Understand where the blood is going and what the circulation depends on

A diagnosis tells you what the patient has. An operation tells you what was done. Understanding the circulation means connecting those facts with what you see at the bedside.

CLEAR CHD Physiology helps nurses caring for children with congenital heart disease build that understanding, whether you’re entering cardiac care or deepening your existing knowledge.

Your $19/month membership brings together:

  • The digital library: Explore foundational concepts, lesions, interventions, and bedside patterns.

  • Physiology maps and completed simulated examples: Organize what the circulation depends on and what an operation changes.

  • Clara, the CHD Physiology Coach: Ask for a direct explanation or practice your reasoning through guided questions.

  • Member resources: Access additional study tools and downloadable materials in the community.

Read a concept, explore a simulated example, and use Clara to work through what you understand and what remains unclear.

Created by a cardiac ICU nurse

I’m Sharon Welsh, a pediatric ICU and cardiac ICU nurse with extensive experience caring for children with congenital heart disease. I created CLEAR to help nurses connect anatomy, operations, and bedside findings through understandable physiology.

Your membership includes:

The CLEAR Digital Library

Access the full digital Library through Notion, including:

  • Foundations

  • Bridge Concepts

  • Lesions and Interventions

  • Bedside Prompts

  • Case Patterns

  • Study Guides

  • Edge Case Walkthroughs

See the sample library here

CHD Physiology Digital Library

The Library goes beyond diagnosis and operation names to explore what the circulation depends on and how changing relationships appear at the bedside.

Clara: two ways to explore the physiology

Sometimes you want a clear explanation. Sometimes you want to reason through a question yourself.

Clara supports both approaches. You can ask her to clarify a difficult concept directly, or work through a simulated scenario with questions that build the explanation step by step.

See how Clara helps you learn

These two free samples show what those conversations can look like:

  • Guided reasoning after tetralogy of Fallot repair: Follow a learner’s questions about right ventricular filling, CVP, and an intentionally maintained atrial communication.

  • Direct clarification about pulmonary atresia with intact ventricular septum: Explore why coronary dependence and right ventricular size are separate considerations.

Clara access is included with membership. The samples let you preview her approach before joining.

Clara is an education-only study tool. She does not provide patient-specific management advice or replace clinical judgment.

CLEAR Physiology Maps

The Pre-Return Physiology Map helps you organize what physiology entered the OR, what the operation changed, and what the returning circulation now depends on. Membership includes blank maps, instructions, and completed simulated examples.The maps can support orientation, independent review, preceptor-guided learning, and continued refinement of physiology reasoning.

Members receive access to blank maps, instructions for use, completed simulated examples, Clara-generated physiology syntheses, focused reasoning questions, and a growing collection of operation-based case sets.

Member Resources

Membership also includes additional educational resources, downloadable materials, free member tools, and new content added as the CLEAR learning system continues to grow.

Getting started

After payment, you’ll receive an email from Stan to activate your membership. Inside the community, you’ll find access to Clara and the member resources.

You’ll also receive a separate Notion invitation. Activate a free Notion account to access the digital library.

Cancellation and refunds

Membership costs $19/month and renews automatically. Cancel before your next billing date to stop future charges.

Monthly payments are generally nonrefundable, and partial-month refunds are not ordinarily provided.

If you experience a duplicate or incorrect charge, cannot access the included resources, or have an exceptional circumstance, contact snwelsh21@gmail.com. CLEAR CHD Physiology will review the issue and provide an appropriate resolution, which may include a refund.

This policy does not limit any refund rights required by applicable law.

Educational use only. CLEAR CHD Physiology resources do not replace operative handoff, patient-specific assessment, institutional practice, medical decision-making, or clinical judgment.

•       Free downloads, lead magnets, and other promotional materials.

Institutional and multi-user licensing. Any hospital, health system, school, or other institutional or multi-user license is offered only under a separate written license agreement. These Terms govern individual consumer purchases. Where a separate institutional license agreement exists, that agreement controls for the engagement it covers.

We reserve the right to modify, suspend, or discontinue any Product or Service at any time, with or without notice. Modifications to a study tool or platform are part of the ordinary course of business and do not constitute a basis for refund.

5. Pricing, Payment, and Taxes

All prices are stated in U.S. dollars unless otherwise noted. Payment is due in full at the time of purchase unless a written payment plan has been agreed in advance.

You authorize us, our payment processors (which may include Stan Store, Stripe, or any successor processor), to charge your selected payment method for the full purchase amount, including any applicable taxes and fees.

