How is a sleep study test conducted, and what equipment is used?

In sleep study test in Delhi, Here’s an overview of how the test is conducted and the equipment used:

1. Preparation: As per Sleep study test in Delhi, Prior to the test, the individual may be asked to arrive at the sleep center in the evening. They will be given time to change into their sleepwear and prepare for the study. The sleep technician will explain the procedure and address any concerns or questions.
2. Electrode Placement: The individual undergoing the sleep study will have various sensors and electrodes attached to their body. These are painless and non-invasive. The sleep technician will measure and mark the appropriate locations for electrode placement.
3. Electrodes and Sensors: As per sleep study test in Delhi, the electrodes and sensors are then applied to specific areas of the body. The common placements include:

• Scalp: Electrodes are connected to the scalp to quantify brain activity (electroencephalogram or EEG). They are utilized to record the electrical signs created by the brain during various phases of rest.
• Face: Sensors are put close to the eyes to detect the eye movements, which then assist with identifying rapid eye movement (REM) sleep. This should be possible by utilizing electrooculography (EOG) or other eye-tracking devices.
• Chest and Abdomen: Belts or straps with sensors are wrapped around the chest and abdomen to monitor breathing patterns. They can detect chest wall movements, abdominal effort, and airflow, providing information on respiratory events.
• Limbs: Electrodes or sensors may be attached to the legs to measure muscle activity, particularly for detecting periodic limb movements or restless leg syndrome.
• Finger Probes: Small sensors or probes are sometimes placed on the fingers to monitor oxygen levels (pulse oximetry) during sleep.

1. Additional Monitoring: As per sleep study test in Delhi, depending on the suspected sleep disorder or specific requirements, additional equipment may be used. For instance:

• Microphone: A microphone may be positioned near the throat to pick up sounds related to snoring or abnormal breathing.
• EKG/ECG: Electrodes may be placed on the chest to record heart rate and heart rhythm (electrocardiogram or EKG/ECG).
• Nasal Cannula: A small tube may be inserted into the nostrils to measure airflow.
• Sleep Position Sensors: Specialized sensors can be placed on the body or mattress to detect changes in sleep positions.

1. Data Recording: Once all the electrodes and sensors are in place, they are connected to a polysomnography machine. This machine records the signals and data collected throughout the night. The equipment is designed to ensure minimal discomfort and interference with sleep.
2. Sleep Monitoring: During the sleep study, trained sleep technicians observe the individual’s sleep patterns and physiological parameters from an adjacent room. They monitor the recorded data, make notes of significant events, and ensure the proper functioning of the equipment.
3. Morning Evaluation: As per sleep study test in Delhi, in the morning, the sleep technician will remove the electrodes and sensors. The individual can then leave the sleep center, unless further daytime tests, such as multiple sleep latency test (MSLT) or maintenance of wakefulness test (MWT), are scheduled.

After the sleep study test in Delhi, the recorded data is analyzed and interpreted by sleep specialists, who evaluate the sleep architecture, breathing patterns, abnormal events, and other relevant factors to make a diagnosis and recommend appropriate treatment options.
