Gas Exchange NUR 211 Practice
Questions and Correct Answers
Artificial Airways ✅Ambu bag
ETT
Trach

Normal ABG values ✅pH: 7.35-7.45
PCO2: 35-45mm Hg
PO2: 80 to 100 mm Hg
HCO3: 22-26 mEq/L

Vent setting compared to ABG ✅Increased vent= decreased CO2
Decreased vent= increased CO2

endotracheal tube (ETT) ✅Cuff-> forms seal in trachea to O2 in lungs
Pilot balloon-> checks cuff pressure ( be careful when squeezing
-Increased pressure= tissue necrosis
-Decreased pressure= bad seal on trachea
Pressure manometer to check-->pilot balloon should have volume
-Pay attention to numbers on side when placed

Intubation ✅laryngoscope-> landmark vocal cords
RN-> checks teeth before and after--> assessment
RN post intubation checks
-Check lung sounds
-Bilateral rise and fall of chest
-CO2 checker (Gold good)
If tube in stomach= V, aspiration
Chest x- ray for check--> 3-5cm above carina -> can go into one lung or not low
enough--> air in stomach

RN during intubation ✅Focus on giving pt. O2 during procedure during long periods of
no Oxygen (intubating MD can be hyperfocused)
If pt. not relaxed then--> paralytic and sedition--> needs relaxing--> can cause damage
or bleeding

RN responsibilities intubation ✅RN post intubation checks
-Check lung sounds
-Bilateral rise and fall of chest
-CO2 checker (Gold good)
RN assessment and wait for x-ray after
Measure at specific landmarks--> RN assess

, tracheostomy tube ✅indwelling tube inserted directly into the trachea to assist with
ventilation
-Obturator used when trach comes out--> put in the trach and put back in.

mechanical ventilation indications ✅1) Apnea or impending inability to breathe
2) Acute respiratory failure
pH <7.25 (or heading that way)
pCO2 >50 (or heading that way_
3) Severe hypoxia
pO2 <50
4) Respiratory muscle fatigue: RR <12

mechanical ventilation ✅Pushing volume of air into lungs
Different amounts of air needed
Add O2 and RR

Control Mandatory Ventilation (CMV) ✅Machine is in charge of pt. gas exchange fully
Ex-
RR: 12
TV: 400mL
FiO2: 50%

assist control ventilation ✅rate is variable but tidal vol is preset so each breath is
delivered at a set vol regardless of pts needs
-Pt can breath over vent if needed
Example:
Pt RR:14
RR:12

Assist Control Vent info ✅ABG checked each time when setting is changed
IF PT is breathing a lot over the vent setting= Alkalosis
1st-->Pt needs to be oriented or be given meds to relax--> ABG checked to be sure
RN CANT extubate or changed vent setting

Synchonized intermitten mandatory ventilation (SIMV) ✅Pt RR is lowered to allow for
pt. to work respiratory system
Pt breathes in the FiO2 on there own
-If pt. goes into respiratory distress go assess and then call doctor--> suggest to go
back to AC (check ABG)
-SIMV pt can ambulate with order--> needs to people watching vent and then watching
pt.

extubation equipment ✅Large syringe, scissors
Oxygen delivery device
