What is the term for slow breathing?

Breathing that stops from any cause is called apnea. Slowed breathing is called bradypnea. Labored or difficult breathing is known as dyspnea.

Considerations

 

Apnea can come and go and be temporary. This can occur with obstructive sleep apnea, for example.

Prolonged apnea means a person has stopped breathing. If the heart is still active, the condition is known as respiratory arrest. This is a life-threatening event that requires immediate medical attention and first aid.

Prolonged apnea with no heart activity in a person who is not responsive is called cardiac (or cardiopulmonary) arrest. In infants and children, the most common cause of cardiac arrest is respiratory arrest. In adults, the opposite usually occurs, cardiac arrest leads to respiratory arrest.

 

Causes

 

Breathing difficulty can occur for many different reasons. The most common causes of apnea in infants and small children are usually different from the most common causes in adults.

Common causes of breathing difficulties in infants and young children include:

  • Asthma

When to Contact a Medical Professional

 

Seek immediate medical attention or call your local emergency number (such as 911) if a person with any type of breathing problem:

  • Becomes limp
  • Has a seizure
  • Is not alert (loses consciousness)
  • Remains drowsy
  • Turns blue

If a person has stopped breathing, call for emergency help and perform CPR (if you know how). When in a public place, look for an Automated External Defibrillator (AED) and follow the directions.

What to Expect at Your Office Visit

 

CPR or other emergency measures will be done in an emergency room or by an ambulance emergency medical technician (EMT) or paramedic.

Once the person is stable, the health care provider will do a physical exam, which includes listening to heart sounds and breath sounds.

Heart sounds

A heart murmur is a blowing, whooshing, or rasping sound heard during a heartbeat. The sound is caused by turbulent (rough) blood flow through the h...

Questions will be asked about the person's medical history and symptoms, including:

Time pattern

  • Has this ever happened before?
  • How long did the event last?
  • Has the person had repeated, brief episodes of apnea?
  • Did the episode end with a sudden deep, snorting breath?
  • Did the episode occur while awake or asleep?

Recent health history

  • Has the person had a recent accident or injury?
  • Has the person been ill recently?
  • Was there any breathing difficulty before breathing stopped?
  • What other symptoms have you noticed?
  • What medicines does the person take?
  • Does the person use street or recreational drugs?

Diagnostic tests that may be done include:

  • Airway support, including oxygen, breathing tube through the mouth (intubation), and breathing machine (ventilator)
  • Blood and urine tests
  • Chest x-ray

    Chest x-ray

What does slow breathing indicate?

Bradypnea is when a person's breathing is slower than usual for their age and activity levels. For an adult, this will be under 12 breaths per minute. Slow breathing can have many causes, including heart problems, brain stem problems, and drug overdose.

What is Tachypnea and bradypnea?

Bradypnea is a respiratory rate that is lower than normal for age. Tachypnea is a respiratory rate that is greater than the normal for age. Hyperpnea in increased volume with or without an increased rate of breathing.

What is slow and shallow breathing called?

Respiratory depression, or hypoventilation, refers to a slow, shallow breathing rate. There are many causes, some of which are more serious than others.

What happens if you breathe slower?

Slow breathing (or: belly breathing, diaphragmatic breathing) helps expand your lungs and increases efficiency in oxygen absorption and supply. It massages all your organs, strengthens the muscles of your chest, improves your digestion and the quality of your sleep.
