Preoxygenation works to prevent patients from desaturation while they’re under anesthesia. This technique extends the length of safe apnea, which is the time from cessation of breathing until the peripheral arterial oxygen saturation declines to 90% and continues to decline thereafter. 

Individuals who are at risk for oxygen desaturation are usually those with sleep apnea, morbid obesity, cardiac or pulmonary disease, anemia, pregnancy, or a predefined difficult airway. These patients usually can’t be ventilated or intubated during a procedure, which can create some additional challenges for clinicians to maintain oxygenation.  

Avoiding Insufficient Oxygenation

If a patient becomes insufficiently oxygenated, the consequences can be unequivocally severe. Arterial desaturation is incredibly dangerous, as it can cause brain and heart activity to become irreversibly compromised within a short period of time. The results can be permanent brain injury, cardiovascular complications, or death.

Preoxygenation prevents these events from occurring by filling the oxygen reserves in the alveolar, arterial, tissue and venous compartments, per Jonathan L. Benumof, M.D. via ASA Publications. To ensure a patient is actually fully preoxygenated, oxygen masks cannot have leaks or broken seals. This is the most important and vital aspect in maintaining full preoxygenation.

Adequate Versatile Oxygen Mask

This is completely preventable with the right oxygen masks. Oxygen delivery systems like the POM are specifically designed to maintain seals even when a variety of equipment is in simultaneous use. With modern innovations that have surpassed traditional oxygen masks, patients should never have to go into a procedure without full preoxygenation levels. 

Clinicians can also indicate that the system is completely sealed through the movement of the reservoir bag, along with normal capnography readings. The POM capnography port uses end tidal CO2 for Respiratory Rate Tending, allowing clinicians to monitor the seal and ventilation within the same contained system. 

The POM makes preoxygenation more efficient and reliable for clinicians, and therefore can better protect high-risk patients from desaturation than other traditional oxygen delivery systems. There is no reason to take the risk of pre oxygenating patients with masks that don’t seal correctly, and are not directly connected to the CO2 monitors that ensure that seal in the first place.
