Inspiration happens when the pressure inside the lungs is lower than the atmospheric pressure (outside) and air rushes into the lungs. Expiration is when the air inside the lungs is higher than the atmospheric pressure and the air rushes out of the lungs. If the intrapleural pressure (pressure within the pleura of the lungs) isn't maintained then the pressure in the lungs can't differentiate between inspiration and expiration and so the lung collapses.
an elevated pulmonary wedge pressure indicate that the pressure in the left atrium is evevated .
when atmospheric pressure is greater than the pressure within the lungs, inspiration occur.
no higher the blood pressure
If the blood pressure is elevated by psychological stress, the theraputic interaction with an animal can reduce the blood pressure by reducing the stress that causes it to be elevated.
Meniere's disease is the labyrinth disorder with elevated endolymph pressure in the cochlea.
Atmospheric Pressure
Intrapleural pressure is most negative at the completion of inspiration.
Generally speaking, when a female takes the blood pressure of a male, the reading is elevated.
Having slightly elevated blood pressure isn't always a bad thing. It's when blood pressure is too high that it causes issues. There are many healthy people who have slightly higher blood pressure.
High blood pressure is defined as consistentently elevated blood pressure exceeding 140 over 90 mmHg -- a systolic pressure above 140 with a diastolic pressure above 90.YOur systolic is somewhat elevated,but not high enough to be overly concerned about.
For calculating the collapse pressure of a pipe, you first need to calculate the Hoop stress, which is given by :- Stress = Circumferencial Force/(radial thickness*axial length) If the stress crosses this value the pipe would collapse.
