Significance: Gasotransmitters are small gas molecules that are endogenously generated
and have well-defined physiological functions. The most well-defined gasotransmitters …

Hydrogen cyanide (HCN) is a well-known toxic compound in many fields. The trace amount
of endogenous HCN in human exhalation has been associated with the presence of …

The influence of breath sampling on exhaled carbon monoxide (eCO) and related
pulmonary gas exchange parameters is investigated in a study with 32 healthy non …

Real-time breath gas analysis coupled to gas exchange modeling is emerging as promising
strategy to enhance the information gained from breath tests. It is shown for exhaled breath …

The respiratory system is one of the complicated systems in the human body. In this paper,
the mathematical model for the respiratory system was proposed based on the electro …

The fraction of exhaled nitric oxide (FE NO) is an important biomarker for the diagnosis and
management of asthma and other pulmonary diseases associated with airway inflammation …

The measure of hemolysis in humans is clinically important. Here we describe methods
using a gas chromatograph equipped with a reduction gas detector to detect the human …

Blood flow and ventilatory flow strongly influence the concentrations of volatile organic
compounds (VOCs) in exhaled breath. The physicochemical properties of a compound (eg …

Optical spectroscopy is widely used for quantitative detection of small molecules in complex
gas matrices. Employing a laser as a light source enables highly sensitive, selective, and …

We examine the functional form of the slip correction factor C (Π), where Π is a
dimensionless group to be determined, for simple (monoatomic, diatomic, and triatomic) gas …
