advanced paediatric life support Flashcards
recession
more readily develops in younger children due to more compliant chest wall
presence in children over 6-7 indicates severe respiratory failure
the child who has become exhausted - recession decreases as they develop respiratory failure
stridor
more pronounced on inspiration
sign of laryngeal or tracheal obstruction
wheeze
indicates lower airway narrowing
more pronounced on expiration
grunting
expiration agains a partially closed glottis
sign of severe respiratory distress
characteristically seen in infants with pneumonia or pulmonary oedema
children presenting with respiratory failure without increased work of breathing
- exhaustion will reduce increased effort of breathing
- cerebral depression from raised ICP, poisonging or encephalopathy will decreaase respiratory drive
- children with neuromuscular disease
rales
bubbling, clicking or rattling sounds in the lungs
incoming air opens up closed air spaces in the lungs
ronchi
harsh, rattling sounds that resemble snoring
occur as a result of blockage or inflaammation of the small airways
pulse oximetry
used to measure arterial oxygen saturation
in severe shock or hypothermia, there may be poor pulse detection
should be 97-100%
heart rate
hypoxia produces tachycardia in the older infant and child
anxiety and fever will also cause tachycardia
severe or prolonged hypoxia leads to bradycardia, this is a pre-terminal sign
skin colour
hypoxia produces vasoconstriction and skin pallor
cyanosis is a late and pre-terminal sign
mental status
hypoxic or hypercapnic child will be agitated or drowsy
pulse volume
blood pressure is maintained until shock is severe
absent peripheraal pulses or weak centraal pulses are serious signs of advanced shock
Cap refill
should occur within 2 seconds
slow refill time may indicate early septic shock
blood pressure
hypotension is a late and pre terminal sign of circulatory failure - cardiac arrest is imminent
hypertension may be the cuase or result of come or raied ICP
urinary output
urine output of less than 1 ml.kg.hr for children or less than 2 ml/kg/hr in infants indicates inadequate renal perfusion during shock
history of reduced wet nappies or urine production sshould be sought
