This AeroChamber Plus Flow-Vu spacer is designed to help patients take their inhaled medications more effectively. It works by creating a reservoir of medication, which allows the patient to inhale the medication more slowly and deeply. This can help to improve the delivery of medication to the lungs and reduce the risk of side effects. The Flow-Vu chamber has a clear window that shows when the medication is fully inhaled, making it easy for patients to use. This spacer is suitable for use with most inhalers. The spacer has been used but is in excellent condition, with no damage or cracks. It has been thoroughly cleaned and is ready to use. This is a great option for anyone who wants to get the most out of their inhaler medication.
