What is the narrowest part of the airway
Cricoid cartilage
3 components of work of breathing
- Compliance work
- Resistance work
- Airway resistance
List some examples from an assessment of respiratory distress
- ↑ RR
- ↑ HR
- ↓ saturation
- retractions or nasal flaring
- grunting
- sweating, clammy skin
- auscultate breath sounds— stridor, wheeze, etc
- head bobbing
- croupy cough
- cyanosis
- conscious lvl: drowsy and hypercapnia
- position: tripod position
What are the normal ranges of neonates? (HR, RR and systolic BP)
HR: 120-180bpm
RR: 40-60 min
Systolic BP: 60-80mmHg
Ethiology of:
- Tachypnea
- Hyperpnea
- Dyspnea
- Orthopnea
- Tachypnea— pulmonary disease, metabolic acidosis
- Hyperpnea– diabetic ketoacidosis
- Dyspnea– (acute distress)
- - pneumothorax intermittent distress, asthma chronic lung problem - Orthopnea – asthma, pulmonary edema
Goal of oxygen therapy
- Relieve hypoxemia
- ↓ work of breathing
- ↓ myocardial stress
Average range of vacuum settings for infants and children.
Infant: 75-100mmHg
Children: 100-120mmHg
(Ref: adult is 120-150mmHg)
Symptoms of Laryngomalacia
Stridor and difficulty in breathing
List 3 lower respiratory tract infections.
- Acute laryngotracheobronchitis (Croup)
- Bronchiolitis/ Bronchitis
- Pneumonia
Presentation of Acute laryngotracheobronchitis (Croup)
- fever
- breathing problem at night
- a few days of URTI followed by onset of stridor and harsh barking cough (usually worsen w crying or agitation)
Treatment of Acute laryngotracheobronchitis (Croup)
- Humidified O2; inhaled epinephrine
- Corticosteroids: PO/IV dexamethasone
(if becomes severe, also administer adrenaline & monitor for few hours)
Presentation of bronchiolitis
- starts with URTI, symptoms worsen 3-5 days
- peak 5-7 days; resolve by 2-3 weeks
Treatment of bronchiolitis
- oxygenation aim SaO2 > 95%
- hydration & nutrition (KIV NGT)
- relieve nasal congestion
- bronchodilator if indicated
Causes of pneumonia (5)
- Streptococcus pneumonia (most common)
- Mycoplasma pneumonia (most common in kids)
- Bacterial pneumonia
- Viral pneumonia
- Aspiration pneumonia
Management of pneumonia
- oxygenation aim SaO2 > 95%
- hydration & nutrition (KIV NGT)
- oral antibiotics (1-3months old can start)
- IV antibiotic eg. Ampicillin and Gentamycin for neonates
Causes of bronchial asthma
- bronchospasms
- ↑ mucus secretions
- mucosal oedema
Bronchial asthma’s characteristics
- airway inflammation
- intermittent airflow obstruction
- bronchial hyperresponsiveness
Describe severe persistent asthma
- continual day time symptoms
- frequent night time symptoms
- lung function testing <60% of predicted value
If score is >20 for Asthma Control Test Score (ACT Paed), asthma is well-controlled. T/F?
True
The strongest predictor for wheezing that develops into asthma is atopy. T/F?
True
Management of :
- Acute asthma
- Mild asthma
- Moderate asthma
- (Acute) Pharmacotherapy
- relievers: salbutamol/ipratropium bromide
- preventers: corticosteroids
- O2 - (Mild) Salbutamol MDI/ Nebuliser
- (Moderate)
- O2 to maintain SaO2>95% via nasal prong
- Salbutamol MDI/ Nebuliser
- Oral prednisolone (corticosteroid hormone)
What BP is hypotension in neonate & infant (1-12 months)?
Neonate: 60-80mmHg
Infant (1-12 months): 70-90 mm Hg
Early and late signs of cardiovascular collapse
EARLY:
- tachycardia
- altered perfusion
- skin: prolonged capillary refill
- brain: altered level of consciousness
- kidneys: ↓ urine output
- pulse: weak or thready
LATE:
- skin: cold & clammy; poor capillary refills
- hypotension
- bradypnea (slow breathing rate)
- acidosis
- flaccid tone
- ↓ response to pain
Normal urine output
1-2ml/kg/hr
