How should a casualty breathe to help with asthma?

• A. Rapidly through the nose
• B. Slowly and deeply against pressure
• C. Only through the mouth
• D. With a loud exhale

Answer: (B)

The correct approach for a casualty experiencing asthma is to breathe slowly and deeply against pressure. This technique helps to promote better oxygen exchange and can assist in calming the individual during an asthma attack. Breathing slowly helps to reduce anxiety, which can exacerbate asthma symptoms, and deep breaths allow for more effective ventilation of the lungs, promoting relaxation of the airways. Encouraging the casualty to take deep breaths can also create positive pressure in the airways, potentially helping to open them and improve airflow. It is essential during an asthma episode to avoid rapid or shallow breathing, as this can lead to hyperventilation and increased feelings of breathlessness. Breathing through the nose is not favored in this situation either, as it might not provide the necessary airflow that the lungs require during distress. Additionally, loud exhalations may indicate struggle and could lead to further panic, making it more challenging for the person to regain control over their breathing.
