Manual jet ventilator


The manual jet ventilator consists of five permanently assembled parts:

    1. Hose to connect to high-pressure (50 psi) oxygen supply with DISS connector (we keep an additional adapter for an Ohio quick-connect outlet attached to the device)
    2. Flow regulator
    3. Valve with lever
    4. Manometer
    5. Hose to connect to patient side with Luer lock adapter

Setting up the manual jet ventilator

We suggest the following sequence to set up and test the manual jet ventilator which is also described in the video below.

    1. Connect the manual jet ventilator to an oxygen source.
    2. Hold the hose which connects on the patient side close to the end at the Luer lock adapter.
    3. Open the flow regulator half to one turn only.
    4. Depress the lever to open the valve and check for airflow.
    5. Now open the flow regulator fully and depress the lever, again checking for airflow. This step ensures functionality of the flow regulator throughout the whole range of flows.
    6. Turn off the flow regulator and then open it again a half turn only.
    7. Temporarily occlude the distal opening of the hose which connects to the patient side at the Luer lock adapter. Depress the lever to open the valve and check for a pressure reading on the manometer of around 50 psi.
    8. You are ready to go!



The manual jet ventilator is mostly used for elective (manual) jet ventilation in the setting of laryngeal surgery.

The device is also used in airway emergency scenarios that demand a needle cricothyrotomy, which is discussed in the page on percutaneous cricothyrotomy.
