Abstract:
A couple of reports in literature have mentioned CO2 absorbers to be the cause for breathing circuit leak during anesthesia. Defective canister, failure to close the absorber chamber and overfilling of the chamber with sodalime were the problems in these reports. Among these, the last two are reports of human error resulting in problems. We report a case where despite taking precautions in this regard, we experienced a significant leak in the system due to a problem with the CO2 absorber, secondary to human error.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...

The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this principle...

Acute Respiratory Failure-I
Definition: It is defined by specific criteria based on blood gas measurements. Hypoxemia happens when the partial pressure of oxygen (PaO2) falls below 60 mmHg. At the same time,...
