coryzal Sx (cough, sneeze, fever) precede a dry cough and increased SOB - leads to difficulty feeding -> main reason for admission
recurrent apnoea is serious compx esp in young infants
sharp dry cough, tachypnoea, subcostal/IC recession, hyperinflation of chest, fine end inspiratory crackles, high pitched wheeze- exp>insp, tachycardia, cyanosis/pallor
PCR analysis of NPsecretions
CXR if complicated
pulse oximetry to monitor sats.
ABG/VBG if severe and monitoring for hypercapnia
What could CXR show
CXR if complicated - can show hyperinflation from trapped air due to small airway obstruction, and focal atelectasis (collapse)
humidified O2 by nasal cannulae
monitor for apnoea
assisted vent via CPAP facemask or nasal
full ventilation in some
