Pulse oximetry in preterm infants
1Department of Paediatrics and Neonatal Medicine Hammersmith Hospital, London.
Abstract:
One hundred and twenty five measurements of arterial oxygen saturation (Stcao2) obtained with a transcutaneous pulse oximeter were compared with direct arterial oxygen tension (Pao2) in 13 preterm infants with predominantly fetal haemoglobin. Stcao2 of 86-92% corresponded to Pao2 of 5-13 kPa. Stcao2 above 92%, however, was sometimes associated with Pao2 above 13 kPa.

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 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...

Respiratory Assessment: Purpose and Indications
Objectives and Importance:
The primary goal of respiratory assessment is to evaluate patients at early risk of clinical deterioration. Since respiratory distress often precedes other signs of declining health, breathing patterns and sounds become a...
