Neck extension assessment ... |
Place 1 finger on the patient’s chin and 1 finger on the occipital protuberance and extending the head maximally on the cervical spine. At full extension, if the chin remained lower than the level of the occipital protuberance, we considered extension to be limited. |
In the pressure-volume loop below, cardiac work is best represented by: the area of the curve the slope of the line from points C to D the distance of the line from points C to D the slope of a line from points A to D .. .. ... .... ... .... .... .... In the pressure-volume loop below, cardiac work is best represented by: the area of the curve Cardiac work is the product of pressure and volume and is linearly related to myocardial oxygen consumption. Cardiac work is best represented by the area of the curve of a pressure-volume loop.
