MODIFICATION OF THE RESPIRATORY RESPONSE TO CARBON DIOXIDE BY SALICYLATE

The Respiratory Response to Carbon Dioxide

1. A technique for determining the respiratory response to carbon dioxide on the Peabody principle is described. 2. The relation between minute volume of total pulmonary ventilation and percentage of carbon dioxide in the inspired air can be expressed by a simple mathematical formula, viz. Y = K + ab(z), in which Y is the ventilation rate, X is the CO(2) content of the inspired air, and K, a, a...

Investigating the Relationship Between End Tidal Carbon Dioxide and Arterial Carbon Dioxide Pressure in Patients With Respiratory Distress Referred to the Emergency Room of Hazrat Rasool Akram Hospital

Background: Measuring End-Tidal Carbon Dioxide (ETCO-2) can be a non-invasive, fast, and reliable method to predict partial pressure of carbon dioxide (PaCO2) in patients with respiratory distress. This method, which can be a suitable substitute to measure PaCO2, is being used in many emergency rooms and operating rooms in developed countries, but its exact relationship with PaCO2 has not been ...

Idiopathic scoliosis. Mechanical properties of the respiratory system and the ventilatory response to carbon dioxide.

The aims were to examine the effects of scoliosis (angle), and age on lung volumes, elastic properties of the respiratory system, and the ventilatory response to CO2. The mean age of the 55 patients was 25.4 plus or minus SEM 2.5 yr, and the mean angle was 80 plus or minus SEM 4.2. The mean plus or minus SEM percent predicted lung volumes were vital capacity (VC), 60.5 plus or minus 2.7; total ...

A Numerical Model to Investigate Optimum Liquid Carbon Dioxide Seeding Rate in Weather Modification Projects

The respiratory response to carbon dioxide during Innovar-nitrous oxide anaesthesia in man.

In seven patients anaesthesia was induced by injection of a single dose of Innovar and maintained with nitrous oxide and oxygen. Marked respiratory depression persisted for longer than one hour. Tidal volume, respiratory rate and minute volume measurements were inadequate indicators of this effect which is well shown by measurement of end-tidal carbon dioxide tension. The best quantitation is t...
