Equations
PaCO2 = 50, PeCO2 = 40. VD/VT is this.
What is 20%?
(Hb x 1.34 x SpO2) + (PaO2 x 0.003)
What is the oxygen content equation?
This critical value is 10 - 15 ml/kg
What is vital capacity?
7.25 / 57 / 80 / 23 on RA is called this.
What is uncompensated respiratory acidosis with no hypoxemia?
The minimum number of time constants needed in the exhalation phase (Te)
What is 3?
PaCO2 decreases from 40 to 30 mmHg. Initial bicarb was 24. The new bicarb value is.
What is 22 mEq/L?
Patients who are fluid resuscitated will have this type of hematocrit value.
What is abnormal or low?
This critical value is < 7.25
What is pH?
7.16 / 22 / 70 / 18 on RA is called this.
What is partially compensated metabolic acidosis with mild hypoxemia?
At 4 time constants this % of alveoli will have emptied during exhalation.
What is 98%?
RAW = 13 cmH2O/L/sec, compliance = 40 ml/cmH2O, Time constant is this value.
What is 0.52 seconds (must convert ml to L)
FIO2 goes up by this amount when patient's temp increases from 38 to 39C.
What is 10%?
The critical value is 0.6.
What is the ratio of tidal volume to dead space?
7.35 / 20 / 55 / 19 on RA is called this.
What is fully compensated metabolic acidosis with moderate hypoxemia?
An obstructive disease associated with high RAW and very high compliance.
What is emphysema?
The normal A-a grade is this value.
What is 5 - 15 mmHg?
The oxygenation problem is located here when the A-a gradient is wide.
What is the alveolar capillary membrane?
This critical value is > 450 mmHg.
What is the A-a gradient?
7.48 / 29 / 70 / 26 on RA is called this.
What is uncompensated respiratory alkalosis with mild hypoxemia?
This times this = Time Constant value.
What is RAW and compliance?
PaO2 = 52, FiO2 = 40%, desired PaO2 = 65. The FiO2 should be set at this.
65 mmHg x 40 / 55 mmHg = What is 50%?
The oxygenation status for a patient with PaO2 = 52 mmHg on 100% FiO2.
What is moderate as well as severe? (P/F is severe)E Either answer OK, depending on perspective
This critical value is < -20 cmH2O.
What is MIP? NIP or equivalent
7.12 / 55 / 38 / 17 on 100% FiO2 is called this.
What is mixed acidosis with severe hypoxemia?
Severe pulmonary fibrosis has this type of time constant.
What is short or small?
