Hyperventilation vs. Tachypnea: What's the Difference?

Edited by Aimie Carlson || By Janet White || Published on March 6, 2024
Hyperventilation is abnormally fast or deep breathing usually caused by anxiety or panic, while tachypnea is rapid breathing due to medical conditions like fever.

Key Differences

Hyperventilation involves an increase in breathing rate or depth, leading to excessive expulsion of carbon dioxide, often triggered by stress, anxiety, or panic. This process can result in a variety of symptoms, including dizziness, palpitations, and a sense of breathlessness. Tachypnea, on the other hand, is characterized by a rapid breathing rate that exceeds the normal range for the individual's age, often in response to a physiological need to increase oxygen uptake or carbon dioxide expulsion.
In hyperventilation, the body loses carbon dioxide too quickly, leading to a shift in blood pH and causing symptoms like tingling in the hands or around the mouth, muscle spasms, and even fainting. The treatment often involves techniques to increase carbon dioxide levels in the body, such as breathing into a paper bag or practicing controlled breathing exercises. Tachypnea often signals the body's attempt to compensate for a reduced ability to exchange gases, like in cases of pneumonia or chronic obstructive pulmonary disease (COPD). The treatment for tachypnea focuses on addressing its underlying cause, such as administering antibiotics for an infection or providing supplemental oxygen for conditions that impair oxygenation.
Hyperventilation is often self-limiting and can be managed through relaxation techniques and reassurance, tachypnea requires medical intervention to treat its root cause. In both conditions, monitoring and, if necessary, medical evaluation are crucial to prevent complications and ensure proper management.

Hyperventilation and Tachypnea Definitions


Rapid and deep breathing lowering CO2.
The scare caused him to hyperventilate.


Breathing faster than normal.
After climbing the stairs, his tachypnea was noticeable.


Overbreathing leading to dizziness.
He hyperventilated after running, feeling dizzy.


Rapid breathing rate.
The high fever caused the child to experience tachypnea.


Breathing faster than necessary.
During the panic attack, she started hyperventilating.


Accelerated breaths per minute.
Tachypnea was observed in the patient with heart failure.


Abnormally increased breathing rate.
Fearing the worst, she hyperventilated in the waiting room.


Fast breathing signaling distress.
The emergency team noted her tachypnea immediately.


Excessive breathing due to anxiety.
Nervous about her speech, she began to hyperventilate.


Increased respiratory rate due to illness.
Tachypnea in patients with pneumonia is common.


Abnormally fast or deep respiration, which results in the loss of carbon dioxide from the blood, thereby causing a fall in blood pressure, tingling of the extremities, and sometimes fainting.


Rapid breathing.


(medicine) the state of breathing faster or deeper than necessary


Alternative spelling of tachypnoea


The act or process of hyperventilating; breathing rapidly and deeply.


A condition in which alveolar carbon dioxide concentration is markedly lower than normal, usually due to breathing rapidly and deeply.


An increased depth and rate of breathing greater than demanded by the body needs; can cause dizziness and tingling of the fingers and toes and chest pain if continued


What triggers hyperventilation?

Anxiety, panic attacks, and stress are common triggers.

Is hyperventilation harmful?

It can be uncomfortable but is generally not harmful if managed.

Can physical activity cause tachypnea?

Yes, along with medical conditions like fever or lung disease.

Can tachypnea be a symptom of COPD?

Yes, it's often observed in chronic obstructive pulmonary disease.

Can anxiety cause tachypnea?

While anxiety primarily causes hyperventilation, it can indirectly lead to tachypnea.

What is the main difference between hyperventilation and tachypnea?

Hyperventilation is mainly psychological, while tachypnea is due to physical health issues.

Is hyperventilation always caused by panic attacks?

No, other factors like pain or injury can also cause it.

How do you calm someone hyperventilating?

Encourage slow, controlled breathing or breathing into a paper bag.

How is tachypnea treated?

Treatment focuses on the underlying cause, such as medication for infection.

Can stress management help with hyperventilation?

Yes, stress reduction techniques can significantly help.

Are there long-term effects of hyperventilation?

Rarely, if it's recurrent, it might indicate an anxiety disorder.

Is hyperventilation a sign of a heart attack?

It can be a symptom, but not specifically indicative of a heart attack.

Can children experience hyperventilation or tachypnea?

Yes, both conditions can occur in children due to various causes.

What tests diagnose hyperventilation?

Diagnosis is often based on symptoms and ruling out other conditions.

Is there a genetic predisposition to hyperventilation?

Not specifically, though anxiety disorders may have a genetic component.

How quickly does tachypnea develop?

It can develop rapidly in response to an underlying condition.

What are the risks of untreated tachypnea?

It can lead to hypoxia, affecting organ function if not treated.

Is tachypnea common in fever?

Yes, as the body attempts to compensate for increased metabolism.

Can both hyperventilation and tachypnea occur at the same time?

Yes, particularly if stress induces rapid breathing in someone with a lung condition.

Does tachypnea affect oxygen levels?

It can, especially if due to lung or heart conditions.
