*  Respiratory compliance but not gas exchange correlates with changes in lung aeration after a recruitment maneuver: an...
The plateau pressure and static lung compliance correlated equally with nonaerated and poorly aerated lung volumes. It appears that in lung injury, VPOOR and VNON are the main determinants in overall lung compliance. Following the argument of Barnas et al. [32] that the elastance (E) of the rib cage compartment is parallel to the elastance of the diaphragm-abdomen compartment, the elastances of the differently aerated lung compartments could behave similarly and thus be described by the equation 1/ELUNG = k1/EHYP + k2/ENORM + k3/EPOOR + k4/ENON, where the constants k1-4 depend on their fraction of total lung volume. Thus in healthy lungs, EL is mainly dependent on ENORM, because it has the highest fraction of lung volume. But with increasing fractions of EPOOR and ENON (with much higher values than ENORM) they will become ...
*  Randomised controlled trial of respiratory system compliance measurements in mechanically ventilated neonates | ADC Fetal &...
In this study the introduction of measurements of static respiratory system compliance into clinical practice had no major effect on any of the primary outcome measures. This pragmatic estimate of the potential impact of respiratory function testing on major hospital outcomes does not exclude moderate benefit from this intervention, as the sample size only yielded adequate power to show a substantial difference in adverse outcomes. Until more powerful trials are conducted, caution is warranted in the rapidity with which respiratory function tests are being incorporated into routine care.. In the era of antenatal steroids and replacement surfactant a smaller proportion of infants present serious problems with ventilation than before, and it may be that by considering all ventilated infants the power of the study was blunted by the number of infants who were destined to have good outcomes. Secondary analysis suggests that there may be important potential benefits in terms of reduced duration ...

*  Ventricular pressure-volume curve indices change with end-diastolic pressure. | Circulation Research
Many indices have been proposed to describee the diastolic pressure-volume curve mathematically and permit quantification of the elastic properties of the myocardium itself in hopes that changes in the muscle caused by disease would b.e reflected in the diastolic pressure-volume curve. To date, none of the proposed indices has been shown convincingly to discriminate one group of patients from another. While this situation in part arises from the relatively large amount of noise introduced by the technical difficulties of measuring synchronous pressures and volumes during diastole in man, ther is a more fundamental difficulty. In practice, one can measure only a short segment of the entire pressure-volume curve, and the values of all diastolic pressure-volume curve parameters investigated change significantly when one uses different segments of the same pressure-volume curve to compute them. These results were derived from relatively noise-free pressure-volume curves obtained by filling nine ...

*  Chest wall compliance: Calculation
Chest wall compliance is the opposite of elasticity, and elasticity is the tendency of lung tissue to return to its original (or relaxed) position after an applied force has been removed. Compliance is essentially the ability of the lung tissue to "absorb" the same applied force, which generally results from a change in intrathoracic pressure.. Chest wall compliance can be calculated by this formula:. Compliance = Δ V / Δ P. Where change in volume is in liters and change in pressure is in cm H20.. There are two different types of compliance: static and dynamic. Static compliance is a measured during plateau (rather than peak inspiratory) pressure. PEEP should be subtracted from plateau inspiratory pressure in making this calculation. Because the pressure-volume curve (see below) is not linear during inspiration and expiration due to changes in the lung ...

A pressure-volume diagram with isocompliance lines allows quick, accurate volume setting of the piston-driven infant ventilator Bourns LS. A line parallel with the machine compliance line and an intercept on the ordinate equal to the tidal volume, serves as a guideline for initial volume setting and subsequent adaptation according to the patient's lung compliance. This diagram is particularly useful when the lung compliance is low; changes consistently during controlled ventilation ...

Second, because some of the ventilators were operated at constant inspiratory flow and others were operated with variable flow and because nonlinear resistances were used in the lung models, the ventilators were actually subjected to different resistive loads (see Fig. 1). The point is that when comparing the performance of different devices, they should all be subjected to the same experimental conditions. Failing that, some of the variability of the outcome variables might be attributed to the experimental conditions rather than variability in device performance.. Third, the authors observed that one of the ventilators was unable to deliver an accurate VT of 300 mL in the normal condition. This particular ventilator could not deliver 300 mL because it delivers only pressure control modes, and it is designed to deliver no less than 5 cm H2O inspiratory pressure. Hence, the minimum VT it could be expected to deliver to a lung model with a compliance of 100 ...

Introduction. Explain how the digestive, cardiovascular and respiratory systems are interrelated There are many systems within the body; all the systems have to work with one another in order to keep the body going and functioning as it should. The respiratory system, cardiovascular system and the respiratory systems are one of the few systems that are interrelated within the body and that work together in order to keep the body functioning. The respiratory and cardiovascular system both interrelate within the complex system of the human body, as firstly the oxygen that enters the body is inhaled and enters the respiratory system. This oxygen then travels through the trachea into the lungs following on to the alveoli and diffusing through the alveolar wall. ...read more. Middle. Both systems also work together by providing nutrients in order for aerobic respiration to be carried out. The first part of the aerobic respiration is aided by both these systems as oxygen is inhaled by the ...
