Randomly gasping can be a result of sucking in air or a result of heart and lung conditions, shortness of breath or anemia.
The automatic physiological reaction causing involuntarily gasps, is a reflexive sucking in of air in an attempt to rapidly increase oxygen intake into the lungs.
This increases the body's metabolic rate, building internal warmth in response to the cold.
Agonal gasps are involuntary and insufficient respirations that are caused by low oxygen in the blood, also known as hypoxia.
Silent breathing is a mode of breathing which occurs when one is at rest and does not require the cognitive thought of the individual breathing.
During silent breathing your diaphragm and external intercostals must contract.
A deep breath which is called diaphragmatic breathing, requires the diaphragm to contract.
When you breathe quietly, inhalation is active and exhalation is passive.
This means that during inhalation, muscles are contracting; these muscles are the diaphragm and the external intercostals.
Deliberately copying a relaxed breathing pattern seems to calm the nervous system that controls the body's involuntary functions.
Controlled breathing can cause physiological changes that include: lowered blood pressure and heart rate. reduced levels of stress hormones in the blood.
Eupnea is normal quiet breathing that requires contraction of the diaphragm and external intercostal muscles.
Diaphragmatic breathing requires contraction of the diaphragm and is also called deep breathing.
Costal breathing requires contraction of the intercostal muscles and is also called shallow breathing.
The normal sounds that people make when they breathe should hardly be noticeable.
However, abnormal breaths may sound strained, and odd noises may come from the lungs when the person inhales or exhales.
These sounds are more apparent with a stethoscope, but some are loud enough to hear with the ears.
When you are resting, your breathing should be quiet, gentle and regular.
People with a lung condition often change the way they breathe and their breathing can become noisy, irregular and fast.
The following exercise will teach you to relax and regulate your breathing.
This must be practiced on a regular basis.
