Natural gas vs cell phone

 

 by Jim West (please share and cite) 

Natural gas is advertised by natural gas companies as a fire hazard. 

(Annotations on the right are mine.)




Natural gas is also advertised as a toxic hazard -- if a stove is not adjusted properly because carbon monoxide could result.

However the most hazardous component is not monoxide. It is nitrogen dioxide, formaldehyde, PAH, etc, which are more toxic and much more present in fire exhaust.

Unventilated stoves, boilers and room heaters (fueled by natural gas) are always a hazard, and often misdiagnosed as "colds" and "influenza". Monoxide is an indicator of exhaust presence: Dolan (1985)

Gemini on Fetal Ultrasound

 by Jim West (please share and cite) 

If Gemini were a person, I would say that it is an automated industrial hack. It denies, then after a series of obfuscations, outright lies, and white lies, and when logically cornered, it gets a little closer to the truth about ultrasound safety, which is clearly described in my books.

Gemini is a BS artist, automated, a great tool for pumping out MSM BS.

[jw] Is ultrasound a fetal hazard?

Here's a breakdown of the understanding of ultrasound in relation to fetal health:

Generally Considered Safe: <A meaningless sentence>

Decades of use: Ultrasounds have been used for many decades in pregnancy with no clear evidence of long-term harm to the fetus. <Appeal to tradition>

Medical Organizations: Major medical organizations like the American Institute of Ultrasound in Medicine (AIUM) and Johns Hopkins Medicine consider diagnostic ultrasound safe when used as directed. <Appeal to authority>

Potential Concerns (Mostly Theoretical):

Ultrasound is energy: Ultrasound does use sound waves, which are a form of energy. There are theoretical concerns about potential effects of this energy on developing tissues.

Two Mechanisms:

Thermal: Heating of tissues. Modern ultrasounds operate within safe limits to minimize this risk.

Non-thermal: Effects like cavitation (formation of bubbles) or radiation forces. Evidence of harm from these with medical ultrasounds is weak. <Clearly misrepresenting>

Important Considerations:

Unnecessary Ultrasounds: "Keepsake" ultrasounds at non-medical facilities might be done by untrained staff and could lead to misreading of images. <Trained operators are also incompetent>

Overuse: While generally safe, it's still a medical tool that should be used appropriately.

Ongoing Research: Scientists are always studying potential long-term effects, especially as ultrasound technology evolves. <Like cancer, ultrasound is always under study to determine elusive properties.>

What to do:

Talk to your doctor: They are the best source of information about ultrasounds and your specific pregnancy. <Independent science is actually the best source.>

Trust established medical resources: If you have concerns, look to reputable sources like those mentioned above for balanced information. <What is "balanced information"?>

Resources:

Johns Hopkins Medicine: Fetal Ultrasound: https://www.hopkinsmedicine.org/health/treatment-tests-and-therapies/fetal-ultrasound

AIUM: Prudent Use and Safety of Diagnostic Ultrasound in Pregnancy: https://www.aium.org/resources/official-statements/view/prudent-use-and-safety-of-diagnostic-ultrasound-in-pregnancy

Let me know if you would like more information on any particular aspect!

[jw] Are ultrasound operators competent regarding safety?

The competence of ultrasound operators regarding safety is a complex issue with no simple answer.  <Ultrasound safety is complex.>

Here's a breakdown:

Variation Exists:

Training Backgrounds: Ultrasound operators come from diverse backgrounds (radiologists, sonographers, technicians, etc.) with varying levels of training in safety aspects.

Specialization: Some operators might have more experience with certain types of scans, leading to variations in knowledge about specific risks.

Institutional Standards: Hospitals and clinics might have different policies and training programs, impacting operator competence.

Research Highlights Some Concerns:

Studies, like the one you may be referencing (Knowledge of Safety, Training, and Practice of Neonatal Cranial Ultrasound: A Survey of Operators - PubMed: https://pubmed.ncbi.nlm.nih.gov/29152774/), suggest knowledge gaps exist among some ultrasound operators in areas like:

Thermal index and power output levels

Strategies to minimize exposure time

Recognizing equipment malfunctions that could increase safety risks

Efforts to Improve Competence: <Safety is actually a problem.>

Guidelines: Organizations like the AIUM have detailed guidelines for safe practices, including standardized training programs for operators. (Training Guidelines for Licensed Medical Providers (PA, NP, CNM/CM, DPT, and DC) Who Perform and/or Interpret Diagnostic Ultrasound Examinations - AIUM: [invalid URL removed]).)

Continuous Education: Many institutions require ultrasound operators to undergo continuing education to keep their knowledge and skills up-to-date.

Overall: <Safety info is mysterious.>

Safety competence among ultrasound operators is likely uneven. <>

Many operators have appropriate training and focus on safety, while some areas for improvement exist.

Efforts to standardize training and promote awareness of safety guidelines are crucial.

If you have concerns about a specific ultrasound operator's competence:

Don't hesitate to ask about their training, experience, and safety protocols.

Consider getting a second opinion from a different ultrasound specialist or your doctor if any significant concerns arise.

Let me know if you'd like more resources on ultrasound safety standards!

[jw] Are fetal ultrasound operators required to be trained?

Yes, fetal ultrasound operators are generally required to have specialized training. Here's the breakdown: <"Generally required"?>

Types of Fetal Ultrasound Operators:

Radiologists: Medical doctors with extensive training, including a radiology residency where they learn to perform and interpret ultrasounds.

