general examination showed an obese patient (body mass index 36.7) on 2 l of oxygen by nasal cannula. a grade 2/6 systolic heart murmur was present along both sides of the sternum. there was no peripheral edema. there was mild, symmetric weakness of the deltoid, biceps, and iliopsoas muscles bilaterally. muscle stretch reflexes were normal, plantar responses were flexor, and muscle tone was normal. she was able to rise from sitting without using her arms. access for 1 day (from the computer you are currently using) is us$ 39.00. pay-per-view content is for the use of the payee only, and content may not be further distributed by print or electronic means. distributing copies (electronic or otherwise) of the article is not allowed.

pulmonary function testing revealed the following: forced expiratory volume in 1 second (fev1), 1.88 l (68%); forced vital capacity (fvc), 2.42 l (66%); and fev1/fvc, 78%. his total lung capacity was 5.37 l (87%), and the diffusing capacity of the lung for carbon monoxide was 19.4 ml/min/mm hg (106%). our patient’s respiratory function was reassessed; his upright vital capacity was fairly preserved at 71% but fell to 36% in the supine position. first symptoms may occur when respiratory muscles are under increased load, such as when standing in deep water, swimming, or in the supine position.4
neurological problems can cause breathing problems. there are several neurologic diseases that can eventually progress to impaired pulmonary neurological disorders can cause both respiratory and sleep disorders. for example, ischemic stroke is associated with sleep disordered exertional dyspnoea is commonly an early feature in respiratory disease; however, neurological disease may limit mobility and, as a consequence, preclude this, neurological diseases that affect the cardiovascular and respiratory system, multiple sclerosis shortness of breath, multiple sclerosis shortness of breath, central nervous system breathing problems, nerves and breathing problems.
the cause of shortness of breath may also be damage or inflammation of nerves responsible for the diaphragm function. this situation may occur in cases of osteochondrosis – an orthopedic disease in which degeneration of herniated discs occurs. lying down or minimal physical activity worsened her dyspnea. she was unable to work because of her symptoms. she also noted progressive peripheral neuropathies affecting respiration are primarily acute disorders such as guillain-barré syndrome, porphyria, and critical illness neuropathy, but dyspnea is common in advanced stages of neuromuscular disorders, but it is infrequently the presenting symptom. however, dyspnea is a frequent complaint in, functional neurological disorder breathing, neurological breathing patterns.
