Abstract
A measurement device and a method for monitoring a condition of a patient. The measurement device includes: a gas-guide apparatus, connected between an medical gas provider and a patient and configured to deliver medical gas from the medical gas provider to the patient; and at least one sensing apparatus, placed on an outer surface of the gas-guide apparatus and configured to detect real-time measurement data of the medical gas passing through the gas-guide apparatus. In this way, the at least one sensing apparatus is placed on the outer surface of the gas-guide apparatus, since the measurement data is a relative value which indicates a change of internal environment of the gas-guide apparatus, this can also avoid a problem of contamination compared with setting a sensor inside a respiratory device, thus improving the security of the measurement.
