What should you know about the Coach 2 spirometer?

An incentive spirometer provides visual feedback as you inhale. The goal is a controlled, deeper breath rather than a forceful blow. It may be recommended after surgery, during reduced mobility or when a clinician wants to support regular lung expansion. It is different from diagnostic spirometry, which measures airflow to assess lung function. The device does not replace prescribed inhalers, oxygen, antibiotics or other treatment.

Sit upright and keep the device level. Seal your lips around the mouthpiece, breathe in slowly and deeply so the indicator rises toward the target set by your care team, then hold the breath briefly if instructed. Remove the mouthpiece and breathe out normally. Rest if you become dizzy, and follow the schedule given by your clinician. Clean the mouthpiece according to the product instructions and do not share it.

Stop and seek medical advice for chest pain, severe breathlessness, fainting, blue lips, coughing blood or dizziness that does not settle with rest. Contact your care team if pain prevents deep breathing, you cannot use the device as taught, or your breathing is worsening. These symptoms need assessment rather than repeated practice alone.

Ask what target and schedule are right for you, whether you should use the device after pain relief, and how to clean it. Clarify whether your device is for breathing exercises or whether you also need formal [spirometry](/treatments/diagnostics-and-screening/spirometry/).
