Retaining a Pediatric Pulmonology Expert Witness: What Attorneys Need to Know

1. Why ICU-Based Expertise Matters More Than Outpatient Credentials

Most pediatric pulmonologists spend the majority of their clinical time in outpatient settings — managing asthma action plans, monitoring CF lung function over years, adjusting inhaler regimens, and following premature infants with chronic lung disease through early childhood. This is valuable, important work. But it is not where pediatric pulmonary malpractice cases are born.

Litigation arises at the acute end of the spectrum — when a child with known asthma stops responding to bronchodilators, when a child with cystic fibrosis decompensates faster than anticipated, when a technology-dependent child on a home ventilator arrives in the emergency department in respiratory failure. These are ICU events. The standard of care at issue is set by what happens in the emergency department and the pediatric intensive care unit, not what was documented in a quarterly outpatient pulmonology visit six months earlier.

An outpatient pediatric pulmonologist who rarely or never manages critically ill children has a fundamental limitation in these cases: they can speak to the chronic disease trajectory, but they cannot credibly testify about what should have happened in the acute setting. Cross-examination will expose this gap quickly.

The pediatric intensivist with dual subspecialty certification in pulmonology occupies a distinctly different position. Daily management of critically ill children with acute and chronic pulmonary conditions — on mechanical ventilators, high-frequency oscillators, and non-invasive support — produces an expert who can address both the chronic disease context and the acute management failures that actually generated the litigation. That combination is rare, and it is what makes it credible.

2. Conditions Most Commonly at Issue in Pediatric Pulmonary Malpractice Cases

Pediatric pulmonary malpractice cases cluster around a recognizable set of conditions. The clinical specifics of each disease process generate different legal theories, different standard-of-care questions, and different expert requirements. Understanding which condition is at the center of your case is the starting point for expert selection.

3. Severe and Near-Fatal Asthma

Asthma is the most common chronic disease in children, and near-fatal asthma attacks remain a significant source of pediatric emergency department and PICU malpractice claims. The cases that generate litigation usually involve one of two patterns: a child whose acute deterioration was not recognized quickly enough, or a child whose deterioration was recognized but managed below the standard of care.

Standard of care issues in severe asthma litigation

• Triage and recognition: Appropriate use of clinical asthma severity scores (PRAM, PASS), objective measures of airflow limitation, and escalation thresholds. Failure to recognize a child in impending respiratory failure despite objective signs — prolonged expiratory phase, silent chest, accessory muscle use, altered mental status — is one of the most common theories in fatal asthma cases.
• Initial bronchodilator therapy: The standard of care for severe acute asthma in children requires continuous albuterol nebulization, early ipratropium, systemic corticosteroids, and consideration of adjunct therapies (magnesium sulfate, heliox) within a defined time window. Gaps in any of these elements are documentable standard-of-care failures.
• Intubation decision: The decision to intubate a child in status asthmaticus is one of the highest-stakes judgment calls in pediatric emergency medicine. Delayed intubation in a child who has developed respiratory failure is a recurring theory in fatal asthma cases. Premature intubation in a child who did not require it — exposing the child to the well-known risks of mechanical ventilation in asthma — is a viable defense theory.
• Ventilator management in intubated asthma: Children with status asthmaticus who require mechanical ventilation are at extreme risk of dynamic hyperinflation, tension pneumothorax, and cardiovascular collapse if ventilated incorrectly. A permissive hypercapnia strategy with long expiratory times, low respiratory rates, and careful attention to intrinsic PEEP is the standard. Errors in this domain can be immediately fatal.

4. Cystic Fibrosis

Cystic fibrosis litigation is distinct from other pediatric pulmonary cases in one important way: it almost always involves a child with an established, documented clinical relationship with a CF care team. The medical record is extensive. The baseline is known. When something goes wrong acutely, the departure from baseline — and whether that departure was recognized and addressed appropriately — is the central question.

