Impaired oxygen delivery
WitrynaCutaneous diabetic wound healing is a complex process with three overlapping phases: inflammation, proliferation, and remodeling ().Immediately after the precipitating injury, impaired vasculature impedes oxygen delivery to the wound, creating a hypoxic environment around the wound (5–7).This hypoxia is exacerbated by the recruitment … Witrynaoxygen hemoglobin poorly, releases well, inhibited Loading of Oxygen at lungs The plateau region -blood goes through systemic capillaries, O2 unbinds from Hb and PO2 falls from 100 to 40 mmHg. Steep region -small decreases in tissue PO2 result in substantial unbinding of O2 from Hb.

Transtracheal oxygen therapy (TTOT) is a method of administering supplemental oxygen directly into the trachea (windpipe). As an alternative to the nasal cannula, it delivers up to six liters of oxygen per minute through a small, plastic tube called a catheter. TTOT is generally reserved for people who have …
