check the airway for any obstructions
central cyanosis is a sign of late stage airway obstructionin most cases simple methods of airway clearance are required and can be used = airway opening manoeuvres, airways suction, insertion of an oropharyngeal or nasopharyngeal airway. Tracheal intubation may be required when these fail.
oropharyngeal airways are golden standard however if a patient is at risk of seziures nasopharyngeal airway input can be used as a sezior may cause locked jaw to occur
nasopharangeal airways may have a safety pin inserted into its distil end of the tube to ensure the tube does not FULLY insert into the nose
give oxygen at a flow of (usually 15 L min-1) in acute respiratory failure aim to have a target saturation of 94-98%. in patients who are at risk of hypercapnic respiratory failure recieve oxygen at saturation of 88-92% as their bodys function at this saturation
general overview is important
take a respiratory rate the normal is generally between 12-20 breaths a minute
