humidity measurement inside the helmet by a capacitative hygrometer and evaluation of patients' comfort
The medical gases are usually dry and cold thus when they are used during invasive mechanical ventilation they must be conditioned. No data are present on the necessity to condition the medical gases during non invasive mechanical ventilation. In this study the investigators studied the humidity and the temperature of the medical gases with and without any conditioning during non invasive mechanical ventilation in a group of healthy subjects and critically ill patients.
