Inspired ventilation refers to a method of mechanical ventilation where air is delivered to a patient's lungs through a ventilator, typically during the inhalation phase of breathing. This technique is often used in critical care settings to support patients who are unable to breathe adequately on their own. Inspired ventilation can be delivered in various modes, allowing for controlled or assisted breaths based on the patient's needs. It ensures that oxygen is supplied effectively while removing carbon dioxide from the body.
Noninvasive ventilation provides respiratory support without the need for an artificial airway, typically through a mask or nasal prongs. In contrast, invasive ventilation requires the insertion of a tube into the airway, usually through the mouth or nose, to provide respiratory support. Noninvasive ventilation is often preferred when possible to reduce the risks associated with invasive ventilation.
Minute ventilation is the amount of oxygen inspired by the body in a minute. It is increased by long term exercise because over time the body becomes more adept at bringing more oxygen in to the lungs to be taken to the working muscles. As tidal volume and breathing rate increases the minute ventilation will increase as more breathes will be needed to be taken to meet the high demand for oxygen. A healthy young person will take around 35-45 breathes per minute where as an athlete may take around 60-70 breaths per minute.
To calculate alveolar ventilation rate, you need to multiply the tidal volume (the amount of air moved in and out of the lungs during normal breathing) by the respiratory rate (number of breaths per minute), and then subtract the dead space volume (the portion of inspired air that does not reach the alveoli). This gives you the amount of fresh air reaching the alveoli per minute.
Ventilation-controlled firea fire where the fire growth is determined by the amount of air available. A ventilation-controlled fire occurs when there is not enough air to burn all the materials being pyrolyzed.RAKESH KUMAR MEENA , rk_fire@hotmail.comfor fire related question plz contact me by email.thank u
Breathing is the process of taking air into and out of the lungs, while ventilation refers to the movement of air in and out of the lungs to facilitate gas exchange. Ventilation involves both breathing (inspiration and expiration) and the distribution of air within the lungs.

positive pressue ventilation is usually provided by a mechanical ventilator. A blend of oxygen and air coming out of the ventilator. The FiO2 is set on the ventilator. The person gets the FiO2 set on the ventilator.The manual positive pressure ventilation is by resuscitating with a self inflating bag usually provided with oxygen. FiO2 is fractional inspired oxygen and does not change with positive pressure ventilation or negative pressure ventilation. Manual bagging FiO2 may be changing according to supply of oxygen, inhalation (speed and volume) and frequency of bagging.

I opened all the window in my house to get some ventilation.
The ventilation rate of industrial ventilation should exceed the supply rate by 10%. There is a detailed description of these rates in the Lab Ventilation ACH Rates Standards and Guidelines manual.
