Hyperventilation is rapid or deep breathing that can occur with anxiety or panic. It is also called overbreathing, and may leave you feeling breathless.

Alternative NamesRapid deep breathing; Breathing - rapid and deep; Overbreathing; Fast deep breathing; Respiratory rate - rapid and deep
ConsiderationsWhen you breathe, you inhale oxygen and exhale carbon dioxide. Excessive breathing leads to low levels of carbon dioxide in your blood. This causes many of the symptoms you may feel if you hyperventilate.
Feeling very anxious or having a panic attack are the usual reasons that you may hyperventilate. However, rapid breathing may be a symptom of a disease, such as:
Your doctor will determine the cause of your hyperventilation. Rapid breathing may be a medical emergency -- unless you have experienced this before and have been reassured by your doctor that your hyperventilation can be self treated.
Often, panic and hyperventilation become a vicious cycle. Panic leads to rapid breathing, and breathing rapidly can make you feel panicked.
If you frequently overbreathe, you may have hyperventilation syndrome that is triggered by emotions of stress, anxiety, depression, or anger. Occasional hyperventilation from panic is generally related to a specific fear or phobia, such as a fear of heights, dying, or closed-in spaces (claustrophobia).
If you have hyperventilation syndrome, you might not be aware you are breathing fast. However, you will be aware of having many of the other symptoms, including:
Your doctor will look for other medical illnesses before diagnosing hyperventilation syndrome.
If your doctor has explained that you hyperventilate from anxiety, stress, or panic, there are steps you can take at home. You, your friends, and family can learn techniques to stop you from hyperventilating when it happens and to prevent future attacks.
If you start hyperventilating, the goal is to raise the carbon dioxide level in your blood, which will put an end to most of your symptoms. There are several ways to do this:
Over the long term, there are several important steps to help you stop overbreathing:
If these methods alone are not preventing your overbreathing, your doctor may recommend a beta blocker medication.

Your doctor will perform a careful physical examination.
To get your medical history, your doctor will ask questions about your symptoms, such as:
The doctor will assess how rapidly you are breathing at the time of the visit. If you are not breathing quickly, the physician may try to induce hyperventilation by instructing you to breathe a certain way.
While you hyperventilate, the doctor will ask how you feel and watch how you breathe -- including what muscles you are using in your chest wall and surrounding areas.

During hyperventilation, blood pCO2 levels decrease. This causes a shift in the equilibrium of p-cresol sulfate (P-CRES) metabolism towards the production of P-CRES. This leads to higher blood P-CRES levels during hyperventilation.
decrease in blood CO2 concentration and a rise in pH
Hyperventilation can lead to a decrease in carbon dioxide levels in the blood, which can cause symptoms such as dizziness, tingling in the extremities, and feelings of confusion or lightheadedness. This can also lead to respiratory alkalosis, a condition characterized by a higher pH level in the blood.
During hyperventilation, tidal volume typically increases. This is because the individual is breathing at a faster rate and often more deeply than usual, which results in a larger volume of air being exchanged with each breath.
Hyperventilation causes 'Decrease' in carbon bi oxide level in blood. It causes, what is called as 'Respiratory alkalosis'. Symptoms are dizziness, light headedness and numbness of the hands and feet. If patient continue to hyperventilate, she lands up in a condition called 'Tetany' witch is common in females, as they are socially discriminated. In Tetany, patient's thumb get typically 'Inward' and she may land up in fits. If you willfully do hyperventilation, you will fall down, without your knowledge and may get head injury and die.
You have correctly spelled hyperventilation.
Tachypnea
Yes, hyperventilation is can cause dead things.
They are not the same. Hyperventilation can be a symptom of anxiety.
Yes, chest tightness can be due to hyperventilation. More specifically is it due to Hyperventilation Syndrome which is a respiratory disorder caused by the psyche.
Some sort of psychological stress can trigger hyperventilation syndrome.
As a sufferer of hyperventilation I would say it does. Not massively though but you can feel the difference.
Hyperventilation raises body pH. Hypoventilation lowers body pH.
No, hyperventilation means increased rate and depth of breathing.
hyperventilation
Hyperventilation Syndrome is almost always a disease of young adults. Hyperventilation syndrome (HVS) is an episodic disorder that often presents with chest pain and a tingling sensation of the fingertips (paresthesia) and around the mouth, as well as deep and labored breathing (causing hyperventilation), although chronic but subtle hyperventilation can cause these symptoms too. Hyperventilation is breathing in excess of what the body needs. This is sometimes called overbreathing. Rapid or deep breathing is sometimes seen in very serious conditions such as infection, bleeding, or heart attack.
Hyperventilation (hyper = a lot + ventilation = breathing) is a medical term. It is also known as "Rapid Breathing", "Deep Breathing" or "Overbreathing". The most common cause of spontaneous hyperventilation is anxiety or panic.
