When setting PEEP based on a pressure-volume curve, the optimal PEEP should be 1-2 cm (above / below) [BLANK-1] the (Lower inflection point / Upper Inflection Point) [BLANK-2].

An order is written for a PEEP reduction test where the initial PEEP is 12, FiO2 40%. Initial PaO2 is 90 mmHg. The PEEP is then changed to [BLANK-1]. Following the test, the minimum PaO2 to consider this a successful PEEP reduction test is [BLANK-2].

A patient is being managed on a volume ventilator with the following settings: Vt 850 ml Rate 10 MV 8.5 L FIO2 35% The following ABG’s on these settings are 7.3/53/51/24/85% Based on this information, what should the therapist do?

See the following PV loops. In both situations, assume the patient is receiving volume controlled ventilation with a set VT of 600 mL. Which patient, A or B, has worse (lower) compliance?   mvt36.jpg

An apneic 55 kg (IBW) patient is being ventilated with a volume ventilator in the CMV mode. Her vent settings are as shown: Rate 12, Vt 550, FIO2 60%, Mechanical deadspace 75 mL Her ABG’s show 7.32/52/56 Considering this information, all these individual ventilator adjustments would improve her ABG’s EXCEPT:

A 28 year old man presents in the ER after being involved in an MVA. The patient sustained multiple rib fractures bilaterally. Vital Signs: Spontaneous Ventilatory Parameters HR 120 Vt 200 BP 160/100 VC 500ml Temp 98C. Blood Gas results on RA 7.21/75/50/26/84%.  Thirty minutes after initiating mechanical ventilation, the following ABG’s are obtained on 40% 7.29/58/160/25/99%  Which of the following would be MOST appropriate interventions for this patient?

You are ventilating an adult female with a Hamilton-G5 in APVcmv. Her weight is 120 lb (IBW) and her settings are: Rate 14 (patient is assisting at 20), Vt 800ml, FIO2 30%, Itime 1.2 seconds, PIP 38, Pplat 30, PEEP 5ABG’s on these settings are 7.49/32/58/23/89% What would be the most appropriate change (if any) to correct the PaCO2? What would the new setting be? What change would be the most appropriate (if any) to correct the PaO2 and SaO2? What would the new setting be? What is the static compliance? Is it normal, high or low?

A 35-year-old patient is being mechanically ventilated with SIMV and these settings: rate 12, Vt 850, PS 16, 45% FIO2. He is not breathing spontaneously. Based on these settings, he has the following ABG’s 7.5/29/94/23/98%.  The physician is not pleased with these values. What would you recommend to correct them?

You are working with a 176 lb patient who is apneic after suffering a stroke. He is being ventilated in CMV mode with the following settings: MV 8 L Rate 10 I:E 1:3 FIO2 40% Mechanical dead space 200 ml The ABG’s show 7.3/50/90/24/95% You would recommend which of the following:
