external/ internal intercostals
Aid in respiration - usually deeper breathing
A Internal Positive Pressure aid is an artificial aid for breathing used if you have problems with your muscles or lungs.
Both aid in the expansion and relaxation of lungs.
The diaphragm is the main muscle of respiration. Other muscles, such as the intercostals, also aid breathing.
These are diaphragm and externa intercostal muscles in quiet breathing and sternocliedomastoid ,sclene muscles,anterior serrati in heavy breathing
To improve your breathing by engaging your abdominal muscles, focus on breathing deeply and slowly while consciously contracting your abdominal muscles. This can help strengthen your diaphragm and improve the efficiency of your breathing. Practice diaphragmatic breathing exercises regularly to enhance your breathing technique.
it stands for "is the patient breathing?"
Pleural muscles do not aid in ventilation. The pleural space acts as a lubricated surface that allows the lungs to expand and contract during breathing, but it is not a muscle that directly influences the movement of air in and out of the lungs.
During forced breathing, the accessory muscles of respiration become active to assist the primary muscles. These include the sternocleidomastoid and scalene muscles in the neck, which help elevate the rib cage, as well as the pectoralis major and minor muscles in the chest. The abdominal muscles also engage during forced exhalation to help push air out of the lungs more effectively. This coordinated effort increases the volume of air exchanged during vigorous activities or respiratory distress.
diaphragm
Myopathy of the breathing muscles is serious as there may be serious breathing difficulties and increased risk for pneumonia, flu, and other respiratory infections.
Forced breathing, or active breathing, involves the use of additional muscles to increase the volume of air inhaled or exhaled, typically during vigorous activities or exercises. In contrast, quiet breathing, or passive breathing, relies primarily on the diaphragm and intercostal muscles, functioning without conscious effort. During forced inhalation, accessory muscles such as the sternocleidomastoid and scalene muscles are engaged, while forced exhalation may involve the abdominal muscles and internal intercostals to expel air more forcefully.
