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 most often leads to respiratory arrest. Causes Breathing difficulty can occur for many reasons. The most common causes of apnea in infants and small children are different from the most common causes in adults.Common causes of breathing difficulties in infants and young children include:Asthma AsthmaAsthma is a chronic disease that causes the airways of the lungs to swell and narrow.
