Insights
Persistent periodic breathing (PB) in term infants after one month is often linked to obstructive and central sleep apnea syndromes, and gastroesophageal reflux (GER). Most infants improve within their first year.
Area of Science:
- Pediatrics
- Sleep Medicine
- Neonatology
Background:
- Periodic breathing (PB) is common in newborns but typically resolves within months.
- Persistent PB beyond the neonatal period is less understood.
- This study investigates term infants with persistent PB after one month of age.
Purpose of the Study:
- To characterize term infants experiencing persistent periodic breathing (PB) beyond one month of life.
- To analyze polysomnography (PSG) findings in these infants.
- To identify associated conditions and outcomes.
Main Methods:
- Retrospective case series of 10 term infants with persistent PB symptoms.
- Polysomnography (PSG) was used to define and quantify PB.
- Infants were assessed for obstructive and central apnea indices, and gastroesophageal reflux (GER).
Main Results:
- Persistent PB was observed in 18.1% of total sleep time (TST) before 3 months and 4.7% between 3-6 months.
- Most infants (9/10) had an obstructive apnea-hypopnea index >10/h; 5/10 had a central apnea index >5/h.
- Gastroesophageal reflux (GER) was suspected in 80% of cases; all infants improved symptomatically within a year.
Conclusions:
- Persistent, symptomatic PB after one month in term infants is associated with obstructive and/or central sleep apnea syndromes.
- Gastroesophageal reflux (GER) is a common comorbidity.
- These infants generally show symptom improvement within the first year of life.
Introduction:
Periodic breathing (PB) is considered physiological in the neonatal period and usually disappears in the first months of life. There are few data available on persistent PB after the neonatal period. The objective of this study was to characterize infants born at term with persistent PB after the age of 1 month through polysomnography (PSG) performed during symptoms.
Methods:
This retrospective case series included infants born at term between 2012 and 2021, without an underlying disease, who presented with symptoms of persistent PB during a PSG. Persistent PB was defined as more than 1 % of total sleep time (TST) of PB after 1 month of life, and PB was defined as a succession of at least three episodes of central apnea lasting more than 3 s and separated by less than 20 s of normal breathing.
Results:
A total of 10 infants born at term were included. They underwent PSG for brief resolved unexplained events, desaturation, pauses in breathing, cyanosis, and/or signs of respiratory distress. The percentage of TST spent with PB was 18.1 % before 3 months of age (n = 7), and 4.7 % between 3 and 6 months of age (n = 10). During the first PSG, ≥3 % of desaturation events were observed in 77-100 % of the PB episodes. At the first PSG, nine of the 10 infants had an obstructive apnea-hypopnea index of >10/h and five of 10 infants had a central apnea index of >5/h. Gastroesophageal reflux (GER) was suspected in eight infants. All infants showed improvement in the initial symptoms during the first year of life.
Conclusion:
This study presents cases of persistent and symptomatic PB after 1 month of life in infants born at term. The interesting finding was the presence of obstructive sleep apnea syndrome and/or central apnea syndrome in the majority of children, along with GER.

Assessment of Ventilation II: Respiratory Depth and Rhythm
Respiratory depth measures the volume of air inhaled or exhaled during a breath. It can vary from shallow to deep and typically remains consistent when a person is at rest or asleep. Occasionally, individuals will automatically inhale deeply, known as sighing, which inflates the lungs with more air than normal breathing.
To assess respiratory depth, observe the degree of chest excursion or movement:
