Acute Respiratory Distress Syndrome, also referred to as ARDS, is when fluid builds in the lungs, bringing oxygen levels down to perilously low levels and making breathing intensely difficult and even life-threatening. Typically triggered by trauma or infections including pneumonia or sepsis, ARDS necessitates rapid, high-level care in an intensive care unit. With advances in critical care, treatments in the ICU for ARDS have become increasingly standardized with use of state-of-the-art monitoring, ventilation strategies, and a multi-disciplinary approach by Sugam Hospital to optimize outcomes in these patients.

ICU Understanding Of ARDS

ARDS develops rapidly, in most cases within hours to days, following a precipitate that causes an initiating or “knock-down” to the lung followed by the development of respiratory failure. This results in impaired oxygenation because fluid fills the alveoli, the tiny air sacs in the lungs that allow for the exchange of oxygen. In the intensive care unit  settings, management of ARDS involves strategies that have led to a philosophy based on limiting further lung injury and providing crucial support for oxygenation and ventilation. Since ARDS is a complex process, integration between teams of a given ICU is necessary. Teams consist of critical care specialists, pulmonologists, respiratory therapists, and nurses who collaborate in optimizing patient care with the real-time view of interventions.

Primary Therapeutic Avenues For ARDS Within The ICU

Mechanical Ventilation

The backbone of therapy for ARDS in the ICU setting continues to be mechanical ventilation. The mainstay is the achievement of low tidal volume ventilation that reduces the risk of ventilator-induced lung injury. This avoids the alveolar overdistension, which would amplify the injury to the lung. PEEP also helps in combating atelectasis; hence, the alveoli do not collapse during expiration and thereby enhance oxygenation because lung collapse is diminished. Oxygen levels are always checked by ICU teams, and therefore, ventilation settings are modified to ensure oxygenation without adding further lung damage.

Prone Positioning

Since patients undergoing prone positioning are placed on their abdomen, this has proved to significantly improve the oxygenation in ARDS patients. Such positioning favors better fluid distribution in lung regions and allows easier airflow through less damaged lung regions. Relevant studies’ observations indicated that there was a survival advantage with prone positioning. Such positioning is arduous and requires teamwork between the health professionals in the ICU because it is a process of constant change in positions with its hazards, such as pressure sores.

Fluid Management

The presence of ARDS often leads to fluid overload in the lungs, which further impairs oxygenation. ICU teams will adopt a much more conservative approach to fluid management, balancing hydration needs with the goal of avoiding fluid overload in the lungs. Diuretics may be used for fluid overload but are used judiciously to avoid undermining blood pressure and general circulatory competence. Management of fluids in ARDS is very important and generally needs regular adjustment according to the patient response.

Sedation And Neuromuscular Blockade

ARDS patients may need sedation to make them comfortable and allow them to be synchronized with the ventilators. In patients who have severe respiratory distress, neuromuscular blockers prevent muscle contractions and improve ventilation. Nonetheless, when used for a long time, they might lead to complications so that continuous monitoring is very necessary. ICU teams monitor sedation continuously, striving between the comfort of the patient and allowing gradual respiratory recovery.

Experimental Therapies

For severe cases that are opposite to conventional therapy, one may consider extracorporeal membrane oxygenation. ECMO is intended as an artificial lung, oxygenating the blood outside of the body so as to enable the lung to rest and heal. While not risk-free, ECMO has become a life-saving intervention for critical ARDS particularly when the conditions continue deteriorating despite interventions.

Optimal results from ARDS require an integrated multidisciplinary approach to treatment in the ICU. The patient is managed in the meticulous manner of a well-coordinated team of specialists, vigilant monitoring combined with individualized interventions that make the ICU setting singularly suited for managing this complex syndrome. Advanced therapies and round-the-clock care by the ICU teams make good contributions toward improving the survival rates in patients affected with ARDS; they are able to cross the critical period of ARDS and reach eventual recovery stages.
