A piece of foam with an open cell structure is introduced into the wound and a wound drain is placed with lateral perforations on top. The entire area is covered with a transparent adhesive membrane, which is firmly fixed to healthy skin around the wound margin. When the exposed end of the drain tube is connected to a vacuum source, fluid is withdrawn from the wound through the foam into a reservoir for later disposal.It is necessary to cover the wound bed with a soft polyvinyl alcohol foam sponge, a non-stick oil-emulsion dressing (for exame, Johnson and Johnson), a contact layer (such as Mepitel), a thin layer of amorphous hydrogel (can be Intrasite Gel), or a calcium alginate (such as Sorbsan) before application of the gray sponge. Avoid the use of Vaseline, which is too oily and can alter the adhesion of the VAC cloth.
Explanation:
In medicine, a condition is considered asymptomatic if the patient is a carrier of a disease or infection but does not experience symptoms. A condition can be asymptomatic if it does not present the noticeable symptoms with which it is normally associated. Asymptomatic infections are also called subclinical infections. Other conditions (such as mental illness) may be considered subclinical if they present some but not all of the symptoms required for a clinical diagnosis. The term clinically silent is also used.
Answer:
experiments can be designed and performed by anyone with a curious mind
Explanation:
baking soda and vinegar explosions are an experiment that doesnt require expensive equipment
always do more then one trial, like shooting a basketball, if you shoot once and miss, can you say that you will never make it? or if you make it, can you say that you will never miss?
variables are what you are testing, you have to eliminate as many as possible so they dont effect your experiment
if you have any questions, leave them in the coments and i will try to answer them, if this helped, pls give brainliest.
The fossil record, biogeography, comparative anatomy, comparative embryology, and molecular biology.
If you reflect f(x) = 2x about the y-axis, you get a graph g(x) = -2x.
