microstream capnography
Sidestream CO2 monitoring technology using low flow sampling rates specifically designed for pediatric patients with small tidal volumes.
Full Definition
Microstream capnography is a specialized form of sidestream capnometry that samples exhaled gases at very low flow rates (50 mL/min or less), making it particularly suitable for monitoring ventilation in infants and small children. Unlike mainstream capnography, this technology minimizes dead space and provides accurate CO2 readings even in patients with tidal volumes as low as 3-5 mL. The low sampling rate prevents dilution of exhaled gases and maintains circuit integrity in pediatric anesthesia systems.
Usage
Usage note: Hyphenate when used as a compound modifier before a noun.
In Context
- "The anesthesiologist connected microstream capnography to monitor the 2-kilogram neonate during the procedure." — Operating room documentation
- "Microstream technology was essential for accurate CO2 monitoring without compromising the low-flow anesthetic circuit." — Equipment selection rationale
