IMT training aims to decrease which symptom?

• A. Dyspnea
• B. Secretions
• C. Tachypnea
• D. Hypoxemia

Answer: (A)

IMT strengthens the muscles used to inhale, helping breathing require less effort. That reduced work of breathing lowers the sensation of breathlessness, so dyspnea is the symptom IMT is designed to improve. IMT doesn’t directly remove secretions or fix gas exchange; those are addressed with airway clearance and oxygenation/ventilation strategies, and tachypnea may improve only as a downstream effect of easier breathing.
