An automatic ventilator adjusting system has a three-way inline adapter coupled to 1) a breath sample line, 2) a ventilator (either invasive or non-invasive), and 3) a patient. The breath sample line is coupled to a Gas Exchange Monitor (GEM) and preferably has a female Luer lock end. Ventilator settings can be automatically set and/or adjusted using 1) an algorithm preferably having a feedback loop and 2) inputs including one or more of: gPaO2 TM (calculated arterial partial pressure of O2 by GEM), oxygen deficit, gPaCO2 TM (calculated arterial partial pressure of CO2), gPaCO2 TM /gPaO2 TM, PiO2-PETO2, TLC (Total Lung Capacity), FRC (Functional Residual Capacity), and Vd/Vt (deadspace ratio). Preferably, one or more of the inputs (e.g., gPaO2 TM,gPaCO2 TM, and oxygen deficit) are obtained non-invasively from a patients normal breathing gas samples as calculated by MediPines Gas Exchange Monitor (GEM). |
