Perinatal Bronchopulmonary Dysplasia (BPD)

Perinatal bronchopulmonary dysplasia is a long-lasting lung disease that begins around birth in very small or very early babies. The air sacs and small airways in the lungs are still immature. After birth, these fragile lungs often need help from oxygen and breathing machines. That help can save life, but it can also stress the lungs. Infection, swelling (inflammation), and pressure or volume from the ventilator can injure the tiny airways. Over time, the lungs heal in an abnormal way, with fewer, larger air sacs, thicker airway walls, and small blood vessels that do not grow normally. Because of this, babies need extra oxygen for weeks to months, and they may breathe fast, tire easily, and have trouble feeding and growing. Doctors diagnose BPD when a premature baby still needs oxygen or breathing support at a standard age point after birth (commonly at 36 weeks post-menstrual age), and they grade the severity based on how much support is needed. NCBI+2PMC+2

Perinatal bronchopulmonary dysplasia (BPD) is a long-term lung condition that happens in very premature babies who needed oxygen or a breathing machine in the first weeks of life. Their lungs are still developing, and the extra oxygen and pressure, plus infections and inflammation, can slow normal lung growth. Modern BPD looks less like scarring and more like lungs that did not fully develop the tiny air sacs and blood vessels. Doctors diagnose BPD based on how much breathing support a baby still needs at a set age (usually 36 weeks post-menstrual age), and they grade it by severity. BPD can lead to fast breathing, feeding trouble, poor growth, and later wheeze or pulmonary hypertension. PubMed+2atsjournals.org+2

Other names

Doctors may also call this condition: bronchopulmonary dysplasia (BPD), chronic lung disease of prematurity (CLD), neonatal chronic lung disease, or later in childhood, post-prematurity respiratory disease (PPRD) when symptoms and lung function problems continue beyond infancy. MSD Manuals+1

Types

By severity at a standard age point
Doctors often grade BPD by the level of oxygen or respiratory support needed at 36 weeks post-menstrual age. Newer criteria use the amount of support (for example, low-flow oxygen vs. high-flow oxygen vs. positive pressure) to classify severity, because this best predicts later outcomes. This gives practical “grades” rather than just oxygen percentages. PMC

By clinical course
Some infants have mild BPD and wean off oxygen in a few weeks. Others have moderate BPD and need oxygen for several months. A smaller group have severe BPD, needing high-flow oxygen or ventilator support for a long time and may develop pulmonary hypertension (high pressure in the lung blood vessels). Symptoms can continue into childhood as PPRD, with cough, wheeze, and less exercise tolerance. PMC+1

By severity and clinical pattern

Classic (old) BPD vs. “new” BPD. Older infants who got very high oxygen and stiff ventilation had “classic” BPD with airway injury and scarring; today’s extremely preterm infants more often have “new” BPD caused by interrupted lung growth with fewer, larger alveoli and abnormal vessels. PubMed

Severity-based BPD (mild, moderate, severe). Modern grading depends on oxygen/ventilatory needs at 36 weeks PMA. Severe BPD means the baby still needs pressure support or high oxygen. This grading helps predict risks like readmissions and high blood pressure in the lungs. MSD Manuals

BPD with pulmonary hypertension (BPD-PH). Some babies with BPD also develop high pressure in the lung blood vessels, which raises the risk of poor growth and low oxygen. These infants need special monitoring and sometimes heart-lung medicines. AAP Publications

Causes and risk factors

1. Extreme prematurity
   The earlier a baby is born, the more immature the lungs. Immature lungs are easier to injure and do not repair normally. This is the strongest risk factor. NCBI

2. Very low birth weight
   Very small babies (especially <1500 g) have fewer, more delicate air sacs and blood vessels, which raises the risk. MSD Manuals

3. Mechanical ventilation
   Breathing machines can be lifesaving. But pressure and volume can stretch and injure tiny airways (barotrauma/volutrauma) and cause inflammation. MSD Manuals

4. High oxygen exposure
   Extra oxygen helps in the short term but can form reactive oxygen species that irritate and damage the lungs. NCBI

5. Atelectotrauma (repeated collapse and re-opening of air sacs)
   When small airways repeatedly close and re-open, the lining is damaged and inflammation grows. NCBI

6. Infection after birth (sepsis, ventilator-associated infection)
   Germs trigger inflammation that worsens lung injury and delays healing. NCBI

7. Chorioamnionitis (infection/inflammation before birth)
   Inflammation around the baby before birth is linked to a higher risk of BPD. PMC+1

