ETCO2 Monitoring What is EtCO2 EtCO2 or End Tidal Carbon Dioxide is the partial pressure or the maximal concentration of Carbon Dioxide at the end of an exhaled breath‚ which is expressed as percentage of CO2 or mmHg. The normal values are 5% to 6% CO2‚ which is equivalent to 35-45 mmHg. The term ‘capnometry’ is used to refer the measurement and display of concentration of EtCO2. Another term associated with this parameter is ‘capnography’‚ which refers to the display of a calibrated and a visual

Three varied location were selected; A classroom‚ a busy street (Recto Ave.) and the university garden. Temperature‚ relative humidity‚ atmospheric pressure‚ precipitation and evaporation rates were tested in each place‚ all with three trials then its average. A laboratory thermometer‚ slingshot psychrometer‚ barometer‚ graduated container cups and aluminium pan/containers were used respectively

Martin | Bottle Rockets | Table of Contents This extended investigation serves to examine and evaluate the physical forces that affect the flight of a bottle rocket. This will be accomplished by altering the water levels and the level of air pressure (psi) within the rocket will be altered‚ and tested‚ to further understand the mechanics of bottle rockets. Introduction Rocket flight has long been at the forefront of the human race’s exploration of our universe. This undeniable fact makes it

On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas
