The sphygmomanometer ,commonly called a blood pressure cuff ,is an instrument used to obtain blood pressure readings by the ausculatory method.
It consists of an inflatable cuff with an attached pressure gauge .The cuff is placed around the arm and inflated to a pressure higher than systolic pressure(which occurs during pumping of the blood from the heart) to occlude circulation to the forearm .As cuff pressure is gradually released .The examiner listens with a stethoscope for characteristic sounds called the sounds of Korotkoff ,which indicate the resumption of blood flow into the forearm .The pressure at which the first soft tapping sounds can be detected is recorded as the systolic pressure .As the pressure is reduced further blood flow becomes more turbulent , and the sounds become louder .As the pressure is reduced still further , below the diastolic pressure, the artery is no longer compressed ; and blood flows freely and without turbulence.At this point ,the sounds of Korotkoff can no longer be detected .The pressure at which the sounds disappear is recorded as the diastolic pressure.

How can Henry's Law be applied to calculate the solubility of a gas in a liquid?
Henry's Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This means that as the pressure of the gas increases, the solubility of the gas in the liquid also increases. By knowing the partial pressure of the gas and the Henry's Law constant for that specific gas and liquid, one can calculate the solubility of the gas in the liquid.
How does the combined application of Avogadro's law and Boyle's law demonstrate proportionality in the relationship between volume and pressure in a gas system?
When Avogadro's law and Boyle's law are applied together, they show that the volume of a gas is inversely proportional to its pressure when the temperature and amount of gas are constant. This means that as the volume of a gas decreases, its pressure increases, and vice versa. This relationship demonstrates the proportionality between volume and pressure in a gas system.
What must remain constant for Boyle's law to be true?
1. A more correct name is Boyle-Mariotte law. 2. Only the temperature must remain constant.
How syringe applied to boyle's law?
Boyle's law applies to an ideal gas which is compressible P is proportional to 1/V the stuff people put in syringes is usually liquid which (compared to a gas) is virtually incompressible. Also a syringe has a hole in it which makes it rather useless as a compression chamber suited to the study of Boyle's law.
What best summarizes the ideal gas law?
PV=nRT
What gas law is applied in spraycan?
The ideal gas law is typically applied in a spray can. This law describes the relationship between pressure, volume, and temperature of a gas. When the propellant gas inside the spray can is compressed, it increases the pressure, allowing the contents to be released when the nozzle is pressed.
How do gas law applied on vacuum evaporator?
Gas laws are not directly applied in vacuum evaporation because the process occurs under reduced pressure, typically in a vacuum chamber. The decrease in pressure lowers the boiling point of the liquid being evaporated. This allows the substance to change from liquid to gas phase at a lower temperature without the need for specific gas law calculations.
What is the shape of graph of boyle's law?
boyles law is the status in which fixed amount of gas at given temperature and inversly proportional to applied pressure
What is the manipulated variable in Boyle's law?
The manipulated variable in Boyle's law is the pressure applied to the gas. Changing the pressure allows you to observe how the volume of the gas changes while keeping the temperature constant.

Are there any Real life example of ideal gas law?
The ideal gas law is commonly used in everyday situations, such as measuring the pressure of a car tire by using a pressure gauge. Weather forecasting also relies on the ideal gas law to understand how changes in temperature, pressure, and volume affect the atmosphere. Additionally, the ideal gas law is applied in scuba diving to calculate the changes in gas pressure underwater.
Why is the boyles law applicable only the idealgases?
Not true. It applies to real gases that are exhibiting ideal behavior. Any gas that is not 'close' to its boiling and is at a 'low' pressure will behave like an ideal gas and Boyle's Law can be applied. Remember there is no such thing as an ideal gas, so when Boyle did his experiments and came up with his law he was using a real gas, probably just air.
What is the difference between a sphygmomanometer and a blood pressure monitor?
I would love to take the opportunity to answer this question, The sphygmomanometer and BP meter are the same there is no difference.
What will happen if a gas held at a constant temperature has an increased in temperature applied to it?
boyle's law holds good in this case and the gas experiences decrease in volume....provided the gas is not in a container with fixed dimensions! its volume will decrease
What will happened if a gas held at a constant temperature has an increase in pressure applied to it?
boyle's law holds good in this case and the gas experiences decrease in volume....provided the gas is not in a container with fixed dimensions! its volume will decrease
What is the name of the device to monitor your blood pressure?
The real name for a blood pressure cuff is sphygmomanometer.
