Apnea means "without breathing." It is a pause in breathing that lasts longer than the normal brief pauses that occur during sleep.
| Type | Definition | Significance |
|---|---|---|
| Brief pause | Less than 10 seconds | Normal, especially in sleep |
| Apnea | 20 seconds or more (preterm) OR 15 seconds or more (full-term) | Abnormal; requires evaluation |
| Any pause with color change | Any duration with cyanosis, pallor, or bradycardia | Always abnormal |
An unexplained episode of cessation of breathing for:
- 20 seconds or more in a premature infant
- 15 seconds or more in a full-term infant
- ANY duration if associated with:
- Bradycardia (slow heart rate less than 100 bpm)
- Cyanosis (blue color)
- Pallor (pale color)
- Marked hypotonia (floppy, limp baby)
Apnea is a SYMPTOM, not a disease. It always has an underlying cause that must be identified and treated. Do not just treat the apnea; hunt for the etiology!
Definition: Apnea caused by failure of the brain to send signals to the breathing muscles.
Mechanism:
BRAIN (respiratory center) ➔ NO SIGNAL SENT ➔ Breathing muscles don't contract ➔ NO BREATHING
- No respiratory effort (chest doesn't move)
- No airflow through nose/mouth
- May see brief body movements
- Often associated with bradycardia
| Common Cause | Explanation | Common in |
|---|---|---|
| Immature CNS | Brainstem respiratory centers not fully developed | Premature infants |
| Head trauma | Brain injury affecting respiratory centers | Accidents, non-accidental injury |
| Seizures | Seizure activity suppresses breathing | Epilepsy, febrile seizures |
| Sepsis | Infection affects brain function | Any age; especially neonates |
| Toxins/Drugs | Medications suppress respiratory drive | Opioids, sedatives, anesthesia |
| Hypoglycemia | Low blood sugar affects brain | Diabetic mothers' babies, sepsis |
| Intracranial hemorrhage | Bleeding in brain | Premature infants, trauma |
| Congenital CNS malformations | Brain structure abnormalities | Present from birth |
Definition: Apnea caused by blockage of the airway, despite the brain sending signals to breathe.
Mechanism:
BRAIN sends signal ➔ Breathing muscles contract ➔ AIRWAY IS BLOCKED ➔ NO AIRFLOW despite effort
- Respiratory effort present (chest moves, but no air passes)
- May see paradoxical breathing (chest in, belly out)
- Often associated with snoring or noisy breathing
- Common during sleep
| Common Cause | Explanation | Common in |
|---|---|---|
| Adenotonsillar hypertrophy | Enlarged tonsils and adenoids block airway | 2-8 years old |
| Obstructive Sleep Apnea (OSA) | Repeated airway collapse during sleep | Overweight children; enlarged tonsils |
| Laryngomalacia | Floppy larynx collapses during inspiration | Infants; improves with age |
| Foreign body | Object lodged in airway | Toddlers (exploring age) |
| Nasal congestion | Blocked nose prevents breathing | Infants (obligate nose breathers) |
| Micrognathia/Pierre Robin | Small jaw pushes tongue backward | Newborns |
| Choanal atresia | Back of nose is blocked | Newborns (cannot breathe when feeding) |
| Secretions | Mucus or blood blocks airway | Post-surgery; infections |
| Vocal cord paralysis | Vocal cords don't open properly | Birth trauma; surgery |
Definition: Combination of both central and obstructive components.
- Starts as central apnea (no effort), followed by obstructive apnea (effort but no airflow)
- OR starts as obstructive, then becomes central
- Most common type in premature infants
- Premature infants with nasal congestion
- Infants with gastroesophageal reflux (GERD)
- Sedated patients with adenotonsillar hypertrophy
- Infants with upper respiratory infections
Incidence: Very common in premature infants
- Less than 28 weeks gestation: Approx 80-90%
- 28-32 weeks: Approx 50%
- 32-35 weeks: Approx 20%
- More than 35 weeks: Rare
Usually resolves by 36-40 weeks corrected gestational age.
