Labored breathing

Labored respiration or labored breathing is an abnormal

Labored breathing is distinguished from shortness of breath or dyspnea, which is the sensation of respiratory distress rather than a physical presentation.

Still, many^[2] simply define dyspnea as difficulty in breathing without further specification, which may confuse it with e.g. labored breathing or tachypnea (rapid breathing).^[3] Labored breathing has occasionally been included in the definition of dyspnea as well.^[4] However, in the standard definition, these related signs may be present at the same time, but do not necessarily have to be. For instance, in respiratory arrest by a primary failure in respiratory muscles the patient, if conscious, may experience dyspnea, yet without having any labored breathing or tachypnea. The other way around, labored breathing or tachypnea can voluntarily be performed even when there is no dyspnea.

Presentations

Presentations of labored respiration include:

• Hyperpnea - faster and/or deeper breathing
• Tachypnea - increased breathing rate
• Retractions or recessions – sucking in of the skin, around the ribs^[5] and the top of the sternum^[6]
• Use of
  accessory muscles of respiration rather than only the diaphragm

• Severe metabolic acidosis, particularly diabetic ketoacidosis (DKA) but also kidney failure. The specific associated breathing pattern is called Kussmaul breathing.
• Cardiac disease^[7]
• Respiratory failure^[7]