You are responsible for any sales, use, value-added, or similar taxes applicable to your jurisdiction. If we are required to collect such taxes, they will be added to the purchase price at checkout. Promotional codes, discounts, and bundle pricing are valid only as stated and may not be combined unless expressly permitted.

It is your responsibility to provide an accurate email address at checkout, check your spam, junk, and promotions folders, and contact our support team within seven (7) days if you have not received delivery confirmation.

Failure to receive a Product due to an incorrect email address, full inbox, spam filter, blocked sender, or other Customer-side issue does not constitute non-delivery on our part and is not a basis for refund or chargeback. Contact: snwelsh21@gmail.com.

7. All Sales Final: No Refunds

ALL SALES ARE FINAL. WE DO NOT OFFER REFUNDS, RETURNS, EXCHANGES, OR CREDITS FOR ANY PRODUCT OR SERVICE UNDER ANY CIRCUMSTANCES, INCLUDING BUT NOT LIMITED TO THE FOLLOWING:

•       Change of mind, dissatisfaction, or unmet expectations;

•       Failure to use, download, access, or complete the Product;

This no-refund policy is a material term of these Terms and a primary reason our Products are priced as they are. By completing your purchase, you expressly waive any right to a refund except as required by non-waivable applicable law.

Limited exception (Duplicate Purchases). If you can demonstrate that you were charged twice for the identical Product within seventy-two (72) hours due to a verifiable technical error, contact us at snwelsh21@gmail.com with proof of both transactions. We will, in our sole discretion, refund the duplicate charge. This is the sole exception to the no-refund policy.

Limited exception (Non-Waivable Statutory Rights). Nothing in this Section limits any non-waivable refund right granted to you under applicable consumer protection law in your jurisdiction. Where such rights exist, our liability is limited to the minimum required by that law.

8. Chargebacks, Disputes, and Mandatory Pre-Dispute Contact

Before initiating any chargeback, payment dispute, or reversal with your bank, card issuer, or payment processor, you agree to first contact us in good faith at snwelsh21@gmail.com and allow us at least fourteen (14) days to attempt to resolve the issue. Use the subject line “Dispute – [Your Order Number]” and include your name, the email used at purchase, the Product, the date of purchase, and a description of the issue.

Chargebacks Filed Without Pre-Dispute Contact. Initiating a chargeback, dispute, or reversal without first contacting us and allowing fourteen (14) days for resolution is a material breach of these Terms and constitutes wrongful or fraudulent dispute activity, particularly where the Product was delivered or made accessible to you, you accessed or used any portion of the Product, or you purchased with full notice of the All Sales Final policy.

Chargeback Administrative Fee. If you initiate a chargeback in breach of this Section, you agree to pay us, in addition to the original purchase price, an administrative fee of one hundred fifty U.S. dollars ($150.00) per chargeback to cover our processing costs, documentation labor, response preparation, and processor penalties. This fee is liquidated damages, not a penalty, and represents a reasonable estimate of our actual costs.

If you initiate a chargeback in breach of this Section, we reserve the right to contest the chargeback with full documentation (including delivery records, access logs, and your affirmative acceptance of these Terms at checkout); recover the original purchase amount, the administrative fee, processor fees, and reasonable attorneys’ fees and collection costs; refer the unpaid balance to a third-party collections agency; immediately and permanently revoke your access to all Products and Services with no refund; and block your email and payment instruments from future purchases. These remedies are cumulative and in addition to any other rights available to us at law or in equity.

9. License to Use Digital Products

Subject to your compliance with these Terms and full payment, we grant you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Products you purchased solely for your personal, individual educational and study use.

10. Restrictions on Use

You may not, and may not permit any third party to:

•       Resell, sublicense, rent, lease, share, distribute, or transfer any Product, in whole or in part;

•       Post, upload, mirror, or share Product files, content, or access links on any website, forum, drive, cloud folder, group chat, social media, or peer-to-peer service;

•       Use any Product as input or training data for any artificial intelligence model, machine learning system, large language model, or similar technology;

•       Reverse engineer, decompile, scrape, harvest, or extract content, prompts, system instructions, or methodology from any Product, including the Bot;

•       Remove, alter, or obscure any copyright, trademark, watermark, or other proprietary notice;

•       Use the Products to create a competing product, study tool, bot, curriculum, or service;

•       Share access links or credentials with anyone, including coworkers, classmates, family, or members of any study group;

•       Use the Products in any way that violates applicable law, infringes any third-party right, or breaches any platform terms (including Stan Store or OpenAI).

Violation of this Section is a material breach. We may immediately revoke your license and access without refund, in addition to any other remedies available to us.

