Weigh the mass of the syringe containing the exhaled air
and calculate the mass of exhaled air
by subtracting the mass of the syringe containing the exhaled air
from the mass of the vacuum syringe.
Carbon monoxide was measured in the exhaled air
of all the professionals who worked in the ICUs in order to ascertain tobacco use with greater reliability.
Given the all reduced effects of adsorbing typical gases of lung cancer on the resistance of Ti[O.sub.2], the working principle of the biosensors would be based on the reduced resistance after the detection of exhaled air
of possible lung cancer patients regardless of which kind of typical gas it is.
(1) cumulative dose of [sup.13]C methacetin recovered from the exhaled air
(% cumulative dose, %CD), defined as the percentage of the exhaled [sup.13]C[O.sub.2] relative to the amount of [sup.13]C methacetin that was administered.
In cold air there is not much water vapour but warm exhaled air
is almost completely saturated with water vapour from its passage over the warm surfaces of the lungs and airways.
Or perhaps they should take inspiration from a camel's nose, which uses heat-exchange membranes to extract water from exhaled air
, and in the process cools its brain.
The volume of exhaled air
can be regulated by changing travel of the piston.
Oksala, MD, PhD, DSc, of the Department of Surgery, School of Medicine, University of Tampere and Department of Vascular Surgery, Tampere University Hospital, Finland, said eNoses have been studied in various medical applications, including early detection of cancer, especially from exhaled air
This can be done with air-to-air heat exchangers, which exhale warm, but stale, air through the exchanger while inhaling outside, fresher air, which is warmed by the exhaled air
as it passes through the vanes of the exchanger.
pushed water out of the bottle.) Explain that the air in the bottle represents lung capacity.
, also referred to as exhaled breath, is therefore also suitable for analysis in biological monitoring.
