Introduction to Cardiotocograph Machine

 
 

Cardiotocograph (CTG) machines are vital medical devices used in maternity care to monitor the foetal heartbeat and uterine contractions. Hospitals, clinics, and maternity centres across India rely on CTG machines to ensure maternal and foetal well-being during pregnancy and labour. Investing in a CTG machine helps improve diagnostic accuracy and patient safety. You can also explore financing options for medical equipment to manage costs effectively, and check your doctor loan eligibility to see if you qualify for easy financing.

What is a Cardiotocograph (CTG) machine?

A Cardiotocograph machine is a medical device used to monitor foetal heart rate and uterine contractions simultaneously. It provides graphical readings that help obstetricians assess the foetal condition and detect any abnormalities. CTG machines are widely used in antenatal care and during labour to ensure timely interventions if required.

Types of CTG machines

  • Standard CTG machine – Basic models for monitoring foetal heart rate and uterine contractions.
  • Portable CTG machine – Compact and battery-operated for use in small clinics or home visits.
  • Advanced CTG machine – Offers additional features such as digital data storage, touchscreens, and integration with hospital information systems.
  • Wireless CTG machine – Provides mobility for pregnant women while continuous monitoring is maintained.

How does a CTG machine work?

  • Foetal heart rate monitoring – Uses ultrasound sensors placed on the mother’s abdomen to detect heartbeat.
  • Uterine contraction monitoring – Measures contractions through a pressure-sensitive transducer.
  • Graphical display – Records heart rate and contraction data on paper or digital screens for interpretation.
  • Alarm systems – Alerts medical staff if abnormal readings are detected.
