Hyperventilation is irregular breathing that occurs when the rate or tidal volume of breathing eliminates more carbon dioxide than the body can produce. [ 1 ] [ 2 ] [ 3 ] This leads to hypocapnia , a reduced concentration of carbon dioxide dissolved in the blood.
Hypocapnia (from the Greek words ὑπό meaning below normal and καπνός kapnós meaning smoke), also known as hypocarbia, sometimes incorrectly called acapnia, is a state of reduced carbon dioxide in the blood. [1] Hypocapnia usually results from deep or rapid breathing, known as hyperventilation. Hypocapnia is the opposite of hypercapnia.
Hyperventilation syndrome (HVS), also known as chronic hyperventilation syndrome (CHVS), dysfunctional breathing hyperventilation syndrome, cryptotetany, [1] [2] spasmophilia, [3] [4] [5] latent tetany, [4] [5] and central neuronal hyper excitability syndrome (NHS), [3] is a respiratory disorder, psychologically or physiologically based, involving breathing too deeply or too rapidly ...
Obstructive shock is a form of shock associated with physical obstruction of the great vessels of the systemic or pulmonary circulation. [13] Several conditions can result in this form of shock. Cardiac tamponade, in which fluid in the pericardium prevents inflow of blood into the heart (venous return). [9]
Take a deep breath and discover how to help them out. What They Do YOU KNOW FROM high school that your lungs bring in oxygen and move it to the blood (inhale) while taking carbon dioxide out of ...
Atherosclerosis is characterized by the build-up of plaque inside your blood vessels. It can lead to stenosis, which is a narrowing of your artery walls. Plaque is a fatty substance made up of:
The pulmonary circulation is a division of the circulatory system in all vertebrates. The circuit begins with deoxygenated blood returned from the body to the right atrium of the heart where it is pumped out from the right ventricle to the lungs.
Clinically, it manifests as fever, persistent cough, difficulty breathing, and pleuritic chest pain that worsens with deep breaths. [19] Hemothorax: A hemothorax occurs from accumulation of blood in the pleural cavity, commonly due to trauma, vascular injury, or coagulopathies, which can disrupt lung expansion and oxygenation.
