Technology at centre for critical care

At BLK Hospital, our comprehensive care for our patients goes beyond the diagnosis and treatment approaches. We aim to ensure that each and every patient under our care provided with the full continuum of emergency healthcare services. Our experts use latest and advanced technology comprises of offerings important for a faster and healthier recovery cycle.

Electrocardiography (ECG)

It is a more specific test to ascertain heart conditions and help doctors in deciding the treatment procedure for the patient. The doctor recommends this test if some inconsistency is seen in the patient’s chest X-ray and CT Scans. The procedure involves the injection of dye into the patient's heart through the blood vessels. The patient then lies down on a table which goes inside a tunnel-like machine known as MRI, which provides more clear images of the heart. 

Electroencephalogram (EEG)

It is a test performed to detect electrical activity in the patient’s brain using small metal discs (electrodes), which are attached to the scalp. The brain cells are active all the time even when the person is asleep. The doctor records this communicate between brain cells via electrical impulses as wavy lines on an EEG recording and evaluate the patient's condition accordingly.


Also termed as a cardiac echo or simply an echo is a sonogram of the heart, uses sound waves to produce images of the patient’s heart and help the doctor to see the patient’s heart beating and pumping blood. The doctor uses these images to identify heart diseases.


Ultrasound is used to generate pictures of the inside of the body using sound waves. It is a painless diagnostic technique that neither hurt the body nor involves the use of radiation. 


A Doppler ultrasound is a noninvasive test used to measure the flow of blood through your blood vessels. It involves the use of bouncing high-frequency sound waves (ultrasound) over the circulating red blood cells to diagnose many conditions like:

  • Blood Clots
  • Urinary Bladder Neck blood flow changes
  • Bulging Arteries (Aneurysms)
  • Peripheral Artery Disease
  • Carotid Artery Stenosis
  • Venous Insufficiency
  • Arterial Occlusion

Upper and lower GI endoscopy (to control bleeding) 

Upper and lower GI endoscopy is a procedure used to see the lining of your upper and lower GI tract for various diseases of the digestive system using a thin, flexible tube-like device known as an endoscope. The endoscope has a camera on its tip that shows the image of the GI tract on the monitor.

Video-assisted Flexible Bronchoscopy

It is Flexible bronchoscopy procedure that involves the use of an endoscope (bronchoscope) for TBLB/TBNA/Foreign body removal/ diagnostic and Therapeutic Interventions. The surgeon advances the bronchoscope with a camera on its top, through the airways in each lung to diagnose the problem. The camera displays the images from inside the lung on a video screen, using which a doctor can perform several other interventional pulmonology procedures.

Bronchoalveolar lavage

It involves the use of various instruments like Hot Forceps, Snare, Knife powered by cautery that passes through a bronchoscope in lung and is used for diagnosing and treating endobronchial (within the airways) obstructive lesions such as benign tumours, tracheobronchial stenosis, lung cancers, and subglottic stenosis.


It is a small electronic device that a doctor implants below a collar bone. It automatically monitors and regulates the heartbeats by transmitting electrical impulses, in order to stimulate the heart when it is beating too slowly.

Intra-Aortic Balloon Pump (IABP) 

It is a type of therapeutic device that helps the patient’s heart to pump more blood. A person with unstable heart needs this device to pump enough blood in the different parts of the body. The device consists of a catheter; one end of the catheter is attached to a balloon and the other end to a computer console. The doctor inserts the balloon inside the aorta of the patient and the console holds a mechanism for inflating and deflating the balloon when the patient’s heartbeat. It helps the heart to pump blood in different parts of the body. This is a temporary treatment and is used as an aid until the patient finds permanent treatment. 

Haemodiafiltration (HDF) 

A haemodiafiltration is a form of renal replacement therapy and is commonly known as a blood purification method. It works by utilising a convective-type driving force in combination with diffusional-type, which is a part of standard haemodialysis. 

