It is hypothesized that sildenafil will increase the release of oxygen from erythrocytes and shift the oxygen-hemoglobin curve to the right.Ellis, Shantol SastricePepple, Dagogo JohnThe journal of sexual medicineEllis SS,Pepple DJ.Sildenafil increases the p50and Shifts the oxygen-hemoglobin ...
A shift to the right is called the Bohr effect, producing an enhanced dissociation of oxygen from hemoglobin and improving delivery of oxygen to the tissues from the bloodstream. From: Orthopaedic Physical Therapy Secrets (Second Edition), 2006 ...

Thus a rightward shift in the O2 dissociation curve should theoretically increase O2 extraction and improve maximal O2 uptake (VO2 max). To test this hypothesis, we used the canine gastrocnemius muscle to study maximal exercise in eight dogs at a normal P50 (33.1 +/- 0.4 Torr) and with ...
assuming oxygen consumptionis relatively constant over time.9Inaccurate assessment of hemoglobin content will also lead to measurement errors, and simultaneous measurement of hemoglobin concentration should be obtained if possible. If O2consumption is accurately measured, the Fick method is more accurate tha...

The constant 10 (dl/l) converts l to dl, and 1.34 (ml O2/g) converts hemoglobin content to oxygen content. The following assumptions are used in the O2 calculation: SPVO2 = 0.97 (dimensionless), CVO2 = 185 ml O2/min/m2, BSA = 0.20 m2 and Hb = 16.0 g/dl [9, 13]. Results...

Analysis of oxygen transport function showed a leftward shift of the sigmoidal O-2-dissociation curve. P-50 was reduced to 15.5 mmHg. Investigation of family members revealed Hb York in the patient's sister, two daughters and a grandson. In retrospect, the mother of the patient may also ...
