What should you know about a flow-oriented incentive spirometer?

The mouthpiece connects to a clear chamber containing a visual indicator. When you breathe in through the device, the indicator rises or moves in response to the speed of the airflow. The goal is usually a controlled inhalation rather than a forceful gasp. The device encourages the lungs to expand and can help you notice whether your breath is steady.

It is different from spirometry, a breathing test that records measurements for a clinician. An incentive spirometer is commonly used as a breathing exercise, while the purpose and instructions depend on why it was given to you.

Sit upright if possible and relax your shoulders. Seal your lips around the mouthpiece, then inhale slowly and deeply through it. Hold the breath briefly if your care team has advised this, remove the mouthpiece, and breathe out normally. Rest between attempts if you feel light-headed, tired, or uncomfortable. Follow the schedule given by your clinician, and keep the mouthpiece clean according to the manufacturer’s instructions.

Coughing gently after a few breaths may help clear mucus, but do not force a painful cough. If your incision hurts, support it as instructed by your surgical team. Ask for a demonstration if the indicator does not move or you are unsure whether air is passing through the mouthpiece.

Stop and seek urgent medical help for severe or sudden breathlessness, chest pain, blue or grey lips, fainting, or confusion. Contact your healthcare team promptly for worsening breathing, a new fever, coughing blood, or increasing pain after a procedure. These symptoms need assessment rather than repeated attempts with the device.

Ask how often to use the spirometer, what target movement is appropriate for you, and whether you should pause if coughing or pain occurs. Clarify how to clean it, when to stop using it, and who to contact if your breathing becomes harder.