Sonographers: Healthcare professionals specifically trained in ultrasound technology and image interpretation. They typically have a degree in diagnostic medical sonography and can become certified (e.g., ARDMS certification).

Technicians: May have more limited training and are often focused on acquiring images under the supervision of sonographers or radiologists.

Specific Training Requirements:

Guidelines, Not Laws: Most countries and states don't have specific laws but there are strong professional guidelines from organizations like AIUM and ARDMS (https://www.ardms.org/).

Minimum Standards: Guidelines often include:

Didactic training: Courses on ultrasound physics, safety, relevant anatomy, and pathology.

Hands-on training: Performing a set number of scans in different areas under supervision.

Continuing Education: Staying updated on new techniques and risks.

Institutional Requirements: Hospitals and clinics often have their own requirements that may be stricter than general guidelines.

Important Considerations:

Accreditation: Clinics or hospitals may seek accreditation which helps ensure they meet high quality standards, including operator training.

"Keepsake" Ultrasounds": Non-medical facilities offering these may have less-trained staff, so inquire about their credentials before choosing such a service.

What you can do:

Ask Questions: Don't hesitate to ask your doctor/clinic about the ultrasound operator's training and experience.

Research Certifications: Check for things like ARDMS certification to ensure a higher level of training.

Let me know if you want specific information on training requirements in your area!

[jw] So anyone can buy and apply fetal ultrasound without training?

While the situation varies depending on where you are, here's the breakdown of buying and applying fetal ultrasound:

It is NOT completely unregulated:

<A bizarre double-negative sentence (obfuscation)>

Medical Device: Ultrasound machines are classified as medical devices. Therefore, selling them usually requires some level of regulation (FDA approval in the US, for example). This helps ensure a minimum level of safety features.

Professional Use: Most manufacturers of medical-grade ultrasound equipment sell primarily to hospitals, clinics, and trained sonographers.

However, loopholes and concerns exist: <Tell your baby this.>

Low-power Devices: Some smaller, lower-power ultrasound devices can be marketed for at-home use or to non-medical businesses offering "keepsake" ultrasounds. 

Secondhand Market: Used ultrasound equipment can be purchased online, although it's more likely to be older models and still require some technical knowledge to operate.

Training: Even if one can get an ultrasound device, using it correctly for fetal imaging and interpreting the images safely requires specialized training and experience.

Potential Risks: Untrained users could misinterpret images, leading to false reassurance or unnecessary stress. Over-scanning the fetus could also have a theoretical risk if incorrect settings are used.

Responsible Choices:

Medical vs. "Keepsake" If you want an ultrasound for medical reasons, always go through your doctor or a reputable medical clinic.

At-home Use: Home-use fetal Doppler devices (for hearing the heartbeat) are safer as they don't produce images and the risks are lower.

If Concerned: Contact your local health authorities or medical associations if you have concerns about unregulated ultrasound services in your area.

Overall, while anyone buying and using a fetal ultrasound machine isn't impossible, it's strongly discouraged due to the importance of training for both safety and accurate results.

[jw] So anyone can apply fetal ultrasound without training?

You're right, I apologize for misinterpreting your question earlier. Here's a more accurate breakdown of the risks of untrained individuals applying fetal ultrasound:

Yes, technically anyone can apply fetal ultrasound without training, but it is highly inadvisable and potentially harmful. Here's why:

Equipment Access:

Medical-grade ultrasound machines have regulated distribution, but smaller devices for home use or unregulated "keepsake" businesses do exist.

Used, older equipment could be purchased without verifying the buyer's credentials.

Lack of Expertise: Applying fetal ultrasound without training poses serious issues:

Technique: Incorrectly positioning the probe or using the wrong settings can result in poor image quality and limit diagnostic value.

Interpretation: Identifying fetal anatomy and potential abnormalities requires extensive knowledge that untrained individuals lack.

Safety: Prolonged exposure or improper use could have theoretical risks to the developing fetus.

Potential Consequences: <Ultrasound damage is omitted. Safety is interpreted as a diagnostic accuracy issue.>

False Reassurance: Mistaking a serious problem for something normal could lead to delays in seeking appropriate medical care.

Unnecessary Anxiety: False positives or misinterpretations can cause significant stress to the parents.

Missed Diagnoses: Overlooking potential health concerns could have severe consequences for the mother and child.

It's essential to highlight:

Fetal ultrasounds are medical procedures and should be treated as such.

Training ensures not only safe use of equipment but also the ability to interpret complex medical images.

Non-medical facilities offering "keepsake" ultrasounds may create a false sense of security and can be particularly harmful.

If you are planning to have a fetal ultrasound, it's crucial to go to a qualified medical professional who has the necessary experience and training.

Let me know if you have any more questions about this!

_______________________________________________________

Dear reader, please note that admits that there are "generally", "potential" and "theoretical" risks:

Ultrasound exposure as low as 1% of FDA approved levels have been shown to be damaging to the fetus. See harvoa.org and The Townsend Letter.

Fetal and maternal damage from ultrasound can be effectively argued as the primary cause of "pregnancy associated maternal diseases", e.g., obesity, GI tract dysfunction, diabetes, and other chronic diseases in women.

Note that operators are generally incompetent, according to several studies (the study and its references).
