Muscle Mass and Blood Gases in ICU Patients

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this observational study, researchers will measure muscle mass in adult ICU patients using anthropometric techniques and compare it with arterial blood gas values, SpO2, heart rate, blood pressure, and urine output. The goal is to see if lower muscle mass is associated with poorer oxygenation and related physiological parameters. Data will come from patients in palliative care, pulmonary ICU, or cardiovascular ICU with at least 48 hours in the unit. The study discusses how muscle loss in critical illness can affect metabolism, respiratory strength, and recovery, and explores potential relationships with blood gas and oxygenation metrics.

Exclusion Criteria:

* Exclusion Criteria:

  * Patients with a history of previously diagnosed neuromuscular disorders (myasthenia gravis, Guillain-Barré syndrome, chronic polyneuropathies)
  * Patients with severe renal or hepatic insufficiency that could directly affect muscle mass
  * Presence of severe edema: Patients with a pitting edema score of 3+ or 4+ on the pitting edema test, or individuals with documented widespread edema in nursing or medical records
  * Patients with an amputation, hematoma, or open wound on the extremity to be measured
  * Pregnant patients
  * Patients whose intensive care stay lasted less than 48 hours or for whom the measurement could not be completed due to discharge or death