11. The Bot: Additional Terms

In addition to these Terms, your use of the CLEAR Physiology Reasoning Bot or any custom GPT study tool is subject to the following:

•       The Bot is a study tool and learning tool. It is not a clinical decision-support system, not a diagnostic tool, and not a substitute for licensed clinical judgment, supervision, institutional protocols, faculty instruction, or professional medical or nursing practice;

•       Diagnostic tools;

•       Substitutes for licensed clinical judgment, supervision, faculty instruction, institutional protocols, or formal nursing or medical education;

•       Patient care tools;

•       Sources of medical, nursing, legal, financial, or other professional advice.

We make no guarantee, warranty, or promise regarding any specific outcome, including but not limited to passing any licensure or board examination; admission to any program; employment, promotion, or career advancement; clinical competence, performance, or evaluation outcomes; or any specific grade, score, or academic result.

Your results depend on many factors outside our control, including your effort, prior preparation, study habits, program rigor, and individual circumstances. Testimonials and case examples reflect the experiences of individual users and are not promises or representations of typical results.

You acknowledge that you remain solely responsible for your clinical practice, professional licensure, scope of practice, employer policies, and compliance with all applicable laws and standards of care.

13. User Submissions and Feedback

If you post, submit, or share any content (including questions, comments, feedback, testimonials, or written work) on our Services (“User Content”), you grant us a worldwide, royalty-free, perpetual, irrevocable, sublicensable, transferable license to use, reproduce, modify, adapt, publish, translate, distribute, display, and create derivative works of your User Content for any business purpose, including marketing, testimonials, and product improvement, in any media now known or later developed.

You represent and warrant that your User Content is your own original work or that you have all necessary rights to grant this license, and that it does not infringe any third-party right, violate any law, or contain protected health information (PHI) or other regulated data.

14. Third-Party Platforms

Our Products are delivered through and may depend on third-party platforms, including but not limited to Stan Store, OpenAI (ChatGPT), and Stripe. Your use of those platforms is subject to their own terms and privacy policies.

We are not responsible for outages, downtime, policy changes, account suspensions, data losses, or other actions of any third-party platform. We will use commercially reasonable efforts to maintain availability, but no service-level commitment is given or implied.

15. Intellectual Property and Trademarks

All Products, Services, content, frameworks, methods, branding, designs, prompts, system instructions, and derivative works (collectively, the “Company IP”) are owned by Sharon Welsh or our licensors and are protected by U.S. and international copyright, trademark, trade secret, and other intellectual property laws.

CLEAR CHD Physiology, the CLEAR Framework™, the CLEAR Physiology Reasoning Bot, and related marks, logos, and slogans are trademarks or common-law marks of Sharon Welsh. Nothing in these Terms grants you any right, title, or interest in or to the Company IP except the limited license expressly granted in Section 9. Unauthorized use is a material breach and may violate applicable copyright, trademark, and unfair competition laws.

Termination does not entitle you to a refund of any amounts paid.

Sections that by their nature should survive termination will survive, including Sections 7, 8, 9, 10, 12, 13, 15, and 18 through 24.

18. Disclaimer of Warranties

ALL PRODUCTS AND SERVICES ARE PROVIDED “AS IS” AND “AS AVAILABLE,” WITHOUT WARRANTY OF ANY KIND, EXPRESS, IMPLIED, OR STATUTORY, INCLUDING WITHOUT LIMITATION ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, ACCURACY, OR UNINTERRUPTED OR ERROR-FREE OPERATION.

We do not warrant that the Products or Services will meet your requirements, that any defect will be corrected, or that the Services will be uninterrupted, timely, secure, or error-free. Your use is at your sole risk.

19. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, IN NO EVENT WILL THE COMPANY, ITS OWNERS, OFFICERS, EMPLOYEES, CONTRACTORS, OR AFFILIATES BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR ANY LOSS OF PROFITS, REVENUE, DATA, GOODWILL, OR OPPORTUNITY, ARISING OUT OF OR RELATED TO THESE TERMS, ANY PRODUCT OR SERVICE, OR YOUR USE OF OR INABILITY TO USE ANY OF THE FOREGOING, WHETHER BASED IN CONTRACT, TORT, STRICT LIABILITY, OR ANY OTHER THEORY, EVEN IF WE HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

OUR TOTAL AGGREGATE LIABILITY FOR ANY CLAIM ARISING OUT OF OR RELATED TO THESE TERMS OR ANY PRODUCT OR SERVICE WILL NOT EXCEED THE GREATER OF (A) THE AMOUNT YOU ACTUALLY PAID US FOR THE SPECIFIC PRODUCT GIVING RISE TO THE CLAIM IN THE TWELVE (12) MONTHS PRECEDING THE EVENT, OR (B) ONE HUNDRED U.S. DOLLARS ($100.00).

