At what level of intracranial pressure will result in brain death?

The resistance that the RV and LV work against to push blood through the vascular system is:

Mr. Rainout is a patient with a long history of COPD, presents to the ED with an exacerbation precipitated by bilateral pneumonia which resulted in Mr. Rainout to be placed on a mechanical ventilator. He has been in the MICU for the past 4 days with very little noted improvement on his condition. The following parameters are measured:PB = 754 torrVent Settings: A/C 14, Vt 430 mL, PEEP 12 cmH2OpH = 7.29PaCO2 = 83 torrPaO2 = 48 (SaO2 = 64%)PvO2 = 33 (SvO2 = 32%)Hb = 18.9 g/dLFiO2 = 0.30QT = 3.7 mL/mina. Calculate the alveolar air.b. Calculate the P/F ratio and state what it indicates.c. Calculate the total oxygen delivery in one minute.

During bedside assessment of a patient with a PAC, the respiratory therapist in the MICU notices a dampened waveform on the monitor of the arterial line. To restore the graphic to normal, the RT should FIRST:

What will the MAP be if the systolic blood pressure is 93 mm Hg and the diastolic blood pressure is 60 mm Hg?

BONUS: What is considered the hallmark of cardiac contractility?

Mr. Jim Bean is a 69 YO male who has undergone CABG X4 and is being hemodynamically monitored is currently on mechanical ventilation. Based on the following recorded parameters, what is the the patient’s oxygen consumption?pH 7.37, PCO2 48 torr, PO2 240 torr, SaO2 95% on 100% O2Hb 15.2 g/dLPB 750 torrPvO2 51 torr (SvO2 49 torr)QT 4 L/min

Where is the PAC placed, if the waveform on the monitor is “B”

What position is the Swan-Ganz catheter, if it is displaying the waveform on “C”?

Which of the following conditions are commonly associated with an inadequate expiratory time?I. airtrappingII. Auto-PEEPIII. appropriate flow rateIV. low mean airway pressure
