Respiratory Obstruction

What is Respiratory Obstruction?

First of all, respiratory tract obstruction is when the airway is blocked to a certain extent, preventing the passage of air necessary for breathing, making breathing difficult. Respiratory obstruction, which is divided into two types: complete obstruction or partial obstruction, is a problem that requires urgent intervention.

What are The Causes of Respiratory Obstruction?

What causes respiratory tract obstruction, which can be experienced by everyone in daily life, is among the most wondered questions. There are many factors in this disorder, which can be experienced by anyone from 7 to 70.

When looking at the factors that block the respiratory tract:

What are The Types of Respiratory Obstruction?

  1. Partial Clogging:

The situation where there is some air passage, even if it is small, is called partial blockage.

  1. Complete Clogging:

The situation where the air inlet is completely blocked is called complete blockage.

What are The Symptoms of Partial Clogging and Complete Clogging?

In this case, the Heimlich Maneuver (Abdominal Compression) is performed.

Heimlich Maneuver (Applying Abdominal Compression)

The Heimlich maneuver is a first aid method that helps open the airway of a person whose throat or trachea is blocked for any reason by applying pressure to the abdomen.

When a foreign object gets stuck in the throat, the Heimlich maneuver is one of the primary methods used to remove the object. In this method, which is applied individually and includes several techniques, it is necessary to know the basic information.

In such cases, when airway obstruction is suspected, first aiders will perform Basic Life Support.

If air does not escape after rescue breathing is given, it is thought that there is an obstruction. The first aider should check whether there is a foreign object in the mouth, and if he sees a foreign object, remove it.

Common Questions on Respiratory Obstruction

What is respiratory obstruction and why is it dangerous?

Respiratory obstruction is any narrowing or blockage in the airway that prevents air from entering or leaving the lungs. It is considered a medical emergency because it restricts the body’s intake of oxygen ($O_2$) and the removal of carbon dioxide ($CO_2$).

If the obstruction is complete, it can lead to respiratory arrest and permanent brain damage within minutes due to hypoxia (lack of oxygen in tissues).

What are the most common causes of an obstructed airway?

Causes can be categorized by how quickly they occur:

  • Acute Causes: Choking on food or foreign objects, severe allergic reactions (anaphylaxis) causing throat swelling, or trauma to the neck.
  • Chronic Causes: Chronic Obstructive Pulmonary Disease (COPD), asthma, tumors, or long-term inflammation of the bronchial tubes.
  • Infectious Causes: Severe cases of epiglottitis or croup (common in children).
How do you identify the signs of a respiratory obstruction?

Clinical signs vary depending on the location of the blockage. Key symptoms to watch for include:

  • Stridor: A high-pitched, whistling sound heard when breathing in.
  • Retractions: The skin pulling in around the collarbone or ribs during breathing attempts.
  • Cyanosis: A bluish or grayish tint to the lips, skin, or fingernails.
  • Agitation and Panic: Gasping for air or clutching the throat (the universal choking sign).
What is the difference between partial and complete obstruction?

It is crucial to distinguish between these two for proper first aid:

Partial Obstruction: The person can still cough, speak, or make some noise. In this situation, you should encourage them to cough forcefully to clear the blockage themselves.

Complete Obstruction: The person cannot breathe, cough, or speak at all. They may turn blue quickly. This requires immediate intervention like the Heimlich maneuver or emergency medical services (EMS).

How is a respiratory obstruction treated by medical professionals?

Doctors use various advanced techniques to restore airflow:

  • Intubation: Passing a tube through the mouth into the trachea.
  • Bronchoscopy: Using a camera-equipped tool to locate and remove foreign objects.
  • Cricothyrotomy: An emergency surgical procedure to create an airway through the neck when the upper airway is totally blocked.
  • Medication: Bronchodilators for asthma or epinephrine for allergic reactions.