8. Patent ductus arteriosus (PDA)
   A persistent PDA can flood the lungs with extra blood flow and worsen lung injury; prolonged exposure is tied to pulmonary vascular problems in BPD. JAMA Network+1

9. Pulmonary edema and fluid overload
   Extra lung water makes gas exchange harder and increases the need for support. MSD Manuals

10. Poor early nutrition and slow growth
    Lungs need protein, calories, and micronutrients to repair and develop. Poor intake delays healing. MSD Manuals

11. Low vitamin A status
    Preterm babies often lack vitamin A, which is needed for healthy airway and alveolar lining; low vitamin A is linked to higher BPD risk. Cochrane+1

12. Intrauterine growth restriction (IUGR)
    Babies who grew poorly in the womb have smaller, less mature lungs at birth. NCBI

13. Genetic susceptibility
    Some infants may inherit differences in inflammation or repair pathways that raise risk. NCBI

14. Male sex
    Boys have slightly higher BPD risk, possibly due to slower lung maturation. NCBI

15. Multiple gestation (twins, triplets)
    Multiples are often born earlier and smaller, increasing risk. NCBI

16. Lack or delay of antenatal steroids
    Maternal steroids before preterm birth help mature lungs; without them, risk rises. NCBI

17. Ureaplasma and other airway colonization
    Certain organisms colonizing the airway can sustain inflammation. NCBI

18. Reflux with micro-aspiration
    Stomach contents reaching the airway can irritate and inflame lungs. publications.ersnet.org

19. Environmental exposures after discharge (smoke, pollutants)
    Irritants inflame recovering lungs and can trigger setbacks. publications.ersnet.org

20. Repeated respiratory infections
    Each infection can cause a flare of inflammation and slow lung recovery. publications.ersnet.org

Symptoms and everyday signs

1. Fast breathing (tachypnea)
   The baby breathes quickly most of the time because the lungs move less air with each breath. MSD Manuals

2. Working hard to breathe
   You may see chest retractions, head bobbing, or flaring nostrils. These are signs the baby is using extra muscles to pull air in. MSD Manuals

3. Wheezing or noisy breathing
   Small swollen airways can whistle or squeak when air moves through them. NCBI

4. Low oxygen levels
   Without extra oxygen, the saturation can drop, especially during sleep or feeds. MSD Manuals

5. Bluish lips or skin (cyanosis) during stress
   When oxygen is low, the color may change around the lips or face. MedlinePlus

6. Poor feeding
   Breathing fast makes it hard to coordinate suck, swallow, and breathe. Babies may stop often or tire quickly. NCBI

7. Slow weight gain
   Energy goes to breathing work, leaving less for growth. MSD Manuals

8. Sweating with feeds or mild activity
   This can reflect extra breathing effort or heart-lung strain. publications.ersnet.org

9. Frequent cough
   Irritated airways and infections cause cough episodes. PMC

10. Recurrent chest infections
    Fragile lungs are more prone to bronchiolitis and pneumonia. publications.ersnet.org

11. Apnea or pauses in breathing
    Immature respiratory control plus sick lungs can lead to intermittent pauses, especially early on. MSD Manuals

12. High carbon dioxide (CO₂) levels
    Trapped air and weak exhalation can raise CO₂, causing sleepiness or irritability. MSD Manuals

13. Signs of pulmonary hypertension
    Poor oxygen and abnormal vessels can raise lung blood pressure, leading to poor growth, more desaturation, or edema. publications.ersnet.org

14. Need for oxygen for many weeks
    A long need for oxygen is the hallmark sign used in diagnosis. MSD Manuals

15. Longer hospital stay and frequent clinic visits
    Babies may need time to safely wean oxygen and to watch growth and breathing. PMC

Diagnostic tests

(grouped and explained in very simple language)

A) Physical examination (bedside look and listen)

1. Observation of breathing effort
   Clinicians watch the chest for retractions, head bobbing, and nasal flaring. This shows how hard the baby works to breathe. More effort suggests more severe disease. MSD Manuals

2. Breathing rate count
   A high rate at rest suggests the lungs are stiff or the airways are narrow. Tracking the trend helps judge progress. MSD Manuals

3. Auscultation with a stethoscope
   The doctor listens for wheeze, crackles, or decreased breath sounds. These sounds point to swollen airways, congestion, or uneven air entry. NCBI

4. Growth check (weight, length, head size)
   Poor gain often means breathing is consuming calories or feeding is hard. Growth is a key marker of overall control. publications.ersnet.org

