Is P aeruginosa alpha hemolytic?
P. aeruginosa is not alpha hemolytic. Hemolysis is used mainly for the identification of Streptococci and can be used for Staphylococci. P. aeruginosa can be mistaken for being alpha hemolytic because it produces a green diffusable pigment. This pigment is especially visible if grown in media with little to no pH dye indicators such as SIM tubes, nutrient broths (undisturbed), API strips, etc. A good way to tell the difference between diffusable pigment production and hemolysis is to look at the agar surrounding isolated colonies. Diffusable pigments should be alot more visible in areas with higher concentrations of bacteria (quadrant 1) and may not be seen around isolated colonies of 24 hour cultures. Hemolysis should be readily seen around isolated colonies regardless of incubation time. If left long enough, P. aeruginosa will eventually clear all the RBC in the agar around the colonies (beta hemolysis).

How long do you keep a tourniquet on?
A tourniquet should not be removed at all. Tourniquets are a LAST RESORT method. They are hard to apply, they cause a lot of pain, and they can lead to the loss of any limb below wherever the tourniquet was applied. However, if the choice is your LIFE or your LIMB, choose the life. Apply the tourniquet and tighten it until the bleeding stops. Secure the stick to make sure the tourniquet does not loosen and DO NOT TOUCH IT. Get the victim to a hospital immediately. Once there, the doctors and nurses are trained in how to remove tourniquets and treat the wounds. If you leave a tourniquet on too long, the person might lose their arm/leg/whatever. If you take it off too soon, they can easily bleed to death.

How long should a tourniquet be left on a pt arm during venipuncture procedure?
how long should a tourniquet stay on a patients arm:There is no clearcut rule as to how long a tourniquet may be inflated safely, although various investigators have addressed effects of ischemia on muscle and nerve to define a relatively "safe" period of tourniquet hemostasis. In practice, safe tourniquet inflation time depends greatly on the patient's anatomy, age, physical status, and the vascular supply to the extremity. Unless instructed otherwise, report to the surgeon when 60 minutes of tourniquet time has elapsed. There is general agreement that for reasonably healthy adults, 90 minutes should not be exceeded without releasing the tourniquet for a short time.
What is the maximum leght of time for a tourniquet should be in place before blood is drawn?
