Example sentences for: tef
How can you use “tef” in a sentence? Here are some example sentences to help you improve your vocabulary:
The ratio 25/PT will be influenced by the values of TEF25 as well as PTEF.
25/PT = the ratio of tidal expiratory flow at 25% of the remaining tidal volume to peak tidal expiratory flow; PTEF = peak tidal expiratory flow; RSV = respiratory syncytial virus; TBFV = tidal breathing flow volume; TEF10 = tidal expiratory flow at 10% of the remaining tidal volume; TEF25 = tidal expiratory flow at 25% of the remaining tidal volume; TEF50 = tidal expiratory flow at 50% of the remaining tidal volume; t PTEF / t E = the fraction of exhaled time to achieve peak tidal expiratory flow to total expiratory time; V PTEF / V E = the fraction of exhaled volume to achieve peak tidal expiratory flow to total expiratory tidal volume.
Both TEF10 and 25/PT significantly decreased after albuterol administration ( P < 0.05).
This present study in infants with mild bronchiolitis due to RSV demonstrates that nebulized albuterol does not improve V PTEF / V E and t PTEF / t E , but can decrease TEF10 and 25/PT.
The behavior of V PTEF / V E mainly parallels that of t PTEF / t E . The same mechanisms responsible for determining t PTEF / t E may be operative in determining V PTEF / V E . The role of several measured tidal flows (TEF50, TEF25, TEF10) and ratios (25/PT) in the evaluation of pulmonary function is mostly unknown.
