[Bedside evaluation of hemodynamic and respiratory data with a programmable pocket calculator]

Area of Science:

• Critical Care Medicine
• Cardiopulmonary Physiology
• Medical Informatics

Context:

• Critically ill patients require continuous monitoring of hemodynamic and pulmonary artery catheterization data for effective treatment.
• Manual calculation of derived cardiorespiratory variables is time-consuming in intensive care units.
• Online computer monitoring systems are often prohibitively expensive for bedside use.

Purpose:

• To develop a user-friendly, bedside program for a handheld programmable calculator.
• To automate the calculation of standard hemodynamic, oxygen transport, and perfusion-related variables.
• To provide rapid derivation of oxygen saturation and intrapulmonary shunt, including temperature correction for blood gas data.

Summary:

• The program calculates key hemodynamic variables (cardiac output, pressures) and cardiorespiratory parameters from arterial and mixed venous blood gas data.
• It incorporates temperature correction for blood gas analysis and derives crucial metrics like oxygen saturation and intrapulmonary shunt.
• Designed for handheld programmable calculators, it offers a cost-effective and efficient bedside solution.

Impact:

• Facilitates timely and accurate clinical decision-making in intensive care settings.
• Reduces the workload associated with manual data computation for healthcare professionals.
• Improves the management of critically ill patients by providing readily accessible physiological data.
