Temperature, humidity and mucus flow in the intubated trachea.
Mucus flow rates were measured in the intact trachea of anaesthetized dogs, using a radioactive tracer technique. Measurements were made before intubation, and after intubation at inspired air temperatures of 32, 37 and 42°C, with a constant inspired water vapour content of 33 mg/1.; and again at each temperature with a relative humidity of 75%. No significant difference in mucus flow rate was ...
متن کاملSymmetrical-waveform high-frequency oscillation increases artificial mucus flow without changing basal mucus transport in in vitro ovine trachea.
BACKGROUND The efficacy of symmetrical-waveform high-frequency oscillating (HFO) air flow for airway secretion clearance is controversial and debated in the literature. METHODS We conducted in vitro experiments with ovine tracheae to investigate the effects of symmetrical-waveform HFO on tracheal transport of artificial mucus. We mounted each trachea as an intact tube, with a 15(o) head-down ...
متن کاملMucus transportability: the bovine trachea and frog palate models compared.
For nearly 30 yrs, the mucus-depleted frog palate has been used to measure the ciliary transportability of respiratory and other mucus gels, but the data obtained from this amphibian digestive system may not be applicable to human airway mucociliary clearance. This study compared this model with the mucus-depleted bovine trachea, a mammalian respiratory system. Assessments were made of the repr...
متن کاملMucus secretion from individual submucosal glands of the ferret trachea.
Mucus secretion from individual tracheal glands in adult ferrets was studied with time-lapse optical imaging of mucus droplets under an oil layer. Density of functional glands (determined by responses to 1 muM carbachol) was 1.5 +/- 0.3 per mm(2) (n = 6). Secretion rates (in pl.min(-1).gland(-1)) were as follows: 4.1 +/- 0.7 basal (unstimulated; n = 27, 669 glands), 338 +/- 70 to 10 microM fors...
متن کاملthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
