measure flow at the airway opening? - ANSWER: Pneumotachometer
Calculate the Expiratory Time (TE). RR = 20, TI = 1.2 sec - ANSWER: 60sec / 20 bpm =
3 sec, Total Cycle Time
3 sec - 1.2 sec = 1.8 sec
Calculate the I:E Ratio. TI = 1.2 sec, TE = 1.8 sec - ANSWER: 1..2 : 1..2 = 1:1.5

the Control Variable? - ANSWER: Volume
Describe this Breath Sequence: A preset VT and Flowrate are present during assisted
and controlled breaths. - ANSWER: CMV (Assist/Control)
The sign that starts inspiration is called the __________________. - ANSWER: Trigger
, The _____________________ (PEEP) indicates what happens during the expiratory
phase of the breath cycle. - ANSWER: Baseline Variable
To be classified as a spontaneous breath, the patient must do what two things? -
ANSWER: Trigger AND Cycle
Which breath sequence has a set frequency of mandatory breaths per minutes and
spontaneous breaths are not possible? - ANSWER: CMV (Assist/Control)
In which type of target scheme does the ventilator switch between PC and VC? -
ANSWER: Dual
What is the CPP is the BP = 75/50 and the ICP = 35? - ANSWER: (75 + (2x 50) / 3) - 35
= 23
We want the CPP to be > ______mmHg. - ANSWER: 40
What mode provides synchronized breaths with a set VT but allows a patient to take
spontaneous breaths in between? - ANSWER: VC-SIMV
The use of Noninvasive CPAP _______________ FRC. - ANSWER: Increases
Make the correct settings adjustment: NIV Mode = S/T, IPAP = 9, EPAP =4, FiO2 =
60%, pH = 7.35, PaCO2 = 55, HCO = 35, PaO2 = 51 - ANSWER: IPAP 12, EPAP 7 to
maintain the same pressure support (5cmH2O) to the patient
Calculate the PA-a(DO2). FiO2 = 70%, pH = 7.19, PaCO2 = 81, HCO3 = 18, PaO2 = 59 -
ANSWER: ((760 - 47) x 0.7 - 81) - 59 = 359 mmHg
What is the normal value for f/VT (RSBI)? - ANSWER: <100
What is the normal value for VC? - ANSWER: >10 mL/kg
What is the normal value for MEP? - ANSWER: <-20
What is the normal VD/VT Ratio? - ANSWER: <60%
What is the CSTAT? PIP = 39, Pplat = 29, PEEP = 8, VTE = 480 mL (0.48L), MVe = 10.6,
RR = 22. - ANSWER: CSTAT = VTE / Pplat - PEEP
480 mL/ 21 = 23
What is the Raw? PIP = 39, Pplat = 29, PEEP = 8, VTE = 480 mL (0.48L), MVe = 10.6,
RR = 22. - ANSWER: Raw - PIP - Pplat / V
39-29 / (50/60) = 12
