Question

the nurse is caring for a client receiving oxygen therapy via nasal cannula. the client suddenly becomes cyanotic with a pulse oximetry reading of 91%. what is the next most appropriate action the nurse should take?

Answer 1

A low flow method that combines oxygen and ambient air is the nasal cannula. The range of flow rates provides 24% to 44% inspired oxygen at 1 to 6 liters/minute. Add humidification since rates over 4 litres per minute will dry up mucous membranes, which can hurt and bleed.

What should you do if your oxygen saturation is under 90%?

Any COVID-19 patient with an oxygen saturation below 90% should begin oxygen therapy, even if they exhibit no outward symptoms of low oxygen levels. Starting oxygen therapy right away is important if the patient exhibits any early indicators of low oxygen levels.

This is good since it explains why 90% saturation is typically regarded as adequate. A 60 PO2 typically corresponds well with a SpO2 and Sao2 of 90%. This is significant because it enables non-invasive pulse oximetry to detect your oxygen levels without the need for an intrusive blood sample.

The oxygen saturation of haemoglobin proteins, as measured by pulse oximetry, is termed.
