Using finger-toe pulse oximetry to assess arterial blood flow
1North Hampshire Primary Care Trust, Basingstoke.
Abstract:
National guidelines (RCN, 1998; Clinical Resource Efficiency Support Team, 1998; SIGN, 1998) suggest that an assessment of ankle brachial pressure index using Doppler ultrasound is necessary to assess arterial blood flow in patients with leg ulcers or healed ulcers. Robin Cooper describes a newer, more simple test of arterial blood flow using a pulse oximeter, and discusses the advantages and disadvantages of each method.

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 radial pulse
The radial pulse, located at the wrist, is often the preferred site for assessing peripheral pulse because of its accessibility and dependability. The process of determining the radial pulse involves several steps:
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...
