2 requirements for asthma diagnosis
- FEV1/FVC 12% with dilators (in adults must be over 200ml)
how to diagnose in preschoolers
- not able to do PFTs
- need careful Hx and PHx
what is in asthma predictive index
>4 wheezing episodes in past year PLUS ONE major crit.: - parent with astma - atopic dermatitis - allergen sens OR 2 minor crti.: -food sens - peripheral eosinophilia - wheezing not related to infection
what is goal of asthma Sx management
want them to be asymtomatic
what are two main therapeutic targets
- smooth muscle dysfunction
2. airway inflammation
2 main types of meds and their types
- controllers
- roids
- LTRA
- amalizumab - relievers
- SABA
- LABA
what are guidelines for controller therapy
- regular controller therapy indicated for those with poor asthma control
- ICS are first line for all ages
- second line is LTRA
if taking low dose ICA, what are three options to increase
- increase to mod or high dose
- add LABA
- add LTRA
- not enough evidecne for
what is reccomendation for adults with low dose ICS for escalation
add a LABA
what is reccomendations for children on low dose ICS
mod or high dose
what is recc for children on mod-high dose ICS
add a LABA
what is CF
- auto recc. disorder
- affects lung, panc, intestines, liver
- affects CF transmembrae regulator
what is CFTR needed for
allows Cl out to keep a good layer of airway surface fluid
