minor bug-fixes

Rounding issues fixed. All calculations are accurate with one decimal position.  in the Calculator the used Thresholds / Study-parameters are listed in the header. Home view: Basic-Data Button renamed to Patient/Basic Data, as the process starts here :-)

New Logo. Access to Base Data now on main Screen.

Here is a short summary of the most important recent changes: Fick Calculation Overhaul: Replaced all VO₂ estimations (Dehmer, Bergstra) with new, complex regression formulas based on height, weight, age, and sex. The calculation for oxygen content now also includes a detailed formula for dissolved O₂. Dual BSA Logic: The app now uses two different BSA formulas: Mosteller: Used for general display and for calculating the Cardiac Index (CI) from Thermodilution. Du Bois: Used only for calculating the Cardiac Index (CI) from a Fick CO. Data Persistence (Save/Load/Share): Implemented a system to save and load complete patient datasets (including all stages and thresholds) using the Patient Identifier. The "Load Patient" list now allows for deleting patient files. Added a "Share Patient" function (via context menu) to export the raw patient .json file using the native Share Sheet. Calculation & Display Logic: All BSA values (Mosteller and Du Bois) are now rounded to one decimal place before being used in any subsequent CI calculations. The print layout (PrintView) was updated to a single-column view, with "Vitals" always appearing first for each stage. Bug Fixes: Resolved critical compiler errors (like "Cannot find type..." and "Invalid redeclaration") by refactoring data models (StageData, ThresholdSet) into a new SharedDataModels.swift file to break circular dependencies.

What's New This update introduces several enhancements and new features based on user feedback: Enhanced Data Entry: Added input fields for SBP, DBP, HR, and SpO2 to each stage under a new "Vitals" section. Introduced separate Heart Rate fields: one in 'Vitals' (general HR for the stage) and one specific to the Fick calculation ('HR Fick'). Base Data: Added unit selection (kg/lb, cm/in) for Weight and Height. BSA calculation now correctly handles selected units. Base Data: Added a timestamp button for "Patient on Table". Timestamps for RAP, PAS, and PCWP are now displayed inline next to the parameter label using "@ HH:mm" format. Improved Stage Functionality: Legs Up: Added a 5-minute countdown timer with Start/Pause/Reset controls. Legs Up: Enabled the "Large V-Waves" option for this stage. Legs Up: The "Derived" calculation section is now hidden for this stage. Exercise: Completely redesigned the timer section: Input for Watt load is now at the top. Features an advanced timer display: shows a 90-second countdown (red text) upon starting, then switches to a total elapsed time count-up (green text). Includes smaller Start, Stop, and "Up" buttons in a single row. "Start" and "Stop" set timestamps used to calculate the duration automatically. "Up" button restarts the 90-second red countdown phase while the total elapsed time continues. Start and Stop timestamps are displayed below the buttons. Reset is now a text link below the buttons. Refined Calculations & Display: Calculated pressures (mPAP, TPG, PCWP V-W) are now rounded to whole numbers. PCWP input field is visually disabled (greyed out, no threshold color) when "Large V-Waves" is active. The calculated "PCWP (V-W)" value now shows the threshold background color correctly. The label for calculated Cardiac Output now dynamically shows "CO (T)" for Thermodilution or "CO (F)" for Fick. Reporting Enhancements: Added Weight (with unit), Height (with unit), and "Patient on Table" time to the "Patient Data" section. Added a dedicated "Vitals" section (SBP, DBP, HR, SpO2) before "Pressures" for each stage in the report. Added a new "Gradients" section at the end of the report showing calculated "PCWP – RAP" for Rest and Exercise stages. Improved report layout with wider spacing between columns (Parameter, Value, Status) for better readability, optimized for A4 printing. The threshold status symbol for the standard PCWP value is now hidden in the report if "Large V-Waves" were used for that stage. New Reference Section: Added a new "Used Formulas" page accessible from the home screen, displaying all calculations used in the app in plain text format. We hope you find these updates helpful!

Print & Share: Generate a formatted PDF report with all measurements and results. Fick & Thermodilution: Flexibly choose between the Fick method and thermodilution for CO calculation. Exercise Timer: A new timer for the exercise phase with wattage input and automatic duration calculation. V-Wave Analysis: Option to calculate PCWP in the presence of large V-waves. Improved UI: A revised user interface for faster and more logical data entry.
