Diaphragmatic rupture (also called diaphragmatic injury or tear) is a tear of the diaphragm, the muscle across the bottom of the ribcage that plays a crucial role in breathing. Most commonly, acquired diaphragmatic tears result from physical trauma. Diaphragmatic rupture can result from blunt or penetrating trauma and occurs in about 0.5% of ...
Many different conditions can lead to the feeling of dyspnea (shortness of breath). DiagnosisPro, an online medical expert system, listed 497 in October 2010. [1] The most common cardiovascular causes are acute myocardial infarction and congestive heart failure while common pulmonary causes include: chronic obstructive pulmonary disease, asthma, pneumothorax, and pneumonia.
Structure of diaphragm shown using a 3D medical animation still shot. The thoracic diaphragm, or simply the diaphragm (/ ˈ d aɪ ə f r æ m /; [1] Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle [2] in humans and other mammals that extends across the bottom of the thoracic ...
Shallow breathing, thoracic breathing, costal breathing or chest breathing [1] is the drawing of minimal breath into the lungs, usually by drawing air into the chest area using the intercostal muscles rather than throughout the lungs via the diaphragm. Shallow breathing can result in or be symptomatic of rapid breathing and hypoventilation ...
During normal inspiration, the diaphragm contracts and intercostal muscles pull the rib cage out. Pressure in the thorax decreases below atmospheric pressure, and air rushes in through the trachea. The flail segment will be pulled in with the decrease in pressure while the rest of the rib cage expands.
For example, a subphrenic abscess beneath the right diaphragm might cause a patient to feel pain in the right shoulder. Irritation of the phrenic nerve (or the tissues it supplies) leads to the hiccup reflex. A hiccup is a spasmodic contraction of the diaphragm, which pulls air against the closed folds of the larynx.
Certain medications can also cause or worsen acid reflux. These include calcium channel blockers to treat high blood pressure, nonsteroidal anti-inflammatory drugs, benzodiazepines, tricyclic ...
Metabolic disorders could also decrease respiratory effort. Hypoglycemia and hypotension depress the central nervous system and compromise the respiratory system. [11] Respiratory muscle weakness: Neuromuscular disorders may lead to respiratory muscle weakness, such as spinal cord injury, neuromuscular diseases, and neuromuscular blocking drugs ...