5. Color and perfusion check
   Bluish color or cool hands/feet may suggest low oxygen or circulation strain. MedlinePlus

B) Manual/bedside functional tests (simple tools done at the crib or clinic)

6. Spot pulse oximetry
   A small probe on the hand or foot shows oxygen saturation. Values guide oxygen needs and are checked awake, asleep, and during feeds. MSD Manuals

7. Overnight (or nap) oximetry trend
   A longer recording catches dips during sleep. It helps decide if home oxygen is still needed or can be reduced safely. PMC

8. Feeding assessment with saturation monitoring
   Clinicians watch the baby feed while tracking oxygen. Drops suggest the baby still needs oxygen support or pacing during feeds. PMC

9. Clinical scoring of work of breathing
   Simple bedside scores (e.g., retraction/nasal flare counts) help compare days and guide changes in support. PMC

C) Laboratory and pathological tests

10. Arterial or capillary blood gas
    Measures oxygen, carbon dioxide, and acidity (pH). It shows if the baby is hypoxemic or retaining CO₂ and helps set ventilator or oxygen levels. MSD Manuals

11. Complete blood count (CBC)
    Looks for anemia (low red cells) that can worsen oxygen delivery, or high white cells that suggest infection. NCBI

12. C-reactive protein and cultures when ill
    Check for inflammation or infection during flares; infection treatment can ease breathing work. NCBI

13. Electrolytes and kidney function
    Many babies receive diuretics; labs help watch for low sodium or potassium and adjust doses. MSD Manuals

14. Brain natriuretic peptide (BNP or NT-proBNP)
    A blood marker that can rise with pulmonary hypertension or right-heart strain; it supports echo findings. publications.ersnet.org

15. Viral testing during wheezy episodes
    Identifies RSV or other viruses that often trigger setbacks in infants with BPD. publications.ersnet.org

D) Electrodiagnostic / physiologic monitoring

16. Electrocardiogram (ECG)
    Records heart rhythm and can show right-heart strain that may happen with pulmonary hypertension in severe BPD. publications.ersnet.org

17. Capnography (end-tidal CO₂ monitoring)
    Non-invasive check of CO₂ during ventilation or high-flow therapy; helps see if ventilation is enough. MSD Manuals

18. Sleep study (polysomnography) in selected infants
    Looks for sleep-related breathing problems and oxygen dips; guides safe weaning from oxygen and discharge planning. PMC

E) Imaging tests

19. Chest X-ray
    Common, quick test. In BPD, it may show patchy areas, overinflation, and streaky or bubbly changes. It also checks for complications like pneumonia or air-leak. MSD Manuals

20. Echocardiography (heart ultrasound)
    Very important to screen for pulmonary hypertension, a serious complication in moderate–severe BPD. Echo guides treatment and follow-up. publications.ersnet.org

Additional imaging sometimes used:

1. Lung ultrasound to look for fluid and aeration patterns at the bedside, and high-resolution chest CT in complex cases to map airway and lung structure; these are reserved for special situations because of expertise needs (ultrasound) and radiation (CT). publications.ersnet.org

Non-pharmacological treatments (therapies & other care)

1. Gentle ventilation (volume-targeted, low pressures). Purpose: support breathing while protecting fragile lungs. Mechanism: limits over-stretching (volutrauma) and pressure injury (barotrauma), reducing inflammation that drives BPD. Early extubation to CPAP/HFNC is encouraged when safe. PMC

2. Early CPAP and avoidance of invasive ventilation. Purpose: keep air sacs open without a tube. Mechanism: CPAP maintains functional residual capacity and reduces atelectotrauma; less time on a ventilator lowers BPD risk. PMC

3. Targeted oxygen saturation ranges. Purpose: give enough oxygen for growth but avoid excess that harms lungs and eyes. Mechanism: preventing hyperoxia reduces oxidative stress and inflammation. Units use written SpO₂ targets and alarms. MSD Manuals

4. Surfactant therapy with minimally invasive techniques (LISA/INSURE) for RDS. Purpose: treat early surfactant lack to cut ventilation time. Mechanism: restores alveolar surface tension, improves oxygenation, and may reduce ventilator injury. FDA Access Data

5. Strict infection-prevention bundles. Purpose: lower sepsis and ventilator-associated infections that worsen BPD. Mechanism: hand hygiene, line care, closed suction, and early extubation lower inflammation triggers. PMC

