Suctioning

Definition:

Suction is the removal of retained secretions through oropharyngeal, endotracheal, or tracheostomy tube and it should be performed whenever clinically indicated rather than on affixed schedule.Increase in peak airway pressures when patient is on mechanical ventilation.Endotracheal suctioning

Definition:

It is the mechanical aspiration of tracheal secretions using a negative pressure by passing a sterile catheter into the trachea through an artificial airway (endotracheal or tracheostomy tube).Artificial airway suctioning (Endotracheal or tracheostomy).-To obtain samples of tracheal secretions for laboratory analysis.Oral suctioning (Oropharyngeal suctioning).2.3.2.3.4.

Suctioning

Definition:

Suction is the removal of retained secretions through oropharyngeal, endotracheal, or tracheostomy tube and it should be performed whenever clinically indicated rather than on affixed schedule.

Routes of suction:

1. 
   

   Oral suctioning (Oropharyngeal suctioning).

   
   


2. 
   

   Nasal suctioning (Nasopharyngeal suctioning).

   
   


3. 
   

   Artificial airway suctioning (Endotracheal or tracheostomy).

   
   

Endotracheal suctioning

Definition:

It is the mechanical aspiration of tracheal secretions using a negative pressure by passing a sterile catheter into the trachea through an artificial airway (endotracheal or tracheostomy tube).

Purposes:

-To maintain patency of artificial airway.

-To improve gas exchange.

-To decrease airway resistance.

-To reduce infection risk by removing secretions from the trachea and main stem bronchi.

-To obtain samples of tracheal secretions for laboratory analysis.

Indications:

Tracheal suctioning should be performed only for a clinical indication and not as a routine, fixed -schedule treatment, clinical indication for tracheal suctioning includes:

1. 
   

   Secretions in the artificial airway.

   
   


2. 
   

   Suspected aspiration of gastric or upper airway secretions.

   
   


3. 
   

   Auscultation of adventitious lung sounds over the trachea or main stem bronchi or both.

   
   


4. 
   

   Increase in peak airway pressures when patient is on mechanical ventilation.