Some jurisdictions do not allow the exclusion or limitation of certain damages. In those jurisdictions, our liability is limited to the maximum extent permitted by law.

20. Indemnification

You agree to defend, indemnify, and hold harmless the Company and its owners, officers, employees, contractors, and affiliates from and against any claims, liabilities, damages, losses, costs, and expenses (including reasonable attorneys’ fees) arising out of or related to: (a) your breach of these Terms; (b) your use of any Product or Service; (c) your User Content; (d) your violation of any law or third-party right; or (e) any wrongful chargeback or payment dispute initiated by you.

21. Binding Arbitration and Class Action Waiver

PLEASE READ THIS SECTION CAREFULLY. IT REQUIRES INDIVIDUAL ARBITRATION OF DISPUTES AND WAIVES YOUR RIGHT TO A JURY TRIAL OR CLASS ACTION.

Except for claims for injunctive relief related to our Intellectual Property and except for small-claims matters within jurisdictional limits, any dispute, claim, or controversy arising out of or relating to these Terms, our Products, or our Services (a “Dispute”) will be resolved exclusively through final and binding individual arbitration, administered by the American Arbitration Association (“AAA”) under its Consumer Arbitration Rules.

Arbitration will be conducted by a single arbitrator in the State of South Carolina, or by remote or online proceeding at the arbitrator’s discretion. The arbitrator’s award is final and may be entered as a judgment in any court of competent jurisdiction.

Class Action Waiver. You and we agree that any Dispute will be brought only in an individual capacity, and not as a plaintiff or class member in any purported class, collective, consolidated, or representative proceeding. The arbitrator may not consolidate claims or preside over any form of representative or class proceeding.

Opt-Out. You may opt out of this Section by sending written notice to snwelsh21@gmail.com with the subject line “Arbitration Opt-Out” within thirty (30) days of your first purchase. Opt-out notices received after that period are not effective. If this arbitration provision is found unenforceable for any reason, the parties agree to the exclusive jurisdiction and venue described in Section 22.

22. Governing Law and Venue

These Terms are governed by the laws of the State of South Carolina, without regard to its conflict-of-laws rules. Subject to Section 21, you and we consent to the exclusive jurisdiction and venue of the state and federal courts located in the State of South Carolina for any Dispute not subject to arbitration, and you waive any objection to such jurisdiction or venue based on inconvenient forum or any other ground.

23. Force Majeure, Severability, and Waiver

We are not liable for any failure or delay in performance caused by events beyond our reasonable control, including acts of God, natural disasters, war, terrorism, civil unrest, pandemic, government action, internet or platform outage, cyberattack, or failure of a third-party provider.

If any provision of these Terms is held to be invalid or unenforceable, that provision will be modified to the minimum extent necessary to make it enforceable, and the remaining provisions will continue in full force and effect. Our failure to enforce any provision is not a waiver of our right to enforce it later. You may not assign these Terms without our prior written consent; we may assign them freely, including in connection with a merger, acquisition, asset sale, or reorganization.

24. Entire Agreement, Modifications, and Contact

These Terms, together with our Privacy Policy and any signed agreement for specific paid services (including any institutional license agreement), constitute the entire agreement between you and us regarding the subject matter and supersede all prior agreements, communications, and understandings, written or oral. In the event of a conflict, a signed service or license agreement controls over these Terms for the specific service it covers.

We may update these Terms from time to time. The updated Terms will be posted with a new Effective Date, and material changes will be communicated where reasonably practicable. Your continued use of the Services or any Product after the Effective Date constitutes your acceptance of the updated Terms. The Terms in effect at the time of your purchase govern that purchase.

Legal notices to us, including arbitration opt-outs and DMCA notices, must be sent to snwelsh21@gmail.com. For customer support and order-related questions, contact snwelsh21@gmail.com. Notices to you may be sent to the email address on file with your purchase and are deemed delivered when sent.

25. Acknowledgment

BY PURCHASING OR USING ANY PRODUCT OR SERVICE, YOU ACKNOWLEDGE THAT YOU HAVE READ AND UNDERSTOOD THESE TERMS, INCLUDING THE ALL SALES FINAL / NO REFUNDS POLICY (SECTION 7), THE CHARGEBACK PROVISIONS (SECTION 8), THE DISCLAIMER OF WARRANTIES (SECTION 18), THE LIMITATION OF LIABILITY (SECTION 19), AND THE BINDING ARBITRATION AND CLASS ACTION WAIVER (SECTION 21), AND THAT YOU AGREE TO BE BOUND BY THEM.
