Its deficiency causes a decrease in the oxygen-carrying capacity of the blood which is anemia resulting in exertional dyspnoea or cyanosis. (plankhomeopathy.com)

Although those physiological variables are important to objectively determine the biological basis of dyspnoea, it is surprising that little attention, if any, has been given to the symptom per se as an auxiliary diagnostic tool. (ersjournals.com)
Dyspnea is a common symptom and, in most cases, can be effectively managed in the office by the family physician. (aafp.org)
1 - 4 Dyspnea is a common symptom and can be caused by many different conditions. (aafp.org)

He described progressive generalized weakness associated with worsening exertional dyspnea and chest tightness for the prior 2 months and an inability to manage the activities of daily living. (ochsnerjournal.org)

Most cases of dyspnea are due to cardiac or pulmonary disease, which is readily identified with a careful history and physical examination. (aafp.org)
Although other causes may contribute, the cardiac and pulmonary organ systems are most frequently involved in the etiology of dyspnea. (aafp.org)
The broad differential diagnosis of dyspnea contains four general categories: cardiac, pulmonary, mixed cardiac or pulmonary, and noncardiac or nonpulmonary ( Table 1 ) . (aafp.org)

An upward inflection in dyspnoea versus both V ′ E and WR exposes lung mechanical abnormalities. (ersjournals.com)

Conversely, sharp increases in dyspnoea as a function of WR but not V ′ E suggest that the underlying mechanism is proportional to inspiratory neural drive. (ersjournals.com)

Activity-related dyspnoea is a key cause of physical impairment in cardiovascular and respiratory diseases [ 1 ]. (ersjournals.com)
Hence ,Recognition of this anomaly is important, as it may mimic atherosclerotic coronary artery disease, where oxygen demand in myocardium normally supplied by it is taken over by RCA and such supply may not be sufficient during increased physical activity. (barnard.in)

Oxygen therapy in COPD has a number of physiologic, functional, and biologic effects, not all of which are completely understood. (rcjournal.com)
one RCT showed reduction in exertional dyspnoea and improvement in functional performance at 3 months. (herts.ac.uk)

We did not identify any studies that examined the effect of ambulatory oxygen on health-related quality of life, survival, costs or time to exacerbation or hospitalisation. (altmetric.com)

Conversely, if the mechanical constraints typical of respiratory diseases preclude the ventilatory pump to "respond" to an increased drive, dyspnoea is expected to increase at a faster rate than V ′ E [ 6 ]. (ersjournals.com)

The respiratory system attempts to maintain normal levels of oxygen and carbon dioxide. (ersjournals.com)
The carotid and aortic bodies and central chemoreceptors respond to the partial pressure of oxygen (PO 2 ), partial pressure of carbon dioxide (PCO 2 ) and pH of the blood and cerebrospinal fluid. (aafp.org)

The continuous oxygen therapy cohort had a greater reduction in hematocrit and pulmonary vascular resistance at 12 months. (rcjournal.com)

Additionally, myocardial hypertrophy results in increased wall tension and myocardial oxygen consumption. (medscape.com)
Furthermore, the hypertrophic LV requires a higher CPP to maintain myocardial oxygen supply in the setting of increased end-diastolic pressure. (medscape.com)

For example, in a patient with pulmonary edema, the accumulated fluid activates neural fibers in the alveolar interstitium and reflexively causes dyspnea. (aafp.org)

Muscle power was slightly reduced globally, and the patient developed increased dyspnea at a walking distance of only several meters. (ochsnerjournal.org)

In this context, the burden of exertional dyspnoea can be readily quantified by expressing its severity ( e.g. 0-10 Borg category-ratio scale) as a function of work rate (WR). (ersjournals.com)
In other words, the intensity and trajectory of dyspnoea as a function of V ′ E may not differ substantially from the pattern observed in normal subjects. (ersjournals.com)

Treatment may include antifibrotic drugs and oxygen therapy. (msdmanuals.com)

Work efficiency (WE) indicates the efficiency of overall oxygen consumption (VO2) during exercise. (mendeley.com)

Owing to the fact that such constraints further increase beyond a certain critical intensity [ 7 ], it is conceivable that they could be identified by a sudden upward inflection of dyspnoea against V ′ E . To the authors' knowledge, such theoretical constructs have not yet been put under scrutiny with the specific objective of discriminating cardiovascular versus respiratory disease as a cause of exertional dyspnoea.
