why is airway clearance impt?
|
assistance in airway clearing becomes impt when the airway is impaired or ineffective
|
|
As mucus increase in the airways, obstruction occurs leading to
|
air trapping**atelectasis**Ineffcetive gas exchange** Inflammation **Infection
|
|
What are some indicatiosn that a pt needs airway clearnace
|
increased rention of secretion, aspiration, prophylaxis,
prevents ateleclasis, infection, barotrauma, air trapping |
|
list some contradindications and hazards of airway clearance
|
pulmonary hemmorhage, excessive agitation or hypoemia, feeding within 1 hr, history of reflux, untreated pneumo, CHF
|
|
What are the 5 techniques used in airway clear.?
|
Postitive Expiratory Pressure (PEP)
Forced Exhalation Technique (FET) Autogenic Drainage High Freq Chest Compression Flutter Valve Therapy |
|
how are aerosolized drug therapies delivered
|
small volume nebulizer, large volume nebulizer, metered dose inhaler, dry powder inhaler
|
|
With aerosolized drug therapy an effective tx depends on?
|
size and amount of particles produced, characteristics of particles, anatomy of airway, pts' ventilatory pattern
|
|
What type of nebulizer is used in a stsuts asthamticus pt
|
LVN
|
|
What are some advantages of SVN
|
requires little pt corrnidtaion, can be used in acute distress or with reduced inspirtaory flows & volumes, allows modifcation of drug
|
|
Disadvantages of SVN
|
expensive, less easily transported, must clean and prepare, dose in inefficient, delivers a cold wet spray
|
|
Advantages of MDI
|
very portable, provide effiecnt drug delivery, require a very short prep and delivery time
|
|
Disadvantages of MDI
|
diffu. coordination, fixed rug concentation, limited choice of drugs, possible rxn to the propellants used.
|
|
Advantages of DPI
|
limited hand -breath corrdination is needed, no propellants are used, drug doses are easily counted
|
|
Disadvantages of DPI
|
limited # of drugs, possible irrtation of airway from the dry powder
|
|
There are 3 categoried that aerosolized drugs fall into what are they?
|
broncholdilators, Mucolytics, Steroids
|
|
What class of drug would you give a premature infant- decreased breath sounds, decreased chest expansion, presence of wheezes & retractions , increased RR, nasal flaring and grunting
|
Bronchodilator
|
|
what class of aerolozed therapy do you give a pt with presence of thick secretions that are difficult for the pt to expel
|
Mucolytics
|
|
What type of aerosolized therapy do you give a pt that had infalmmatory process that is present- BPD or asthma
|
Steroids
|
|
What are some hazards assocaited with SVN Therapy
|
Nosocomial INfection, medictaion side effects, drug reconcentartion, ventilator malfunction, excessive noise
|
|
What are some indications for SX
|
need to remove secretions, after CPT, ETT tube q 4-6
** Sx must be done 20 min prior ro ABG**** |
|
What type of equip,. is needed to SX
|
cardiac, oxygen sat, sethoscope, resuscitation bag and mask with O2 source, Sterile saline for lavage, suction catheter kit, water soluble jelly
|
|
In neonates the Sx regulator should be set at
pediatric pts |
-50 to -80 mmhg
-80 to 100 mmhg |
|
WHen Sx a neonate how long should it take
|
10 seconds
5 second suctioing |
|
What are some hazards of Sx
|
bradycardia, hypoxemia, musocsal damge, atelectasis, airway contamnation, accidental extubation
|
|
skin will not appear cynatoic until ________ gm of Hgb becomes destaurtaed
|
5 gm
|
|
What are some hazards of O2 therapy
|
retinopathy of prematurity, O2 toxcity leading to BPD, Cerebral Vasocnstriion, Fire Hazard
|
|
The FiO2 blender can acheive concentarions of what
|
21-100%
|
|
When using an oxygen alalyzer its hould be calibrated to what and how oftern should they be done?
|
calibrated to RA and to 100 %
Calibrations should be done at least every 8 hours |
|
What are the characteristics of a low flow humidifer?
|
designed for flows 10 L/min or less, supplies a relatively small amt of humdity, does not heat the gas, allows the gas to bubble up through a reservoir of sterile H2O
|
|
What are some Characteristics of a high flow Humidifer
|
flows > 10 L/min
Provides a fully saturated gas at a desired temp **passover humidifer** |
|
What is an O xygen hood and what FIO2 % does it provide
|
clear hard plastic hood that fits over the infants head, provides O2 enriched environment for pt provide FIO2 less than 50%
|
|
what is the typicla flow used on a neonate via nasal cannula
|
< 1 L/min
|
|
What is the purpose of an Oxygen Tent
|
Provide an O2 enriched, cool mist to the pt environment for the Tx of croup & other airway swellings
|
|
When is an O2 tent most commonly used
|
for croup
|
|
What is the purpose of a incubatory
|
provide a temp controlled, quiet environment, allows direct flow of O2, [ ] of O2 depneds on liter flow of O2 into the venturi
|
|
What is the main problem with the Incubator
|
constant opening of doors and portholes- makes for diffculty to maintains [ ]'s
|
|
What are the 2 type of Resusciation bags
|
self inflating
flow rating |
|
what is a flow rating bag
|
Rt provides the % of O2 that is used to power them, FiO2's of 100 % can be achieved by using pure O2 to inflate the bag
