Abnormal breathing from a mechanical standpoint can occur when the breathing has become inefficient or is imbalanced. For example a person uses the diaphragm only, or only their external intercostals or when the accessory muscles or helper muscles have shifted into primary roles. Or if the mobility of the rib cage, overlying tissues or vertebrae do not move well enough to allow the mechanics of breathing to work at their top ability.
Other abnormal patterns of breathing include:. Our physical therapist has a specialized understanding of breathing mechanics both good and bad and the effects on overall health and function. At Graham Therapy and Fitness, P. These techniques work to strengthen or restore the natural breathing mechanisms in our body to create strength and promote optimal breathing motions.
Consider a visit to your physical therapist for a breathing mechanics evaluation. Physical therapists have the ability to devise a plan to help strengthen and mobilize our bodies to breathe and cough more efficiently. It can be empowering to learn what each of us already has within us, a functioning respiratory system. Optimize your breathing mechanics Contact Us today! The Forgotten Biomechanics of Breathing April 22nd, Breathing Mechanics On a day to day basis, an adult takes breaths per minute.
Normal Breathing Mechanics Why understand normal breathing? Our diaphragm is a large domed shaped muscle. The diaphragm travels down into the abdomen as we take a breath in or inhale, allowing air to travel inward into the lungs. Simultaneously, the external intercostal muscles muscles between the ribs contribute to inhalation breath in by lifting the ribs up and out, also allowing air to travel into the lungs. The external intercostal muscles and diaphragm contribute to an increase in the volume opening of the thoracic cavity which allows the lungs to bring air and oxygen inward.
As we exhale, air leaves the lungs and carries carbon dioxide out of the lungs. The rib cage provides the site for the muscles to attach which allows the thoracic cage to expand larger during the inhale, or compress the thorax during exhale.
The rib cage also helps to protect our internal organs. At the back of the body, the rib cage articulates with the 12 thoracic vertebrae back bones. The intercostal muscles are the muscles between the ribs. During breathing, these muscles normally tighten and pull the rib cage up. Your chest expands and the lungs fill with air. Intercostal retractions are due to reduced air pressure inside your chest.
This can happen if the upper airway trachea or small airways of the lungs bronchioles become partially blocked. As a result, the intercostal muscles are sucked inward, between the ribs, when you breathe. This is a sign of a blocked airway. Any health problem that causes a blockage in the airway will cause intercostal retractions. Seek medical help right away if intercostal retractions occur.
This can be a sign of a blocked airway, which can quickly become life threatening. Also seek medical care if the skin, lips, or nailbeds turn blue, or if the person becomes confused, drowsy, or is hard to wake up. In an emergency, the health care team will first take steps to help you breathe. You may receive oxygen, medicines to reduce swelling, and other treatments.
When you can breathe better, the health care provider will examine you and ask about your medical history and symptoms, such as:. Philadelphia, PA: Elsevier; chap 1. This forces the abdominal organs downwards, allowing for a decrease in pressure and an increase in volume to occur in the thoracic cavity, thus permitting air to rush into the lungs.
After taking a breath in, air is passively let back out of the lungs due to the diaphragm relaxing and returning back to its starting dome position. Attaching diagonally between each rib are the small intercoastal muscles. When breathing in, these muscles contract to lift and expand the ribcage. Just like when the diaphragm contracts, this allows for a decrease in pressure and increase in volume to occur in the thoracic cavity.
The more air in the lungs, the more oxygen. The more oxygen, the better the blood is oxygenated for the entire body to function at a higher level. This can cause a decrease in oxygen supply to the body, thus causing a decrease in daily, recreational, or athletic capabilities.
