what is the area of positive pressure
area where operation should happen in a specific area of ventilation system where it blows out from site rather than in

blue scrubs
head covering
shoes
what are the 5 rules to wearing blue scrubs as part of perioperative practice

not into the semi or full restrictive areas of the perioperative suite

yes can be carried but not to be accessed in theatre while you are working, only access them during break times
what should you always wear in terms of PPE
gloves
what should you ideally wear in terms of PPE

sterile fields
where should you never walk through in a operating theater
between sterile fields
how should contaminated items be picked up in an operative theater
only if your wearing gloves
what should you be careful about in terms of positioning over sterile field in an operative theater
never position over sterile field without sterile II cover

lines and tubes
what should you never adjust in a operative theater
never adjust the ventilator or bed heigh/position
who is the captain of the ship in an operative theater
the anesthetist
how is radiation protection managed in an operative theater - 5 things
understand collimation
communicate
protect everyone in room
use filter factors like metal correction
dose monitoring badges
what should you do to pulse rate if live screening in terms of radiation protection
reduce pulse rate if live screening
where should the II be in terms of radiation protection
II always close to subject
having the II close to the subject is a radiation protection measure in what 4 ways
increases FOV
reduces dose
reduces scatter
image quality
what is the default position of the II and tube
default is II on top and tube at bottom
if II is on top what is the buttons on/off
either both on or both off
when ever the tube is on top how many Rs need to be on
one
If tube on top, why don’t want to screen anything that is dense such as chest or abdomen area (extremities are fine)
due to dose (only time you do that is when you need to go over the patient rather than under the patient to give lateral
If II is on top what kind of hori ray can be done
under the table hori ray
if you go over the field, what kind of view can you take
only go 45 degrees and can only do obliques
if you want a lateral view going over the top they what component of the tube needs to be ontop
tube needs to be ontop
what is panning movement of the C arm
whole C arm moves side to side horizontally
what is the continuous pulse fluoroscopy button used for
activates continuous pulse fluro mode and displays the pulse rate setting controls in the dynamic control area
what is the high quality button used for
activates the high quality supplementary function
what is the caution of using the high quality button
reduce the radiation time
what is the snapshot button used for
activates the snapshot mode
what is the bones button used for
activates the anatomical program for visualizing the heart and thorax region
what is the heart button used for
activates the anatomical program for visualising the heart and thorax region
what is the abdomen button used for
activates the anatomical program for visualising the abdominal region
what is the metal button used for
activates the metal artifact correction supplementary function
tells II there is metal present so needs to increase exposures to avoid giving extra dose
do high quality and single shot have the same exposure and what is the difference between the 2
High quality and single shot have same exposure but high quality can livestream while single shot is just a photo
what does the save button do
saves the active image to the hard disk
what does the laser button do
activates or deactivates the laser positioning devices
what does the magnify button do
shows or hides the controls for setting the image intensifiers electronic magnification in the dynamic control area
the buttons always show the current image magnification level
what does the text button do
activates the text mode
what does the greyscale inversion button do
displays the active positive image with a negative grayscale or vice versa
when are the text and greyscale inversion buttons used
in post processing
what is the manual exposure rate setting button used for
enables manual setting of tube voltage and tube current
what is the large patient button used for
activates the large patient supplementary function to adjust to patient body size and habitus
what is the cine button used for
activates or deactivates the cine loop mode
what is the image swapping button used for
swaps the images between the live and reference monitors
what is the rotate image CW button used for
rotates the image in a clockwise direction
what is the rotate image CCW button used for
rotates the image in a counter clockwise direction
what happens in a ziehm vision FD machine to the image when it is rotated
image assumes a circular shape when rotated
what is the rotate image to 0 degrees button used for

what is the reverse left/right button used for
mirrors the image horizontally around the vertical axis
