Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Both study instruments will be connected in parallel, a mandatory 10 minute period is then provided before commencement of gas exchange measurements to allow the Deltatrac mixing chamber to equilibrate with expired gas from the patient after the initial break in the ventilator circuit during connection. A simultaneous measurement with Deltatrac II and BEACON Caresystem will then be performed. Average values for energy expenditure (EE), VO2, VCO2, minute ventilation (MV) and respiratory quotient (RQ) will be registered after a 20 minute period. Measurements where the reference method registers a mean RQ of <0.6 or >1.2 will be discarded.

All aspects of the patient's ICU therapy are determined by the attending physician. Changes in ventilator settings, disconnection of the ventilator circuit or patient mobilization are to be avoided during and one hour previous to measurements unless deemed necessary by medical staff. In such event the ongoing measurement will be discontinued and restarted after a 15 minute resting period.

Patients can be measured on multiple occasions given a minimum interval of one calendar day.

Type of endpoint/s
Statistical methods / analysis
Limits of agreement and bias between VO2/VCO2 as measured by the study device (BEACON Caresystem) and reference method (Deltatrac II) will be compared using Bland-Altman plots. Agreement of energy expenditure values as measured by study device and the reference method will also be compared with the Bland-Altman method, although it is a dependent variable calculated from VO2 and VCO2. A sample size of 50 measurements in at least 20 patients is considered sufficient to determine limits of agreement within +/- 2.0 SD.

For descriptive statistics continuous variables will be analyzed for statistical significance using a two-tailed Student's t-test for paired samples and Wilcoxon signed-rank test as appropriate. An alpha level of =/<0.05 is considered significant.