In comparison to standard haemodialysis, HDF removes more middle-molecular-weight solutes. HDF tends to provide 

  • Improved clinical outcomes
  • Adequate convection volumes 
  • Increases the clearance of larger toxins

Continuous Renal Replacement Therapy (CRRT) 

CRRT is a slow and continuous extracorporeal blood purification therapy that is commonly used to treat critically ill patients with acute kidney injury. It is a dialysis treatment that provides renal support to patients who are hemodynamically unstable as a continuous 24 hour per day therapy.

CRRT helps by mimicking the functions of the kidneys. It purifies the blood by regulating water, electrolytes, and toxic products through the continuous slow removal of solutes and fluid. It is for the patients who meet criteria for haemodialysis therapy but cannot tolerate conventional intermittent haemodialysis (IHD) due to haemodynamic instability. 

Sustained Low-Efficiency Daily Dialysis (SLEDD)

SLEDD is an increasingly popular renal replacement therapy for the treatment of acute kidney illness. It is primarily for patients in the intensive care unit (ICU). It benefits the patient by providing good solute control and haemodynamic stability.

SLEDD has evolved as a conceptual and technical hybrid of Intermittent Haemodialysis (IHD) and Continuous Renal Replacement Therapy (CRRT). It holds a therapeutic aim that combines the desirable properties of each of these component modalities.

Computed Tomography Scan (CT or CAT Scan) 

This helps in creating an image of the different body parts with the help of contrast dye injected into one of your veins to make it easier to see the blood flow and spot aneurysms in your brain.

PET / CT Scan 

A PET/CT scan is one of the best ways to find different complications in the body. It uses radiation to show activity on a cellular level within the body. It provides nuclear imaging that uses a small amount of radioactive material to diagnose the severity of various kinds of diseases. BLK has installed the latest generation PET/CT Scan machine in order to aid the diagnosis and treatment of a plethora of diseases such as gastrointestinal, endocrine, neurological disorders, heart disease, and other abnormalities within the body. 

MRI (Magnetic Resonance Imaging)

BLK has installed the first of its kind a1.5 Tesla Volume MRI machine in India, which helps doctors to diagnose a problem and monitor it throughout the course of the treatment. It is a non-invasive and painless procedure that does not involve x-ray radiation to create detailed images of the organs and tissues within the body. It is utilised to image almost all body parts including the brain, spinal cord, breasts, heart, bones, joints, blood vessels, liver, prostate glands, etc.

Nuclear Imaging

It is an imaging technique that involves the use of small amounts of radioactive materials called radiotracers. These radiotracers are typically injected into the bloodstream, or either inhaled or swallowed by the patient. The radiotracer travels through the area under examination and gives off energy in the form of gamma rays. These rays are then detected by a special camera which is connected to a computer and create images of the inside of the patient’s body.

Non-Invasive Ventilation

Ventilation is used to support the respiration. It works by connecting a ventilator to an endotracheal tube that goes directly into the central airways from the mouth. It is a non-invasive way of delivering support to the patient by creating a positive pressure inside the airways, using a device like the BiPAP. 

  • BiPAP is a machine which comes with a motor that generates airflow at high pressure. The airflow is given to the patients through a face mask.
  • Continuous Positive Airway Pressure (CPAP) Therapy is the most common universally effective treatment for sleep apnoea. The process involves the use of a CPAP pump is used to prevent repetitive upper airway collapse. It applies a continuous flow of air to the airway and creates an air cushion in the throat in order to ensure normal respiration.

Invasive Ventilation 

Invasive mechanical ventilation is a device used to assist the patient with respiratory and breathing difficulties. It can become a lifesaving intervention during acute respiratory failure, weaning and for chronic respiratory failure when the non-invasive ventilator is not able to manage the patient’s condition. The ventilation can also be used during a surgical procedure in the ICU to maintain the patient’s airway. Some of the different types of invasive ventilators involve:

  • Recruitment Maneuvers 
  • Prone Ventilation
  • Airway pressure release ventilation (APRV)
  • Extra Corporeal Membrane Oxygenation 
  • Co2 removal
