His oxygen saturation is assessed continually to monitor for hypoxia. He is consistently between 90-92% at rest on 2 liters by nasal cannula. After breakfast Mr. Cohen complains of lower back pain that caused him to increased discomfort while ambulating to the bathroom.

There are several causes of anemia, but all forms lead to decreased oxygen transport throughout the body. Therefore, a low hemoglobin level, which was significantly identified in this study, implies a lower than average oxygen transportation throughout the body which has many negative implications.

Prior to blood gases, a 24-28% Venturi mask aiming for oxygen saturation of 88-92% is appropriate for patients with risk factors for hypercapnia but no prior history of respiratory acidosis. Occasionally, patients with normal PaCO2 , and no history or risk of hypercapnia, can initially elevate PaCO2 when given oxygen, though rarely to a ...
Oxygen Level Too Low? - Ask Dr. Weil
When oxygen saturation falls below 80%, cells do not receive enough oxygen to continue to function normally. At 30% oxygen saturation, cells are dying. Normally, oxygen binds with the hemoglobin (Hb) in red blood cells to form oxyhemoglobin (O 2 Hb).
