Tips for correctly using a volumetric exerciser include having the patient breathe normally, inhale slowly and hold his breath long enough, states the National Institutes of Health's MedlinePlus. A volumetric exerciser keeps lungs healthy after a lung illness or surgery.
A patient should use a volumetric exerciser while sitting up. After forming a tight seal around the end with the mouth, the patient should exhale normally and inhale slowly. This teaches a patient how to take the slow, deep breaths necessary to prevent lung illnesses, notes the National Institutes of Health's MedlinePlus.
If a patient experiences dizziness while using the exerciser, he should remove the mouthpiece and take a few normal breaths before continuing to use the device. A patient with an abdominal or chest incision may need to hold a pillow against his stomach while inhaling to help ease discomfort. The patient should hold his breath for 3 to 5 seconds before exhaling, according to the National Institutes of Health's MedlinePlus.
