Stimuli-responsive hydrogels have large deformability but—when applied as actuators, smart switch, and artificial muscles—suffer from low work density due to low deliverable forces (~2 kPa) and speed through the osmotic pressure–driven actuation. Inspired by the energy conversion mechanism of many creatures during jumping, we designed an elastic-driven strong contractile hydrogel through
In 1929 von Neergaard demonstrated that surface forces are responsible for a large part of the elastic recoil pressure of the lungs. 1 This was evidenced by recordings of elastic recoil during deflation of air- and liquid-filled lungs.
Because elastic recoil of the lung is the effective pressure driving maximal expiratory flow, an increase after surgery should improve flow proportionately at all lung volumes and secondarily 2016-09-20 · Transpulmonary pressure was calculated as airway minus pleural pressure. Lung pressure/volume curves of an isolated lung coincided with lung P/V curves in the complete model irrespective of chest wall stiffness. ΔEELV was equal to the size of the PEEP step divided by lung elastance (EL), ΔEELV = ΔPEEP/EL. Stimuli-responsive hydrogels have large deformability but—when applied as actuators, smart switch, and artificial muscles—suffer from low work density due to low deliverable forces (~2 kPa) and speed through the osmotic pressure–driven actuation. Inspired by the energy conversion mechanism of many creatures during jumping, we designed an elastic-driven strong contractile hydrogel through Lung elastic recoil was lower (B/A% z-score ≤ −1.64) in five out of 18 subjects and compliance was higher (K z-score ≥1.64) than normal in nine out of 18 subjects. Elastic recoil pressure at functional residual capacity was low at 1.4 (0.8–3.6) cmH 2 O. this! High compliance = less elastic recoil; low compliance = more elastic recoil.
2018-07-23 In the present study, lung elastic recoil at control end inspiration was measured in normal subjects in a volume displacement plethysmograph before and after voluntary increases in mean lung volume, which were achieved by one tidal volume increase in functional residual capacity (FRC) with constant tidal volume and by doubling tidal volume with constant FRC. This because of the increased elastic recoil pressure of the lungs; the FRC volume ends up being lower because that is where the chest wall recoil and the lung elastic recoil find their new equilibrium. Lastly, let's see what happens if the chest wall becomes more resistant: Recoil pressure is the pressure that is exerted on the two sides of the elastic structures. To attain a hollow elastic construction for moving from its resting volume, one side of the assembly must be unprotected to an advanced pressure than the other. A: alveolar pressure-volume (PV) curves for an alveolus without surfactant and tissue elastic properties.B: simulations of the alveolar PV curve with the tissue elastic properties and a constant γ of 73 mN/m.The radius of the rigid ring a varies between 0, 75, 100, and 150 μm.
elastance: [ e-las´tans ] the quality of recoiling on removal of pressure without disruption, or an expression of the measure of the ability to do so in terms of unit of volume change per unit of pressure change; it is the reciprocal of compliance.
