Respiratory Function in Healthy Taiwanese Infants: Tidal Breathing Analysis, Passive Mechanics, and Tidal Forced Expiration. [PDF]
PLoS ONE, 2015 Although infant lung function (ILF) testing is widely practiced in developed Western countries it is not typically performed in Eastern countries, and lung measurements are scarce for Asian infants.

Grouping Similar Seismocardiographic Signals Using Respiratory Information [PDF]
Signal Processing in Medicine and Biology (2017) 1-6, 2017 Seismocardiography (SCG) offers a potential non-invasive method for cardiac monitoring. Quantification of the effects of different physiological conditions on SCG can lead to enhanced understanding of SCG genesis, and may explain how some cardiac pathologies may affect SCG morphology.

Reference values for lung function tests: I. Static volumes [PDF]
, 1999 Static lung volume (LV) measurements have a number of clinical and research applications; however, no previous studies have provided reference values for such tests using a healthy sample of the adult Brazilian population.

Lung volumes and airway resistance in patients with a possible restrictive pattern on spirometry
Jornal Brasileiro de PneumologiaObjective: Many patients with proportional reductions in FVC and FEV1 on spirometry show no reduction in TLC. The aim of this study was to evaluate the role that measuring lung volumes and airway resistance plays in the correct classification of patients

SpiroMask: Measuring Lung Function Using Consumer-Grade Masks [PDF]
arXiv, 2022 According to the World Health Organisation (WHO), 235 million people suffer from respiratory illnesses and four million people die annually due to air pollution. Regular lung health monitoring can lead to prognoses about deteriorating lung health conditions.

Ventilation inhomogeneity in patients with cystic fibrosis measured by electrical impedance tomography [PDF]
, 2012 Objective: The distribution of ventilation within the lung is inhomogeneous. We hypothesized that the degree of inhomogeneity in patients with cystic fibrosis (CF) differs from that in healthy subjects.
