Revision (Clinical Engineer)
Define :
1-Clinical engineer
2-Hospital engineer
3-Clinical and hospital equipments
4-Four typical responsibilities of clinical engineer
Complete
1-When biomedical engineer works within a hospital or clinic, they are properly called clinical engineer
2-Supervision ,training of medical personnel equipment inventory are typical Engineering responsibilities
3-Safety is a condition of being safe from Injury ,damage and danger
4-Risk Management Helps hospital to Avoiding exposure risks Minimizing liability
5-Healthcare technology includes the devices, equipment, systems, software, supplies, pharmaceuticals,
biotechnologies, medical and surgical procedures
6-Technology life cycle is a process by which technology is created, tested, applied, and replaced or
abandoned
7-Use the technology life cycle in understanding and analyzing healthcare technology.
8 Healthcare engineer, hospital engineer, biomedical equipment technician are other terms specifying
“clinical Engineer”
9-Cost-Effectiveness is a process that combines qualitative and quantitative considerations in order to
know the costs of a project compared to the resultant benefits.
10-Maintenance is divided into two corrective and preventive
13-Heart contracts generating action potential.
14-The spreading electrical currents create potentials differences which can be detected through surface
electrodes
15-The waveform of ECG produced is called the electrocardiogram
16-Three distinct waves are produced during cardiac cycle P wave, QRS complex ,T wave
17-The isolation circuit of the ECG is designed to isolate signal and line power source by using
an optical method
20- For electricity to have an effect on the human body:
i-An electrical potential difference must be present
ii-The individual must be part of the electrical circuit, that is, a current must enter the body at one point
and leave it at another.
21- Any procedure that reduces or eliminates the skin resistance increases the risk of electrical shock
b -Put ( √ ) or ( × ) and correct wrong statement.
( These are correct statements)
1-Technology audit & action plans are full clinical engineering implementation.( )
2-Clinical Engineer Departments is The logical support center for all medical technologies.( )
3-Healthcare engineer, hospital engineer, biomedical equipment technician, Other terms used to specify
clinical engineer ( )
4- Inventory is applied to medical equipment and facilities and accessories and state of conservation ( )
5-Personal Management helps the hospital’s maintenance and engineering staff be involved and prepared
to execute its functions ( )
6-Quality of Care means providing healthcare with the most efficient use of resources. (
)
7-The clinical Engineering Department should create specific criteria that reflect the Hospital’s needs
8-Process Management defines how workers and patient can have benefits from processes. (
)
9-Quality Assurance (QA) & Quality Improvement (QI) are formal sets of activities to measure the
quality of care ( )
10- Market Procurement Improve the knowledge of medical equipment market. (
)
11-In Cost-Effectiveness, Costs are normally expressed in dollars Benefits in terms of: Lives saved ( )
12- Any procedure that reduces or eliminates the skin resistance increases the risk of electrical shock ,
including biopotential electrode gel ( )
13- To protect patients from shocks completely isolate and insulate patient from all sources of electric
current ( )
_____________________________________________________________________________________
a-Draw the Block Diagram of ECG Measurement Circuit
b -What is the function of :
The lead selector circuit contains a voltage follower circuit (OP1 and OP2) to match impedance between
the electrode and skin , and increase the input impedance of the selector
Pre-amplifier: An instrumentation amplifier with a gain of 100 is applied as the preamplifier to catch the
unipolar signal from the ECG vectors
Isolation circuit The isolation circuit is designed to isolate signal and line power source by using
an optical method
c- What is the 6 types of leads
d- Mention one if the ECG Faults and its troubleshooting
What is the ECG?
What is the result of the ECG (draw the graph and indicates each wave and interval)?
State the main parts of the ECG machine parts and its functions
What are the two major ways to protect patients from shocks?
To protect patients from shocks completely isolate and insulate patient from all sources of electric current
What is meant by Einthoven’s triangle
The positioning for leads I, II, and
III were first given by Einthoven.
Form the basis of Einthoven’s triangle
Define :
1-Clinical engineer
2-Hospital engineer
3-Clinical and hospital equipments
4-Four typical responsibilities of clinical engineer
