk even when performed by skilled and experienced staff. Please discuss these issues with the nursing staff and medical who are caring for the patient.
Of course, if you have any questions or concerns, please discuss them with the ICU nurses and doctors.
