  • Hydrogen Peroxide, and This Is the Same Substance That Can Be Purchased in a 32-Ounce Plastic Bottle at Walmart, for 88 Cents, Or at Walgreens for Under a $1.00
    An At-Home Treatment That Can Cure Any Virus, Including Coronavirus Originally Conceptualized, circa 1990, by Charles Farr, MD Subsequently Researched and Prescribed by Frank Shallenberger, MD Current Protocol Created by Thomas Levy, MD, JD Although COVID-19, aka coronavirus, is deadly in some select cases, and it can spread rapidly, there is a simple, very inexpensive, and highly effective treatment that can treat and rapidly resolve coronavirus and virtually any other respiratory virus. While different individuals can be expected to have variable degrees of positive response, this intervention can be anticipated to eliminate eventual fatal disease outcomes in all but the most advanced cases. As I hope you will eventually experience, the treatment works for all acute viral infections, and especially well for flu viruses of any variety. In fact, although we are constantly conditioned to not believe in anything “too good to be true,” you will never have to worry about getting a cold or the flu again because you can cure it on your own. The key ingredient in this treatment is common household 3% hydrogen peroxide, and this is the same substance that can be purchased in a 32-ounce plastic bottle at Walmart, for 88 cents, or at Walgreens for under a $1.00. Perhaps you have never heard of hydrogen peroxide therapy, but since the treatment was first championed by Dr. Charles Farr in about 1990, thousands of doctors have used this therapy for decades to conquer infections in many thousands of patients throughout the world. How and Why Hydrogen Peroxide Works Because hydrogen peroxide consists of a water molecule (H2O) with an extra oxygen atom (H2O2), it is this extra oxygen atom that makes it so deadly for viruses.

  • Inhalation Anesthesia Machine / Vaporizer / Waste Gas Maintenance
    Office of Research Office of Responsible Research Practices Institutional Animal Care and Use Committee INHALATION ANESTHESIA MACHINE / VAPORIZER / WASTE GAS MAINTENANCE Overview/Purpose To reduce risk of anesthetic gas exposure to animals and personnel, proper maintenance of anesthesia equipment, appropriate waste scavenging systems, and safe administration techniques must be employed. Preventative maintenance is key in reaching this goal. ULAR machines are maintained by ULAR while maintenance of lab owned machines is required by the research team. Personnel must be properly trained to provide safe anesthesia to animals and in the proper use and maintenance of anesthetic machines. Training is available through ULAR http://ular.osu.edu/training/animal-handling-and-technique-training/. Definition 1. Anesthesia Machine. - The entire piece of equipment that is used to deliver precise amounts of inhaled anesthetic gas and/or a carrier gas (usually air, O2 or CO2, alone or in a mix). It consists of multiple parts (precision vaporizer, carrier gas regulators, flow meters, delivery/breathing circuits and scavenge systems and possibly a rebreathing reservoir (bag). a. Rebreathing systems – for animals weighing over ~5kg b. Non-rebreathing systems – for rodents and animals weighing under ~5kg. 2. Breathing Circuit: The tubing that delivers the fresh gas/anesthetic gas mixture from the machine to the patient. a. Rebreathing circuits direct the expired gases through a soda lime canister for absorption of carbon dioxide, which are then “rebreathed” by the patient. b. Non-rebreathing circuits are designed to deliver oxygen and anesthetic gases with less resistance to breathing in small patients and have a higher fresh gas flow to remove carbon dioxide.

  • Pharmacology – Inhalant Anesthetics
    Pharmacology- Inhalant Anesthetics Lyon Lee DVM PhD DACVA Introduction • Maintenance of general anesthesia is primarily carried out using inhalation anesthetics, although intravenous anesthetics may be used for short procedures. • Inhalation anesthetics provide quicker changes of anesthetic depth than injectable anesthetics, and reversal of central nervous depression is more readily achieved, explaining for its popularity in prolonged anesthesia (less risk of overdosing, less accumulation and quicker recovery) (see table 1) Table 1. Comparison of inhalant and injectable anesthetics Inhalant Technique Injectable Technique Expensive Equipment Cheap (needles, syringes) Patent Airway and high O2 Not necessarily Better control of anesthetic depth Once given, suffer the consequences Ease of elimination (ventilation) Only through metabolism & Excretion Pollution No • Commonly administered inhalant anesthetics include volatile liquids such as isoflurane, halothane, sevoflurane and desflurane, and inorganic gas, nitrous oxide (N2O). Except N2O, these volatile anesthetics are chemically ‘halogenated hydrocarbons’ and all are closely related. • Physical characteristics of volatile anesthetics govern their clinical effects and practicality associated with their use.

