Question | Answer |
---|---|
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 |
Te | TCT-Ti |
%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 | 1.it 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 2.tube too small |
sever hypoxemia | 39 and less |
moderate hypoxemia | 40-59 |
mild hypoxemia | 60-79 |
Vi | (Vt/Ti) x 60 |
