Mobiles Flashcards
What are the 2 types of Of mobile machines?
Analogue
Digital
What are features of analogue mobile machine?
power
drive
Analogue - Battery or mains powered manual or motor asists drive mechanism
Main features of a digital mobile machine?
Wired detector
Wireless detector
What are essential features of mobile machines?
High quality image production
Shock resistant material
Manoeuvrability (tight spaces)
Small footprint/compact (tight spaces)
Lightweight (long distances)
Radiation protection
Infection control
How does battery power affect image quality?
It is essential the mobile machine has sufficient energy to take to complete a sufficient exposure to ensure good image quality
How is battery energy managed on mobile machines?
Battery monitor (Mains independent) – (It is essential that the battery is always charged)
ensures sufficient power is available for exposures; Mains power available when battery life insufficient to make exposure
What does APR stand for and how does it ensure it good image quality?
APR – add atomically program Radiography - preset exposure factors
ensures effective selection and reproducibility of exposure
Also allows for ALARA to be achieved
What are angle indicators and how do they help produce good image quality?
Angle indicators ensures correct angle is being used for positioning purposes which provides reproducibility
A tape measure is also used to ensure correct SID
How are mobile machines shock resistant?
They Are made of:
Shock resistant material
Antistatic wheels
Earth connection - which insures electrical safety during operation

What are the design features of mobile machines to ensure effective movement?
They are:
Lightweight – battery
Manual/motorised drive
Multi directional/pivoting wheels
 Wide base plate - Balance (ergonomically designed)
Reliable breaking
Storage hopper – transporting image plates and pads et cetera
Collisions detector – stops mobile x-ray unit
Durability – able to cope with hospital environment in and out of lifts, ramps and doorways
What radiation protection is used to ensure safety with mobile machines?
Keylock – IR(ME)R 2017
Exposure at long distance
– Either long cord (2 m)
– remote control (up to 10 m)
Emergency stop button – prevent further exposure in till overridden
DAP meter
Lead rubber court holder/hook
What are some other technical safety features on the Mobile machine?
Retracting charging cable
Hopper for images plates et cetera
What infection control should be considered with mobile machines?
Hygiene – MRSA, blood Etc.
easy to clean
Are there any danger areas not readily cleaned
Cleaning agent/disinfectant
Plastic covers for image play/detector
What are some different aspects of digital mobile machines?
Instant images – three seconds
Detector can be wireless
Slightly larger and heavier
Barcode reader
DICOM right (digital imaging and communications in medicine) compatible
Flat panel detector (FPD)
Why would mobile need to be used?
The biggest reason why a mobile would be needed is because the patient is unable to come down to the department:
This can be due to many reasons such as:
Suction
Pacing
Level of consciousness
Traction
Monitoring
Ventilated

Why is it essential that there is a valid reason for a mobile to take place?
If the reason is not valid it is taking away resources which could be essential somewhere else
What are some appropriate clinical indications for a mobile x-ray?
Cardiac/respiratory arrest/distress
Decreasing SATs (oxygen saturation)
Placement or repositioning of tubes
Placement of lines
Trauma call (Resus)
Post surgery

What body parts are more common and less common to be mobile xrayed?
Chest (most common)
Abdomen – Less common
Pelvis – trauma
C-spine – trauma
Law/upper limb – trauma
T/L spine – trauma, rare
Skull – very rare, not justified
Always follow department protocols
How does the initial request go for mobile x-ray?
Phone calls/pager system
Must justify the mobile request
Why is it a mobile request?
Can it be done in department?
When is it needed?
Request form!
What are the considerations you must be taken into Account before you set off for a mobile x-ray?
How many staff are needed?
Which mobile machine is closest?
Have you remembered the key?
Location of ward
Word access
How many other mobiles?
Accessories – phone pads, sandbags, grid?
Don’t forget the inverse receptor or a request card!
Infection control?
How to achieve good Infection control of mobile machines?
Hand washing
Use of alcohol gel
Alcohol wipes
Cleaning of mobile machine
Imaging plate covered
Use of accessories and cleaning them
PPE
Changing gloves etc between patients
Barrier nursing
What radiation protection techniques to be seen in wards?
What other aspects of safe practice do we need to consider?
These for example questions in the PowerPoint I just can’t be bothered answering them right now yay
What technique and considerations must be taking into account with mobile machines?
Patient positioning – EP or PE correct Erect are Supine
Easy slides
Nurse assistance
Specialised beds
Hyderabad – pressure sores + burns patients
What considerations do you need to take into account in intensive care (ITU, ICU, HDU)?
Physiotherapy and chest care - It will be busy need to try and stay out the way I get in when you need to be
Sedation - Lots of people will be Unconscious
Communication - you will have to try and communicate with different members of staff from different teams as well as with patients who may not want to be very communicative
Infection control - It is essential that infection control is taking very seriously as people are very ill and have an increased risk to infection
Lines and catheters - You must be aware of all the lines of catheters to ensure that they are not trip hazards
as well as ensuring safety to the patient
