Volume ejection fractions, derived from ventricular volumes, EF(V), are defined by the ratio of the difference of end-diastolic volume, EDV, and end-systolic volume, ESV, to EDV. In analogy, pressure ejection fraction, EF(P), may be defined by the ratio of the difference of systolic arterial pressure, SBP, and diastolic arterial pressure, DBP, to SBP.
Vaginal discharge with bacterial vaginosis will be gray, white or yellow. It will also have a fishy odor. If you have gonorrhea, you might have a cloudy or yellow discharge. Yeast infections can be apparent if you have a thick, white discharge. This discharge is often described as having a cottage cheese consistency.
BV and vaginal yeast infections are both common causes of vaginal discharge. They have similar symptoms, so it can be hard to know if you have BV or a yeast infection. Only your doctor or nurse can tell you for sure if you have BV. With BV, your discharge may be white or gray but may also have a fishy smell.
