| LLL | left lower [eye]lid; left liver lobe; left lower leg; left lower lobe |
| LLLE | lower lid left eye |
| LLRE | lower lid right eye |
| lid reflex | A contraction of the eyelids when the cornea is lightly touched with a camel-hair pencil. Synonym: lid reflex. Reflection of light from the surface of the cornea. (05 Mar 2000) |
|---|---|
| lower lid | The inferior, smaller and less mobile of the two eyelids; a check ligament from the inferior rectus muscle extends into it, pulling the lid inferiorly when the gaze is directed downward. Synonym: palpebra inferior, lower lid. (05 Mar 2000) |
| bladder compliance | Relationship of volume to pressure; can be calculated from a cytometrogram's pressure volume curve. Synonym: compliance of bladder. (05 Mar 2000) |
| ventilatory compliance | The sum of dynamic compliance of the lung and thoracic compliance. (05 Mar 2000) |
| patient compliance | Voluntary cooperation of the patient in following a prescribed regimen. (12 Dec 1998) |
| compliance | A physical quality of yielding to pressure or force without disruption, or an expression of the measure of the ability to do so, as an expression of the distensibility of an air- or fluid-filled organ, e.g., the lung (lung compliance) or the bladder, in terms of unit of volume change per unit of pressure change. (12 Dec 1998) |
| compliance of bladder | Relationship of volume to pressure; can be calculated from a cytometrogram's pressure volume curve. Synonym: compliance of bladder. (05 Mar 2000) |
| compliance of heart | The reciprocal of passive or diastolic stiffness of the ventricle of the heart, most commonly of the left ventricle; one may distinguish between compliance of the muscle and compliance of the supportive structures, although ordinarily both are considered together (chamber compliance); a hypertrophied or scarred heart will manifest a stiff wall, i.e., decreased compliance. (05 Mar 2000) |
| specific compliance | The compliance of a structure divided by its initial volume, more specifically for the lungs, the compliance divided by the functional residual capacity. (05 Mar 2000) |
| static compliance | The value obtained when compliance is measured at true equilibrium, i.e., in the absence of any motion. (05 Mar 2000) |
| detrusor compliance | Change in volume of bladder for a given change in pressure. (05 Mar 2000) |
| dynamic compliance of lung | The value obtained when lung compliance is estimated during breathing by dividing the tidal volume by the difference in instantaneous transpulmonary pressures at the ends of the respiratory excursions, when flow in the airway is momentarily zero; this value deviates markedly from static compliance in patients in whom resistances and compliances are not uniform throughout the lung (i.e., uneven time constants). (05 Mar 2000) |
| thoracic compliance | That portion of total ventilatory compliance ascribable to compliance of the thoracic cage. (05 Mar 2000) |
| lung compliance | The pulmonary volume change per unit pressure change. While clearly not a complete description of the pressure-volume properties of the lung, it is nevertheless useful in practice as a measure of the comparative stiffness of the lung. The stiffer the lung, the less the compliance. Compliance is reduced by diseases which cause an accumulation of fibrous tissue in the lung or by oedema in the alveolar spaces. It is increased in pulmonary emphysema and also with age, probably because of alterations in the elastic tissue in both cases. (12 Dec 1998) |
