The Difference Between Obstructive and Restrictive Lung Disease

Restrictive lung disease RLD is highly prevalent and frequently disabling and is caused by a myriad of both pulmonary and extrapulmonary conditions. Diagnosis therefore requires the use of less commonly available lung volume tests. Because of the difficulty in diagnosis and variety of etiologies, the clinical impact of RLD is not well understood. Patients with RLD are thought to be at risk for exaggerated postoperative pulmonary complications, although the degree of risk has not been well studied.

Underlying restrictive deficits may be worsened by perioperative atelectasis, loss of inspiratory muscle tone during anesthesia, pulmonary edema, or postoperative pneumonia.

Causes of restrictive lung disease [ 1 , 7 ]. There are no evidence-based recommendations for the preoperative evaluation of patients with RLD. The management of patients with RLD depends upon the underlying etiology. For example, obesity may also be associated with sleep-disordered breathing and should be evaluated as such Chap. Other diseases, such as sarcoidosis and hypersensitivity pneumonitis, can have concomitant airway hyperreactivity and should be treated similarly to chronic obstructive pulmonary disease Chap.

As with all patients with pulmonary disease, evaluation should include a detailed history of functional status and other risk factors for postoperative pulmonary complications Chap.

Consider an arterial blood gas, as this may be useful in estimating perioperative oxygenation and ventilation needs [ 7 , 10 ]. A chest X-ray is only useful in patients with acute dyspnea or if comparison studies are available to monitor for progression of disease [ 7 , 10 ].

Spirometry is not useful unless concomitant undiagnosed obstruction is suspected [ 8 ]. The symptoms of RLD are nonspecific and patients generally present with dyspnea and cough [ 1 ]. A careful history should assess for mobility, dyspnea on exertion, and other markers of fitness [ 9 ]. Chest radiographs are generally only useful for evaluating acute dyspnea. CT scans are only indicated if tracheal compression or other pathologic conditions are suspected [ 7 , 10 ]. Spirometry is useful as an initial assessment of lung function, but more detailed PFTs, including lung volumes and DLCO, are necessary to diagnose restriction and can give further insight as to the underlying cause [ 2 , 3 , 5 ].

Consider an arterial blood gas in patients with O2 dependence or severe dyspnea as this may help predict perioperative oxygenation and ventilation [ 7 , 10 ]. Recommendations are based on the underlying etiology of disease and a pulmonary consult is warranted in patients with severe respiratory compromise.

Management should focus on preventing atelectasis, pulmonary edema, postoperative pneumonia, and muscle weakness as these can worsen underlying restrictive deficits [ 7 ]. Lung expansion techniques may prevent atelectasis and are recommended by the ACP. Data suggest they are superior to no prophylaxis in preventing postoperative pulmonary complications in all patients undergoing abdominal surgery, although no modality of expansion showed clear superiority Chap. As with all pulmonary diseases, maintenance of adequate nutrition and selective use of nasogastric decompression after abdominal surgery are important in preventing complications [ 8 , 10 ].

Prevalence and factors associated with obstructive and restrictive lung function in people with chronic kidney disease CKD is unknown. In a multivariable Cox model, age HR, 1. In a representative sample of US adults, impaired lung function is common in those with and without CKD.

Doctors classify lung disease as either obstructive or restrictive. Those with restrictive lung disease experience difficulty fully expanding their lungs. Obstructive and restrictive lung disease share one main symptom—shortness of breath with any sort of physical exertion. Some common conditions related to obstructive lung disease include:. Obstructive lung disease makes breathing especially harder during increased activity or exertion.

How to recognize and treat restrictive lung disease

In these cases, a greater pressure P than normal is required to give the same increase in volume V. Common causes of decreased lung compliance are pulmonary fibrosis, pneumonia and pulmonary edema. In an obstructive lung disease , airway obstruction causes an increase in resistance. During normal breathing, the pressure volume relationship is no different from in a normal lung. However, when breathing rapidly, greater pressure is needed to overcome the resistance to flow, and the volume of each breath gets smaller.

Experiment HS Restrictive and Obstructive Airway Diseases. This lab was written in Restrictive lung diseases are chronic disorders that cause a decrease in the ability to expand the lung in the Set Up pdf document. Make sure to make.


Restrictive lung disease refers to a group of lung diseases that prevent the lungs from fully expanding with air. This restriction makes breathing difficult. Many forms of restrictive lung disease are progressive, getting worse over time. However, some causes of restrictive lung disease can be reversed.

As sleep centers receive increasingly sick patients that have much more than Obstructive Sleep Apnea OSA , it becomes even more essential for sleep technologists to gain improved knowledge of their patients and their illnesses. This includes distinguishing between various lung conditions, such as obstructive lung disease and restrictive lung disease. On the other hand, individuals with restrictive lung diseases have a difficult time fully expanding their lungs. Here, you'll learn about each, including their causes, symptoms, and how they're diagnosed and treated.
