At sites perceived as higher risk discount 800 mg cialis black erectile dysfunction drugs generic, weekly or monthly large volume samples (1 litre or more) can provide assurance that regulatory standards are being met with a high enough margin of safety 4. Some sites provide automatic control of set-point based on the outlet residual - so called, cascade control. Wider experience of such control is that set-points do not need frequent adjustment and that automated adjustment can cause control instability unless systems are very carefully set-up. While some international water utilities currently use triple redundancy for chlorine measurements, many are moving to dual redundancy on large schemes. The move from triple to dual redundancy is influenced by several factors: The reliability of sensors and their associated electronics has improved substantially, so the reduced likelihood of failure with three instruments compared with two for a given maintenance frequency is less significant; Three sensors require 50% more maintenance than two; Triple/dual redundancy only works where measurement systems are independent. Each system should have its own sample supply, power supply, buffer pump (if applicable) etc. In practice there are triplicated systems with, for example, a common power supply; duplicate buffer pumps. In this case neither dual nor triple redundancy offers protection against faults caused by the sampling system. One approach is to have a separate sample flow alarm to protect against this failure mode. All single sample lines on duplicated or triplicated instruments should include an alarm for loss of sample flow. In summary, a properly designed dual redundancy system where risk of “common mode” failures has been minimised, is potentially much more reliable than a compromised triple redundancy system. It is recommended that dual redundancy be employed for free chlorine monitoring following chlorination on schemes serving populations >5000 persons. The instantaneous demand is the difference between the initial mass dose of chlorine and the subsequent measurement of chlorine residual immediately downstream. Data averaging may be required due to the time lags involved and the variability in the inlet residual that is under feedback control. Implementation of “instantaneous” demand monitoring requires calculation of the mass rate of chlorine which is then divided by process flow. Mass rate of chlorine can be determined readily for chlorine gas and commercial hypochlorite, but is more difficult to determine for hypochlorite generated on site. Chlorine gas: can be estimated indirectly from position of the gas control valve (e. Commercial hypochlorite: can be determined from volumetric flowrate and analysis of chlorine content. Hypochlorite generated on site: this is a difficult application as chlorine content varies with the operating conditions at generation and decays relatively quickly unless storage conditions are optimised. Proper implementation of demand monitoring against suitable upper (and lower) limits will increase security of disinfection, and can provide early warning of development of treatment problems and potential difficulties in maintaining the target Ct. They include organochlorine compounds formed by reaction between chlorine and organic matter in the water being treated, and inorganic by-products (e. The formation of organochlorine compounds is not influenced by the initial source of chlorine (i. The principle concern with chlorination by-products is their potential health effect, although their impact on taste and odour may be a further consideration in some situations. Bromate can be produced consequent to electrolytic generation of hypochlorite, either on site or during commercial production. These guideline values are unlikely to present a problem for commercial hypochlorite, provided that the product meets the relevant European standard (see Section 4. No limits for chlorate or chlorite are in place when commercial hypochlorite is used. In these situations, dechlorination is usually achieved though dosing of reducing chemicals such as sulphur dioxide, sodium thiosulphate or sodium bisulphite, to provide a high degree of control over the dechlorination process. Superchlorination/dechlorination in this context is rarely practiced in Ireland but may be a possible solution at disinfection installations where inadequate Ct exists downstream. There may also be situations where dechlorination is needed before discharge of chlorinated water to the environment, or to protect downstream processes. Other less controllable dechlorination systems might then be used, such as activated carbon or aeration. Chlorinated waters from potable water systems are released to the environment through activities such as water main flushing, disinfection of new mains, distribution system maintenance, water main breaks, filter backwash and other utility operations. Although chlorine protects humans from pathogens in water, it is highly toxic to aquatic species in receiving waters.

Asthma control – assess both symptom control and risk factors • Assess symptom control over the last 4 weeks (Box 4 order cialis black 800 mg without a prescription kidney disease erectile dysfunction treatment, p9) • Identify any other risk factors for poor outcomes (Box 4) • Measure lung function before starting treatment, 3–6 months later, and then periodically, e. Treatment issues • Record the patient’s treatment (Box 7, p14), and ask about side-effects • Watch the patient using their inhaler, to check their technique (p18) • Have an open empathic discussion about adherence (p18) • Check that the patient has a written asthma action plan (p22) • Ask the patient about their attitudes and goals for their asthma 3. Asthma control has two domains: symptom control (previously called ‘current clinical control’) and risk factors for future poor outcomes. Risk factors are factors that increase the patient’s future risk of having exacerbations (flare-ups), loss of lung function, or medication side-effects. Level of asthma symptom control In the past 4 weeks, has the patient had: Well Partly Uncontrolled controlled controlled Daytime symptoms more than twice/week? Risk factors for poor asthma outcomes Assess risk factors at diagnosis and periodically, particularly for patients experiencing exacerbations. Other major independent risk factors for flare-ups (exacerbations) include: • Ever being intubated or in intensive care for asthma • Having 1 or more severe exacerbations in the last 12 months. Once asthma has been diagnosed, lung function is most useful as an indicator of future risk. It should be recorded at diagnosis, 3–6 months after starting treatment, and periodically thereafter. Patients who have either few or many symptoms relative to their lung function need more investigation. Asthma severity can be assessed retrospectively from the level of treatment (p14) required to control symptoms and exacerbations. Severe asthma is asthma that requires Step 4 or 5 treatment, to maintain symptom control. How to investigate uncontrolled asthma in primary care This flow-chart shows the most common problems first, but the steps can be carried out in a different order, depending on resources and clinical context. The aim is to reduce the burden to the patient and their risk of exacerbations, airway damage, and medication side-effects. The patient’s own goals regarding their asthma and its treatment should also be identified. Population-level recommendations about ‘preferred’ asthma treatments represent the best treatment for most patients in a population. Patient-level treatment decisions should take into account any individual characteristics or phenotype that predict the patient’s likely response to treatment, together with the patient’s preferences and practical issues such as inhaler technique, adherence, and cost. A partnership between the patient and their health care providers is important for effective asthma management. Training health care providers in communication skills may lead to increased patient satisfaction, better health outcomes, and reduced use of health care resources. Health literacy – that is, the patient’s ability to obtain, process and understand basic health information to make appropriate health decisions – should be taken into account in asthma management and education. Before starting initial controller treatment • Record evidence for the diagnosis of asthma, if possible • Document symptom control and risk factors • Assess lung function, when possible • Train the patient to use the inhaler correctly, and check their technique • Schedule a follow-up visit After starting initial controller treatment • Review response after 2–3 months, or according to clinical urgency • See Box 7 for ongoing treatment and other key management issues • Consider step down when asthma has been well-controlled for 3 months 13 Box 7. Other options: Add-on tiotropium by soft-mist inhaler for adults (≥18 years) with a history of exacerbations. Patients should preferably be seen 1–3 months after starting treatment and every 3–12 months after that, except in pregnancy when they should be reviewed every 4–6 weeks. The frequency of review depends on the patient’s initial level of control, their response to previous treatment, and their ability and willingness to engage in self-management with an action plan. Stepping up asthma treatment Asthma is a variable condition, and periodic adjustment of controller treatment by the clinician and/or patient may be needed. Stepping down treatment when asthma is well-controlled Consider stepping down treatment once good asthma control has been achieved and maintained for 3 months, to find the lowest treatment that controls both symptoms and exacerbations, and minimizes side-effects. To ensure effective inhaler use: • Choose the most appropriate device for the patient before prescribing: consider medication, physical problems e. Check and improve adherence with asthma medications Around 50% of adults and children do not take controller medications as prescribed.
