Mr. Hall 6’ 2” and is being mechanically ventilated due to respiratory failure and complicated by ARDS. The following are the patients ventilator parameters and abg results:Mode    A/C                        Total rate             12                       pH            7.22Rate      12 breaths/min      PIP                      45 cm H2O       PaCO2      63 torrVT         550 ml                    Plat                      40 cm H2O       PaO2         51 torrPEEP    0 cm H2O                                                                       HCO3       26 mEq/LFIO2      0.80                                                                               BE            +2                                                                                                     SaO2         83%                                                                                                     Hb            15 g/dlWhat is this patients CaO2?

Calculate the PAO2 for a patient breathing room air with a barometric pressure of 760 mm Hg. FiO2 is 21% and PaCO2 is 40 mm Hg

How does the pulmonary vessels react to regional lung hypoxia?

When a patient has the following  rhythm, the most immediate action to perform would be:

A normal PaCO2 level is?

Interpret this ABG:pH – 7.25PaCO2 – 65 mmHgHCO3 – 24 mEq/LBE/BD – (+1)

An SpO2 reading should not be trusted in the presence of :I.  30% COHbII. Chronic bronchitisIII. PneumothoraxIV. Methemoglobinemia

Interpret the following ABG pH – 7.34 pCO2 – 60 HCO3 – 30

Interpret this ABG:pH – 7.50PaCO2 – 30 mmHgHCO3 – 29 mEq/LBE/BD – (+5)

For acid/base balance the _________ is reponsible for releasing or retaining PaCO2 to offset the bases in the body.
