Evaluation of transcutaneous CO2 responses following acute changes in PaCO2 in healthy subjects.

14 Dec 2009 BACKGROUND AND OBJECTIVE: Transcutaneous blood gas-monitoring systems with miniaturized SpO(2) (peripheral blood oxygen saturation)/PCO(2) combined sensors (TOSCATM) have been widely used. There are no reports of the inter- and intra-individual ... Read more...

Exhaled nitric oxide levels in asthma: Personal best versus reference values.

17 Sep 2009 BACKGROUND: Factors affecting the fraction of nitric oxide in exhaled air (FE(NO)) are multiple. Interpreting values when assessing airways disease may be problematic. Clinically optimum levels have not been defined. OBJECTIVES: We aimed to ... Read more...

The mechanism of breath aerosol formation.

30 Aug 2009 BACKGROUND: Aerosol production during normal breathing is often attributed to turbulence in the respiratory tract. That mechanism is not consistent with a high degree of asymmetry between aerosol production during inhalation and exhalation. The ... Read more...
