Abstract
We report the findings on 42 patients who underwent diagnostic and therapeutic interventional rigid bronchoscopy under SHFJV. Monitoring of the patients included ECG, blood pressure, SaO2, EtCO2, arterial blood gas analysis, FIO2 jet, FIO2 aw. SHFJV is defined as weight-based innovative mechanical ventilation combined with superposition of two jet-streams in an open system. The high-frequency jet-stream is responsible for the oxygenation; the normo-frequency jet-stream regulates the CO2. Basic patient characteristics (mean±SD): – Age 59.7±13.8 – FEV1 (liter) 2.79±0.58 – PaCO2 (mmHg) 35.52±6 Findings after 10 minutes SHFJV: – PaCO2 (mmHg) 35.13±11.78* – ETCO2 (mmHg) 27.48±4.81 – FIO2 (%) 64.76±12.95 *p=0,001 General characteristics of SHFJV: – No CO2 increase – No risk of barotrauma (open system conditions) – No air trapping (open system conditions) – Best ventilation in open system – Integrated gas analysis – Electronically controlled – Laser application without fire risk (laser safe mode) <b>Summary:</b> SHFJV in diagnostic and therapeutic rigid bronchoscopy is a safe and effective method of ventilation to achieve sufficient oxygenation without any increase of PaCO2.
