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.
Total lung capacity refers to the maximum amount of air a personâs lungs can hold, about four to six liters (4000 to 6000 cm3) for the average human. Only a third of this capacity is used during normal activity, but this fraction increases during strenuous activity when the body requires more oxygen. On average, males have a 20-25% higher capacity than females, and tall individuals have a greater capacity than short people. The human lungs enable respiration.
