RTH 131

what does a dead space over 60% indicate pulmonary ebolism
why does VD/VT over 60% mean PE because the air is ventilating but there is no blood to perfuse
shunting can mean what atelectasis
why is shunting atelectasis blood if there to perfuse but there is no air ventilating
V/Q mis match can mean what pneumonia
why does V/Q mis match mean ppneumonia some ventilation with perfusion, you can give oxygen to improve
if you give O2 to a pt and they dont respond what is that called refractory hypoxemia
what is refratory hypoxemia a sign of shunt
what do you increase first PEEP of FiO2 FIO2 to 60% then increase PEEP
peak flow formula Ve x (I+E)
TCT formula 60/f
Ti formula TCT/ (I+E)
Vt formula (Vi/60) x Ti
Ve formul Vt x f
%Ti 100/ (I+E)
LMA cuff pressure 60cmH2O
pressure maintained during PEP 5-20cmH2O
pressure set for PEP 10-20 cmH2O
what I:E ratio is created with PEP 1:3 1:4
PEP no longer than 20 min
If MIP is low what does that indicate low muscle strength from a neromuscular disease
Ti effected by what 4 things 1.RR 2.Vt 3.Vi 4..PIP
what can you use to help refractory hypoxemia CPAP- need the PEEP/pressure to push in O2
2 things to remember about the catheter before suctioning is the right size 2.pressure if right
if you cant remove secretions what 2 things can you put into artificial airway to break up secretions 1.saline 2.mucomyst
if bicarb is high in resp acidosis what does that mean renally compensated
3 things caused by not hyperoxygenating before sxuctioning 1.tachycardia 2.hypoxemia 3. bradycardia if dying
which reflex is affected by suctioning carinal
if pt is on PEEP and you are extubating what should you put them on after tube is out CPAP with same PEEP
3 things a pharyngeal airway does 1.patient airway 2.suctioning (pharyngeal with oral and tracheal with nasal) 3.maintain upper airway
Cst formula VTe/(Plat-PEEP)
if patient is on control mode and the flow is off what is effected the I:E ratio
2 reasons peak flow alarm goes off 1.pressure 2.VT
what is tracheal stenosis narrowing of trachea
what causes tracheal stenosis cuff pressure too high
noram al cuff pressure 20-25mmHG 25-35cmH2O
if pat has a head trauma what should we do intubate using jaw thrust, no PEEP or pressure cause we don't know how bad they are injured yet but need a patient airway
Vi formula VE x (I+E)
what does PEEP increase the FRC
if a pt is in pain what is the medicine given morphine
if given to much pain meds what can happen to pt stop breathing
epiglottic edema can cause stridor what med ca be used racemic epi
if pt OD what med is given narcan
alveolar ventilation increases what Vt
Ve increases from what 2 things 1.Vt 2.f formula (Vt x f)
if COPD pt needs O2 where should we bring it to their baseline which is probably lower than a normal person
2 things causing a cuff leak 1.damaged cuff too small
sever hypoxemia 39 and less
moderate hypoxemia 40-59
mild hypoxemia 60-79
Vi (Vt/Ti) x 60
