3 Pediatric Respiratory Distress

Recognize distress and failure

Respiratory distress means a child is working harder than normal to breathe but is still maintaining breathing. Signs can include breathing faster or slower than expected for age, nasal flaring, grunting, head bobbing in infants, retractions, noisy breathing, difficulty speaking, feeding, or crying because of breathlessness, and restlessness, anxiety, or unusual discomfort.

Respiratory failure occurs when breathing can no longer adequately maintain oxygenation, remove carbon dioxide, or both. Warning signs include worsening fatigue, weak or irregular breathing, poor air movement, pauses or gasping, reduced responsiveness, and blue or gray lips or face. Respiratory failure can progress to respiratory arrest.

A child who becomes quieter or appears less distressed is not necessarily improving: decreasing effort can signal exhaustion. Do not wait for cyanosis, which may be a late sign.

Assess breathing systematically

Use a rapid, systematic assessment and repeat it after every intervention. Consider the child’s overall condition rather than relying on a single measurement.

1. Observe overall appearance. Check whether the child is alert and interacting or becoming drowsy, limp, or difficult to arouse. Look for abnormal color and signs of exhaustion.

2. Count and assess breathing. Observe rate, depth, rhythm, chest rise, and effort. Count for a full minute when feasible, especially in infants or when breathing is irregular. Interpret the rate in context of age, activity, fever, and overall condition; one number alone does not establish severity.

3. Look for work of breathing. Check for retractions, nasal flaring, grunting, head bobbing, or inability to feed or speak normally.

4. Listen to sound and airflow. Note stridor, wheezing, crackles, or unusually quiet breath sounds. Minimal sound with poor chest movement can indicate critically reduced airflow.

5. Check circulation and oxygenation. Assess pulse, skin color, and perfusion. Use pulse oximetry when available, but interpret the reading alongside appearance and breathing. Device and patient factors can affect the reading, and it should not override signs of serious illness.

6. Consider the cause. Briefly ask about onset, choking, illness, allergy, asthma, medicines, or injury, without delaying urgent airway or breathing support.

Provide initial support

Call for help early when distress is severe or worsening, or is accompanied by altered mental status, poor air movement, or abnormal breathing. Arrange emergency evaluation and transport as appropriate.

Keep the child calm and in a position of comfort. Avoid unnecessary handling or forcing the child to lie flat; allow a caregiver to remain close if this helps the child settle.

Open and maintain the airway using an age-appropriate airway-opening maneuver if trained. If spinal injury is suspected, use a jaw thrust first. If it does not open the airway, airway patency takes priority. Clear visible material and suction secretions when trained and equipped. Do not perform blind finger sweeps for suspected choking.

Give oxygen when indicated and available, following local protocol and monitoring the child’s response. Do not delay ventilation to set up oxygen if breathing is absent or inadequate.

Support inadequate breathing

If the child has a pulse but absent or inadequate respiratory effort, trained rescuers should provide assisted breaths with a mask and bag when available. The 2025 American Heart Association guidance recommends $1$ breath every $2$–$3$ seconds for infants and children with a pulse who need rescue breathing. Use only the volume needed to produce visible chest rise. Reassess frequently and follow current training and local protocols.

Treat only within your training and protocol. Prescribed or protocol-directed inhaled medicines may be appropriate for some causes of wheezing, but they do not replace assessment, escalation, or ventilation support when needed.

If the child becomes unresponsive and is not breathing normally, activate emergency response and begin pediatric CPR according to current training and local guidance.

Reassess and escalate

Repeat the assessment after every intervention and continue reassessing. Increased effort, poor air movement, fatigue, and changes in alertness are important warning signs. A child who is tiring or becoming less responsive may be progressing from distress to failure even if visible struggle decreases.

Look at the child before relying on a monitor or a single vital sign. Keep the child calm, support the airway, provide oxygen when indicated, and assist ventilation when breathing is inadequate. Escalate early and follow local emergency protocols and your level of training.
