RTH 131
| 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 |
