Hydrapep is a TGA listed bubble PEP- a device formerly ‘home-made’ from bottles & tubing – used by physiotherapists to alleviate respiratory problems. It is an effective treatment for productive coughs. Blowing bubbles in the water creates positive pressure in the airways, which helps to improve movement of air in and out of the lungs, prevent airway collapse, & dislodge secretions. Hydrapep is easy to clean, & is designed to be used easily by both the young and elderly. It can be used as a stand-alone treatment or in conjunction with traditional chest physiotherapy. Its safety feature allows therapists to safely ascertain whether a patient can use it correctly, minimising the risk of aspiration.
