Healthcare Technology & Function
A blood pressure cuff that is too small or too large will produce these types of inaccurate readings.
What are falsely high readings with a cuff that is too small, and falsely low readings with a cuff that is too large?
These specialized rooms are found in patient care areas to protect surrounding patients and clinical staff from the patient.
What is the purpose of a negative pressure room? (Isolation room)
This law describes the relationship between voltage (V), current (I) and resistance (R) in an electrical current.
What is Ohm's law?
This organ performs seven essential functions to the human body, including filtering blood, regulation of fluid balance and eliminating nitrogenous waste.
What is the Kidney
TJC
The Joint Commission
*The Joint Commission is an independent, nonprofit organization that evaluates, accredits, and certifies healthcare organizations to ensure they meet rigorous standards for patient safety and quality of care.
Acrylic nails or nail polish can interfere with this device resulting in an inaccurate SpO2.
What is a pulse oximeter?
*A pulse oximeter estimates oxygen saturation by shining red and infrared light through the fingertip and measuring how much light is absorbed by pulsing blood. When a patient has acrylic nails, the material can block, absorb or scatter the light causing the sensor to have a harder time detecting true blood signal.
The minimum retention force required for electrical receptacles in patient care areas.
What is 4 ounces?
These devices are worn by healthcare or radiation workers to track exposure to beta and gamma radiation over time.
What are film badges?
This is the largest part of the brain responsible for higher thinking, memory and voluntary movement.
What is the Cerebrum?
AAMI
What is Association for the Advancement of Medical Instrumentation?
*This organization develops standards for the safety and performance of medical equipment, including sterilization and sterilizer testing devices.
This refers to the two phases of blood pressure: one during heart contraction and one during heart relaxation.
What is systolic pressure (heart contracting and pumping blood out) and diastolic pressure (heart relaxing and filling with blood)?
*Accepted normal range 120/80 mmHg
Systolic contract + pump/diastolic - relax + fill
When a hospital loses power, the Automatic Transfer Switch (ATS) triggers, isolating the facility from the failed grid and signaling the backup generators to start. From power loss to generator power delivery, typically takes this long.
What is 10 seconds?
This equation shows how to calculate total resistance when three resistors are connected in series.
What is R1+R2+R3=RT ?
This specialized group of cardiac muscle cells generates electrical impulses that initiate each heartbeat and is known as the natural pacemaker of the heart.
What is the SA Node (sinoatrial node, also known as the sinus node)
CMIA
California Medical Instrumentation Association
*CMIA is dedicated to the promotion, education and information exchange of the state's clinical biomedical engineering community.
This is the standard limb electrode placement used to form the basic ECG leads in Einthoven's Triangle.
What is right arm, left arm, and left leg?
*These three points form a triangle that helps the ECG measure the hearts electrical activity from different angles.
This threshold indicates the point at which involuntary muscle contractions occur, a reaction of the body to electrical current, known as the "can't let go" reaction.
What is 10 mA?
In this circuit component, the voltage leads the current.
What is an inductor?
This organ secretes insulin to regulate glucose levels and enzymes to help digest food.
What is the pancreas?
HIPAA
What is the Health Insurance Portability and Accountability Act?
This device measures strength and frequency of uterine contractions.
What is a tocodynamometer (TOCO)?
Under NFPA 99, these are the maximum allowable values for ground resistance between exposed conductive parts and the ground pin, and for chassis leakage current in medical equipment.
What are 0.5 ohms and 300 µA?
The decimal equivalent of the binary number 101.
What is 5?
*Think of binary as a place-value system like decimal—but instead of powers of 10, it uses powers of 2. Read from right to left.
The rightmost digit =
20 = 1
21 = 2
22 = 4
Now match each digit:
1 × 4 = 4
0 × 2 = 0
1 × 1 = 1
Add them up:
4 + 0 + 1 = 5
101 (binary) = 5 (decimal
These small triangular-shaped endocrine glands located on top of each kidney produce hormones like adrenaline and cortisol.
What are the adrenal glands?
CMS
Centers for Medicare & Medicaid Services
*Federal agency oversees Medicare and Medicaid and sets healthcare reimbursement and quality standards.
