Taking a deep breath and allowing the rib cage to fully expand can relieve the pain, however it will feel unpleasant initially. At the point of full expansion, it can feel like a rubber band snap in the chest, after which the initial pain subsides. There is no known cure for PCS; however, PCS is not believed to be dangerous or life-threatening.
Breathing over an extended period of time near maximum capacity can cause metabolic acidosis or hypoxemia, ultimately leading to respiratory muscle weakness. [12] Cardiac arrest (independent of the underlying reason) will lead to respiratory arrest within minutes. [13]
Shortness of breath (SOB), known as dyspnea (in AmE) or dyspnoea (in BrE), is an uncomfortable feeling of not being able to breathe well enough. The American Thoracic Society defines it as "a subjective experience of breathing discomfort that consists of qualitatively distinct sensations that vary in intensity", and recommends evaluating dyspnea by assessing the intensity of its distinct ...

A loss of strength or function is likely to be a medical emergency. A loss of feeling that lasts more than a minute or two indicates a need for immediate medical attention. It is only partial sensory changes, or paraesthesias , where this distinction between trivial and more serious injuries applies.
Central hypoventilation syndrome (CHS) is a sleep-related breathing disorder that causes ineffective breathing, apnea, or respiratory arrest during sleep (and during wakefulness in severe cases). CHS can either be congenital (CCHS) or acquired (ACHS) later in life.
Deep belly breathing utilizes the diaphragm to maximize lung expansion. The movement of the diaphragm naturally controls the airflow through your body, forcing the air to move deeply into your belly.
Freediving blackout – Loss of consciousness caused by cerebral hypoxia towards the end of a breath-hold dive, where hyperventilation and the subsequent hypocapnia is a cause; Hypercapnia – Abnormally high tissue carbon dioxide levels, increased level of carbon dioxide
