What is critical care?


Critical care is a medical discipline that includes diagnosing and treating various life-threatening injuries and diseases. It is usually provided in an intensive care unit (ICU), and a critical care specialist or an intensivist may be the primary care physician or consultant. 

These specialists must know about common critical disorders and the technological procedures and devices used in intensive care settings. They must be competent in complex ethical and social issues related to the care of critically ill patients, including end-of-life decisions, advance directives, prognosis estimation, and counseling patients and their families.

Most critical care physicians work in hospital intensive care units. They may have additional pulmonary or internal medicine training to better care for critically ill patients.


What are the different routes of training in critical care?


As mentioned above, critical care aspirants can undergo additional or subspecialty training in pulmonary and critical care medicine, which requires a three-year fellowship following medical school. After completion, they are eligible for subspecialty certification in both fields.

Other internal medicine physicians have various options for critical care medicine training. These consist of a fellowship in critical care medicine that requires two years of advanced training in internal medicine (including at least six months of critical care) after residency. Or physicians can opt for three years of training in cardiovascular or gastrointestinal subspecialties.

The American Board of Internal Medicine, American Board of Surgery, American Board of Pediatrics, and American Board of Anesthesiology jointly administer the certification of critical care medicine. 


Who requires critical care?


A person may require critical care if they are suffering from a fatal illness or injury, such as COVID-19, heart attack, heart failure, kidney failure, severe infections, shock, stroke, respiratory failure, and sepsis. They could also have severe burns, bleeding, or serious injuries due to a car crash, fall, or shooting. Lastly, people recovering from major surgeries, such as brain surgery, open heart surgery, coronary bypass surgery, or an organ transplant, may also need critical care. 


What equipment is present in a critical care unit?


In a critical care unit, healthcare providers use lots of different equipment, including:


  • Catheters, which are flexible tubes that either introduce fluids into the body or drain fluids out of it
  • Dialysis machines, also known as "artificial kidneys," to treat individuals with kidney failure
  • Feeding tubes to provide nutritional support
  • Intravenous (IV) tubes to administer fluids and medications
  • Devices that monitor your vital signs and display them on screens
  • Oxygen therapy, a remedy that provides additional oxygen for you to inhale
  • Tracheostomy tubes, which are breathing tubes inserted into a surgically made hole in the neck to reach the windpipe
  • Ventilators to help people with respiratory failure breathe by moving air in and out of their lungs


These machines can help save lives but may also increase infection risk. Critical patients may lack communication ability, so an advance directive is crucial. It assists healthcare providers and family members make end-of-life decisions if the patient cannot.


What are the fundamental differences between an ICU and a CCU?


The term CCU can refer to two different types of hospital units. Depending on the hospital, it can mean either a critical or cardiac care unit. ICUs and CCUs are similar in their focus on 24-hour patient care. However, not all hospitals with ICUs have dedicated cardiac care units. A cardiac care unit specializes in heart problems, while an ICU handles many life-threatening conditions. All three units use similar equipment and treatments for critical patients.


What is post-intensive care syndrome?


Post-intensive care syndrome (PICS) is a term used to describe a spectrum of physical, cognitive, and mental health problems that can take place after a person survives a fatal illness, particularly after being discharged from the ICU. People who spend time in a hospital's ICU are more likely to be affected. The risk increases with more extended stays and is higher for older people and those with prior health conditions. The ICU may worsen pre-existing conditions or lead to new issues, such as lung disease, muscle disorders, dementia, or acute brain dysfunction (from stroke or severe alcohol use disorder).

People who develop specific complications while sick are more likely to have post-intensive care syndrome. Complications can include severe infections, high or low blood glucose, hypoxemia, hypotension, sedation, acute respiratory distress syndrome, delirium, prolonged mechanical ventilation, multi-organ failure, exposure to systemic corticosteroids, and sepsis.

PICS can manifest differently in each person, with some experiencing just a few complications while others may suffer from many. Additionally, the severity of symptoms may vary and can affect mental health and physical and cognitive functions. 

These cognitive issues may include memory loss, difficulty thinking, poor attention and concentration, language issues, impaired visual-spatial abilities, and other brain-related problems. Physical functional issues may comprise pain, fatigue, neuromuscular weakness, shortness of breath, difficulty in mobility, poor lung function, sexual dysfunction, and other bodily discomforts. Mental health issues may include anxiety, irritability, depression, trouble sleeping, and post-traumatic stress disorder (PTSD), among others.
