A Suction Catheter is made from biocompatible, medical-grade materials such as PVC or silicone and is connected to a suction device. The catheter is inserted into the patient’s airways through the mouth, nose, or endotracheal tube, directing secretions out through suction. The end of the tube has holes to facilitate better suction of the secretions.
Suction catheters come in various sizes ranging from 6 to 18 French (Fr). The appropriate size depends on the patient’s age and condition. Smaller sizes (6–8 Fr) are used for infants and children, while larger sizes (14–18 Fr) are used for adults. Selecting the correct size is crucial to ensure the catheter fits comfortably in the patient’s airway while minimizing the risk of tissue damage.
Suction catheters are designed in different types, each suited for specific applications:
Regular Catheters: Used for general suction of secretions from the airways.
Controlled Catheters: Feature a side valve to regulate suction manually, giving healthcare providers control over the suction strength.
Closed or Isolated Catheters: These catheters are packaged in a sterile container and are primarily used for patients on ventilators. This type is designed to reduce the risk of infection in sensitive patients.
Suction catheters are vital tools for clearing the airways, available in various sizes and types to cater to different patient needs. They help maintain airway health and prevent infections, playing an important role in improving breathing and patient safety.
