Assessment of Diffusion and Perfusion01:17

Assessment of Diffusion and Perfusion

989
Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.
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...

Pulse Oximetry01:24

Pulse Oximetry

340
Pulse oximetry, or SpO2, is a non-invasive method for continuously monitoring arterial oxygen saturation (SaO2). This procedure involves attaching a probe or sensor to the patient's fingertip, forehead, earlobe, or nose bridge. The sensor works by detecting changes in oxygen saturation levels through light signals generated by the oximeter and reflected by the pulsing blood under the probe.
Purpose
Average SpO2 values are greater than 95%. If the readings fall below 90%, it indicates that...

Area of Science:

  • Biomedical Engineering
  • Global Health
  • Anesthesiology

Background:

  • Capnography is crucial for patient monitoring in anesthesia and critical care.
  • Availability of capnography is limited in low- and middle-income countries (LMICs).
  • The Smile Train-Lifebox Capnography Project sought affordable solutions for LMICs.

Purpose of the Study:

  • To develop and evaluate a capnography device suitable for resource-poor settings.
  • To meet the specific needs of Smile Train partner hospitals for pediatric airway and cleft surgery monitoring.
  • To create accompanying educational materials for effective device implementation.

Main Methods:

  • A human-centered design approach was used, building on World Federation of Societies of Anaesthesiologists (WFSA) specifications.
  • Seven manufacturers submitted 13 devices; 3 were selected for rigorous testing.
  • Evaluation included build quality, clinical performance, and usability.

Main Results:

  • A combined capnography and pulse oximetry device by Zug Medical Systems was selected.
  • Educational materials were developed, piloted in Ethiopia, and refined.
  • The device and educational package are ready for distribution.

Conclusions:

  • A viable capnography solution has been developed for resource-constrained environments.
  • The project addresses a critical gap in patient monitoring in LMICs.
  • Future studies will assess the impact of capnography implementation in operating rooms.
