Estimation of arterial oxygen and carbon dioxide tensions by a single transcutaneous sensor
Abstract:
A transcutaneous electrochemical sensor designed to estimate arterial oxygen (Pao2) and carbon dioxide (Paco2) tensions simultaneously and continuously was evaluated in newborn infants with respiratory illnesses. After calibration with two dry gas mixtures the sensor gave estimates of Pao2 and Paco2 that were comparable with those obtained by two separate electrodes that are already established in clinical use.

Guidelines For Measuring Vital Signs
Before taking a patient's vital signs, a nurse would consider and assess the patient's comfort level and ensure appropriate equipment is available.
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Assessment of Diffusion and Perfusion
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...

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,...
