However, the 10% tea tree oil cream doesn't seem to cure the infection. A stronger tea tree oil solution (25% or 50%) is needed for that. Application of 25% or 50% tea tree oil solution appears to both relieve symptoms and clear up the infection in about half of people who try it for 4 weeks.
Vital capacity (VC): the volume change of the lung between a full inspiration and a maximal expiration. 1. The maneuver is performed rather slowly. The vital capacity is assessed during an inspiratory maneuver. Starting from end-tidal volume the subject expires maximally and subsequently makes a full inspiration.
vital capacity VC; the volume of gas that can be expelled from the lungs from a position of full inspiration, with no limit to duration of inspiration; equal to inspiratory capacity plus expiratory reserve volume.Spirometry (meaning the measuring of breath) is the most common of the pulmonary function tests (PFTs), measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled.