Before 28 weeks: May persist longer; associated with prolonged hospitalization.
Very rare.
If present, ALWAYS indicates underlying disease. Requires thorough investigation.
- Prevalence: 1-5% of children.
- Gender: Boys greater than Girls (ratio 3:1 to 5:1).
- Peak age: 2-8 years (when tonsils are largest relative to airway).
- Risk factors: Obesity, Down syndrome, craniofacial abnormalities, neuromuscular disorders.
Respiratory viral bronchiolitis: 1.2-23.8% develop apnea.
Higher risk: Younger infants (less than 3 months), premature history, RSV infection.
Higher incidence in children with: Cerebral palsy, Muscular dystrophy, Spinal muscular atrophy, Congenital myopathies.
- Immature Central Nervous System:
- Why preemies are at risk: Respiratory center in brainstem not fully developed. Chemoreceptors (sensors for O2 and CO2) immature.
- Response to hypoxia is paradoxical: preemies may STOP breathing instead of breathing faster.
- Risk decreases as baby matures; usually resolves by term equivalent age.
- Central Nervous System Injury:
- Birth asphyxia: Lack of oxygen during delivery damages brain.
- Intraventricular hemorrhage (IVH): Bleeding in brain ventricles (common in preemies).
- Hypoxic-ischemic encephalopathy (HIE): Brain injury from oxygen deprivation.
- Head trauma: Accidental or non-accidental (child abuse).
- Meningitis/Encephalitis: Infection of brain or its coverings.
- Metabolic Disturbances:
- Hypoglycemia (low blood sugar), Hypocalcemia (low calcium), Hyponatremia (low sodium), Severe acidosis (too much acid in blood), Hyperbilirubinemia (very high bilirubin leading to kernicterus).
- Seizures:
- Post-ictal apnea (after seizure). Seizure activity itself can suppress breathing. Subtle seizures in neonates may present only as apnea.
- Toxins and Medications:
- Opioids (Morphine, pethidine, codeine), Sedatives (Diazepam, phenobarbital), Anesthetics (General anesthesia), Prostaglandin E1 (Used for congenital heart disease), Magnesium sulfate (If levels too high).
- Infections:
- Sepsis (Overwhelming infection), Meningitis (Infection of brain coverings), Necrotizing enterocolitis / NEC (Gut infection in preemies).
- Adenotonsillar Hypertrophy: Most common cause of OSA in children. Tonsils and adenoids grow rapidly between 2-8 years. Can completely block airway during sleep when muscles relax. Treatment: Tonsillectomy and adenoidectomy (T&A).
- Obesity: Fat deposits around neck and airway. Increased risk of airway collapse during sleep. Growing problem globally.
- Craniofacial Abnormalities:
- Down syndrome: Midface hypoplasia, macroglossia, hypotonia.
- Pierre Robin sequence: Micrognathia (small jaw), glossoptosis (tongue falls back), cleft palate.
- Craniosynostosis: Premature fusion of skull bones.
- Neuromuscular Disorders: Weak airway muscles cannot keep airway open (e.g., Cerebral palsy, muscular dystrophy).
- Laryngomalacia: Floppy tissues above vocal cords collapse inward during inspiration. Most common cause of stridor in infants. Usually improves by 12-18 months.
- Gastroesophageal Reflux (GERD): Stomach contents reflux into esophagus. Can trigger laryngeal reflex causing apnea. May cause micro-aspiration.
- Allergies and Infections: Allergic rhinitis causes nasal congestion. Upper respiratory infections cause swelling. Both worsen obstructive apnea.
A mother brings her 4-year-old son to the clinic. She reports he snores very loudly at night, sometimes seemingly pausing his breath before gasping for air. He is also struggling with daytime sleepiness and bedwetting. Given his age, what is the most likely structural cause of his symptoms, and what type of apnea is this?
