The School Health Office Asthma Exacerbation

Classification: moderate-to-severe exacerbation.

• SpO2 90% on room air, speaking in 3- to 4-word phrases, retractions and nasal flaring, PEF 50% of personal best. Any one of these is concerning; together they are not a 'nebulize and see' situation.

First 20 minutes, in order:

1. Oxygen by mask or nasal cannula titrated to keep SpO2 at or above 92–94%. Do not wait for the first bronchodilator dose to start oxygen.
2. Short-acting bronchodilator immediately: albuterol 2.5 mg nebulized, or 4 to 8 puffs of MDI with a spacer. A spacer with an MDI is equivalent to a nebulizer in this setting. Repeat every 20 minutes for up to three doses.
3. Ipratropium 0.5 mg nebulized with each of the first three albuterol treatments. This reduces hospitalization risk in moderate-to-severe exacerbations.
4. Systemic corticosteroid within the first hour: prednisolone 1 to 2 mg/kg orally (maximum 60 mg), or dexamethasone 0.6 mg/kg (maximum 16 mg). Steroids take hours to work, which is exactly why they are given now, not after the third nebulizer.
5. Continuous monitoring: pulse oximetry, heart rate, respiratory rate, and work of breathing. Sit him upright. Stay with him.
6. Reassess after each dose for air entry, retractions, speech, and mental status. A quiet chest in a child who was wheezing is deterioration, not improvement.

Transport policy:

Call 911 as soon as you recognize the severity. A school policy about parent contact cannot override an oxygen saturation of 90% with retractions. The nurse calls the parent while the ambulance is being dispatched and documents that the clinical decision preceded parental notification. Call the emergency department to give a report and call the parent a second time once the ambulance is underway.

Reassess after roughly 60 minutes (three bronchodilator doses) and decide on objective criteria, not on how he looks in the doorway.

Criteria suggesting a good response and possible discharge:

• SpO2 at or above 92–94% on room air, sustained through a 60-minute observation period after the last treatment.
• PEF at or above 70% of personal best (at least about 154 L/min for him) and holding there.
• Minimal retractions, full sentences, no nasal flaring, normal mental status.
• He can tolerate oral intake and has no vomiting.

Criteria mandating emergency department transfer:

• Persistent SpO2 below 92% on room air, or oxygen requirement that does not resolve.
• PEF below 70% of personal best after three treatments, or falling.
• Ongoing moderate-to-severe retractions, accessory muscle use, or inability to speak in sentences.
• Drowsiness, agitation, or a decreasing level of consciousness.
• Any prior history of intensive care admission, intubation, or a recent emergency visit or oral steroid course - these shift the threshold toward transfer.

For this child specifically: with an initial SpO2 of 90% and PEF at 50%, the pre-test probability of needing the emergency department is high. Treat and reassess, but have the ambulance arranged in parallel. Do not let a transient bump in saturation after the first nebulizer talk you out of the transport that the initial numbers called for.

If he does go home: prescribe a short oral steroid course, provide a written asthma action plan, arrange follow-up in 24 to 48 hours, and confirm a working inhaler and spacer at home before he leaves.

The root cause is the regimen, not the cold.

• SABA-only treatment with no controller in a 7-year-old with this degree of impairment. Frequent albuterol use is a marker of uncontrolled asthma and a risk factor for death.
• No written action plan. The mother was improvising 'a few puffs when he coughs.'

Education, taught with teach-back:

• Controller vs. reliever. Albuterol opens the airway for hours; an inhaled corticosteroid treats the inflammation that causes the flare. Give the controller daily even when he feels well.
• Inhaler and spacer technique, demonstrated and returned by the child and the caregiver. A school-age child can use a spacer independently with coaching.
• Action plan in green/yellow/red zones with PEF numbers specific to his personal best of 220 L/min.
• When to call 911 and when to go to the emergency department.
• Influenza vaccine and avoidance of tobacco and vape exposure.
• Referral for spirometry and a formal asthma control assessment (for example the Childhood Asthma Control Test) to determine whether the controller step needs adjusting.

Advocacy and care coordination:

• Request a school 504 plan so he can carry or access a quick-relief inhaler, receive treatments during the day, and have the action plan on file with the school nurse.
• Ensure a spacer and albuterol are stocked at school and that the medication authorization form is current.
• Ask about cost and access: a family that cannot fill the controller prescription will be back. Check coverage, use manufacturer programs, and connect them with a care coordinator.
• Document the missed controller and the new plan, and communicate it to the primary care provider the same day.
