Yes, it's possible to be intubated without being hooked up to a ventilator, but it's not a common practice outside of very specific medical situations.

Intubation involves inserting a flexible tube called an endotracheal tube (ET tube) through the mouth or nose and into the trachea (windpipe). This is usually done to help someone breathe if they're unable to do so adequately on their own, often because of anesthesia during surgery or because of a medical emergency like respiratory failure.

While intubation itself is a critical step in managing a patient's airway, it's typically followed by connecting the end of the tube to a ventilator, which assists with breathing by delivering oxygen-rich air into the lungs and removing carbon dioxide.

However, there are rare cases where intubation might be done without immediately connecting the patient to a ventilator. For example:

1. Preparation for ventilation: Sometimes, intubation is done as a preparatory step before connecting the patient to a ventilator. This might be necessary if there's a delay in setting up the ventilator or if the medical team needs more time to stabilize the patient before initiating mechanical ventilation.

2. Airway protection: In certain situations, intubation may be performed solely to protect the patient's airway, such as in cases of severe facial trauma or to prevent aspiration of fluids or objects into the lungs. Once the airway is secured with the tube, the patient might receive oxygen through the tube without the need for mechanical ventilation.

3. Monitoring purposes: In intensive care units (ICUs) or operating rooms, patients may be intubated for monitoring purposes, such as during certain procedures or while under anesthesia. In these cases, the patient's breathing may be supported by spontaneous breathing trials or by manual ventilation (using a bag-valve-mask), rather than immediately connecting them to a ventilator.

It's important to note that while intubation without mechanical ventilation is possible, it's not ideal for prolonged periods. Without the support of a ventilator, the patient may struggle to maintain adequate oxygen levels and clear carbon dioxide from their lungs, which can lead to respiratory distress or failure if not managed carefully.

In most cases, the decision to intubate a patient and whether to connect them to a ventilator immediately depends on their underlying condition, the goals of treatment, and the expertise of the medical team managing their care.
