Authors J W Reed 1 , C Elliott, E Thorsen. Affiliation 1 The relationship between total dynamic compliance (lung plus chest wall), functional residual capacity, and alveolar-arterial oxygen gradients (A-a DO 2) was studied in paralyzed dogs during constant-volume ventilation with pure oxygen.Rapid changes in functional residual capacity (FRC), produced by forced deflation of the lungs, were associated with a rapid fall in total compliance and rise Lung Compliance Add Pharm Action Registry Number CAS Type 1 Name NLM Classification # Previous Indexing Elasticity (1966-1967) Lung/physiology (1966-1967) See Also Respiratory Mechanics Consider Also Public MeSH Note 70 Online Note History Note 70(68) Entry Combination Heading Mapped to Frequency Note Source Lung Physiology and Obesity: Anesthetic Implications for Thoracic Procedures. Alessia Pedoto 1. This can cause further decrease in chest wall and lung compliance, as well as in all spirometric measures, starting from the immediate postoperative period and persisting for 6–8 weeks .

Describe the difference between static and dynamic compliance. List: · Graphs x 2 · Static compliance · Determinants of static compliance · Dynamic compliance · Difference between static and dynamic compliance: i.e. hysteresis These differences are statistically significant (p less than 0.001) and illustrate the influence of a progressive increase in lung stiffness (CL = 100.3 +/- 17.2 ml/cmH2O in group 1, CL = 45.0 +/- 6.3 ml/cmH2O in group 2, and CL = 28.6 +/- 8.9 ml/cmH2O in group 3) on transmission of airway pressure to the pleural space. With deep saturation diving a reduction in vital capacity caused by oxygen toxicity may be opposed by a training effect of respiratory muscles due to increased gas density and work of breathing. We measured lung and chest wall mechanics before and after a 28-day saturation dive to a pressure of 0.25 … A lung of high compliance expands to a greater extend than one of lower compliance when both are exposed to the same increase in transpulmonary pressure . Hyperinflation and tidal breathing towards the total lung capacity force the respiratory system to operate on the flatter part of the compliance curve where progressive pressure increases generate smaller incremental volume changes [ 17 ].

Physiology, Lung Compliance. Pulmonary compliance, a measure of the expansion of the lung, is critical to the proper function of the respiratory system. Lung compliance can be calculated by dividing volume by pressure. Factors affecting lung compliance include elasticity from the elastin in connective tissue and surface tension ….

The latter age difference may result from a loss of lung elastic recoil in the elderly or may be due totally to the age difference in chest wall compliance.

Happy hypoxemia (severe hypoxemia without dyspnea) can be generated by a combination of shunt physiology, preserved lung compliance, and lack of dead space. This may result from any lung disease which causes a limited amount of shunt, while preserving the remainder of the lung (e.g., lobar consolidation or atelectasis).

Elastance, also known as the elastic resistance is the reciprocal of compliance, i.e. the pressure change that is required to elicit a unit volume change.
