Causes. Tachypnea can be caused by a number of conditions. Chronic conditions like asthma, lung disease, anxiety, or obesity can lead to tachypnea. It may also be caused by acute conditions like pulmonary embolism (blood clots in lungs), choking, heart failure, shock, or heatstroke.

Secondly, what is a dangerous respiratory rate? A respiration rate under 12 or over 25 breaths per minute while resting is considered abnormal. Among the conditions that can change a normal respiratory rate are asthma, anxiety, pneumonia, congestive heart failure, lung disease, use of narcotics or drug overdose.

Accordingly, what happens during tachypnea?

Rapid, shallow breathing, also called tachypnea, occurs when you take more breaths than normal in a given minute. When a person breathes rapidly, its sometimes known as hyperventilation, but hyperventilation usually refers to rapid, deep breaths. The average adult normally takes between 12 to 20 breaths per minute.

What is the difference between tachypnea and Hyperpnea?

Tachypnea refers to rapid breathing, especially rapid and shallow breathing. Hyperpnea is abnormally deep breathing, with or without an increase in respiratory rate. Hyperventilation implies a frequency and/or depth to the ventilation such that the levels of CO2 in the body drop to abnormally low levels.
