Lung function testing is performed using spirometry, body plethysmography (lung volumes, body box) and single breath diffusion (gas transfer, transfer factor (TLCO)) at specified visits.
Lung ultrasound was used to assess for the presence of EVLW, and a single-breath gas transfer capacity of the lung (TLCO) was measured.
We determined the diffusion capacity of carbon monoxide (DLCO) using a single-breath technique (transfer test; PK Morgan Ltd., Chatham, Kent, UK) (Cotes et al. 1997; Forster et al. 1954).
Good lung capacity equals deeper breaths, efficient oxygen transfer and, ultimately, improved running performance, and your posture has a direct impact on your ability to do this well.
Finding Patrick in moderate distress, "with a rapid respiratory rate and grunting, with lots of effort going into each breath," he advised transferring the infant to Boston.
3 ml of 0.2 micron filtered exhaled breath sample was transferred into a 10ml septa-sealed vial containing helium gas, and analyzed by gas isotope ratio mass spectrometry using a DeltaplusXL instrument for 13C enrichment in headspace CO2.
The PFTs (spirometry, body plethysmography and single-breath carbon monoxide transfer) using routine techniques had been performed for clinical purposes.
The condensed breath was then transferred into a microtube and stored at −20°C and then −80°C until use.
Wireless transfer of breath-by-breath data to a laptop computer allowed real-time monitoring.
