Airway management is a process used to ensure that a patient is able to breathe and perform gas exchange. It involves suctioning, airway maintenance, establishing an artificial airway, and extubation.
It goes without saying that this is a very important topic in the field of respiratory care.
In this article, we will provide an overview of airway management and break it down in a way that’s easy to learn and understand. We included helpful practice questions for your benefit as well.

What is Airway Management?
This is important because we need to keep a patient’s upper airway free and clear of foreign substances so that air can flow into and out of the lungs.
Types of Airway Management
Airway management involves multiple medical procedures, including:
- Endotracheal suctioning
- Sputum sampling
- Artificial airways
- Emergency surgical airways
- Securing the airway
- Confirming proper tube placement
- Secretion clearance
- Tracheostomy care
- Troubleshooting airway emergencies
These are examples of the common procedures that are involved in the process of airway management. Respiratory therapists are involved every step of the way. Again, that is why this is such an important topic.
What is an Artificial Airway?
An artificial airway is a tube that is inserted into the patient’s trachea in order to maintain breathing and ventilation.
This is necessary when a patient is unable to maintain their own airway or if they are at risk of aspirating. In this case, an artificial airway is used to establish a link between the patient and the mechanical ventilator. There are three primary types:
- Endotracheal tube
- Tracheostomy tube
- Pharyngeal airways
Each type has different uses and advantages. However, in order to function properly, they must be inserted and maintained correctly, which is the job of a respiratory therapist.
An endotracheal tube is a small, flexible tube that is inserted through the nose or mouth into the trachea. This is necessary to establish an artificial airway for a patient in need of mechanical ventilation.
The endotracheal tube is secured in place with tape or a tying device, and the insertion process is known as intubation.
A tracheostomy tube is a small, flexible tube that is inserted through an incision in the neck and into the trachea. This is generally done when a patient is unable to tolerate intubation or if they are in need of long-term ventilatory support.
After a tracheostomy tube has been inserted, it is the responsibility of the respiratory therapist to maintain the tube in place and keep the incision site clean. This is known as tracheostomy care.
Pharyngeal airways are small tubes used to prevent obstructions and extend only into the pharynx. There are two types:
- Nasopharyngeal airway
- Oropharyngeal airway
A nasopharyngeal airway is a small tube that is inserted into the nasal passage of patients who require frequent nasotracheal suctioning.
An oropharyngeal airway is a small tube that is inserted into the mouth of an unconscious patient to prevent the tongue from causing an obstruction.
Intubation is the process of inserting a tube into the trachea in order to establish an airway and facilitate breathing support via mechanical ventilation. This creates a link between the patient and the ventilator so that gas exchange can occur.
During an intubation procedure, patients are administered anesthesia and a muscle relaxant in order to minimize discomfort and relax the muscles of the airways.
A laryngoscope blade is used to open the mouth in order to visualize the vocal cords. Then, a flexible plastic tube is inserted through the patient’s mouth or nose, through the vocal cords, and into the trachea.
The tube can be secured by inflating the small cuff that surrounds the tube with air in order to provide stability and help keep it in place.
The process of intubation is typically the same in patients of all ages. The only difference is in the size of the equipment used during the process of insertion.
For example, pediatric patients will require a much smaller endotracheal tube than adult patients. Male patients may sometimes require a larger tube than female patients.
The physical insertion of the endotracheal tube is a procedure that requires a trained and skilled professional, which is why it’s most commonly performed only by doctors and respiratory therapists.
Airway suctioning is the process of clearing secretions from a patient’s airway. This is typically done using a suction catheter, which is a thin, flexible tube with a small opening at the end.
The catheter is inserted through the nose or mouth and down into the airway. It uses negative pressure from a vacuum source to suction mucus and secretions from the patient’s airways.
Suctioning is an important part of respiratory care, as it helps to keep the airway clear and free of obstructions so that breathing can occur. It is performed on a regular basis by respiratory therapists and nurses.
Intubation and mechanical ventilation are only temporary for most patients. Therefore, at some point, the artificial airway must be removed, which is a procedure known as extubation.
The decision to extubate a patient is based on many factors, including:
- Ability to protect their airway
- Adequate respiratory function
- Ability to manage secretions
- Adequate oxygenation
- Stable hemodynamic status
- Ability to cooperate with the medical team
The respiratory therapist or physician will generally perform the extubation procedure. This involves oxygenating the patient, deflating the cuff, removing the tube, suctioning secretions, and assessing and closely monitoring the patient.

What are Retained Secretions?
Retained secretions are any secretions that remain in the airways of the lungs. This can be due to a variety of factors, including an inadequate cough, muscle weakness, impaired mucus clearance, and dehydration.
Secretions that are not cleared from the lungs can lead to respiratory infections, atelectasis, and pneumonia. Therefore, they should be removed by suctioning, which is a procedure that is performed by the respiratory therapist.
What is Sputum Sampling?
A sputum sample is a sample of the secretions that are coughed up from the lungs. This can be used to diagnose various lung diseases.
To obtain a sputum sample, a patient will be asked to cough up some of their secretions into a container. This can be done by coughing into a cup or by using a suction device.
What is an Emergency Surgical Airway?
An emergency surgical airway is a last resort when all other attempts at airway management have failed. For example, the patient’s physiological condition could make it difficult or impossible to perform intubation.
In this case, a transtracheal airway must be established by making an incision in the trachea and inserting a tube into the opening.
This is known as a cricothyroidotomy and is a life-saving procedure that should only be performed by trained medical personnel.
How to Secure an Artificial Airway?
Once an artificial airway has been established, it is important to secure it in place. This is done by inflating the cuff that is attached to the tube. The cuff creates a seal around the tube, which prevents air from leaking around the tube.
It should also be secured with tape or a tying device. This helps prevent the tube from being dislodged.
How to Confirm Endotracheal Tube Placement?
There are several ways to confirm that an endotracheal tube is in the correct location. These include:
- Auscultate the chest and abdomen
- Look for chest movement
- Check the tube length and position
- Use capnometry
- Use colorimetry
- Use ultrasound
- Order a chest x-ray
Each procedure can be performed immediately after intubation to confirm proper tube placement. However, the most accurate method of confirmation is using a chest x-ray. This will show the placement of the tube in the trachea.
Airway management is a critical subject in respiratory care. It’s important to understand the techniques of each procedure and learn about the various types of artificial airways.
This will allow you to provide the best possible care for your patients. We have a similar guide on the topic of intubation that I think you’ll find helpful.
Thank you so much for reading and, as always, breathe easy, my friend.
