Manifestations: Breathing patterns are often irregular and shallow. The infants respiration rate should be between 30 and 60 breaths per minute with preference for nasal breathing. Ribs expands horizontally. Breath sounds should be clear and equal in both lungs. Abdominal breathing is normal. Acrocyanosis is a normal finding. [1]
For example, high blood glucose levels, called hyperglycemia, can boost the number of breathing movements. Conversely, hypoglycemia can reduce the number of fetal breathing movements. Tobacco use is also known to lower fetal breathing rates. Fetal breathing may help tone the muscles in preparation for breathing movements once the fetus is born.
Tidal breathing is normal, resting breathing; the tidal volume is the volume of air that is inhaled or exhaled in only a single such breath. The average human respiratory rate is 30–60 breaths per minute at birth, [ 2 ] decreasing to 12–20 breaths per minute in adults.
Respiration rates may increase with fever, illness, or other medical conditions. [2] Inaccuracies in respiratory measurement have been reported in the literature. [3] One study compared respiratory rate counted using a 90-second count period, to a full minute, and found significant differences in the rates. [citation needed].
Cheyne–Stokes respiration is a breathing pattern consisting of alternating periods of rapid and slow breathing, which may result from a brain stem injury. [12] Cheyne-Stokes respiration may be observed in newborn babies, but this is occasionally physiological (normal). Chest retractions may be observed in patients with asthma.
Periodic breathing is clusters of breaths separated by intervals of apnea or near-apnea. As opposed to normal breathing which is usually regular, periodic breathing is defined as three or more episodes of central apnea lasting at least 4 seconds, separated by no more than 30 seconds of normal breathing.

Persistent fetal circulation is a condition caused by a failure in the systemic circulation and pulmonary circulation to convert from the antenatal circulation pattern to the "normal" pattern. Infants experience a high mean arterial pulmonary artery pressure and a high afterload at the right ventricle.
