Pulmonary Compliance Is Reduced in Which of the Following

By Ra_Angela135 10 May, 2022 Post a Comment

The compliance of a system is defined as the change in volume that occurs per unit change in the pressure of the system. In the case of atelectasis pulmonary compliance decreases due to a decrease in the volume of the lung and requires higher pressure to inflate the alveoli.

All of the following are true of intrinsic restrictive lung disease EXCEPT.

. In layman terms compliance is the ease with which an elastic structure stretches. Reduced gas exchange due to deterioration of pulmonary vascular system. Reduced Dynamic compliance without change in static compliance indicates Ted airway resistance Obstruction Bronchospasm Allergic Asthma Collapse of small airways etc.

Pulmonary compliance C is the total compliance of. Pulmonary surfactant increases compliance by decreasing the surface tension of water. Lung compliance may be markedly reduced as a result of alveolar atelectasis due to impaired pulmonary surfactant activity as well as pulmonary edema caused by increased permeability see Chapter 21.

Pulmonary fibrosis is a restrictive lung disease. Seen with scarring or fibrosis of lungs c. Valvular Restrictive Obstructive Apnea.

A decrease in lung compliance and in FRC is the major pathophysiologic abnormality in patients with restrictive pulmonary disease processes such as pulmonary fibrosis interstitial pneumonias sarcoidosis bronchiolitis obliterans organizing pneumonia and those with ALI and ARDS. Lung compliance is an important measurement in respiratory physiology. 6 Ventilation-perfusion alterations also.

Black lung causes pulmonary fibrosis due to the inhalation of large amounts of carbon dust. Filling with fluid removes the Air-fluid interface that normally maintains Surface Tension. Lung compliance participates in the lung-chest wall system by opposing the outward pull of chest wall compliance.

Compliance can be thought of as stretchability or ease of expansion Which two factors affect compliance. The greater the lung compliance the harder or easier it is to expand the lungs. Reduced static compliance is usually also associated with a decreased dynamic compliance due to associated airway resistance.

Easier high compliance means large volume change per unit of pressure change. Which of the following is true of lung measurements. Despite the conflicting findings several studies have reported that chest wall and lung compliance are both reduced in obesity 6 7 8 19.

Lung compliance is due to. 361314 Pulmonary edema can occur within minutes of smoke inhalation although it typically develops over a period of up to 24 hours. Emphysema COPD may be associated with an increase in pulmonary compliance due to the loss of alveolar and elastic tissue.

Which of the following is TRUE for a pulmonary fibrosis patient. Select All the correct answers A Forced expiration is reduced B Vital capacity is reduced Forced inspiration is normal Lung compliance is reduced Vital capacity is normal Blood flow is greatest at the of the lungs and perfusion is greatest at the of. This is secondary to alveolar collapse and a decrease in the volume of lung available for ventilation and.

Thus the lungs fill at less pressure with fluid than with air. An individual with a pneumothorax would have air in the pleural space Lung compliance. Obtaining a compliance curve along with oximetry and arterial gas analysis is one useful method in ICU monitoring.

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 which is decreased by surfactant production. Which of the following does not diminish lung compliance.

Causes an increase in compliance e production is reduced after a prolonged reduction in pulmonary blood flow 19 A pressure-volume curve can be used for measuring. FEV1FVC are greater than 70. Compliance is therefore basically a measurement of the elastic resistance of a system.

Increased force required to fill and empty the lungs. A Fowlers method measures physiological dead space. It is an inflammatory process.

Reduced lung compliance. A factors that block the bronchi B factors that impair the flexibility of the thoracic cage C factors that reduce the natural resilience of the lungs D factors that decrease the surface tension of the fluid film of the alveoli December 8 2020 in Feeds by admin. Seen with scarring or fibrosis of lungs c.

Decrease elasticity fibrosis. It is very likely that the reduction in lung volumes induced by the obese state is a major contributor to the decreased compliance of the lungs whether tissue mechanics are also affected is not clear. Involve decreased lung compliance b.

It is a problem with the parenchyma of the lung. Low lung compliance can be the result of interstitial lung diseases resulting from the inhalation of particulate substances such as asbestos asbestosis and silicon silicosis. FVC is dramatically reduced d.

Fibrosis is associated with a decrease in pulmonary compliance. Which type of lung disorder decreases pulmonary compliance and thereby decreases vital capacity. Which of the following are true concerning restrictive lung diseases.

FVC is dramatically reduced d. The lungs become much more compliant. Involve decreased lung compliance b.

Filling the lungs with fluid serves to reduce the Critical Opening pressure of the alveoli. Pleural membranes envelop organs within the thoracic cavity. Elasticity of lung tissue.

A decrease in pulmonary compliance and FRC is seen in the patient with acute lung injury Pa o 2 F io 2 ratio 200-300 or ARDS Pa o 2 F io 2 ratio 200. Compliance is the ability of lungs and pleural cavity to expand and.
