What this Trial Is About

The primary objective of this prospective observational study is to evaluate the effectiveness of combining the Rapid Shallow Breathing Index (RSBI) and CRP-Albumin-Lymphocyte (CALLY) index to predict weaning success in adult patients within the intensive care unit. While weaning from mechanical ventilation is a critical clinical step, existing physiological metrics like RSBI do not fully capture a patient's inflammatory or nutritional status. This research introduces the CALLY index calculated as the ratio of the patient's immuno-nutritional reserve (Albumin and Lymphocytes) to systemic inflammation (CRP) as a complementary metabolic marker. By tracking approximately 105 participants at Basaksehir Cam and Sakura City Hospital, the study monitors weaning success over both a 48 hour and a 7 day period to identify both immediate and late phase extubation failures. The ultimate goal is to provide a more holistic prediction model that potentially reduces re-intubation rates and improves clinical outcomes by accurately identifying the optimal time for ventilator removal.

Eligibility Criteria

Eligible

You may qualify if you...

  • Patients aged 18 years and older
  • Patients who have received invasive mechanical ventilation for at least 24 hours in the general intensive care unit

  • Patients deemed ready for a Spontaneous Breathing Trial by the attending physician
Not Eligible

You will not qualify if you...

  • Patients under the age of 18
  • Patients with a known or detected pregnancy
  • Patients with a diagnosis of malignancy
  • Patients with neuromuscular diseases that could impair respiratory effort or muscle strength assessments, such as Myasthenia Gravis, Amyotrophic Lateral Sclerosis, or Guillain-Barré syndrome
