Tachypnea is defined as increased breathing speed, above thestandard respiratory rate of 14 to 20 inhales per minute. Tachypnea increases the so-called minute ventilation and also, if the inhale volume is smaller, tachypneaonly compensates for decreased air volume, which is used in each respirationcycle. Patients that already have some lung condition (lung fibrosis, elevated diaphragm,pleural pain etc.) sometimes breathe superficially and fast (tachypnea). Some patientscompensate by increasing the minute ventilation to adjust to bigger airexchange, which is needed in physical activity, when the body temperature ishigh, in hyper metabolic conditions, during excitement, etc.
Conditions that have tachypnea as the symptom
There are several conditions that have tachypnea as asymptom. Bronchial asthma happens because of obstruction in breathing pathways, which is fortunately, reversible. This obstruction happens because of the allergens and some other substances, which means that the causing factors arepollen, mites, animal hair, medications, food, industry chemicals, and others. Infectionsof breathing passages are one of the main causes of asthma. Patient cannot speakwithout losing breath, tachypnea emerges with more than 28 inhales in aminute. Cianosis is also present, dyspnea too, whizzing, coughing, tachycardia, and systolic paradox, which is decreased blood pressure in the inhale stage of breathing.Depending on the asthma intensity, different medication therapies are used.
Pneumonia also includes tachypnea as a symptom and it is an inflammation of the lung tissue. Different causes can lead to tachypnea inpneumonia, which can be caused by a virus or bacteria, but high temperatureis always present, and there are also exhaustion, heavy breathing, and dyspnea.
Tachypnea is also present in pleuritis, inflammation ofpleura, inflammation of diaphragm, several types of intoxication etc. Actually,in almost each condition that includes damaging respiratory system in any possibleway (physical trauma, infection, both viral and bacterial, inflammation, psychologicalconditions such as panic attack, intensive physical activity etc.) tachypneaoccurs. The only situation when tachypnea is normal and does not needtherapy is while exercising, because when exercise is finished, breathing will slowlyreturn to a normal state. Trained, professional sportsmen need a lot morephysical exertion in order for tachypnea to start.
Treatment depends of the cause of tachypnea, meaning that the underlying condition has to be treated first, in order to subdue tachypnea andreturn the breathing process into a normal state. With this said, there are numeroustreatments and therapies, each one being different and specialized in dealing with thementioned underlying cause. Of course, if the underlying condition is seriousand dangerous, tachypnea has to be subdued quickly and effectively.
