Cardio Shock vs MCSAID
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Cardio Shock
This medical app calculates CPO and PAPi to help assess patient candidacy for mechanical support. It utilizes formulas based on research from The Detroit Shock Initiative to provide these critical medical calculations.
- CPO calculation
- PAPi calculation
- Mechanical support assessment
- Based on Detroit Shock Initiative findings
- BSA and Fick formulas

Calculate CPO and PAPi to assess if patient is a candidate for mechanical support. The "recommendations" are based on the findings of The Detroit Shock Initiative: Basir MB, Schreiber T, Dixon S, Alaswad K, Patel K, Almany S, Khandelwal A, Hanson I, George A, Ashbrook M, Blank N, Abdelsalam M, Sareen N, Timmis SBH, O'Neill Md WW. Feasibility of early mechanical circulatory support in acute myocardial infarction complicated by cardiogenic shock: The Detroit cardiogenic shock initiative. Catheter Cardiovasc Interv. 2018 Feb 15;91(3):454-461. doi: 10.1002/ccd.27427. Epub 2017 Dec 20. PubMed PMID: 29266676. Disclaimer: Please note that this app does not replace clinical judgement. I can not take responsibility for the outcomes of the use of this app. There is no single standard formula for the calculation of BSA or cardiac output. Many authors recommend reducing peak oxygen consumption to 110mL O2/min for patients over the age of 75. This app uses the standard 125mL O2/min for all patients. Formulas: BSA is calculated as square root (heigh*weight)/36 Fick calculated as 125xBSA/ ((SAO2-SVO2) * hgb * 13.4. Finally: I have no relevant financial conflicts of interests or financial gains from use of this app. I'm just another idealistic general cardiology fellow looking to make a difference.

MCSAID

MCSAID is an educational application dedicated to the topic of mechanical cardiocirculatory support for patients with cardiogenic shock. A basic section introduces the definitions and classifications of cardiogenic shock as well as some of the common devices used for hemodynamic support in unstable patients. There is an algorithm for helping understand the decision process depending on key clinical variables such as cardiac output and PAPI. There are also several weaning and escalation algorithm. A calculator section is available for some common hemodynamic variables used in MCS decision-making and is available for quick-reference throughout the algorithm. MCSAID is an educational application for medical professionals and is not intended for making medical diagnoses. Medical decisions must be made by licensed professionals with the entire context of a patient’s medical history. If you are seeking a medical diagnosis, contact your physician and if you are experiencing a medical emergency, call your local emergency medical services.

Verdict
The clearest difference is update cadence: Cardio Shock at every 5 weeks against MCSAID's every 40 months. Cardio Shock also leads on iOS requirement (12.0 vs 15.0). On price, ads, in-app purchases and device support there is nothing between them.
