Q-NRG+: Advanced Indirect Calorimetry for Critical Care
June 22, 2026 Metabolic Testing Rahul Tathe

The Q-NRG+ is an advanced metabolic monitoring system specifically designed to provide accurate and reliable measurements of Resting Energy Expenditure (REE) through Indirect Calorimetry. By measuring actual oxygen consumption and carbon dioxide production, the system helps healthcare professionals determine precise nutritional requirements based on a patient's current metabolic condition.

Trusted by hospitals, intensive care units, clinical nutrition teams, and research institutions, the Q-NRG+ supports evidence-based nutrition therapy and helps clinicians deliver personalized care to critically ill patients.

What is Q-NRG+?

The Q-NRG+ is a state-of-the-art metabolic measurement device that uses Indirect Calorimetry to assess a patient's energy expenditure and metabolic status.

Unlike traditional calorie estimation methods, the system directly measures respiratory gas exchange, allowing healthcare professionals to determine actual calorie needs with greater accuracy.

The Q-NRG+ evaluates:

  • Oxygen Consumption (VO₂)
  • Carbon Dioxide Production (VCO₂)
  • Resting Energy Expenditure (REE)
  • Metabolic Efficiency
  • Nutritional Requirements

This real-time metabolic information supports more effective nutrition planning and critical care management.

Why Accurate Energy Expenditure Measurement Matters in Critical Care

Critically ill patients often experience metabolic rates that differ significantly from standard population averages. Factors such as inflammation, infection, organ dysfunction, medications, and mechanical ventilation can dramatically alter energy requirements.

Accurate Resting Energy Expenditure assessment helps clinicians:

  • Prevent overfeeding and underfeeding
  • Optimize nutrition support therapy
  • Improve recovery outcomes
  • Reduce metabolic complications
  • Support ventilator weaning
  • Enhance patient monitoring
  • Improve critical care management

Understanding actual energy needs allows healthcare teams to provide personalized nutritional interventions that support healing and recovery.

How Q-NRG+ Works

The Q-NRG+ utilizes advanced Indirect Calorimetry technology to measure respiratory gas exchange and calculate energy expenditure.

Assessment Process

  1. The patient breathes normally through the monitoring system.
  2. Oxygen consumption (VO₂) is measured.
  3. Carbon dioxide production (VCO₂) is analyzed.
  4. Energy expenditure calculations are generated.
  5. Comprehensive metabolic reports are provided.

The process is non-invasive, clinically efficient, and suitable for critically ill patients, including those receiving respiratory support.
