Lecture 03 Respiratory Illnesses Flashcards
Why are newborns able to retract their thoracic cage during labored breathing?
It’s due to their round and soft thoracic cage.
Why are infant’s trachea and bronchi more likely to collapse?
Due to less tissue and cartilage
Why are infants more likely to experience respiratory distress from mucous and edema?
Due to their smaller airways.
Why are peds more likely to have rapid and widespread transmission of organisms?
They ahve shorter airway structures.
sidenote: kids have less smooth muscle
When are infants obligatory nose breathers?
Less than 4~6 months old.
Their passages are smaller from 4 weeks to 6 months.
What is breathing like in kids less than 6/7 years old?
Breathing is less rhythmic and diaphragmatic or abominal.
Periodic breathing in infants.
Assessment: have to check RR for a full minute
Respiratory rate is higher (increased metabolism) and responds dramatically to emotion, illness, fever and exercise.
What are peds characteristics that affects the respiratory system? (5)
- Respiratory tract has narrow lumen until 7~8 years old
- Fewer alveoli until age 12
- Respiraotry muscles are weaker, there is smaller vital capacity, thus less reserve
- Immune system is immature (less lymphoid tissue)
- Young children may have more severe symptoms
What occurs to older children that are repeatedly exposed to viral illnesses?
It’ll increase their immunity.
What are some S/S of an infant in respiratory distress?
- Grunting sounds, nasal flaring, head bobbing
- Different areas of infant’s body will be seen retracting: intercostal, subcostal, substernal, calvicular, suprasternal
What would you do in Respiratory Func Assessment?
- Ability to maintain airway
- Breathing, the rate and mechanics of it
- Skin color and temperature
- Pulse Oximetry
- Cap refill, circulation
What are some symptoms of respiratory dysfunction? (9)
- }Air hunger/restlessness
- }Increased RR, effort, diminished breath sounds, apnea
- }Nasal flaring, open mouth breathing
- }Retractions (use accessory muscles)
- }Grunting/stridor
- }Decreased LOC or unresponsiveness to parents or pain
- }Poor skeletal tone
- }Cyanosis (circumoral)
- }Decreased Oximetry (check O2 delivery system)
Assessment of Worsening Condition. What is the first thing you should think about?
Know the baseline, is the child getting worse or better?
Look at respiratory pattern
}RR 70 to 80 for 2 days and is now 60
}Child wheezing last few days and now with decreased/absent wheeze
}Changes in oximetry (feeding, activity, rest)
}Apnea
What are the some nursing diagnoses for ABC priorities?
- }Ineffective airway clearance
◦Saline drops/bulb suctioning - }Ineffective breathing patterns
- }Impaired gas exchange
- }Anxiety/fear
- }Inability to sustain spontaneous ventilation
- }High risk infection
- }Impaired communication
What are 5 URI? Upper Respiratory Tract Illness?
- Nasopharyngitis (common cold)
- Pharyngitis
- Tonsillitis
- Influenza
- Otitis Media (OM)
Why do children have fewer respiratory infections as they grow older? (3)
}Increased immunity to virus from previous exposure
}Increased amount of lymphoid tissue as they grow
}Increased ability to resist viral illnesses
What are 4 teaching points of managing nasopharyngitis?
}Home management with antipyretics, bulb suctioning as indicated, Normal Saline (NS) nasal drops, maintaining adequate fluid intake & comfort measures
}Teach parents signs of respiratory complications and when to seek medical attention
}Recurrent URI’s very common in children less than three years. As exposure & immunity increases, frequency drops.
}Ear infections commonly occur with/after a URI and signs of infection should be reported to provider.
How useful could cool mist be? What is a risk of it?
}Cool mist safer (decreased risk burns) with no evidence of advantage to steam
}Both promote a more comfortable environment; loosen secretions
}They DO NOT decrease viscosity of secretions
}Risk for growth of organisms exists in both (less with cool water)
}NS Nebs (may loosen secretions, so it’s easier to suck out secretions, and open the airway)
What should you look for in Feeding Patterns during an Assessment of Worsening Condition?
Feeding Patterns
- }Increased feeding time or disinterest
- }Decreased sats with feeding
- }Increased respiratory effort
- }Gagging difficulty swallowing when eating
- }Apnea
- }Is it safe to eat or drink?
- }LOC (alertness, activity, response to stimuli & parents)
