The image shows Endotracheal Tube
- It describes the technique of passing a tube through the vocal cords.
- Severe hypoxemia requiring PEEP; hypercapnia with acidosis; inability to protect the airway; to control ventilation in the presence of raised intracranial (or intraocular) pressure; to facilitate certain diagnostic or therapeutic procedures; to allow administration of neuromuscular blockade.
- The correct position is with the lower part of the cervical spine flexed (by placing a pillow or other suitable pad under the patient’s occiput), and the atlanto-occipital joint extended(by tilting the head back) – the so-called “sniffing position”. This position aligns the axes of the mouth, pharynx, and trachea, and will give the best visualization of the cords during laryngoscopy.
- The vocal cords are then visualized with the aid of a laryngoscope, cricoid pressure by a trained assistant is applied and the endotracheal tube visualized passing through them.
- The position of the tube in the trachea can be confirmed in several ways, including observing increasing end-tidal carbon dioxide, aspiration, chest movement, and misting of the tube.
- A cuff is then usually inflated to provide a seal allowing positive pressure ventilation and to protect the airway from the aspiration of gastric contents or upper airway material.
