Exhaled Carbon Dioxide Monitoring Using Instantaneous CO₂ Mode During High-Frequency Oscillatory Ventilation in Very Low Birth Weight Infants.

ABSTRACT:

Background

High-frequency oscillatory ventilation (HFOV) presents challenges for noninvasive CO₂ monitoring due to its rapid oscillations. This study examines the feasibility of instantaneous CO₂ partial pressure (INST CO₂) monitoring during HFOV with a capnometer equipped with a mainstream CO₂ sensor.

Methods

This study included seven neonates receiving HFOV in the neonatal intensive care unit (NICU) at Shizuoka Children's Hospital. INST CO₂ values were recorded over 3- and 5-min intervals surrounding each blood gas sampling to determine the maximum INST CO₂ value (INST CO₂ MX). The primary outcome was the correlation between INST CO₂ MX and arterial partial pressure of carbon dioxide (P
