Yes, you really do mostly breathe out of one nostril at a time: Have you ever noticed that one nostril always feels "stuffy" while the other seems to handle most of your breathing? This is due to a natural phenomenon called the "nasal cycle," a process where the dominant nostril alternates roughly every hour. During this cycle, the blood vessels in the nasal passages take turns constricting and dilating, causing one nostril to feel more open while the other becomes slightly congested. This automatic process, controlled by the autonomic nervous system, serves an important purpose. It allows the nasal passages to rest and rehydrate, maintaining optimal moisture and filtration of air. The typical nasal cycle lasts from 30 minutes to a few hours, ensuring both nostrils share the workload throughout the day. Though you might not always notice it, the nasal cycle is a key part of your body's respiratory efficiency.

Lung Volumes 🫁 Lung volumes refer to the different amounts of air that can be inhaled or exhaled during different phases of breathing. There are several different lung volumes that are commonly measured, including: Tidal volume: The amount of air that is inhaled or exhaled during a normal breath. Inspiratory reserve volume: The amount of air that can be forcefully inhaled beyond the tidal volume. Expiratory reserve volume: The amount of air that can be forcefully exhaled beyond the tidal volume. Residual volume: The amount of air that remains in the lungs after a maximal exhalation. Total lung capacity: The total amount of air that the lungs can hold, including both the tidal volume and all of the additional volumes.

Diaphragm Breathing and Lung Function https://lnkd.in/eTPCiVRg

How do we breathe ? Let's get to know the details🫁 Breathing involves two stages: 1- ⬆️inspiration during which atmospheric air is drawn in. 2- ⬇️expiration by which the alveolar air is released out. The movement of air into and out of the lungs is carried out by creating a pressure gradient between the lungs and the atmosphere. Inspiration can occur if the pressure within the lungs [ intra-pulmonary pressure ] is less than the atmospheric pressure, There is a negative pressure in the lungs with respect to atmospheric pressure. Similarly, expiration takes place when the intra-pulmonary pressure is higher than the atmospheric pressure. The diaphragm and a specialised set of muscles - external and internal intercostals between the ribs, help in generation of such gradients. Inspiration is initiated by the contraction of diaphragm which increases the volume of thoracic chamber in the antero-posterior axis. The contraction of external inter-costal muscles lifts up the ribs and the sternum causing an increase in the volume of the thoracic chamber. The overall increase in the thoracic volume causes a similar increase in pulmonary volume. An increase in pulmonary volume decreases the intra-pulmonary pressure to less than the atmospheric pressure which forces the air from outside to move into the lungs. Relaxation of the diaphragm and the [inter-costal muscles] Returns the diaphragm and sternum to their normal positions and reduce the thoracic volume and thereby the pulmonary volume. This leads to an increase in intra-pulmonary pressure to slightly above the atmospheric pressure causing the expulsion of air from the lungs. We have the ability to increase the strength of inspiration and expiration with the help of additional muscles in the abdomen. On an average, a healthy human breathes 12-20 or between 12-18 in some reference /minute. 🌟 The volume of air involved in breathing movements can be measured by using a spirometer which helps in clinical assessment of pulmonary function test [PFT]. #respiratory #RT #Respiratory_Therapy #Healthcare #respiratory_mechanism #breathing

𝙐𝙨𝙚 𝙔𝙤𝙪𝙧 𝘿𝙞𝙖𝙥𝙝𝙧𝙖𝙜𝙢: Focus on breathing deeply into your abdomen rather than shallowly into your chest. Place one hand on your chest and one on your abdomen; the hand on your abdomen should rise more than the one on your chest. 3.

𝘾𝙤𝙣𝙨𝙞𝙨𝙩𝙚𝙣𝙘𝙮: Practice deep breathing regularly, aiming for several minutes at a time, multiple times a day, to reap the full benefits.

Hyperventilation Simple Definition In layman’s terms, Hyperventilation can be described as excessive over-breathing. Over-breathing can occur from an increased rate or depth of breathing (or both together). This is how a person may describe another who is hyperventilating, or starting to hyperventilate: panting – rapid shallow breathing – gulping – choking – constant deep breathing – hiccupping. It can be distressing to see someone gasping for air, so an observer may not be able to use such precise adjectives! Some of the other symptoms described below (Signs and Symptoms) may also be visible to an observer but, without a visible or audible connection to excessive breathing, an observer may not connect them as anything to do with hyperventilation. Awareness It is possible to become familiar with some of the early onset symptoms of Hyperventilation by voluntarily breathing several deeps breaths at an accelerated rate. It is important to consult a doctor/medic before attempting this. If you are permitted to conduct this exercise, then certain precautions should be taken for your own safety. Never conduct this exercise by yourself – have someone monitor you. Never conduct this whilst working, driving, operating any machinery or when flying! Sit down before you start and ensure that you won’t fall. As soon as you have experience several mild symptoms, return to your normal rate of breathing. Only stand up when you are certain that all symptoms of dizziness and muscle weakness have dissipated. Becoming familiar with the early warnings that your own body experiences can reduce the chance of you missing the symptoms should they occur in-flight.

What is Coherent Breathing? This is a rhythmic and cyclical breath practice that is intended to synchronize cardiovascular and respiratory function (sometimes referred to as respiratory sinus arrhythmia or RSA). This type of breath practice can be very effective in regulating your nervous system and improving heart rate variability (HRV)...when done properly. MOST people can achieve coherent breathing at a rate of 6 breaths per minute, which is what the instructions below dictate. HOWEVER, the exact rate can vary slightly person to person. I use the physiological data I collect during sessions to determine the EXACT rate at which YOU achieve coherence to improve the efficiency of this exercise. Happy breathing!

Understanding Normal Lung Volumes 💡🌬️ Did you know? Our tidal volume (Vt) is the amount of air we inhale with each breath. Here’s what you need to know: 👨⚕️ For males, a typical tidal volume is around 500ml, while for females, it’s approximately 400ml. This calculation is based on 7ml per kilo of body mass. During resting breathing, each breath should: 🔄 Be rhythmical and consistent. 📏 Be of an appropriate volume for your body. ⏳ Maintain an inspiratory:expiratory ratio of 1:2. ⏸️ Include a brief pause at the end of expiration. Being aware of the intricacies of optimal breathing makes it easier to recognise poor patterns.