Pulmonary exacerbations

The most common source of CF litigation involves pulmonary exacerbations — episodes of acute worsening in lung function, increased sputum production, and systemic symptoms that require treatment escalation. The key standard-of-care questions in exacerbation cases are: Was the exacerbation recognized promptly? Was antibiotic therapy appropriate for the patient's known bacterial flora (particularly Pseudomonas aeruginosa and methicillin-resistant Staphylococcus aureus)? Was IV therapy initiated when oral therapy failed? Was the patient's decline assessed with objective lung function measures?

Hemoptysis

Massive hemoptysis — life-threatening bleeding from the airways — is a known complication of advanced CF lung disease. Failure to recognize hemoptysis severity, inappropriate management decisions (positioning, airway management), or failure to escalate to bronchial artery embolization in a timely manner are potential theories of liability in CF hemoptysis cases.

CF-related pulmonary hypertension

Advanced CF lung disease is associated with pulmonary hypertension, a complication that significantly worsens prognosis and requires specific management considerations. An expert in CF must be able to opine on whether pulmonary hypertension was appropriately screened for, recognized, and incorporated into acute management decisions.

5. Bronchopulmonary Dysplasia

Bronchopulmonary dysplasia (BPD) — chronic lung disease of prematurity — develops in premature infants who require prolonged respiratory support after birth. It is the most common chronic lung disease of infancy, and its management spans from the NICU through early childhood. BPD cases in litigation may involve the initial NICU management, the discharge planning process, or acute decompensation events in infants and toddlers with established BPD.

NICU oxygen management

The relationship between oxygen exposure and BPD development is well-established. Hyperoxia in premature infants is injurious to developing lung tissue and directly contributes to BPD severity. Appropriate oxygen targeting — maintaining SpO2 within evidence-based ranges — is a standard of care that has evolved significantly over the past two decades. Expert testimony in NICU oxygen management cases must reflect the standards in effect at the time of the clinical events, not current practice.

BPD severity and pulmonary hypertension

The 2019 revised BPD severity classification (Jobe and Bancalari criteria, updated) provides a framework for understanding BPD severity and its implications for management. Severe BPD — particularly when complicated by pulmonary hypertension — requires specific monitoring (echocardiography, right heart evaluation) and treatment that standard general pediatric practice may miss. Failure to recognize and treat BPD-associated pulmonary hypertension is a recurring theory in cases involving infants with severe BPD who decompensate acutely.

Discharge planning and home support

Premature infants with BPD who are discharged on supplemental oxygen, home monitoring, or other respiratory support require detailed discharge planning, family education, and follow-up arrangements. Cases involving infants who deteriorate after discharge may implicate the adequacy of the discharge plan, the clarity of instructions given to caregivers, and the accessibility of appropriate follow-up.

6. Technology-Dependent Children on Home Ventilators

Children who are discharged from the hospital on mechanical ventilation — typically via tracheostomy — represent one of the most medically complex patient populations in pediatrics. They have a range of underlying conditions: severe BPD, congenital central hypoventilation syndrome, spinal muscular atrophy, high cervical spinal cord injuries, and complex congenital heart disease with residual respiratory compromise, among others.

When these children arrive in the emergency department in distress, the clinical situation requires immediate, competent management of both the underlying condition and the technology keeping them alive. The standard of care for managing a technology-dependent child in an acute setting is not general knowledge — it is a subspecialty skill set.

