Study Notes

Breathlessness Overview

Learning outcomes include understanding patient experiences, identifying bodily systems causing breathlessness, diagnosing causes, and describing environmental risks for respiratory disease.
Acute breathlessness signifies a sudden change, while chronic breathlessness is typically experienced during exertion and might eventually occur at rest.
Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation, progressing over time.
Breathlessness is often described as dyspnea, a need to breathe, or shortness of breath (SOB).
Common causes of breathlessness can include lung problems, heart or circulatory issues, breathing pattern disorders, deconditioning, oxygen transport issues, and acid-base imbalances.

Breathing and Circulation

The respiratory process involves external respiration (pulmonary ventilation and gas exchange) and internal respiration (systemic tissue gas exchange and cellular respiration).
Pulmonary circulation and systemic circulation facilitate gas transport throughout the body.
The respiratory control centers regulate breathing based on oxygen, carbon dioxide, and pH levels sensed by sensors.

Pollution

Particulate matter (PM), including PM2.5, PM10, and other pollutants, can affect respiratory health.
Nitrogen dioxide (NO2) is another air pollutant linked to respiratory issues.
Pollution is a key environmental risk factor for respiratory diseases like COPD.

COPD Diagnosis

COPD is diagnosed using a spirometry test.
An FEV1/FVC ratio below 0.7 indicates COPD and can be categorized as mild, moderate, severe, or very severe based on the predicted FEV1 percent.
COPD diagnosis often involves a patient history, along with physical examinations and tests.

COPD Risk Factors

Smoking is a significant risk factor for COPD, accounting for approximately 90-95% of cases.
Environmental factors like dust, particulates, and fumes increase COPD risk.
Women may be more susceptible to COPD than men.

COPD Treatment

Smoking cessation is crucial in COPD management.
Vaccination against influenza and pneumococcus is recommended.
Pulmonary rehabilitation, weight loss, inhalers, oral steroids, antibiotics, surgical interventions, and long-term oxygen therapy are potential COPD treatment options.

COPD Prognosis

COPD progression is generally characterized by a decline in lung function over time, quantified by FEV1 percentage.
Smoking status strongly correlates with the progression rate of symptoms, such as symptoms, disability, and death associated with COPD.
Movement relies on adequate oxygen delivery.
Many disease causes acute and chronic breathlessness.

COPD Summary

COPD incidence is expected to increase over the coming years.
Healthy lifestyle choices, like avoiding smoking and a healthy active lifestyle, reducing pollution, and vaccinations, are crucial preventive measures.
COPD frequently leads to reduced weight gain and related malnutrition.
A variety of acute and chronic disease conditions can cause issues with breathing.
