Which step should come first when instructing a patient on controlled coughing?

The first step in instructing a patient on controlled coughing is to take several deep breaths. This action is important because it helps to maximize lung expansion, ensuring that the lungs are well-aerated before the coughing occurs. By taking deep breaths, the patient can mobilize secretions and improve oxygenation, which is essential for effective coughing. This foundational step prepares the respiratory system and promotes optimal gas exchange, essential for clearing any blockages or mucus from the airways.

Following this step, it’s crucial for the patient to inhale deeply and hold their breath before coughing, allowing the air to be effectively trapped in the lungs and enhancing the force of the subsequent cough. However, emphasizing deep breaths is key to setting the stage for a productive cough.
