Mainstream CO

Description

The M3016A Measurement Server Extension has a mainstream carbon dioxide respiratory
gas measurement for the Monitor monitoring device. It is designed to be used with the
M3000A Measurement Server for adult, pediatric, or neonatal patients, in a hospital
environment and during patient transport in and outside hospitals by clinical users.
CO
alveolar air into pulmonary capillary blood and the elimination of carbon dioxide from
pulmonary capillary blood and its transfer into alveolar air.
CO
the patient's intubation system. CO
patient's overall respiratory status.
Blood Gas concepts important to this section are:
• Airway Respiration Rate (AwRR)—The number of inspirations and expirations per
minute.
• End Tidal CO
tion.
• Inspired Minimum CO
• Instantaneous CO
• Ventilation—The movement of air in and out of the lungs by inspiration and expiration.

Factors affecting accurate measurement of mainstream CO
• Correct cleaning of the windows on the airway adapter and the transducer.
• Correct placement of the transducer on the airway adapter.
• Temperature of the patient's breath.
• Amount of water vapour in the patient's breath.
• Barometric pressure at the site of measurement acquisition.
• Other gases, most notably N
The EtCO

Infrared light is absorbed by CO
concentration in the gas mixture. By using an infrared detector to measure the absorption, the