Answer: He is presenting with classic symptoms of Obstructive Sleep Apnea (OSA). Given his age (4 years old), the most likely structural cause is Adenotonsillar Hypertrophy (enlarged tonsils and adenoids).

- Episodes occur during sleep (especially active/REM sleep).
- May be triggered by: Handling (nursing procedures), Feeding, Temperature changes, Position changes.
- Usually self-resolves with tactile stimulation. May require bag-mask ventilation if severe.
- Hypoxic brain injury: Prolonged low oxygen leads to developmental delay, cerebral palsy.
- Seizures: Hypoxia triggers seizure activity leading to further brain injury.
- Death: Severe, prolonged apnea. Association with SIDS is controversial.
- Failure to thrive: Energy expenditure; poor feeding leading to growth delay.
- Cor pulmonale & Pulmonary hypertension: Chronic hypoxia causes blood vessel constriction placing a massive strain on the right heart, leading to right heart failure.
- Intellectual & Behavioral difficulties: Chronic sleep disruption and hypoxia leads to learning difficulties and ADHD-like symptoms.
- Systemic hypertension & Metabolic syndrome: Sympathetic activation from frequent arousals increases cardiovascular, obesity, and diabetes risks.
When evaluating a child with apnea, consider these conditions:

- EEG (Electroencephalogram): Detects seizure activity.
- Echocardiogram: Rules out congenital heart disease and assesses for pulmonary hypertension.
- Identify and Treat Underlying Cause: This is the most important step! Apnea is a symptom, not a disease.
- Supportive Care: Maintain airway, ensure adequate oxygenation, monitor continuously.
- Prevent Further Episodes: Treat underlying condition, consider medications to stimulate breathing.
| Intervention | Rationale | Nursing Implementation |
|---|---|---|
| Tactile stimulation | Triggers breathing reflex | Gentle rub on soles of feet or chest wall |
| Positioning | Prone position reduces apnea | Place in prone (on tummy) with head turned; monitor closely |
| Temperature control | Cold triggers apnea; overheating also bad | Maintain neutral thermal environment |
| Minimize handling | Handling triggers apnea in preemies | Cluster care activities; gentle touch |
| Avoid vagal stimulation | Vagal response causes bradycardia | No rectal temperatures; no deep suctioning; no NG tube manipulation |
- Methylxanthines (Caffeine Citrate - FIRST LINE):
- Mechanism: Stimulates respiratory center in brainstem; increases sensitivity to CO2; improves diaphragm contractility.
- Dose: Loading dose: 20 mg/kg orally or IV. Maintenance: 5-10 mg/kg once daily.
- Advantages: Wide therapeutic window (safe), once daily dosing, oral bioavailability, fewer side effects than theophylline, improves neurodevelopmental outcomes.
- Side effects: Jitteriness, irritability, tachycardia, gastric reflux, diuresis.
- Theophylline (Alternative):
- Mechanism: Similar to caffeine but less selective.
- Disadvantages: Narrow therapeutic window (toxicity risk), more side effects, multiple daily doses, requires blood level monitoring.
- CPAP: Prevents airway collapse. Mechanical ventilation: For severe episodes, last resort.

