Updated 10 Nov 2023

Q1. Define Electrocardiograph and Electroencephalograph.

Ans.

Electrocardiograph measures electrical activity of the heart while Electroencephalograph measures electrical activity of the brain.

Electrocardiograph (ECG) is used to diagnose heart conditions by measuring the electrical activity of the heart.
Electroencephalograph (EEG) is used to diagnose brain conditions by measuring the electrical activity of the brain.
ECG and EEG both use electrodes attached to the skin to measure electrical activity.
ECG is commonly used to diagnose heart...read more

Ans.

Defibrillators can use either 3-lead or 12-lead ECGs depending on the model and intended use.

Biomedical Service Engineer Interview Questions and Answers for Freshers

Ans.

Biomedical equipments are devices used in healthcare settings to diagnose, monitor, and treat medical conditions.

Biomedical equipments are essential tools in hospitals, clinics, and research laboratories.
They include devices such as X-ray machines, ultrasound scanners, defibrillators, and infusion pumps.
These equipments help healthcare professionals in diagnosing diseases, monitoring patient vital signs, and delivering treatments.
They require regular maintenance, calibration,...read more

Ans.

Ultrasound (USG) is a useful tool in diagnosing cardiovascular conditions, but it also has limitations.

USG can provide detailed images of the heart and blood vessels, aiding in the diagnosis of conditions such as heart valve abnormalities or blood clots.
However, USG may not be able to accurately assess certain structures or functions of the heart, such as the coronary arteries or heart muscle.
USG is non-invasive and does not involve radiation, making it a safe imaging option ...read more

Are these interview questions helpful?

Ans.

A ventilator is a medical device that helps patients breathe by providing oxygen and removing carbon dioxide from their lungs.

Ventilators are commonly used in hospitals and other medical facilities to support patients with respiratory failure or difficulty breathing.
They work by delivering oxygen to the lungs and removing carbon dioxide from the body.
Ventilators can be invasive, meaning they require a tube to be inserted into the patient's airway, or non-invasive, meaning the...read more

Ans.

The time period for O2 sensor and flow sensor varies depending on the specific model and manufacturer.

The time period for calibration of O2 sensors is typically every 12-18 months.
Flow sensors may need to be calibrated or replaced every 6-12 months.
Regular maintenance and testing of both sensors is crucial for accurate readings and patient safety.

Ans.

VT stands for Tidal Volume at ventilator, which is the volume of air delivered to the patient during each breath.

VT is an important parameter in mechanical ventilation, as it determines the amount of air the patient receives with each breath.
It is usually measured in milliliters (ml) or liters (L).
The VT setting on a ventilator can be adjusted based on the patient's needs and condition.
Monitoring VT is crucial to ensure proper ventilation and prevent complications such as bar...read more
