Lesson 7.1
Equipment Safety and Readiness
Safe equipment use begins with inspection. Before using a device, verify that it is clean, intact, appropriate for the patient, powered correctly, and ready to perform as expected.
InspectCheck cords, plugs, sensors, cuffs, tubing, and surfaces
PrepareUse the correct accessories and settings
VerifyConfirm power, battery, self-test, and readiness
ProtectKeep patients and staff away from hazards
Remove From Service: Do not use equipment with exposed wires, damaged plugs, cracked housings, fluid intrusion, missing parts, failed self-tests, or unreliable readings.
Equipment-safety lesson completed.
Lesson 7.2
Stethoscopes and Blood Pressure Equipment
Stethoscopes, manual sphygmomanometers, and automated blood pressure monitors are common tools for patient assessment. Accuracy depends on correct cuff size, placement, patient position, and equipment condition.
Equipment
Key Safety or Accuracy Point
Stethoscope
Clean earpieces and diaphragm; inspect tubing for cracks.
Manual BP cuff
Use the correct cuff size and inspect the bladder and tubing.
Automated BP monitor
Use approved cuffs and verify the device completes its self-check.
Clinical Pearl: A cuff that is too small may produce a falsely high blood pressure reading; a cuff that is too large may produce a falsely low reading.
Blood-pressure equipment lesson completed.
Lesson 7.3
Thermometers and Pulse Oximeters
Thermometers and pulse oximeters provide quick measurements, but technique and patient factors can affect accuracy.
Thermometer Considerations
Select the approved route and probe cover.
Use the correct site and positioning.
Clean the device according to manufacturer instructions.
Consider recent eating, drinking, smoking, or activity when relevant.
Pulse Oximeter Considerations
Use a warm, still finger with good circulation.
Remove barriers such as heavy nail polish when policy requires.
Confirm the sensor is positioned correctly.
Compare the reading with the patient's appearance and symptoms.
Clinical Scenario
A pulse oximeter displays 82%, but the patient is talking comfortably and the pulse waveform is weak and irregular.
Best response: Reposition the sensor, warm the hand, check another site if allowed, and promptly report persistent abnormal readings.
Thermometer and pulse-oximeter lesson completed.
Lesson 7.4
ECG Machines and Electrodes
ECG quality depends on patient preparation, correct lead placement, intact cables, fresh electrodes, and minimizing electrical and movement artifact.
ECG Preparation Checklist
Verify the patient and order.
Explain the procedure and provide privacy.
Prepare clean, dry skin.
Place electrodes at the correct anatomical locations.
Inspect lead wires and connectors.
Ask the patient to remain still and relaxed.
Review the tracing for artifact before completion.
Artifact Reminder: Movement, loose electrodes, poor skin contact, electrical interference, and damaged cables can distort the tracing.
Equipment Concern: If a lead wire is damaged or the machine repeatedly fails self-testing, remove it from service and follow the reporting process.
ECG-equipment lesson completed.
Lesson 7.5
Centrifuges and Laboratory Equipment
Centrifuges separate specimen components by spinning at high speed. Improper loading can damage specimens, equipment, or nearby staff.
Safe Centrifuge Use
Inspect the rotor, tube holders, lid, and power cord.
Use compatible tubes and caps.
Balance tubes with equal volume opposite each other.
Close and lock the lid before starting.
Do not open the lid until the rotor stops completely.
Clean spills according to exposure-control policy.
Stop Immediately: Excessive vibration, unusual noise, burning odor, smoke, or a failed lid lock requires immediate shutdown and removal from service.
Centrifuge lesson completed.
Lesson 7.6
Autoclaves and Sterilization Systems
Autoclaves use pressurized steam to sterilize approved instruments. Proper loading, cycle selection, monitoring, drying, and storage are essential.
Step
Purpose
Cleaning before sterilization
Removes soil that can interfere with sterilization.
Correct packaging
Allows steam penetration and protects instruments afterward.
Chemical indicator
Shows the package was exposed to process conditions.
Biological monitoring
Provides evidence that the sterilization process can kill resistant organisms.
Dry storage
Protects package integrity after processing.
Do Not Use: Wet, torn, opened, punctured, or otherwise compromised sterile packages should not be used as sterile supplies.
Sterilization-equipment lesson completed.
Lesson 7.7
Cleaning, Disinfection, and Storage
Equipment cleaning must follow the device manufacturer's instructions and the facility's infection-prevention policies. The correct product, contact time, compatibility, and drying process matter.
CleanRemove visible soil
DisinfectUse an approved product and full contact time
DryPrevent moisture damage and contamination
StoreProtect from dust, damage, and unauthorized use
Compatibility Matters: Some chemicals damage plastics, sensors, screens, adhesives, or electronic components. Follow manufacturer instructions.
Cleaning and storage lesson completed.
Lesson 7.8
Troubleshooting, Documentation, and Escalation
Medical assistants may perform basic user-level checks, but should not attempt repairs beyond training and policy. Unsafe or unreliable devices should be removed from patient use.
Basic User-Level Checks
Confirm the power source or battery status.
Check that accessories are correctly connected.
Verify the correct setting or mode.
Repeat a self-test when permitted.
Replace approved disposable accessories if needed.
Compare the result with another approved method when directed.