| DIAGNOSIS 1: Ineffective Breathing Pattern (Related to: Immature respiratory center OR airway obstruction) | |
|---|---|
| Nursing Intervention | Rationale |
| Place infant on cardiorespiratory monitor with apnea alarm | Detects apnea and bradycardia immediately |
| Apply pulse oximeter | Monitors oxygen saturation continuously |
| Position infant prone (for AOP) or side-lying | Reduces apnea frequency; maintains airway |
| Maintain neutral thermal environment | Cold stress triggers apnea |
| Minimize handling and cluster care activities | Handling triggers apnea in preemies |
| Provide tactile stimulation during apnea episodes | Triggers breathing reflex |
| Have bag-valve-mask and suction ready at bedside | For emergency resuscitation |
| Avoid vagal stimulation (no rectal temps) | Vagal response causes bradycardia |
| DIAGNOSIS 2: Risk for Aspiration (Related to: GERD, impaired swallowing, or altered level of consciousness) | |
|---|---|
| Nursing Intervention | Rationale |
| Position infant with head elevated 30 degrees during/after feeds | Reduces reflux |
| Feed slowly with frequent burping | Reduces stomach distension |
| Consider thickened feeds if GERD present | Reduces reflux episodes |
| Monitor for signs of aspiration (coughing, choking, color change) | Early detection |
| Hold infant upright for 20-30 minutes after feeding | Allows stomach emptying |
| DIAGNOSIS 3: Risk for Injury (Hypoxic Brain Injury) (Related to: Prolonged apnea episodes causing hypoxia) | |
|---|---|
| Nursing Intervention | Rationale |
| Respond immediately to monitor alarms | Delays increase hypoxia duration |
| Stimulate infant at first sign of apnea | May abort episode |
| Provide bag-mask ventilation if no response to stimulation | Ensures oxygenation |
| Document all episodes (time, duration, associated signs, response) | Tracks pattern and severity |
| Ensure caffeine administered on time | Maintains therapeutic level |
- Explain apnea condition, causes, and prognosis in simple terms.
- Demonstrate and teach home monitoring equipment.
- Encourage parents to verbalize fears and concerns.
- Teach CPR and emergency procedures.
- Teach medication administration (caffeine).
- Teach use of home apnea monitor and recognition of emergency signs.
- Teach safe sleep practices (Reduces SIDS risk).
- Schedule and emphasize follow-up appointments.
- When is it needed? Apnea of prematurity not fully resolved at discharge, Infants with ALTE, Certain high-risk conditions.
- Equipment: Cardiorespiratory monitor with event recording, Pulse oximeter.
- Parent Education: How to place leads, respond to alarms, stimulate infant, call for help, CPR, battery backups, keeping a log.
- Duration: Usually until infant is apnea-free for several weeks (typically until 43-44 weeks post-menstrual age for preemies).
- Apnea of Prematurity: Usually resolves by 36-40 weeks corrected gestational age. Generally excellent prognosis if properly managed. Caffeine use is associated with better neurodevelopmental outcomes.
- Obstructive Sleep Apnea: Excellent with appropriate treatment. 80-90% cured after tonsillectomy and adenoidectomy. Untreated OSA leads to significant morbidity.
- Central Apnea from Other Causes: Depends entirely on underlying cause (e.g., Sepsis is good if treated promptly; Brain injury is variable).

Nursing care plan for a pediatric patient with Apnea
Assessment | Nursing Diagnosis | Goals/Expected Outcomes | Interventions | Rationale | Evaluation |
1. Child presents with episodes of apnea lasting more than 20 seconds, cyanosis, and bradycardia (heart rate < 100 bpm). | Ineffective Breathing Pattern related to immature respiratory control as evidenced by episodes of apnea, cyanosis, and bradycardia. | The child will maintain effective breathing patterns with no episodes of apnea, and oxygen saturation will remain above 95%. | – Continuously monitor the child’s respiratory rate, effort, and oxygen saturation using a cardiorespiratory monitor. – Position the child in a supine or side-lying position with the head slightly elevated to facilitate airway patency. – Administer oxygen as prescribed to maintain adequate oxygenation during and after apneic episodes. – Stimulate the child gently (e.g., rub the back or flick the soles) during apneic episodes to prompt breathing. – Prepare for possible resuscitation if apnea persists despite stimulation. | Continuous monitoring helps detect apneic episodes and guide interventions. Proper positioning promotes airway patency and reduces the risk of obstructive apnea. Administering oxygen improves oxygenation during apneic episodes. Gentle stimulation often restarts breathing in infants with apnea. Resuscitation may be necessary in severe cases to restore breathing. | The child maintains a normal breathing pattern, with no further episodes of apnea, and oxygen saturation remains within the target range. |
