Factors that may induce or sustain [2] hyperventilation include: physiological stress, anxiety or panic disorder, high altitude, head injury, stroke, respiratory disorders such as asthma, pneumonia, or hyperventilation syndrome, [5] cardiovascular problems such as pulmonary embolisms, anemia, an incorrectly calibrated medical respirator, [1] [3 ...
In medicine, the Faget sign—sometimes called sphygmothermic dissociation—is the unusual pairing of fever with bradycardia (slow pulse). (Fever is usually accompanied by tachycardia (rapid pulse), an association known by the eponym "Liebermeister's rule".)
Alveolar hypoventilation (decreased minute volume due to reduced respiratory muscle activity, e.g. in acute neuromuscular disease); this form can also cause type 2 respiratory failure if severe. Diffusion problem (oxygen cannot enter the capillaries due to parenchymal disease, e.g. in pneumonia or ARDS ).
Fever, hyperventilation, diarrhea and severe infections can also cause tachycardia, primarily due to increase in metabolic demands. [citation needed] Upon exertion, sinus tachycardia can also be seen in some inborn errors of metabolism that result in metabolic myopathies, such as McArdle's disease (GSD-V).
The most common causes of pneumonia are bacteria and viruses, Dr. Carrie Horn, chief medical officer at leading U.S. respiratory hospital National Jewish Health in Denver and a hospitalist ...
Tachycardia is often present, but other specific findings may be present based on the underlying cause. [10] [23] At the bedside, point-of-care echocardiography should be used. [22] This is non-invasive and can help diagnose the four types of shock. [24] Echocardiography can look for ventricular dysfunction, effusions, or valve dysfunction.
A bacterium called Mycoplasma pneumoniae causes two types of respiratory tract infections: the more common chest cold, tracheobronchitis, and the less common lung infection, walking pneumonia.
Hypercapnia (from the Greek hyper, "above" or "too much" and kapnos, "smoke"), also known as hypercarbia and CO 2 retention, is a condition of abnormally elevated carbon dioxide (CO 2) levels in the blood.
