Imposing a single frequency on normal tidal breathing may identify differences occurring during different stages of respiration, including for example at zero-flow (end-expiration and end-inspiration). We assessed the feasibility of using this … WebBACKGROUND--Measurement of the carbon monoxide transfer factor (TLCO) has traditionally been performed using the single breath method but recently the intrabreath method has been developed.
