Direct-reading colorimetric diffusion tubes requiring no pump are available for a small number of substances (Table 10 diabetic diet meal plans . Because of their simplicity diabetes type 2 kaneel , colour indicator tubes are widely used but their limitations must be appreciated; sources of inaccuracy are given in Table 10 diabete wikipedia . Portable or fixed multi-point colorimetric detectors are available which rely on paper tape impregnated with the reagent. A cassette of the treated paper is driven electrically at constant speed over a sampling orifice and the stain intensity measured by an internal reflectometer to provide direct read out of concentration of contaminant in sample. Such instruments are available for a range of chemicals including the selection given in Table 10. Flammable gases Flammable atmospheres can be assessed using portable gas chromatographs or, for selected compounds, by colour indicator tubes. The flammable gas is oxidized on the heated catalytic element, causing the electrical resistance to alter relative to the reference. Instruments are calibrated for specific compounds in terms of 0–100% of their lower flammable limit. Recalibration or application of correction factors is required for different gases. These types of sensor are subject to ‘poisoning’ by certain chemicals such as silicone, sulphur, and halogen compounds. Again, errors can arise if the instrument is used for gases other than those for which it is calibrated. These sensors offer a long life expectancy; they are not restricted to flammable substances. Many such particles are invisible to the naked eye under normal lighting but are rendered visible, by reflection, when illuminated with a strong beam of light. This is the ‘Tyndall effect’ and use of a dust lamp provides a simple technique for the rapid assessment of whether a dust is present, its flow pattern, leak sources, the effects of ventilation, etc. Whether personal, spot or static sampling is adopted will depend upon the nature of the information required. Air in the general atmosphere, or in the breathing zone of individuals, may be collected using a pump coupled to a means of isolating particulate matter for subsequent analysis or determination (Table 10. Since different organic vapours interact with the flame ionization detector (FlD) to varying extents, it is vital that the instrument user be aware of the magnitude of the variation in order to obtain the most accurate data. This is accomplished using the portable isothermal pack (PlP) kit which is supplied with three 8 in (203 mm) columns packed with B, G and T materials respectively. Isothermal control is accomplished non-electrically using an ice-water mixture for 0°C and a seeded eutectic mixture for 40°C. The data listed are for comparison purposes only since retention time for a compound can vary according to the condition of the column packing material, packing procedure and chemical interaction among the components of a vapour mix.

Insertion of the tube incorrectly into the pumphousing (the correct direction is indicated on the tube). Leaks in sample lines, or insufficient time allowed to lapse between pump strokes when extensions are used. Tubes should be stored under refrigerated conditions but allowed to warm to ambient temperature prior to use. Use of tubes under conditions of temperature, pressure or humidity outside the range of calibration. Unless pumps possess a limiting orifice they should be calibrated with the air indicator tube in position. Interference due to the presence of other contaminants capable of reacting with the tube reagent. Equipment for personal monitoring comprises a lapel-mounted filter holder connected to a portable pump with a flow rate of about 3 litres/min. In order to ensure uniformity of fractionation, smooth and constant flow rates are essential.

This demographic change has important implications to women planning a pregnancy, their partners and families, their future chil dren, the service providers who work with pregnant women, and to the health care system. With advances in preconception and prenatal care, most women over the age of 35 can expect to have a healthy pregnancy and a healthy baby. However, there are some concerns in pregnancy that may increase the risk for this population. Many of these risks can be successfully managed through preconception and prenatal care. Focused care for women over age 35 plays a vital role in minimizing health risks, sensitively meeting their unique psychosocial needs, and maximizing health opportunities to achieve the best possible outcome, a healthy baby and a healthy mother. For simplicity, this manual uses “after age the term “advanced 35” and “over age 35” when discussing advanced maternal age. This older terminology is no longer considered by health care to be supportive or appropriate for this growing population. This manual is designed as a reference and does not duplicate best practice care guidelines. Women in their first pregnancies need different information and have different concerns. However, not all of the information found in the literature or from key informant interviews was specific to women having their first baby. Where possible, the information in this manual is separated for women having their first or subsequent babies after age 35. Reflecting on the Trend: Pregnancy After Age 35 3 Manual Development the information in this manual was obtained through a literature review in the fall of 2006. Also included in the review are reports from various Canadian organizations, some U. Journal articles prior to 1996 were used in the development of this manual if they were recently re-referenced. Keywords used in the search of these databases include: “delayed pregnancy”, “advanced maternal age”, “older mother”, “pregnancy”, “obstetrics”, “obstetrical outcomes”, “primip”, “elderly primip”, “elderly primagravid”, “older gravida”, “elderly gravida”, “maternal age”, “maternal health services”, “later pregnancy”, “maternal age, 35 and over”, “risks”, “pregnancy”, “pregnancy outcomes”, “risk factors”, “amniocentesis”, “interventions”, “genetic counselling”, “stillbirths”, “spontaneous abortion”, “ectopic”, “obstetric labour/labour complications”, “infant, mortality”, “down syndrome”, “genetic screening”, “screening”, “preconception care”, “preconception health”, “fetal death”, “ultrasound, neck”. In addition to the literature search, information was also obtained through interviews with Ontario service providers with expertise in providing prenatal services for women over age 35. Limitations the information in this manual has some limitations due to lack of research in some areas and lack of Ontario specific data. Some aspects of pregnancy over age 35 have not been studied, and more research is needed. While the main focus of this report is Ontario populations, in some areas the manual relies on data from other provinces, Canada, the United States and other countries, which may have limited relevance for Ontario. In addition, there were few opportunities to include the voices of pregnant women over age 35 in the development of this resource. However, age 35 is not an absolute number at which to expect risks for women in pregnancy and childbirth. Rather, age is service providers to merely one factor for service providers to consider in the context of look at advanced maternal prenatal care. Other factors include health status of the mother, age in a comprehensive nutrition, medical and family histories, and access to prenatal care. It is also important to recognize that while there are some manner, considering increased health risks associated with advanced maternal age, health risks and there are also psychosocial and health advantages. Most pregnant advantages, preconception women over age 35 would be considered “low risk” and would be able to choose among a variety of care providers and birth options. They, in turn, provide a range of antenatal services to pregnant women over age 35, including preconception and prenatal care, prenatal classes and drop-in programs for pregnant women. While some of the information and strategies in this manual are medical in nature, it is helpful if all service providers who work with women have a sense of the health risks, opportunities and recommended care for pregnant women who are over age 35. Service providers can refer women for more information, support or specific services, answer some questions and/or provide written information, even if they do not provide medical care. The information in this manual may help a wide range of providers to improve the services they offer to women over age 35, in a number of different ways.
