Objectives
Narrative objectives1
The aim of this study is to investigate the usefulness of delta VO2, which reflects the oxygen consumption of the lung itself, as an indicator of severity assessment, therapeutic response, and prognosis in severe respiratory disease.
* delta VO2 is defined as the difference between whole-body oxygen consumption (VO2 resp) obtained from an indirect calorimeter and oxygen consumption (VO2 fick) calculated from hemodynamic parameters using the reversed Fick equation.

Assessment
Primary outcomes
In this study, we mainly examine three items:
1) the relationship between mortality and delta VO2,
2) the relationship between delta VO2 and the P/F ratio
3) the relationship between changes in delta VO2 (delta-delta VO2) and changes in the P/F ratio (delta P/F).
Key secondary outcomes
# Relationship between delta VO2, ScvO2, and O2 extraction rate (O2ER)
# Relationship between delta VO2 and CRP
# Relationship between delta VO2 and days of mechanical ventilation, length of stay in ICU, reintubation rate, SBT success/failure rate, and RSBI
(SBT: Spontaneous breathing trial, RSRI: Rapid Shallow Breathing Index)

Key inclusion criteria
Forty-three adult patients who were intubated and mechanically ventilated in the ICU of our hospital for severe respiratory disease and who met all of the following criteria:
1) An arterial catheter is inserted
2) Oximetry CV catheter is inserted
Key exclusion criteria
Exclude patients and timings with any of the following:
1) Timing of using extracorporeal circulation
2) Patients with an arteriovenous shunt
3) Timing within 10 minutes after changing ventilator settings
4) Cardiogenic pulmonary edema is determined to be the main cause of worsening respiratory status, or patients undergoing blood gas analysis from a CV catheter to evaluate respiratory status.

Data are collected at the timing of clinical arterial blood gas analysis. Since it is expected that about 1 to 10 sets of data can be collected per patient, we expect to collect about 200 sets of data in total. We collect the following items:
# Patient information: age, sex, height, weight, body surface area, disease name, underlying physical conditions, SOFA score
# Ventilator settings: mode, FiO2, tidal volume, PEEP, maximum airway pressure
# Results of arterial blood gas analysis: pH, PaCO2, PaO2, SaO2, Lactate, Hb
# Vital signs, ScvO2 measured by Oximetry centarl venous catheter (Edwards Lifesciences, USA), CO measured by FloTrac (Edwards Lifesciences, USA) , VO2fick during arterial blood gas analysis
# VO2resp and delta VO2 obtained from indirect calorimeter (Q-NRG+, Nihon Kohden, Tokyo, Japan)
# If ventilator PB840 or PB980 is used, work of breathing
# If using an esophageal pressure balloon, transpulmonary pressure
Ventilation management follows the usual management policy: 1) FiO2 to avoid excessive hyperoxia and hypoxemia, 2) moderate PEEP (at least 5 cmH2O, referring to the PEEP table), 3) Tidal volume is set about 6-8 ml per kg of ideal body weight.
In addition, in this study, 1.58 is used as the coefficient for the amount of oxygen [mL] that binds to 1 g of hemoglobin used when calculating VO2 fick. Although 1.34 or 1.39 have been used so far, these are calculated values under standard conditions (0 degree Celsius, 1 atmospheric pressure) and may cause errors in actual living organisms. A factor of 1.58 (JA Clin Rep 2020;6:62) at 37 degrees Celsius is used in this study.
