The most common findings in people with tension pneumothorax are chest pain and respiratory distress, often with an increased heart rate (tachycardia) and rapid breathing in the initial stages. Other findings may include quieter breath sounds on one side of the chest, low oxygen levels and blood pressure , and displacement of the trachea away ...
Accessory muscle use, including the scalene and intercostal muscles [5] Diaphragmatic breathing, paradoxical movement of the diaphragm outwards during inspiration; Intercostal indrawing; Decreased chest–chest movement on the affected side; An increased jugular venous pressure, indicating possible right heart failure [5]
The heart is a muscular organ situated in the mediastinum.It consists of four chambers, four valves, two main arteries (the coronary arteries), and the conduction system. The left and right sides of the heart have different functions: the right side receives de-oxygenated blood through the superior and inferior venae cavae and pumps blood to the lungs through the pulmonary artery, and the left ...
Cardiac muscle (also called heart muscle or myocardium) is one of three types of vertebrate muscle tissues, the others being skeletal muscle and smooth muscle. It is an involuntary, striated muscle that constitutes the main tissue of the wall of the heart .
The strength of heart muscle contractions controls the stroke volume. This can be influenced positively or negatively by agents termed inotropes. [41] These agents can be a result of changes within the body, or be given as drugs as part of treatment for a medical disorder, or as a form of life support, particularly in intensive care units.
In obstructive shock, the underlying problem is not the pump. Rather, the input into the heart (venous return) is decreased or the pressure against which the heart is pumping is higher than normal. [7] Treating the underlying cause can reverse the shock. [1] For example, tension pneumothorax needs rapid needle decompression.
Key symptoms include sharp chest pain, difficulty breathing, low blood pressure in severe cases, and diminished breath sounds accompanied by dullness to percussion over the affected area. [20] Pneumothorax: Those who are at a higher risk of developing pneumothorax are tall, slim male smokers who have had underlying lung diseases such as ...
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
