Oxygen Therapy and Oxygen Delivery (Pediatric) - CE

ALERT

Fire is a significant hazard where oxygen is used. Do not permit flames, sparks, or smoking.

OVERVIEW

The administration of oxygen to children requires the selection of an oxygen delivery system that suits the child's age, size, needs, clinical condition, and therapeutic goals. Oxygen delivery systems are categorized as low-flow (variable performance) systems or high-flow (fixed performance) systems. With low-flow systems, 100% oxygen mixes with room air during inspiration, and room air is entrained, making the percentage of delivered oxygen variable. High-flow devices provide such a high flow of premixed gas that the child is not required to inhale room air. Supplemental oxygen therapy is often recommended for children when peripheral oxygen saturation is consistently below 94%.1

A nasal cannula, oxygen mask (e.g., simple face mask, partial rebreathing mask with reservoir, a nonrebreathing mask with reservoir, Venturi mask), face tent, and oxygen hood deliver supplemental oxygen to children to treat hypoxia, respiratory distress, and respiratory failure (Table 1)Table 1 (Table 2)Table 2 (Table 3)Table 3. Because oxygen can dry the respiratory system, many oxygen delivery systems allow for humidification.

  • A nasal cannula is a low-flow oxygen device (Table 1)Table 1. For infants and toddlers who may poorly tolerate a mask, nasal prongs may be a good alternative. The nasal cannula allows breathing through the mouth or nose. The child inspires room air in addition to the supplemental oxygen, and a variable concentration of oxygen is delivered.2 A nasal cannula can deliver 22% to 60% oxygen with appropriate oxygen flow rates of 0.5 to 2 L/minute.2
  • A simple face mask is a low-flow oxygen device (Table 2)Table 2. A simple face mask can deliver 35% to 60% oxygen with an appropriate flow rate of 6 to 10 L/minute. A minimum of 6 L/minute of oxygen flow is needed to prevent rebreathing of exhaled carbon dioxide.2
  • A partial rebreathing mask with a reservoir bag is a face mask that delivers moderate to high concentrations of oxygen. Frequent inspection of the reservoir bag is required to ensure that it remains inflated; if it is deflated, exhaled air collects in it, which results in the child rebreathing large amounts of exhaled carbon dioxide. Side port openings on the mask vent exhaled air on expiration and allow room air to enter on inspiration. The delivered oxygen percentage varies, depending on the rate and depth of the child's breathing.
  • A nonrebreathing mask with reservoir is a high-flow oxygen delivery device used for children requiring a higher concentration of oxygen (Table 2)Table 2. A nonrebreathing mask can deliver a concentration of up to 95% oxygen with an oxygen flow rate of 10 to 15 L/minute.2
  • A Venturi mask is a cone-shaped device with entrainment ports of various sizes at its base. The entrainment ports adjust to deliver various oxygen concentrations. The mask is useful because it delivers a more precise concentration of oxygen to the child.
  • A face tent is a shieldlike device that fits under the child's chin and encircles his or her face. It is used primarily for humidification and for oxygen only when the child cannot or will not tolerate a tight-fitting mask. Because the tent is so close to the child's face, the amount of oxygen delivered to the child cannot be estimated.
  • Oxygen tents and hoods can provide high concentrations of humidified oxygen, which is useful in a child with airway inflammation, epiglottitis (croup), or other respiratory tract infections.

CHILD AND FAMILY EDUCATION

  • Provide individualized, developmentally appropriate education to the family and child based on the desire for knowledge, readiness to learn, and overall neurologic and psychosocial state.
  • Explain the oxygen delivery device, including the rationale for its use and the risks.
  • Explain the expected duration and outcome of supplemental oxygen delivery.
  • Explain hypoxemia and the signs and symptoms of respiratory distress.
  • Explain the necessary assessments during supplemental oxygen delivery.
  • Discuss safety precautions for oxygen use.
  • Encourage questions and answer them as they arise.

