Vent Cheat sheet – Flashcards

assisted breath only on inspiration. gives a bigger breath which increases VT

pressure on expiration. lowers WOB and allows lungs to stay open to restore FRC

*Controlling* the patient. Vent doing ALL work. Pt is typically very sick when you need control. Support modes are used when the patient can function somewhat on own.

SET Volume and SET Rate. Can breathe spont @ the SET Volume. Pressures are variable. Better ABG's with a set volume

Used For Barotraumas and Pts at risk of Pneumo. You set a CONTROLLED (set) pressure to make sure you don't further damage the lung. Pressure is SET Rate is SET. Spont breaths can be taken @ SET pressure. Variable Volumes... ABG's not consistent

Why does it have pressure? it can be used *spontaneously* spont breaths is when pressure Support is used to assist the breath in. give a bigger VT.

SET rate..SET Volume. Anything Spont will be spont pressure and volume but with the help of Pressure support to get bigger VTs

2 levels of PRESSURE (what does pressure do??) increases FRC and improves Oxygenation. Holds lungs open. pt is on higher level most of the time.

Pressure on Inspiration. helps with Ventilation

pressure on Exhlation. helps w/ oxygenation

Pressure SUPPORT. Ipap 10 minus EPAP 5 = 5 of PS. I 15 - E 5= 10 PS

BI= 2 levels. IPAP and EPAP. IPAP works on Ventilation EPAP is PEEP (Oxygenation.) use on pt with an ABG that needs help in both areas. c02 of 50 and o2 of 80

Same as PEEP. Improves oxygenation. Use for a Patient that has a normal Co2 but needs help oxygenating

co2 is a DIRECT relationship. If HIGH, Increase Rate (if plat is near 30 or is VT is already too high.) If VT is in range change VT

FI02 or PEEP. FIO2 <60. Increase FIo2 before PEEP. room air is 21% over 60 is HIGH fi02. if over 60 use PEEP unless contraindicated

Peep Lowers BP, Lowers Cardiac Output, Increases ICP. If pt has low BP dont use peep. low CO= NO peep. high ICP= NO peep

don't use peep, only option is to increase fio2 because peep in CONTRINDICATED

VT is already out of range... leaves one choice. Rate. Plat is too high to increase VT anyway

increase Rate because plat is high. VT is in range and if plat wasn't high you could increase VT but since plat is high increase RATE

Which side of the line do you fall to? Like a teeter totter... does is weight more towards extubate or intubate (KNOW YOUR #'s)

pt doesnt have enough time to exhale. to fix.. decrease RR (more time to exhale,) decrease VT (less to blow out,) Increase Flow (get it in quicker). pt ultimately needs more time to Exhale

MIP and FVC

<30 (note plat with High CO2.)

<50. Peak of 50 is high!!

Resistance to flow. flow can't get through.. Small ET Tube think about drinking out of a coffee stirrer vs a straw. or something is in the way. pt is obstructed. suction them or remove foreign object
