Respiratory Flashcards
Purpose of the Respiratory System
Provides O2 to the cells
Ventilation
Removal of O2
Respiratory Dysfunction Causes
Infection
Trauma- pneumothorax
Oncology- tumor
Upper Airway Anatomy
Tongue is a lot larger- sleep apnea- obstruction
Throat is smaller
Pharynx- a lot narrower
Cartilage in Upper Airway
Funnel shaped airway- 12 yrs old straightens out
Relevant for nurses who preform intubation
Development of Lower Airway
Increases A LOT up into adolescence
With a vent- weight is based on norms when thinking of volume
Bagging- small children = small bag, risk of pneumothorax if too much air!
Increase in diameter of lower airway
Increase in alevoli in 8-10 year olds
Musculoskeletal Development
Increase rigidity in the rib cage- uses energy to open the muscles
Babies are belly breathers!
Respiratory Assessment
Rate, Rhythm, Depth, Quality
Can assess most visually
Tachypnea
Increased rate
Bradypnea
Decreased rate
Dyspnea
Distress during breathing
Apnea
Cessation of breathing
Hypoventilation
Decreased depth (shallow) and irregular rate
Hyperventilation
Increased rate and depth
Kussmal Respiration
Hyperventilation, gasping and labored respiration
Diabetic coma
Respiratory Acidosis
Cheyne- Stokes Respiration
Gradually increasing rate and depth with periods of apnea
Seesaw Respiration
Chest falls on inspirations and rises on experiation
Upper airway occlusion
Croup, foreign body
Initial Signs of Respiratory Distress
Restlessness Tachypnea Nasal flaring Retractions Color Changes Head bobbing Grunting, striddor, wheezing
Decompensataion Signs
Anxiety Irritability Decreased level of consciousness Confusion Hyper/hypotensioin Suddenly decompensates because the child can compensate for a long time!
Imminent Respiratory Arrest
Bradypnea Bradycardia Cyanosis Stupor Coma Then quickly into cardiac arrest
Respiratory Failure
A laboratory diagnosis PO2 < 60 (normal 80-100) PCO2 > 50 (normal 35-45) NEED ABGs to say failure Interventions: supplemental O2, determine increasing level of O2 by checking pulse ox, positioning, suctioning, cough and deep breathing, percussion and vibration
Respiratory Distress Management
EARLY RECOGNITION IS KEY Watch for increase in heart rate and RR NO change in BP NPO- risk of aspiration Position, O2, clear secretions, equipment at bedside, Rapid response team, PICU transfer
Respiratory Acidosis
Increase CO2
Hypo-ventilation- airway obstruction, neuro-trauma
<7.35 pH
Confusion, lethargy, headache, increase ICP, Coma
Respiratory Alkalosis
Decrease CO2
Hyperventilation- hypoxia, anxiety, fever
>7.45 pH
Confusion, dizziness, neuromuscular irritability, muscle cramping and spasms
Acute Life Threatening Event
ALTE
Under 2 months
During feeding, sleep, wide awake
Emergency resuscitation
Does not mean it will turn into SUIDS
Several times a month will see the symptoms
Causation: significant reflex, seizure, infection, acute sepsis
