Mech Vent Unit 5
SPC Mech Vent Unit 5 - I AM'S
Question | Answer |
---|---|
I am positive pressure above baseline during exhalation: | PEEP |
I reduce the WOB caused by airways & am also used w/ CPAP: | PS(pressure support) |
I am the type of vent used w/ a post arrest pt: | Volume vent |
I can cause auto cycling: | Sensitivity too high (ex: -10) |
I am the recommendation for Vt: | 10-12 ml/kg |
I am a mode that helps avoid barotraumas: | PC(pressure control) |
I can be used to improve I:E ratio: | Increase flow, decrease rate - pressure - Vt |
I am a complication of PEEP: | Increased ICP, decreased BP - venous return - CO |
I am the 1st thing you should check when you increase PEEP: | BP, CO, ICP |
I am what you do if a pt is showing adverse effects to increases in PEEP: | Lower PEEP |
I am the primary purpose of PEEP: | Improved Oxygenation |
I am what should be placed on a SIMV pt that has an increased WOB: | PS(pressure support) |
I am what you can do on a vent to increase PaO2: | Increase PEEP or Increase FiO2 |
I am a vent setting that decreases shunting: | PEEP |
I am what you can do on a vent to lower the CO2: | Increase Vt first then rate |
I am the effect of PEEP on FRC: | Increase or maintain FRC |
I use Vt's smaller than deadspace, rates greater than 60, & need special ET tubes: | HFV(high frequ. vent.) |
I am what will happen on a volume vent w/ bronchospasm: | Increase in Peak pressure |
I am what the distance between PEAK & PLAT airway pressures tell you: | Airway resistance |
I am another word for intrinsic PEEP: | Auto-Peep |
What mode is most likely used w/ decreased compliance: | PC(pressure control) |
I am the BiPAP adjustment that lowers CO2: | The difference between IPAP & EPAP |
I give the preset volume at the preset rate: | VC(volume control) (maybe SIMV) |
I give the preset pressure at the preset rate: | PC(pressure control) |
I augment/increase spontaneous Vt's: | SIMV-PS |
I adjust my own flow to give the preset Vt at the lowest possible peak pressure: | PRVC, VC+, Auto-flow |
I am the accepted range for Vt: | 10-12 ml/kg |
I am the accepted range for rate: | 8-12 |
I am how the initial FiO2 on a vent is determined: | PaO2>60mmHg & SaO2>90% |
I titrate/adjust the pressure support to give the Vt you want on spontaneous breaths: | VS(volume support) |
I am what would cause you to choose pressure control: | Trauma or ARDS |
I base my level of support on the settings for pt's WOB: | Proportional Assist |
I determine how hard the pt has to work to get a breath: | Sensitivity |
I am the value that starts exhalation: | Cycling |
I mix oxygen & air to provide a specific FiO2: | Blender |
I save moisture for the pt's next breath: | HME |
I am an immediate complication of oral intubation: | Tooth trauma |
I am ventilation w/o perfusion: | Deadspace |
I am the normal level of deadspace: | Normal 20-40%, Critical > 60% |
I am perfusion w/o ventilation: | Shunt |
I am a normal NIF: | -50 to -100, Critical < -20 to 0 |
I am a normal MEP: | Normal +100, Critical < +40 |
I am the minimal acceptable VC: | 65-75 ml/kg, Critical < 10 ml/kg |
I am a normal A-a gradient: | 5-15 (on O2) |
I am the types of ventilators: | Pneumatic & electronic |
I start inspiration: | Triggering |
I am the 3 types of things that are used for triggering: | Pressure, Flow, Time |
I am used for obstructive sleep apnea: | CPAP |
I am used to correct hypoxemia: | PEEP or FiO2 |
I am a mode that gives the preset volume only when vent wants: | Control |
I give the preset volume, the pt can spontaneously breathe, but spont. breath will only be given @ the set Vt: | VC(volume control), Assist Control |
I time my breaths w/ the pt's: | SIMV |
I am the types of laryngoscope blades: | Macintosh & Miller |
I am caused by too high a rate w/ too small a time to exhale: | Auto/Intrinsic PEEP |
I am the I:E ratio you should shoot for: | Normal on RA: 1:4, 1:3 on vent |
I am a complication of transporting a mechanically ventilated pt: | Extubation, low O2 |
I am the difference between volume controlled & pressure controlled ventilation: | VOL: vol stays same, pressure varies, set rate; PRESSURE: pressure stays same, vol varies, set rate. |
I am the accepted Ve range: | 5-8 L/m |
