Effects of Forceful Breathing Maneuvers of Spirometry on Respiratory Impedance Measured by Oscillometry [PDF]

Tuberculosis and Respiratory Diseases
Background Deep inspiratory maneuvers can modify airway diameter, leading to shortterm fluctuations in respiratory impedance (Zrs). However, the impact of the forceful breathing maneuvers used in spirometry on Zrs has not been systematically investigated.

Effect of somatotypes on lung volumes, capacities and respiratory impedance: A pilot study [PDF]

Lung India
Background: The current morphological condition of an individual is described by a somatotype, which is a three-number scale. The endomorph, mesomorph and ectomorph components are presented in the same sequence, and each number corresponds to one of the ...

Time–Frequency Respiratory Impedance Maps Enable Within-Breath Deep Learning for Small Airway Dysfunction Identification [PDF]

Bioengineering
Small airway dysfunction (SAD) is an early functional abnormality associated with multiple chronic airway diseases. However, clinical assessment often relies on spirometry-based indices, which require forced maneuvers and are sensitive to subject effort,

Lung volume recruitment maneuvers and respiratory system mechanics in mechanically ventilated mice [PDF]

, 2009
The study aim was to establish how recruitment maneuvers (RMs) influence lung mechanics and to determine whether RMs produce lung injury. Healthy BALB/c mice were allocated to receive positive end-expiratory pressure (PEEP) at 2 or 6 cmH2O and volume ...
