RSV in severe cases may be necessary to provide intravenous (IV) fluids and humidified oxygen. Mechanical ventilation is a breathing machine to ease breathing. A nebulized bronchodilator such as albuterol (ProAir HFA, Proventil-HFA, Ventolin HFA) may be used to relieve wheezing. This medication opens air passages in the lungs. Nebulized means it's administered as a fine mist that you breathe in. Occasionally, a nebulized form of ribavirin (Virazole), an antiviral agent, may be used.
