How to deliver Nasal Positive Pressure Oxygenation & allow free access to oropharynx
This video is from Dr Jim DuCanto, a good friend of PHARM and FOAMEd. It demonstrates the use of nasal oxygenation with positive pressure using an Oxylator device, whilst allowing free access to the oropharynx for the transoesophageal echocardiogram to be performed.
How could this be helpful? Well say you need to intubate someone who looks to be a difficult airway so you want to perform an awake intubation. Say this patient is needing CPAP or BiPAP via mask to maintain adequate oxygenation, right? Problem is when you remove the mask to intubate, even with spontaneous respirations, oxygenation starts to fail, right? You can try high flow nasal cannula but sometimes thats not enough. THe small nasal mask..or even a small paediatric face mask that will accomodate an adult nasal area allows you to connect up an Oxylator or ventilator and further enhance your ability to positive pressure oxygenate and even ventilate!
