Tidal volume: that volume of air moved into or out of the lungs during quiet breathing (VT indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.) FRC: Functional residual capacity: the volume in the lungs at the end-expiratory position: RV/TLC%
A government experiment to test ventilatory threshold was held between November and December 2004. Subjects included 32 physically active males (age: 22.3; TV: 180.5; TM: 75.5 kg; VO2max: 57.1 mL/kg/min) encountered a continuous test of increasing loads on a treadmill, cardiorespiratory and other variables were observed using ECG (recording of ...
[citation needed] The compression also causes a decreased total lung capacity (TLC) by 5% [9] and decreased expiratory reserve volume by 20%. [9] Tidal volume increases by 30–40%, from 0.5 to 0.7 litres, [9] and minute ventilation by 30–40% [9] [10] giving an increase in pulmonary ventilation. This is necessary to meet the increased oxygen ...

The original classification as VT 2.09 refers to the general type of vehicle (VT = Verbrennungstriebwagen = railcar with internal combustion engine), the power output (approximately 1/100 of the engine power, measured in PS) and the top speed (approximately 1/10 of the value in km/h). The trailers were numbered as VB 2.08, the driving trailers ...
From St. Johnsbury, the Roosevelt Highway turned southeast toward Portland along modern VT 18 while US 2 continued east along former Route 15 to Bangor. [9] No changes were made to US 2 in the final system plan approved on November 11, 1926. [4] US 2 was relocated onto its modern alignment along the original Roosevelt Highway route between ...
Ventricular tachycardia (V-tach or VT) is a cardiovascular disorder in which fast heart rate occurs in the ventricles of the heart. [3] Although a few seconds of VT may not result in permanent problems, longer periods are dangerous; and multiple episodes over a short period of time are referred to as an electrical storm.
Vermont Route 9 (VT 9) is a state highway in the U.S. state of Vermont.The highway runs 46.957 miles (75.570 km) from the New York state line in Bennington, where it continues west as New York State Route 7 (NY 7), to the New Hampshire state line at the Connecticut River in Brattleboro, where the highway continues as New Hampshire Route 9 (NH 9).
