KETTERING CALCULATIO

QuestionAnswer
TABACCO PACK YEARS PACK YEAR = # OF PACKS/DAY X # OF YEARS SMOKED
CEREBRAL PERFUSION PRESSURE CPP = MAP - ICP
ESTIMATEDE HEART RATE FROM ECG TRACING HEART RATE = 300 / #OF LARGE BOXES BETWEEN R WAVE OR = 1500 / # OF SMALL BOXES BETWEEN R WAVE AND
PULSE PRESSURE SYSTOLIC PRESSURE - DIASTOLIC PRESSURE
MAP (2 X DIASTOLIC) + SYSTOLIC / 3
CARDIAC OUTPUT (FICK) QT = VO2 / C (a-v)O2 X 10
CARDIAC OUTPUT (STROKE VOLUME) QT = HEART RATE X STROKE VOLUME
STROKE VOLUME QT / HEART RATE
CARDIAC INDEX CI = QT / BSA
SYSTEMIC VASULAR RESISTANCE (MAP - CVP) / CARDIAC OUTPUT
PULMONARY VASCULAR RESISTANCE (MPAP - PWP / CARDIAC OUTPUT
PAO2 (PB - PH2O) X FIO2 - PACO2 / 0.8 OR PACO2 X 1.25
A - a DO2 PAO2 - PaO2
CaO2 HB X 1.34 X SAO2 + PAO2 X 0.003 OR HB X 1.34 X SAO2
CvO2 HB X 1.34 X SVO2 + PVO2 X 0.003 OR HB X 1.34 X SVO2
C (a-v) CaO2 - CvO2
QT VO2 / C (a-v)O2 X 10
VO2 QT X C (a-v)O2 X 10
OS/QT (A-aDO2) X 0.003 / (A -aDO2) + C (a-v)O2
SAO2 PAO2 + 30 (WHEN PAO2 IS BETWEEN 40-60 TORR
OXYGEN INDEX ( OI) PAW X FIO2 / PAO2 X 100
VD/VT PaCO2 - PECO2 / PACO2 X 100
DESIRED MINUTE VOLUME VE X PaCO2) = VE X PaCO2
SUCTION CATHETER SIZE TUBE SIZE / 2 X 3 OR TUBE SIZE MINUS 1 / 2 TAKE THE NEXT DOWN
LITER FLOW TO PERCENT LITER FLOW X 4 PLUS 20
PERCENT TO LITER FLOW (PERCENTAGE - 20) DIVIDED BY 4
DURATION OF TANK GAUGE PRESSURE X TANK FACTOR / LITER FLOW E = 0.28 OR 0.3 H = 3.14 OR 3
IDEAL BODY WEIGHT 50 K +(2 X INCHES OVR 5 FOOT)
ESTIMATED TIDAL VOLUME (VE +FLOW)
MINUTE VENTILATION VT X RR OR VT X F
ALVEOLAR MINUTE VENTILATION (VT -VD) X F OR RR
DYNAMIC COMPLIANCE VT / PIP - PEEP
STATIC COMPLIANCE VT / PLAT - PEEP
AIRWAY RESISTANCE RAW PEAK PRESSURE - PLATEAU PRESSURE
WORK OF BREATHING CHANGE IN PRESSURE X CHANGE IN VOLUME
RAPID SHALLOW BREATHNG INDEX (RSBI) RR / VT IN LITERS

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
