Tidal volume from predicted weight, plateau and driving pressure capped, PEEP from the ARDSNet table, prone sessions and a written breathing-trial gate make up this NU656 Unit 6 plan. Searches like "nu 656 unit 6 assignment example", "nu656 unit 6 sample" and "nu656 unit 6 example" land here.
What a finished NU656 Unit 6 ventilator management plan looks like
Three pages centered on a settings table. Its rows are mode, tidal volume, respiratory rate, PEEP, FiO2, plateau pressure, driving pressure and targets for oxygenation and pH; its columns give the value, the reason, the recheck time and the condition that would change it. The case paragraph above the table sets the diagnosis: a PaO2 of [74] mmHg while breathing [70] percent oxygen at a PEEP of [10], a ratio near [106], moderate ARDS by the Berlin definition. Tidal volume starts at [330] mL, [6] mL/kg of [55.1] kg, then falls to [275] mL when the driving pressure reads [17]. A paragraph on prone positioning cites PROSEVA (Guerin and colleagues, NEJM, 2013). The breathing-trial gate closes the plan, its conditions drawn from the ARDS Network protocol and the 2017 ATS/CHEST liberation guideline.
How a NU656 Unit 6 example is structured
Calculation comes first because every protective setting derives from it: the plan shows the predicted body weight formula for women, [45.5] plus [0.91] times height in centimeters minus [152.4], and works it to [55.1] kg. The table then reads left to right as an argument. Tidal volume and plateau pressure are justified from the ARDS Network trial of 2000 and the 2017 ATS/ESICM/SCCM guideline (Fan and colleagues), which recommends [4] to [8] mL/kg and a plateau below [30]. Driving pressure, plateau minus PEEP, gets its own row, supported by Amato and colleagues (NEJM, 2015), and its reading of [17] is the reason tidal volume drops to [5] mL/kg while rate rises to [30], keeping minute ventilation near [8.3] liters. PEEP follows the lower PEEP/FiO2 table. Prone positioning is triggered by the ratio staying below [150], and weaning is gated by stated numbers.
The weight that sets everything
Actual weight [88] kg, height [163] cm, predicted weight [55.1] kg. The plan shows the formula and the arithmetic in one line, because a tidal volume from the scale weight would be [528] mL, roughly [60] percent larger than intended.
Pressures that cap the breath
Plateau pressure is checked after every tidal volume change with an inspiratory hold, and driving pressure is recorded beside it. A driving pressure of [17] prompts the move to [275] mL; the recheck reads [24] over PEEP [10], a driving pressure of [14].
PEEP chosen from a table, not a feeling
At an FiO2 of [0.70] the lower PEEP/FiO2 table allows [10] to [14] cm H2O. The plan keeps [10], states the oxygenation goal of a PaO2 between [55] and [80] mmHg, and names the FiO2 step at which PEEP rises.
Prone, with a trigger and a duration
A ratio still below [150] after [12] hours of optimized settings starts prone sessions of at least [16] hours. The plan cites the PROSEVA inclusion criteria and records the ratio of [160] after the first session as the measure of response.
The gate to a breathing trial
FiO2 at or below [0.40] with PEEP at or below [8], spontaneous effort, no rising vasopressor need and a sedation pause tolerated. When all are met, a trial on low pressure support is due that morning, not at the team's convenience.
Where marks go in NU656 Unit 6
Numbers without reasons earn little here. A table giving a tidal volume of [330] with no predicted weight beside it leaves the figure's origin unknown, and instructors treat that as the central weakness. The weight itself is the commonest error: tidal volume set from actual weight in a patient of [88] kg is marked as a protective-ventilation failure regardless of what follows. Plateau pressure should be measured, not assumed, and a plan that never mentions driving pressure misses the reason for the second tidal volume change. PEEP chosen without reference to a table or an oxygenation goal reads as arbitrary. Prone positioning named without its trigger or its duration earns partial credit. Weaning criteria left as when improved, rather than as numbers, cost a final share.

Height, sex, the admission gas and the ventilator settings from the NU656 Unit 6 case, plus your rubric, are all it takes. The plan follows within 24-48h, free as a first request, setting each value beside its reason, a recheck time and the reading that would alter it.
NU656 Unit 6 questions, answered
Why does the plan use predicted rather than actual body weight?
Lungs scale with height and sex rather than with body mass, so a heavier patient does not have larger lungs. Predicted body weight comes from a formula using height, and protective tidal volumes are set per kilogram of it. The sample shows the calculation for this composite woman and the size of the error that actual weight would have introduced into every later setting.
What is driving pressure, and why add it to the table?
Driving pressure is plateau pressure minus PEEP, a rough measure of the strain each breath places on the lung that remains open. In a pooled analysis by Amato and colleagues, it was more strongly associated with survival than tidal volume or plateau pressure alone. The sample records it after each change and uses it to justify lowering the tidal volume.
Are these settings meant for a real ventilated patient?
No. They belong to an invented patient, and each figure is a bracketed placeholder. Ventilator orders for real patients come from the treating team, the respiratory therapists and the unit's protocols. The sample shows how a plan ties each setting to its reason and its recheck, which is the reasoning coursework in this unit is typically graded on.
