In inches do the inspiration numbers go up or down when measuring with cloth tape with forced expiration?
When measuring chest circumference with a cloth tape during forced expiration, the inspiration numbers typically go down. This is because forced expiration reduces the volume of air in the lungs, leading to a smaller chest circumference compared to inspiration, when the lungs are filled with air and the chest expands.

How many seven digit telephone numbers are possible if the first number is not allowed to be 0 or 1?
8,000,000 million telephone numbers are possible with these conditions, corresponding to the numbers 2,000,000 - 9,999,999. Many countries have forced dialing of the area code now, creating telephone numbers with a minimum of 10 digits. This means there are 8 million possible telephone numbers in each area code. (area code of 3 digits long).
What does forced into a corner mean?
Being forced to make an unpleasant or no win decision.
Is 38 percent bad in breathing test?
A result of 38 percent in a breathing test, such as a spirometry test measuring forced expiratory volume (FEV1) or forced vital capacity (FVC), typically indicates significantly reduced lung function. This could suggest severe respiratory issues, such as chronic obstructive pulmonary disease (COPD) or asthma. It is crucial to consult a healthcare provider for a proper evaluation and management plan based on the specific context of the test result.
What 5 consecutive numbers add up to 23?

What is the function of the obliquus externus?
The obliquus externus, or external oblique muscle, is a key muscle in the abdominal wall. Its primary functions include aiding in the rotation and lateral flexion of the trunk, as well as providing support for the abdominal organs. Additionally, it plays a role in movements such as bending and twisting, and it assists in the processes of forced expiration and stabilizing the pelvis during movement. The muscle also contributes to trunk flexion when acting bilaterally.
What is the difference between normal inspiration and expiration and forced inspiration and expiration?

Does the duration of inspiration or expiration vary during ERV or FVC?
Yes, the duration of inspiration or expiration can vary during forced vital capacity (FVC) and expiratory reserve volume (ERV) maneuvers. This variation is influenced by individual factors such as lung capacity, respiratory muscle strength, and airway resistance. In general, inspiration tends to take longer during FVC, while expiration tends to take longer during ERV.
What is the important muscle of inspiaration?
Most important muscle of inspiration is the diaphragm, which upon contraction, pulls the base of the lung down and increases the pressure inside of the lung, drawing air into the lungs. Other muscles that are not as important except for in forced inspiration are the intercostal muscles and sternocleidomastoid muscles, which only work when forced expiration is required as well :)
Does the diaphragm deal with inspiration or expiration?
The diaphragm primarily deals with inspiration. When the diaphragm contracts and moves downward, it creates more space in the chest cavity, allowing air to flow into the lungs. During expiration, the diaphragm relaxes and moves upward passively as the air is forced out of the lungs.
Which intercostal muscle help accomplish forced expiration?
internal
What is forced inspiration a sign of?
Forced inspiration can be a sign of experiencing creative block or burnout. It may indicate a lack of passion or motivation for the task at hand, leading to difficulty generating genuine creative ideas. It's important to find ways to rejuvenate and reconnect with your creativity to avoid forced inspiration.
The pectoralis minor and the sternocleidomastoid are useful in aiding forced expiration?
True
What does FVC designate?
The greatest volume of air that can be expelled when a person performs rapid, forced expiration.
When is the intrapleural pressure become positive?
Intrapleural pressure becomes positive during forced expiration or coughing when the muscles contract forcefully to increase the pressure within the thoracic cavity. This positive intrapleural pressure helps to push air out of the lungs.
What muscle is used in blowing?
The ab muscles are used for forcibly blowing air. A common misconception is that the diaphragm allows forced expiration when it is, in fact, used for inspiration. The diaphragm muscle will flatten (from its relaxed dome shape) when contracting allowing negative pressure to draw air into the lungs.
FVC and FEV1 measure what function?
Forced vital capacity (FVC) measures the total volume of air exhaled forcefully after a maximal inhalation. Within this total volume exhaled, the forced expiratory volume (FEV1) is measured during the 1st second of this manoeuvre.
What is the opposite of valsalva maneuver?
It's called a Muller maneuver and involves forced inspiration against a closed glottis.
