What does biphasic mean in medical terms?

Medical Definition of biphasic : having two phases a biphasic life cycle a biphasic immune response a biphasic stimulatory effect.

What is biphasic behavior?

Biphasic behavior: A behavior that has two distinct. phases. – Time-dependent biphasic behavior: As time evolves the output response initially increases but subse- quently decreases, even if the input is sustained.

What is meant by biphasic waveform?

An atypical 2-step—rather than single curve—pattern of clot formation, which is typical of disseminated intravascular coagulation (DIC), and detected by dynamic waveform analysis of changes in light transmission or absorption (LT/A), which occurs with coagulation.

What does monophasic mean?

Medical Definition of monophasic 1 : having a single phase specifically : relating to or being a record of a nerve impulse that is negative or positive but not both a monophasic action potential — compare diphasic sense b, polyphasic sense 1.

What is meant by biphasic insulin?

An insulin preparation that includes two components, typically a rapidly acting insulin, e.g., regular insulin, and an insulin that has a longer duration of action, e.g., NPH insulin.

What is a biphasic sleep pattern?

Biphasic sleep is a sleep pattern in which a person splits their sleep into two main segments per day. They may sleep longer at night, and then take a nap during the day. Or, they may split their nighttime sleep up into two segments. Biphasic sleep is also referred to as segmented or bimodal sleep.

Is biphasic sleep bad for you?

It could help you get more done in a day without compromising restfulness. For some, it may even improve wakefulness, alertness, and cognitive function. However, research is still lacking in this. Further, it’s observed in studies thus far that all people are different, and biphasic schedules may not work for everyone.

Are biphasic waveforms normal?

Due to the controversy surrounding the definition of biphasic, there is disagreement about whether biphasic flow is normal 2. Diastolic flow reversal is generally considered normal but pandiastolic forward flow is abnormal in the peripheral arteries 2.

What’s the difference between monophasic and biphasic?

A monophasic waveform delivers electrical shocks in a single direction from one electrode to another. With a biphasic shock, the current travels in two phases. In the first phase, the current runs from the first electrode to the second electrode via the patient’s heart.

What is a monophasic illness?

“A monophasic disorder means that there is just one occurrence of demyelination,” said Parrish, “while MS is characterized by recurrent demyelinating events.” Demyelination occurs when the body’s immune system attacks the myelin, the sheath that protects and insulates nerve fibers.

Why is biphasic better than monophasic?

Biphasic defibrillators are now the industry standard for a couple of reasons. First, they are smaller and lighter than monophasic defibrillators. Second, they have been shown to be more effective in mitigating skin burns and injury to the heart due, in part, to biphasic waveforms delivering significantly less current.

What’s the difference between biphasic and monophasic?

The key difference between monophasic and biphasic defibrillator is that the monophasic defibrillator is a type of defibrillation waveform where a shock is delivered to the heart from one vector as shown below. Whereas, in biphasic defibrillation, shock is delivered to the heart via two vectors .
