Bronchiolitis is one of the most common reasons infants are admitted to pediatric units, and most of what helps them get better is nursing care, not medication. The bedside priorities are steady respiratory assessment, hydration, gentle airway clearance, and knowing when to escalate.
What you are watching for
Bronchiolitis is a viral lower respiratory tract infection in infants and young children, most often caused by respiratory syncytial virus (RSV). It typically presents with a few days of upper respiratory symptoms followed by cough, wheeze, crackles, increased work of breathing, and feeding difficulty. Diagnosis is clinical, based on history and physical exam, and severity is judged the same way. Routine viral testing and chest radiographs are not needed to make the diagnosis in a typical case.
Your serial assessment is the real monitor. Track respiratory rate over a full minute, work of breathing (nasal flaring, retractions, head bobbing, grunting), color, mental status, and feeding. Auscultate for air movement, not just wheeze. A quieter chest with rising effort can mean fatigue, not improvement. Because the illness fluctuates and young infants tire, trend your findings rather than relying on a single snapshot.
Apnea is a recognized and dangerous presentation, especially in young, premature, or low-birthweight infants. Treat new apnea, worsening retractions, grunting, lethargy, or poor perfusion as escalation triggers and notify the provider per your facility's process.
Oxygen, suction, and hydration at the bedside
These three supportive measures are the core of inpatient care, and they are largely nurse-driven within facility protocol.
Oxygen. Both the AAP guideline and NICE support a conservative approach to supplemental oxygen. NICE recommends giving oxygen when saturation is persistently below 92 percent. The AAP guideline allows clinicians to withhold supplemental oxygen when saturation is at or above 90 percent in otherwise well infants, and discourages reliance on continuous pulse oximetry in stable, non-hypoxic patients. Continuous oximetry can drive overtreatment and prolonged stays when brief, self-resolving desaturations are chased. Follow your unit's monitoring orders, weight the whole clinical picture over the number, and avoid waking a comfortably sleeping infant for a transient dip.
Suction. Infants are preferential nasal breathers, so clearing the nose can meaningfully ease breathing and feeding. Both AAP and NICE advise against routine deep suctioning. NICE supports upper airway suctioning when there is respiratory distress or feeding difficulty from secretions, and recommends suctioning for any infant presenting with apnea even without obvious secretions. Use saline drops with bulb or gentle catheter suction; time it before feeds and reassess afterward.
Hydration. Tachypnea and nasal congestion make feeding hard, and dehydration is a common reason these infants need admission. Assess intake, wet diapers, mucous membranes, and weight. For infants who cannot safely feed by mouth, the AAP guideline supports either nasogastric or intravenous fluids. Enteral feeding by NG tube is often well tolerated; coordinate the route with the team, and watch closely for aspiration risk and worsening effort during feeds.
What not to expect to give
A frequent point of patient and family education is explaining what is deliberately not part of care. Across AAP and StatPearls, the evidence does not support routine use of several familiar interventions:
- Bronchodilators (albuterol) should not be used routinely.
- Systemic corticosteroids are not recommended for typical bronchiolitis.
- Nebulized epinephrine is not recommended for routine inpatient treatment.
- Antibiotics are reserved for a documented bacterial co-infection, not the viral illness itself.
- Chest physiotherapy is not recommended.
Most bronchiolitis care is supportive. The skill is in the assessment, the timing, and the teaching, not in escalating to medications that do not help.
Framing this clearly helps families who expect a treatment understand that close monitoring and supportive care are the appropriate plan, and reduces pressure to push for antibiotics.
Infection control, education, and discharge
RSV and the other viruses spread readily on a pediatric unit. Hand hygiene is the single most effective prevention measure; reinforce it with every contact and with families, and follow facility contact and droplet precautions. The AAP guideline also emphasizes counseling families to keep infants away from tobacco smoke, which raises both risk and severity.
Build discharge teaching from the same fundamentals. Teach caregivers saline and bulb suctioning, small frequent feeds, and how to count wet diapers as a hydration check. Most importantly, teach the return-precautions in plain language: fast or labored breathing, flaring or chest retractions, bluish color of lips or skin, poor feeding or far fewer wet diapers, and an infant who is unusually sleepy or hard to rouse. MedlinePlus offers caregiver-level wording you can adapt, and pairing the verbal teaching with written instructions improves recall.
Document the serial picture, not just vitals: work of breathing, feeding tolerance and intake, suction and oxygen interventions with the response, and the specific warning signs you taught and the caregiver's teach-back. That trended record is what lets the next nurse and the provider see the trajectory and act before a tiring infant decompensates.
