Example sentences for: ptef

How can you use “ptef” in a sentence? Here are some example sentences to help you improve your vocabulary:

Both t PTEF and t E will influence the final value of the ratio t PTEF / t E . In a patient with airway obstruction, slow exhalation secondary to an increased expiration time constant will increase t E . In addition, active breaking is diminished, leading to decreased t PTEF . Both these mechanisms result in a low t PTEF / t E value in a patient with airway obstruction.
Morris and Lane [ 8] demonstrated that, in older children and adults, V PTEF / V E and t PTEF / t E values from TBFV loops correlate well with specific airway conductance, with forced expiratory volume in the first second, and with the ratio of forced expiratory volume in the first second to the forced vital capacity.
These included the ratio of expiratory time to reach PTEF to the total expiratory time as a primary outcome measure, the tidal volume ( V T ), PTEF, TEF10, TEF25 and TEF50, and 25/PT as other pulmonary function tests of interest.
Increased effort during exhalation can theoretically lead to an increase in PTEF and, by dynamic compression of smaller airways, to a decrease in TEF25; this leads to a decrease in 25/PT.
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.
