1
positive ventilation
bowels law fialure, key forms of positive venitlation. invasive ventilation and non invasive, (BIPAP)
2
In picture there is:
haemofiltration machine
sering drivers
screen for patient info
a lines
drip stands
patient observation machines
tubing wiring
3
levels of care
three levels of patients we have in hospitals:
level 2 - cardiac patients, HDU style stuff, regular observations but not in multisystem failure. may needmechanical ventiliation
level 3 - at least 2 organ systems failing, RER? These patients need machanical ventilation .
4

definttion
5
why you need mechanical ventilation?
resp
fatigue from beingin type 1 for a long time, breathing fast for long time
altered drive - drug over dose, alcohol
peri operatively - for major surgery
6
type of eg tubes
goes into the airway
can be nasal intubation thoguh trachea, goes below vocal chords whcih means they cant speak
inflate cuff to keep it safe.
dont want it to go too far down into the bronchus
careful when moving ptient with a tube
7
mechanical venitlation principles
positive pressure
type 1 and 2 resp failure.

11
presreu control vs volime control
volumedependant on complaince...
you can set one but you ned to check the other one
12
ventilation mode
SIMV - ocntrol them completly
bilevel - two pressures, set a pressure so doesnt go all the way down to 0
PEEP - not letting them breath all the way out
Trigger - set trigger low, so patient can breaht if they want to
Pressure support
Rise time
** look at notes below slides
13
ventilation strategies
hypervenitltion to help with brin swelling
**again lok at notes below slides on powerpoint
14
extubation and weaning
pressure support - everytime they take a breath the ventilatier will support them but gradually reduce that support and peep (lowest peep of 5). then just give them peep during insp and exp and gradually wean og the peep support so patient can breath on their own.
** find lecture recording for this as explanation isnt good
15
wean
simple
difficutl - may not be awake
prolonged - like covid patients that are very weak, resp and also their muscles very weak
16
subjective markers
are they awake?
...
17
objective markers
maximal insp pressure mip
use them to help us judge if someone is extubational or not? PCF main one
18
key predictors
pcf main one. as long as great than 60lpm, if less then theyll fail extubtation.
if not meeting all these markers than their 80% of failing
19
problem patients
more complex patients.
these things (on the slide) that make things like weaning more difficult
20
weaning, what is it? reasoning
look up
its a physio thing to do
21
ICUAW
icu required weakness
these notes are befreo covid so will be more icu patients affected - see in notes
22
muscle mass
muscle waste. icu rehab is alot on muscle mass. in order to wean patients we need that msucle mass. think about the covid patients in icu since christmas- lots of loss of mass
23
diagnosis
cip cim cinm
shows your weak presentation of muscles. so you can,
24
prognosis
over time muscle mass will improve. muscle takes time to regenerate, need or icu follow up to check this regeneration of muscle mass
25
reaseach around it and evidence of icu rehab - it is very safe. treatment - photos
see and make notes on the other slides she missed.
26
weaning
if surgical patints check patient check fluid balance and so on then sedate them agin. if they respnd an can do all tests plus neuro tests then start the weaning process.
27
words to search up
delerium. benzos
type of sedations. oonly sedate patient enough to be in sinc with ventilator
