  1. Initiation of exercise

    1. The increase in respiration rate due to exercise is because our bodies, especially our muscles, are spending more energy and producing more carbon dioxide. With this, our body has to respire more to expel waste gas, carbon dioxide.

  2. Moderate exercise

    1. With the increase in work for our muscles (i.e. working harder than usual), there will also be an increase in the usage of oxygen for energy production. As a result, our muscles will produce, at a greater rate, carbon dioxide. With this, there will be an increase in respiration rate to expel carbon dioxide.

  3. Asthma attack

    1. Asthma attack causes the airways to become swollen and inflamed. Moreover, there may be an excess secretion of mucus in the membranes of the patient’s airway linings. Consequently, with the swelling of the airway and excess production of mucus, it would be harder for them to breathe.

  4. Abrupt ascent into high altitudes

    1. As the altitude increases, air pressure drops and gas molecules (e.g. oxygen) lessen. With this, there will be less oxygen to breathe in, hence increase in the respiratory rate.

  5. Pneumonia

    1. Pneumonia causes your air sacs and alveoli in your lungs to be inflamed/filled with mucus. With this, it would be harder for the lungs to perform gas exchange due to the decrease in efficiency of the lungs. Therefore, there would be an increase in respiratory rate.

  6. Paralysis of phrenic nerve

    1. The paralysis of the phrenic nerve would lead to weakened or paralysis of the diaphragm that is essential for breathing. Consequently, the patient would experience shortness of breath and sleeping problems.. 

  7. Severe tuberculosis with resulting lung scar tissue

    1. Tuberculosis destroys/scars lung tissues. Consequently, the lung gets stiffer and is less efficient at delivering oxygen. With this, it makes the lungs more difficult to expand, making breathing harder.

  8. Severe anemia

    1. Anemia, or iron deficiency, is when the body does not have enough or could not produce healthy red blood cells or hemoglobin that are both important for carrying oxygen to the different parts of the body. As a result, an anemic person would experience being tired and shortness of breath.

  9. Advanced COPD (chronic obstructive pulmonary disease)

    1. COPD inflames the airways, causing an inability to stretch and the destruction of the walls of the air sacs. This would mean that there will be less gas exchange in the lungs. Consequently, it would make breathing difficult.

  10. Advanced pregnancy

    1. With the baby occupying more space in the uterus, it would eventually come to a point where it will press to the mother’s diaphragm. As such, this would make it harder for the lungs to fully expand, which would cause shortness of breath.