Email:[email protected] Received: 05 December 2017, Revised and Accepted: 02 January 2018 ABSTRACT Inhalation therapy is an effective way for local and systemic delivery of miscellaneous drugs for pulmonary and non-pulmonary diseases. The inhalation therapy aims to target specific cells or regions of the lung, bypassing the lung’s clearance mechanisms and thereby providing high retention of the drug for longer periods. It helps in improved penetration of intravenously administered antibiotics into lung parenchymal tissue and bronchial secretions, and as a result, their potential systemic toxicity is reduced when given over prolonged periods of time. The advancement in device technology supports the development of more efficient therapy in the form of delivering finer particles into the lung in large doses. Therefore, meticulous daily management of lung disease, together with prompt, aggressive treatment of exacerbations can be achieved through inhalation to preserve lung function. This review summarizes the features of inhalation delivery devices, their advantages and limitations, challenges in formulation and brief description of novel technologies currently marketed.

This is because of their high potency, high specificity and desirable safety profile. The majority of biological drugs are peptide- and protein-based therapeutics with poor oral bioavailability. They are normally administered by parenteral injection (with a very few exceptions). Pulmonary delivery is an attractive non-invasive alternative route of administration for local and systemic delivery of biologics with immense potential to treat various diseases, including diabetes, cystic fibrosis, respiratory viral infection and asthma, etc. The massive surface area and extensive vascularisation in the lungs enable rapid absorption and fast onset of action. Despite the benefits of pulmonary delivery, development of inhalable biological drug is a challenging task. There are various anatomical, physiological and immunological barriers that affect the therapeutic efficacy of inhaled formulations. This review assesses the characteristics of biological drugs and the barriers to pulmonary drug delivery.

  • The Importance of Inhalation Volume When Measuring Smoking Behavior
    Behavior Research Methods & Instrumentation 1983,15 (6),561-568 The importance of inhalation volume when measuring smoking behavior RONALD I. HERNING, JOHANNA S. HUNT, and REESE T. JONES Langley PorterPsychiatric Institute, University ofCalifornia, SanFrancisco, California Theoretical and technical considerations of measuring puff and inhalation volumes during cigarette smoking are reviewed. Measures of smoking behavior using a flowmeter and induc­ tance plethysmography are described and demonstrated with seven subjects smoking over a 3­ to 4-h period. Puff volume and duration, inhaled volume and duration, interpuff and intercig­ arette interval, and number of puffs varied for each individual over the session. The ratio of puff volume to inhaled volume changed with successive cigarettes. Smokers adjust the concentra­ tion of smoke by blending air with the smoke. Thus, to completely characterize smoking be­ havior, the volume of smoke and air inhaled into the lungs must be measured directly. Tobacco smokers have many options for varying ex­ ucts other than the psychoactive substance may have posure to nicotine, tar, and other combustion products serious health implications.

  • The Use of Povidone Iodine Nasal Spray and Mouthwash During the Current COVID-19 Pandemic May Protect Healthcare Workers and Reduce Cross Infection
    March 27, 2020 The use of Povidone Iodine nasal spray and mouthwash during the current COVID-19 pandemic may protect healthcare workers and reduce cross infection. J Kirk-Bayley MRCP FRCA EDIC FFICM, Consultant Intensivist & Anaesthetist, Royal Surrey County Hospital S Challacombe, PhD, FRCPath, FDSRCS, FMedSci, DSc(h.c), FKC, Martin Rushton Professor of Oral Medicine, KCL VS Sunkaraneni LLM FRCS(2019), Consultant Rhinologist, Royal Surrey County Hospital J Combes FDS FRCS (OMFS), Lt Col RAMC, Consultant Advisor (ARMY) in OMFS, Defence Medical Services Abstract In late 2019 a novel coronavirus, SARS-CoV-2 causing Coronavirus disease 2019 (COVID-19) appeared in Wuhan China, and on 11th March 2020 the World Health Organisation declared it to have developed pandemic status. Povidone-iodine (PVP-I) has a better anti-viral activity than other antiseptics, and has already been proven to be an effective virucide in vitro against severe acute respiratory syndrome and Middle East respiratory syndrome coronaviruses (SARS-CoV and MERS- CoV). Povidone iodine has been shown to be a safe therapy when inhaled nasally or gargled. We propose that a protocolised nasal inhalation and oropharyngeal wash of PVP-I should be used in the current COVID-19 pandemic to limit the spread of SARS-CoV-2 from patients to healthcare workers (and vice versa) and thus reduce the incidence of COVID-19. There should be regular use in patients with COVID-19 to limit upper respiratory SARS-CoV-2 contamination, but also use by healthcare workers prior to treating COVID 19 patients or performing procedures in and around the mouth/ nose during the pandemic, regardless of the COVID 19 status of the patient.
