What does biphasic mean in medication?
noun Pharmacology. a drug with two dosage levels over the period taken, as an oral contraceptive.
What does biphasic mean in biology?
Biphasic, meaning having two phases, may refer to: Phase (matter), in the physical sciences, a biphasic system, e.g. one involving liquid water and steam. Biphasic sleep, a nap or siesta in addition to the usual sleep episode at night. Phase (pharmacology) Biphasic disease.
What is meant by monophasic?
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 biphasic insulin?
Biphasic human insulins are mixtures of human neutral protamine Hagedorn (NPH) insulin and soluble human (Regular) insulin. The mealtime component of biphasic human insulins, soluble human insulin, has a delayed onset of action and prolonged duration.
What is a biphasic wave?
Biphasic Waveforms: A type of defibrillation waveform where a shock is delivered to the heart via two vectors. Biphasic waveforms were initially developed for use in implantable defibrillators and have since become the standard in external defibrillators.
What is alcohol biphasic effect?
High-dose alcohol has a biphasic effect on BP; it decreases BP up to 12 hours after consumption and increases BP > 13 hours after consumption. High-dose alcohol increases HR at all times up to 24 hours.
What does a biphasic response curve show?
A “biphasic” curve can be used to illustrate the expected dose response to light at a subcellular, cellular, tissue or clinical level.
What is biphasic and monophasic?
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 the difference between biphasic and monophasic defibrillators?
In monophasic shock, the shock is given in only one direction from one electrode to the other. In a biphasic shock, initial direction of shock is reversed by changing the polarity of the electrodes in the latter part of the shock. Usually the initial voltage applied is higher than the reversed polarity shock.
Are hospital defibrillators monophasic or biphasic?
Conventional defibrillators produce monophasic shocks where the current flows in one direction. Biphasic waveform technology developed from electrophysiological work on the design of implantable defibrillators.
Why is biphasic insulin used?
In order to make insulin therapy more acceptable to patients, newer formulations of insulin have been developed, such as biphasic insulins. Biphasic insulins conveniently provide both prandial and basal insulin in a single injection.
What is difference between biphasic and monophasic?
What does biphasic mean in Doppler?
biphasic: having two phases or variations having forward and reverse flow 5. systolic forward flow. either of the following (controversial): diastolic flow reversal without late diastolic forward flow (more common)
Is alcohol a biphasic drug?
Abstract. Background: Alcohol produces biphasic effects of both stimulation and sedation. Sensitivity to these effects may increase the risk for the development of alcoholism.
Why does my blood pressure drop when I drink wine?
The RAAS is controlled by the kidneys, and its function is to regulate blood pressure through three hormones: renin, angiotensin, and aldosterone. Alcohol increases blood levels of the hormone renin, which causes the blood vessels to constrict. This means that they get smaller in diameter.
Which drink has the most pure alcohol in it?

What does biphasic mean?
• Biphasic: two phases—one forward flow and one reverse component • Monophasic: single phase—forward flow with no reverse flow component • Other: waveform considered neither triphasic, biphasic, nor monophasic or a waveform that could not be categorized. The waveform presentation was exhibited to • Midwestern vascular sonography students
What does biphasic in V1 mean?
This produces a biphasic P wave with the initial positive deflection corresponding to right atrial activation and the subsequent negative deflection denoting left atrial activation This separation of right and left atrial electrical forces in lead V1 means that abnormalities affecting each individual atrial waveform can be discerned in this lead.
What is a biphasic birth control pill?
– Mircette. – Natazia. – Nordette. – Lo Ovral. – Ortho-Novum. – Ortho Tri-Cyclen. – Yaz. – Yasmin.
What are biphasic oral contraceptives?
– Monophasic birth control pills deliver the same amount of estrogen and progestin every day. – Biphasic birth control pills deliver the same amount of estrogen every day for the first 21 days of the cycle. – Triphasic birth control pills have constant or changing estrogen concentrations and varying progestin concentrations throughout the cycle.
