The Vios® Aerosol Delivery System is designed from PARI's long legacy of clinically proven products used to treat Asthma, COPD or other respiratory conditions. This bundle consists of two important components: a Vios® compact compressor and a PARI LC Sprint nebulizer. The PARI Vios® has all the features you've come to know from the PARI ProNeb Ultra II. The term Vios® was inspired by the Latin and Greek words for "Life" (Vita + Bios = Vios®). The Vios® compact nebulizer delivers consistent particle size and fast treatments that result in a targeted delivery to the lungs. The average treatment time is 5 minutes per 2.5 ml of medication for the LC Sprint nebulizer. The small portable design of this product and the included carrying case that can carry all your accessories allows you to take the whole system wherever you need to go, increasing its usability.
