Automatic Ventilation Control

Introduction
This article describes the design of a portable automatic ventilation control system that also processes arterial oxygen saturation (SpO2) data from a pulse oximeter. The system, built around Freescale’s 8-bit MC9S08QG4 microcontroller (MCU), is designed to be a portable, automatic replacement for manual pulse oxygen and ventilation monitoring and control, requiring less human interaction during surgery. It can be particularly useful during surgery on infants. Overview All tissue ....etc

Heat Recovery Ventilation

Introduction


Heat recovery ventilation, also known as HRV, mechanical ventilation heat recovery, or MVHR, is an energy recovery ventilation system using equipment known as a heat recovery ventilator, heat exchanger, air exchanger, or air-to-air heat exchanger which employs a counter-flow heat exchanger (countercurrent heat exchange) between the inbound and outbound air flow.
HRV provides fresh air and improved climate control, while also saving e ....etc

At the onset of constant-load exercise in healthy humans, the rate of muscle metabolism increases to a steady state. However, when exercise is preceded by a bout of high-intensity or 'heavy exercise' several minutes prior, steady state is typically achieved more quickly. The aim of the present study was to study the metabolic effects of prior heavy exercise on a progressive exercise protocol, in which steady state is not achieved.

Abstract
An alternative method of distributing RF in buildings is proposed in which the heating and ventilation ducts are used as waveguides. Because of the relatively low waveguide loss, this method may lead to more efficient RF distribution than possible with radiation through walls or the use of leaky coax. Further, the use of existing infrastructure could lead to a lower-cost system. Initial experimental results are p ....etc

VENTILATION IN BUILDINGS
What is Ventilation ?
The process of removing used air by fresh air from buildings and spaces is called ventilation. This is done by Natural or Artificial methods
Effects of Ventilation :- 
1. To remove the used air from spaces/buildings.
To supply oxygen for humans.
Remove excessive moisture.
Remove excessive heat.
Cool the surroundings and freshen up the atmosphere in the building.
Composition of Air
Nitrogen 78%
Oxygen ....etc