2. Child exhibits signs of fatigue and decreased responsiveness between apneic episodes. | Activity Intolerance related to recurrent apneic episodes as evidenced by fatigue and decreased responsiveness. | The child will exhibit improved activity tolerance with increased periods of alertness and responsiveness. | – Allow for rest periods between feedings and activities to reduce fatigue. – Monitor the child’s energy levels and responsiveness closely, adjusting activity levels as needed. – Educate parents on the importance of providing a calm, low-stimulation environment to promote rest. – Provide small, frequent feedings to minimize energy expenditure during feeding. | Rest periods help conserve the child’s energy and prevent excessive fatigue. Close monitoring allows for timely adjustments to activity levels based on the child’s energy reserves. A calm environment reduces stress and supports the child’s recovery. Small, frequent feedings reduce the effort required during feeding, conserving energy. | The child demonstrates improved activity tolerance, with increased alertness and responsiveness between rest periods. |
3. Parents express anxiety about the child’s condition and fear of apneic episodes occurring at home. | Anxiety related to fear of apneic episodes and uncertainty about the child’s condition as evidenced by parental verbalization of concern. | The parents will verbalize understanding of the child’s condition and demonstrate confidence in managing apneic episodes at home. | – Provide clear, concise information to the parents about apnea, including causes, signs, and interventions. – Teach parents how to monitor the child’s breathing and how to respond to apneic episodes at home, including the use of home monitoring equipment if prescribed. – Offer emotional support and reassurance, acknowledging the parents’ feelings and concerns. – Encourage parents to ask questions and participate in the child’s care to increase their confidence. | Educating parents helps reduce anxiety by providing them with the knowledge and skills needed to manage the child’s condition. Hands-on teaching and use of monitoring equipment empower parents to respond effectively to apneic episodes. Emotional support reassures parents and validates their concerns. Involving parents in care increases their confidence and sense of control. | The parents verbalize understanding of the child’s condition, demonstrate correct management of apneic episodes, and express increased confidence in caring for their child at home. |
4. Child is at risk for impaired gas exchange due to recurrent apneic episodes. | Risk for Impaired Gas Exchange related to apneic episodes and immature respiratory control. | The child will maintain adequate gas exchange as evidenced by normal oxygen saturation levels and absence of cyanosis. | – Monitor oxygen saturation and signs of respiratory distress continuously, intervening promptly during apneic episodes. – Administer supplemental oxygen as needed to maintain target oxygen saturation levels. – Provide continuous positive airway pressure (CPAP) or mechanical ventilation if prescribed to support the child’s respiratory efforts. – Monitor arterial blood gases (ABGs) or transcutaneous CO2 levels if indicated to assess gas exchange. | Continuous monitoring allows for prompt intervention during episodes of impaired gas exchange. Supplemental oxygen supports adequate oxygenation during apneic episodes. CPAP or mechanical ventilation provides respiratory support in cases of severe or persistent apnea. Monitoring ABGs or CO2 levels provides information on the child’s gas exchange status, guiding treatment. | |
5. Child is at risk for infection due to immature immune system and potential for aspiration during apneic episodes. | Risk for Infection related to immature immune system and potential aspiration. | The child will remain free from infection as evidenced by normal temperature, white blood cell count, and absence of signs of infection. | – Practice strict hand hygiene and aseptic technique during all care and procedures. – Monitor for signs of infection, including fever, increased WBC count, and changes in respiratory status. – Provide prophylactic antibiotics if prescribed, especially in cases of suspected aspiration. – Educate parents on infection prevention measures, including proper feeding techniques to minimize the risk of aspiration. | Strict hand hygiene and aseptic technique reduce the risk of introducing pathogens. Early detection and treatment of infection are crucial to prevent complications. Prophylactic antibiotics may reduce the risk of infection following aspiration events. Parental education ensures adherence to infection prevention practices at home. |