15. Early PDA management (medical or procedural) when hemodynamically significant. Purpose: improve lung mechanics by reducing pulmonary over-circulation. Mechanism: closing a large PDA lowers lung edema and oxygen demand. FDA Access Data+1

16. Standardized bronchiolitis/viral prevention (palivizumab if eligible). Purpose: prevent severe RSV that can worsen BPD. Mechanism: monthly monoclonal antibody reduces RSV hospitalization in high-risk infants. FDA Access Data

17. Family education and discharge planning (home oxygen as needed). Purpose: safe transition home with growth and therapy plans. Mechanism: caregiver training reduces readmissions and supports development. MSD Manuals

18. Physical/occupational/speech therapy for feeding and tone. Purpose: improve oral feeding and muscle coordination. Mechanism: targeted exercises and pacing reduce aspiration risk and support growth. MSD Manuals

19. Avoid routine chest physiotherapy. Purpose: prevent harm. Mechanism: routine percussive therapy has not shown benefit in BPD and may destabilize infants; use only for specific indications. NCBI

20. Multidisciplinary BPD care team & follow-up clinic. Purpose: coordinate lung, heart, nutrition, and neurodevelopment care. Mechanism: team-based protocols improve adherence and outcomes. AAP Publications

When to see doctors

Parents/caregivers should seek medical care urgently if a baby has faster breathing than usual, chest retractions, bluish lips/skin, poor feeding, vomiting with cough, pauses in breathing, fever or suspected infection, or is using more home oxygen. Routine follow-up with neonatology, pulmonology, cardiology (if PH risk), nutrition, and developmental specialists is important because needs change as the baby grows. Vaccination and RSV prevention schedules should be kept current. AAP Publications+1

---

What to eat and what to avoid

What to “eat” (receive): human milk with the right fortification; enough protein, calories, vitamins (A, D), iron, calcium/phosphate, zinc; gradual progression to safe oral feeds with therapist guidance. This supports lung repair, growth, and immunity. PMC+1

What to avoid (or use only if clearly needed): unnecessary extra fluids; high-dose DHA to prevent BPD (no benefit); exposure to smoke and indoor pollutants; overuse of acid-suppressing drugs without diagnosis; sick contacts during viral season; missed vaccines/RSV prophylaxis; home oxygen changes without a plan. nutrition.bmj.com+1

Frequently asked questions

1) What causes BPD?
A mix of very early birth, inflammation, oxygen/pressure exposure, infections, and poor growth interrupt lung development. PubMed

2) Is BPD permanent?
Many babies improve over months to years as lungs grow new air sacs and vessels, but some have lasting wheeze or exercise limits. MSD Manuals

3) How is BPD diagnosed?
By the need for oxygen/pressure support at around 36 weeks PMA, with grading by severity. MSD Manuals

4) Does caffeine cure BPD?
No. It supports breathing and earlier extubation, which may lower risk, but it isn’t a cure. FDA Access Data

5) Are steroids safe?
They can help some babies wean from the ventilator but have risks; teams use the lowest effective dose in selected infants. PubMed

6) Should every baby get inhaled nitric oxide?
No. Routine use in very preterm infants isn’t recommended; it’s a rescue therapy in special cases. AAP Publications

7) Can vitamins prevent BPD?
Vitamin A can modestly reduce risk in very high-risk infants; other supplements support growth but don’t replace good respiratory care. nejm.org

8) Why is growth so important?
Lungs need protein, calories, and minerals to build new tissue; poor growth predicts worse outcomes. PMC

9) What about azithromycin?
It can clear Ureaplasma in trials, but routine preventive use is still being studied; doctors target it in selected cases. PubMed

10) Does closing a PDA help?
If the PDA is large and causing lung over-circulation, medical or procedural closure can improve breathing and oxygen needs. FDA Access Data

11) Will my baby go home on oxygen?
Some do; teams create a home plan with flow targets, monitors, and follow-up to wean safely. MSD Manuals

12) Is BPD-associated pulmonary hypertension common?
It occurs in a subset of infants with moderate-severe BPD and needs echocardiography-based screening and tailored treatment. AAP Publications

13) Are there stem-cell cures?
Not yet. MSCs and related therapies are experimental and available only in research settings. SpringerLink

14) Which vaccines matter most?
All routine vaccines plus RSV prevention (palivizumab if eligible) help avoid infections that worsen BPD. FDA Access Data

15) What’s the long-term outlook?
Most children improve with time and support; early therapy, nutrition, and careful follow-up make the biggest difference. MSD Manuals
