Department of Anesthesiology, Yokohama City University Hospital, 3-9 Fukuura Kanazawa, Yokohama, Kanagawa 236-0004, Japan.
Article Synopsis
- A critical "cannot-ventilate, cannot-intubate" situation emphasizes the need for effective airway management techniques like transtracheal jet ventilation (TTJV), which requires specialized equipment.
- This study aimed to compare the performance of TTJV using two devices: a manual jet ventilator (MJV) and an oxygen flush device from an anesthetic machine (AM), focusing on the impact of upper airway resistance (UAR).
- Results showed that while UAR affected the forward flow during TTJV with the MJV, the AM did not deliver an adequate flow, indicating that the devices respond differently to changes in UAR.

Article Synopsis
- - In emergency situations where intubation and oxygenation are not possible, the Ventrain(®) device is tested against the Manujet(®) for percutaneous transtracheal ventilation (PTV) in obstructed airways of anaesthetized sheep to assess their physiological performance.
- - Results showed that both devices achieved quick re-oxygenation, but the Ventrain managed lower peak airway pressures and better minute ventilation compared to the Manujet, without causing barotrauma.
- - The study suggests that the Ventrain is effective for stable oxygenation in critically obstructed airways, while the Manujet requires careful control to avoid complications; understanding these differences can guide the choice of ventilation method in

Department of Anesthesia, Nagoya City West Medical Center, 1-1-1 Hirate-cho, Kita-ku, Nagoya, 462-8508, Japan,
Article Synopsis
- The study explores the effectiveness of percutaneous transtracheal ventilation (PTV) in emergency situations where traditional ventilation fails, specifically by measuring tidal volumes (VTs) and airway pressure (Paw) using different catheter sizes.
- Researchers tested various catheter sizes (14G to 20G) in both high-flow oxygen and manual ventilation models simulating complete and incomplete airway obstruction, with specific flow rates and inspiratory/expiratory timing.
- Results indicated that larger catheter sizes resulted in higher tidal volumes during manual ventilation, while high-flow ventilation showed increased airway pressure but lower tidal volumes, likely due to a PEEP effect linked to the high flow rates.
