| Description | Slide shows chart illustrating 'Curves of dissociation of the oxyhemoglobin at different pressures of oxygen.'
The 'x' axis is labelled 'Pressures of Oxygen'. The 'y' axis is labelled 'Percentages of saturation.'
There are five curves labelled from top to bottom: '5mm. CO2' '10' '20' '40' '80'.
Title below image reads 'Fig 13. - Curves of dissociation of the oxyhemoglobin at different pressures of oxygen. Five curves are shown to indicate that their dissociaton of the oxyhemoglobin is greatly influenced by the presence of CO2. The figures along the ordinates (10 to 100) indicate percentages of saturation of the haemoglobin, while the figures along the abscissa (0 to 160) indicate different pressures of oxygen. The curve marked "5mm. CO2" shows the amount of combination of oxygen and haemoglobin when the CO2 is absent or present only in traces. In this curve at a pressure of 30mm of oxygen it will be seen that the haemoglobin is 80 per cent saturated with oxygen, while with a pressure of 40mm. of CO2, which approximates that in the body, the haemoglobin at the same pressure of oxygen is only 50 per cent saturated.