Common theories in technology-dependent patient cases

• Tracheostomy emergencies: Accidental decannulation, tracheostomy obstruction, and false passage creation are known risks in tracheostomy-dependent children. The standard of care for emergency management — including having an appropriately sized replacement tube and a smaller-sized backup at the bedside, and the proper technique for re-establishing airway access — is clearly established and frequently at issue when a child deteriorates from a tracheostomy complication.
• Ventilator alarm management: Failure to respond appropriately to ventilator alarms — in the hospital or at home — is a recurring theory in cases involving technology-dependent children. The adequacy of alarm settings, the training provided to caregivers, and the response protocol at the receiving facility are all potential areas of standard-of-care analysis.
• Acute-on-chronic decompensation: Children with baseline respiratory compromise have dramatically reduced physiologic reserve. What would be a minor respiratory illness in a healthy child — a viral upper respiratory infection, mild aspiration — can be life-threatening in a child on home ventilation. Recognition of acute decompensation in the context of known chronic disease, and appropriately aggressive management, is the standard that must be met.
• Discharge planning adequacy: The standard for safely discharging a technology-dependent child from the hospital includes comprehensive caregiver training, competency assessment, home nursing arrangements, equipment setup and backup, and a clearly defined emergency response plan. Deficiencies in any of these elements — inadequate training, insufficient backup equipment, no emergency protocol — can form the basis of a negligence claim when the child deteriorates at home.

7. Acute Respiratory Failure and ARDS in Children

Pediatric acute respiratory distress syndrome (PARDS) — defined by the Pediatric Acute Lung Injury Consensus Conference (PALICC) criteria — is a common PICU diagnosis with substantial morbidity and mortality. PARDS cases in litigation may arise from a variety of underlying causes: aspiration pneumonia, sepsis-associated lung injury, drowning, inhalation injury, or direct pulmonary infection. The standard-of-care questions center on ventilator management, adjunct therapies, and recognition of the underlying diagnosis.

Lung-protective ventilation

The cornerstone of PARDS management is lung-protective ventilation: limiting tidal volumes to 5–8 mL/kg of ideal body weight, maintaining plateau pressures below 28–30 cmH2O, and using positive end-expiratory pressure (PEEP) to prevent repetitive alveolar collapse. Departure from these parameters — particularly the use of high tidal volumes or inadequate PEEP — is a well-established, evidence-based standard-of-care failure that has generated significant malpractice litigation in both adult and pediatric ICU settings.

Adjunct therapies

For children with severe PARDS, adjunct therapies — prone positioning, inhaled nitric oxide, high-frequency oscillatory ventilation, and ultimately ECMO — represent an escalating ladder of intervention with specific evidence-based indications. Failure to implement prone positioning in a child with refractory hypoxemia on conventional ventilation, or failure to consider ECMO in a child with an oxygenation index above 40 despite optimal management, are increasingly recognized as standard-of-care issues in severe PARDS.

8. Selecting the Right Expert for Your Pediatric Pulmonary Case

The right pediatric pulmonology expert for your case depends on precisely where the alleged negligence occurred. Not all pediatric pulmonary cases require the same expertise — and the mismatch between the expert's clinical background and the setting where the negligence occurred is one of the most exploitable vulnerabilities in cross-examination.

Match the expert to the clinical setting

• If the negligence occurred in the outpatient setting — a missed diagnosis during a clinic visit, failure to escalate chronic therapy, inadequate follow-up — an outpatient pediatric pulmonologist may be the appropriate choice.
• If the negligence occurred in the emergency department or inpatient setting — failure to recognize severity, inadequate acute management, intubation decision errors, ventilator management — the expert must have current, active practice managing these patients in an acute care environment. An outpatient specialist who rarely or never manages intubated patients cannot speak credibly to the inpatient standard of care.
• If the negligence spans both settings — a child with known chronic disease who was inadequately managed in outpatient follow-up AND then mismanaged acutely — you may need an expert who can address both, or two experts with distinct roles.

Questions to ask before you retain

1. How frequently do you manage children with this condition in an acute or critical care setting?
2. When did you last manage an intubated child with status asthmaticus? A child on HFOV for PARDS? A child with a tracheostomy emergency?
3. Are you comfortable testifying about ventilator management decisions, not just outpatient disease management?
4. Are you familiar with the PALICC PARDS criteria, the revised BPD classification, and the current CF exacerbation treatment guidelines?
5. What is your plaintiff/defense split? How many pulmonary-specific cases have you reviewed?
