Sub-Category:

Smoke Inhalation

Category: Occupational and Environmental Lung Diseases

Sub-category: Environmental Exposures

Symptoms:
shortness of breath; cough; soot in the mouth or nose; wheezing; burning sensation in the throat or chest; confusion or altered mental state (in severe cases)

Root Cause:
Inhalation of smoke, which can contain toxic gases, particulates, and chemicals that cause irritation, damage to the respiratory system, and inflammation in the airways and lungs.

How it's Diagnosed: videos
Diagnosis is primarily clinical, based on a patient's history of exposure to smoke, physical examination, and symptoms. Imaging such as chest X-ray or CT scan may be used to assess lung damage. Blood gases may be taken to evaluate respiratory function.

Treatment:
Oxygen therapy to improve oxygen levels. Bronchodilators to open airways. Steroids to reduce inflammation. Supportive care including fluids and monitoring in severe cases.

Medications:
Bronchodilators (e.g., albuterol , salbutamol) to relax the muscles of the airways and improve airflow. These are beta-agonists that act as bronchodilators. Corticosteroids (e.g., prednisone ) to reduce inflammation in the airways. Analgesics (e.g., acetaminophen or ibuprofen ) for pain management.

Prevalence: How common the health condition is within a specific population.
Occurs frequently in fire-related incidents, with thousands of cases annually. It can also affect individuals who work in industries with high exposure to smoke, such as firefighting.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Exposure to high levels of smoke (e.g., during fires). Occupations involving exposure to smoke (e.g., firefighting). Pre-existing respiratory conditions (e.g., asthma, COPD).

Prognosis: The expected outcome or course of the condition over time.
Prognosis can vary depending on the severity of inhalation and lung damage. Mild cases generally recover fully with treatment, while severe cases may result in long-term lung damage and even death.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Respiratory failure. Acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). Chronic lung disease (e.g., COPD). Infections due to weakened immune system or lung damage.

Chemical Inhalation (e.g., ammonia, chlorine)

Specialty: Pulmonology

Category: Occupational and Environmental Lung Diseases

Sub-category: Environmental Exposures

Symptoms:
cough; shortness of breath; chest tightness; burning sensation in the throat, nose, or eyes; watery eyes or conjunctivitis; nausea or vomiting; wheezing or stridor (if airway is affected)

Root Cause:
Inhalation of toxic chemicals such as ammonia or chlorine leads to direct irritation of the respiratory tract, causing inflammation, bronchoconstriction, and potentially chemical burns to the airway and lung tissue.

How it's Diagnosed: videos
Diagnosis involves a detailed history of exposure, clinical examination, and lung function tests. Imaging like chest X-rays or CT scans may be used to detect any structural damage. Blood gases may be assessed to evaluate oxygenation.

Treatment:
Removal from the source of exposure. Oxygen therapy to support breathing. Bronchodilators (e.g., albuterol) to relieve wheezing and bronchospasm. Corticosteroids to reduce inflammation in the lungs. Supportive care for more severe cases.

Medications:
Bronchodilators (e.g., albuterol ) are prescribed to relieve bronchospasm. Corticosteroids (e.g., prednisone ) to control inflammation. Antibiotics if secondary infection develops in severe cases.

Prevalence: How common the health condition is within a specific population.
Chemical inhalation injuries are relatively rare but occur in industrial settings, accidents, or exposure to household products. Ammonia and chlorine are common in industrial accidents.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Occupations involving chemicals (e.g., industrial workers, cleaners). Accidental chemical spills or exposure. Lack of personal protective equipment (PPE) during work. Proximity to hazardous materials or inadequate ventilation.

Prognosis: The expected outcome or course of the condition over time.
The prognosis depends on the concentration of the chemical and the duration of exposure. Mild exposures often resolve without long-term effects, but severe cases may result in permanent lung damage or even death.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Chronic respiratory problems (e.g., asthma-like symptoms). Pulmonary edema (fluid in the lungs). Acute respiratory distress syndrome (ARDS). Chemical burns to the airway.