ASSESSMENT AND PREPARATION

Child and Family Assessment

  1. Perform hand hygiene before patient contact.
  2. Introduce yourself to the child and family.
  3. Verify the correct child using two identifiers.
  4. Assess the child's developmental level and ability to interact.
  5. Assess the child for signs and symptoms of inadequate oxygenation and ventilation.
    1. Increased work of breathing (e.g., tachypnea, nasal flaring, grunting, intercostal retractions, subcostal retractions)
    2. Decreased oxygen saturation levels
    3. Cyanosis
    4. Anxiety
    5. Altered level of consciousness
  6. Determine if a condition in the medical history predisposes the child to baseline lower-than-normal oxygen saturation levels (e.g., cyanotic heart disease).
  7. Assess the child's and family's understanding of the reasons for and the risks and benefits of the procedure.

Preparation

  1. Select the appropriate oxygen delivery device per the practitioner's order (Table 1)Table 1 (Table 2)Table 2 (Table 3)Table 3.

PROCEDURE

  1. Perform hand hygiene and don gloves and, if the child's health status requires, a gown, mask, and eye protection or face shield.
  2. Verify the correct child using two identifiers.
  3. Explain the procedure to the child and family and ensure that they agree to treatment.
  4. Place the selected oxygen device on the infant or child. If one method of oxygen delivery upsets the child, consider changing to another method.
  5. Adjust the flowmeter to deliver the desired amount of oxygen. Ensure that the liter flow is appropriate for the device.
  6. Apply and secure the noninvasive oxygen delivery device, ensuring that it is the correct size.
    Rationale: The correct size device ensures optimal delivery of the prescribed amount of oxygen and reduces the risk of skin breakdown.
    1. If using a mask, ensure that it covers the mouth and nose but not the eyes.
    2. Use adhesives to secure a nasal cannula or an elastic strap for a face mask.
  7. Evaluate the child's oxygen delivery device for proper fit.
    1. Ensure that nasal cannula prongs remain in the nares.
    2. Ensure that the infant's head remains in the oxygen hood.
  8. Discard supplies, remove personal protective equipment (PPE), and perform hand hygiene.
  9. Document the procedure in the child's record.

MONITORING AND CARE

  1. Monitor cardiopulmonary status, including vital signs, oxygen saturation, and indicators of oxygenation and ventilation.
    Reportable conditions: Tachypnea, bradypnea, apnea, increased work of breathing, nasal flaring, retractions, diminished or abnormal breath sounds, agitation, anxiety, altered mental status, changes in oxygen saturation, changes in blood gas values, arrhythmias (including tachycardia and bradycardia), hypertension, hypotension, changes in skin color such as pallor or cyanosis, changes in peripheral perfusion
  2. Monitor the child's respiratory status and need for increased or decreased oxygen therapy.
    Rationale: Changes in oxygen delivery to avoid oxygen-related complications are based on the child's condition.
  3. Monitor the child for signs of hypercarbia.
    Rationale: If gas flow is too low, hypercarbia may develop.
    Reportable conditions: Increasing agitation, rapid and deep respiration, dyspnea, progressive lethargy
  4. Monitor a child in an oxygen hood carefully.
    Rationale: Suffocation may occur if the child puts his or her mouth or nose against the plastic walls.
  5. Assess the skin frequently for breakdown.
    Rationale: The bridge of the nose and the cheeks are prone to skin breakdown.
    Reportable condition: Skin breakdown associated with the device
  6. Monitor the child for signs of dry mucous membranes.
    Rationale: Dry and sore mucous membranes can develop with the delivery of oxygen.
    Reportable conditions: Dry or cracked mucous membranes
  7. Provide humidification when the supplemental oxygen delivery device permits. If humidified oxygen is used, check the linens frequently and change them as needed.
    Rationale: Oxygen can dry the respiratory system, resulting in thick secretions that are more difficult to mobilize. Dry air can lead to breakdown of the nasal mucosa, resulting in nosebleeds.
  8. Assess, treat, and reassess pain.
    Rationale: Pain in children can decrease the ability to breathe deeply, thereby affecting gas exchange.
