The Correlation Between Body Fat Percentage and Peak Expiratory Flow in Children Aged 10-12 Years at SD Negeri 8 Dauh Puri [PDF]

open access: yes, 2019
Background: The accumulation of fat decreases lung function. Peak expiratory flow is an indicator for assessing pulmonary function and can be used to identify the narrowing or obstruction of the airway. This study aimed to examine the correlation between

Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

open access: yes, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Low Frequency Forced Oscillation Lung Function Test Can Distinguish Dynamic Tissue Non-linearity in COPD Patients

open access: yesFrontiers in Physiology, 2019
This paper introduces the use of low frequencies forced oscillation technique (FOT) in the presence of breathing signal. The hypothesis tested is to evaluate the sensitivity of FOT to various degrees of obstruction in COPD patients. The measurements were

Entropy Analysis for the Evaluation of Respiratory Changes Due to Asbestos Exposure and Associated Smoking

open access: yesEntropy, 2019
Breathing is a complex rhythmic motor act, which is created by integrating different inputs to the respiratory centres. Analysing nonlinear fluctuations in breathing may provide clinically relevant information in patients with complex illnesses, such as ...

Acute effects of short term use of e-cigarettes on airways physiology and respiratory symptoms in smokers with and without airways obstructive diseases and in healthy non smokers

open access: yesTobacco Prevention and Cessation, 2017
Introduction Although the use of e-cigarettes is increasing worldwide, their short and long-term effects remain undefined. We aimed to study the acute effect of short-term use of e-cigarettes containing nicotine on lung function and respiratory symptoms ...

Electrical impedance tomography: Amplitudes of cardiac related impedance changes in the lung are highly position dependent. [PDF]

open access: yesPLoS ONE, 2017
Electrical impedance tomography (EIT) is used on the thorax to measure impedance changes due to the presence of air and blood in the lung. This experimental study was performed to investigate the effect of posture on cardiac and respiratory related ...
