Just Breathe Deeply
A feeling of panic is a very common phenomenon. We all panic when we lose our keys or we’re late for an appointment, for example. However, these are not panic attacks. A true panic attack involves an intense feeling of fear that may last for hours.

- The dissolved CO2 in blood is in equilibrium with protons and bicarbonate anion. The amounts of each constituent at any given moment is influenced by Le Châtelier’s principle and governed mainly by the inhaling and exhaling of carbon dioxide. If CO2 levels are high, the equilibrium shifts toward the formation of more hydrogen and bicarbonate ions, producing a lower blood pH. If CO2 levels are low, the shift is in the opposite direction, hydrogen ion concentration decreases and the pH goes up.
- In a panic attack, the individual hyperventilates, exhaling more CO2 than normal. This causes the blood pH to increase as more hydrogen ions are consumed to restore the equilibrium, producing a situation known as respiratory alkalosis. This is not usually life-threatening and can be dealt by slow breathing. Some physicians recommend breathing into a paper bag since that will lead to more CO2 being re-inhaled, but this is not always effective.
