The most common way to EQUALISE is to pinch your nose through the mask and blow gently.
Another way is to swallow, and then you can also wiggle your jaw side to side.

Who spoke of an iron curtain descending across Europe?
Winston Churchill
Spoke of an Iron Curtain descending across Europe?
Winston Churchill
When the idea that exchange rates and prices adjust to equalize the cost of living across international boundaries is called what?
purchasing power parity
What is the definition for osmosis?
# a physical chemistry,cell biology. ------------------------------ Movement of solvent through a semipermeable membrane so as to equalize the concentration of solute across the membrane.
What is pressure gradient?
It is a difference in pressure
The pressure difference across the lung wall is the?
transpulmonary pressure
Why is a resistor needed to discharge or charge a capacitor in an electric circuit?
A resistor may be used in series charging for current limiting, filtering, or as a signal isolater. Resistors across caps are to discharge them for your safety or equalize voltages across the caps in series filtering circuit.
What is the effect of hypertonic solution on rbc?
A blood cell immersed in a hypertonic solution will cause water to move out of the cell, thereby causing it to shrivel. Osmotic pressure is water's tendency to seek to equalize its own concentration across a semipermeable membrane (like the cell membrane of a blood cell). So in a hypertonic solution (relative to the solution inside the blood cell), there are less particles of water per particle of solute. This means the water concentration inside the blood cell is higher, and mother nature will have none of that. So water will move out of the cell, seeking to equalize its concentration across the cell membrane. If the membrane is also permeable to solutes in the hypotonic solution, they will move across the membrane following their own chemical and electromagnetic concentration gradients.
What is the change in pressure measured across a given distance called?
Pressure gradient A+LS
How is sodium balance ECF volume and blood pressure are jointly regulated?
for blood to flow through a vessel or across a heart valve, there must be a force propelling the blood. This force is the difference in blood pressure (i.e., pressure gradient) across the vessel length or across the valve.
A solutions osmotic pressure differs from its hydrostatic pressure in that osmotic pressure is the force which pulls water across a membrane resulting from?
osmotic pressure is not the pressure which pulls the water , it is the other way round. It is the pressure with which the water molecule travel across the semi-permeable membrane. Hydrostatic pressure as the name suggests is the pressure due to the "standing column of water and not due to the movement
What determines the pressure on the low pressure side of the system?
temp of inbound air across a coil
