A 28-year-old female (65-kg IBW) is being mechanically ventilated with VC-CMV, f = 14/min, VT = 700 mL. The patient has no history of pulmonary disease. The resulting ABG values are: pH 7.55, PaCO2 27 mm Hg, HCO3- 23 mEq/L. The most appropriate action to take is which of the following?

What is the optimal PEEP level given the following information? Time 0700 0710 0720 0735 0740 0755 PEEP 0 5 8 10 12 15 P(a-et)CO2 11 10 6 13 15 15   26 28 34 30 27 25 BP 138/90 128/93 120/86 100/70 100/70 105/75

If respiratory acidosis persists after alveolar ventilation of a patient has been increased, which of the following could be the cause?

Enter the GAAP terminology next to the correct description. [a]: if the value of an item is not significant, then other accounting principles may be ignored if it is not practical to use them [b]: financial statements must be prepared in a specific currency denomination [c]: requires that footnotes on the financial statements disclose any past or future events that could affect the financial health of the business [d]: expenses incurred should closely match the actual revenue those expenses generated [e]: a business’s financial transactions must be kept completely separate from those of the owners [f]: the time period of the financial statements must be reported [g]: there must be evidence (i.e. sales slips, invoices, guest checks) to back up the financial transactions reported [h]: the assumption that the business will be ongoing indefinitely and therefore assets are recorded at the price paid and not replacement value [i]: all business transactions must be recorded at their cash cost [j]: a business must consistently use one system to record transactions [k]: accountants must be conservative when reporting revenue and realistic when reporting expense and other liabilities

To help prevent inflated alveoli from collapsing and reexpanding with each breath, the positive end-expiratory pressure (PEEP) level should be set at which point on the deflation part of the loop?

Calculate the alveolar volume (corrected tidal volume) delivered to the patient when the tubing compliance (CT) is 2.5 mL/cm H2O, the set tidal volume (VT) is 550 mL, and the peak inspiratory pressure (PIP) is 28 cm H2O.

During which phase of a capnograph does alveolar gas containing carbon dioxide (CO2) mix with gas from the anatomical airways and the CO2 concentration rises?

What size suction catheter is appropriate for use in a patient with a 7-mm ET tube?
