nasal cannula and any mask w/ small bore tubing is always on a
bubble humidifier
proper function of humidifier should be checked by occluding or pinching the connecting tubing and you must hear for the
whistling sound
if there is no whistling sound, check for leaks
cracked or loose
worn/missing gasket
broken/loose connections
6 types of humidifiers
bubble
memnrane cartlidge systems- vapotherm
passover
HME
wick
heated wire circuit
membrane catridge sys has a humidification sys that can heat and humidify oxygen at flow rates up to
40 l/min
passover commonly used in conjunction with
infant vent and circuits
the HME should be located in the vent circuit btwn
wye and the pt (where deadspace is located)
when should you replace HME
when airway pressure increases
HME idea use is for pt
transport
short term vent
which humidifier can deliver 100% body humidity
wick humidifier
which humidifier has a low risk of cross-contamination
wick
what is used in conjunction with vent humidi sts to minimize circuit condensation
heated wire circuits
an aerosol is created and then encounters a baffle. larger particles are filtered out and return to the reservoir thus producing a SMALLER more uniform particle size
nebulizer
SVN are used to nenulize
small doses of meds
a sputtering sound indicates that all of the solution has been
nebulized
LVN are utilized to deliver bland aerosols to the upper airway to
decrease the chance of edema
or humidity deficit
if pt has LVN and thick secretions are developing, you can add a
heating element
if the LVN is not misting enough
clogged capillary tube
insufficient flow
water collecting in the tubing will casuse less air to be entrained causing the Fio2 to
increase
aerosol produced in short puffs indicates
condensation in the tubing
increased rate and depth of breathing may indicate
insufficient flow
nebs have a higher rick of contamination because
particles are produced
when using a bleder w/ a large vol neb make sure to set
set bleder at desired fio2
set the air entrainment port on LVN at 100% (closed)
SPAG is specifically designed to deliver
Ribavirin (virazole)
Ribavirin (Virazole) is to treat
Resp Syncytial Virus
a nebulizer that has a electrical energy through the use of a transducer with a piezoelectric quality
ultrasonic nebulizer
ultrasonic has the highest output range of
aqueous solution without heating
to create cough using a ultrasonic neb just add
saline
to increase mist on a ultrasonic neb, you must
increase amplitude (volume)
what should you do before giving a new MDI to pt
prime the med atleast 4 times
spacers and holding chambers can be used to overcome
