Breathing period has several meanings depending on the context. Let's explore them:
1. Breathing Period in Physiology:
In the physiological context, a breathing period refers to the cycle of inhalation and exhalation. This can be further broken down:
-
Normal Breathing: A typical breathing cycle consists of a period of inhalation followed by a period of exhalation. The length of each phase can vary depending on activity level, health, and other factors.
-
Periodic Breathing: This refers to an abnormal breathing pattern characterized by cycles of apnea (cessation of breathing) and hyperpnea (increased breathing). The definition of periodic breathing is: "the presence of at least three consecutive apneas of at least 3 s each, separated by intervals no longer than 20 s."
2. Breathing Period in Programs and Schemes:
In certain programs and schemes, "breathing period" or "breathing space" refers to a temporary period of respite or relief. This might be:
-
Debt Respite Scheme (Breathing Space): A UK government scheme that provides a temporary pause on debt collection for individuals facing financial difficulties. "[The debt adviser] must not already have a breathing space or have had a standard breathing space in the last 12 months at the time they apply."
-
Program Application Periods: Some programs, like the LA County's Guaranteed Income Program ("Breathe"), have defined application periods. "The application period is now closed."
3. Breathing Period in Therapeutic Techniques:
Specific breathing techniques may incorporate pauses or rest periods between inhalations and exhalations.
-
Active Cycle of Breathing Technique (ACBT): This method used in cystic fibrosis treatment combines different breathing techniques, likely including periods of rest or controlled breathing.
-
Diaphragmatic Breathing with Rest Periods: Studies indicate that including rest periods after exhalation in diaphragmatic breathing can improve heart rate variability. "The objective of the current study was to test whether the inclusion of a post-exhalation rest period was effective at increasing HRV..."
4. Breathing Period in the Context of Illness:
The term "breathing period" can also refer to the duration of an illness that affects breathing, like a respiratory virus. While not explicitly stated as "breathing period," the context suggests this usage:
- Respiratory Illness Duration: The length of time a person is contagious with a respiratory virus is related to their breathing and symptom period. "You are likely to be less contagious at this time, depending on factors like how long you were sick or how sick you were."
In summary, the meaning of "breathing period" depends heavily on the context. It can refer to the physiological cycle of breathing, a period of respite, a timeframe in a program or therapy, or the duration of a respiratory illness.
