Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of Mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of Mechanical ventilation systems, which arespace consuming. The Mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.

Aim: The aim of this study was to describe intensive care nurses? experiences communicating with patients during Mechanical ventilation.Methods/design: A qualitative interview study. Interviews where analyzed using descriptive content analysisSetting: Nine intensive care nurses from two different intensive care units were interviewed using a semi structured interview guide.Background: Past research has shown that patients during Mechanical ventilation in the intensive care unit, feel very vulnerable and the helplessness of being unable to speak. These patients feels that they are completely dependent on the nurses and their competence. It has been shown to be very important that the patient feels included, acknowledged and respected.Results: The analyzed data resulted in a theme; through communication strive to preserve patients´ dignity and three main categories; create relationship to the patient, minimize patients´ vulnerability and don´t give up.

?Studies have shown that patients receiving Mechanical ventilation in an intensive care unit (ICU), who are entirely dependent on the nursing staff, often experience frustration due to a temporary loss of the voice source. Limited communication is an important factor contributing to patient discomfort. Nursing staff also report communication as frustrating and difficult.The aim of the present study is to introduce a neck-type electrolarynx as a communication aid in an ICU, to study the nursing staff experiences of communication with tracheotomized patients receiving Mechanical ventilation, and to examine the patient´s experiences regarding communicative abilities. Communication between a ventilator treated, tracheotomized patient and members of the nursing staff was recorded and analyzed according to principles of Conversation Analysis (CA).The results show that several members of the nursing staff experience difficulties communicating with tracheotomized patients receiving Mechanical ventilation.

sustainable development by reducing the energy use by EU:s directive of energy efficiency and the UN Convention. The second purpose is to present the technical solutions regarding ventilation and heating system that is being used in passive houses. This was done using 8 passive houses, 4 germany and 4 swedish passive houses. Even the international and Swedish system requirements for passive houses have been addressed in this project. The goal was also to explain how and why the mechanical system in passive houses has developed to the technology used today.

Studien går ut på att jämföra tre olika styrsystem för ventilation, nämligen CAV (Constant Air Ventilation), VAV (Variabel Air Ventilation) och DCV (Demand Controlled Ventilation). Dessa styrsystem ställs mot varandra i tre olika lokaltyper, med syfte att identifiera det mest energieffektiva styrsystemet. Ett syftet med studien är också att upptäcka vid vilka flöden det lönar sig att arbeta med VAV- och DCV-styrsystemen..

This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab.The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics.The background of the problem with moisture is that today?s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate.

ABSTRACTIntroduction: Postoperative wound infection is the third most common nosocomial infection in Sweden. The ever-growing problem of antibiotic resistance provides surgical departments a big challenge when it comes to preventing the spread of infection. Operating theatre nurses have a vital role in the prevention of infection. In addition, correct ventilation in the operating theatre is of great importance. The caregiver is responsible for quality assurance of ventilation in the operating theatre, but the work can be delegated to other staff within the department.

One problem in today?s indoor air quality lies within insufficient ventilation. Dynamic ventilation can be obtained by implementing a Demand-Controlled ventilation (DCV) system. DCV systems adjust the ventilation in a building by calculating the impact made by its? occupants.

This report will show the energy usage of Hotel Princess in Sandviken, Sweden. When the hotel changed owner an examination of the hotels heating, ventilation and sanitary systems were done. The report showed flaws in the ventilation system, and is why the new owner wanted a closer look at the energy use of the hotel. The original building was built in the 1930s and two major extensions have been built, one in the 1950s and the most recent in the 1980s. An assumption made is that the building parts were built to the restrictions during the time. Activities on the hotel include sleep over, conference, night club, massage and swimming in the hotels pool section.

Bakgrund. Enligt den nya kompetensbeskrivningen för anestesisjuksköterskor framgår bland annat att anestesisjuksköterskan ska ha kompetens att övervaka och följa upp ventilation och cirkulation hos sina patienter. Det har länge varit vanligt att använda volymkontrollerad ventilation (VCV) till patienter som genomgår bukkirurgi. Nu finns det ett annat alternativ, tryckkontrollerad ventilation (PCV). Det är ett omdiskuterat ämne huruvida det mer traditionella VCV eller det senare PCV ska tillämpas på patienter som genomgår bukkirurgi.

This rapport contains an examination of the energy consumption of a kindergarten, which areas that have the largest impact on the energy consumption and what can be done to reduce those areas in ways that are relatively easy and profitable. It is also analyzed if it is possible to reduce the energy consumption from today?s consumption to a consumption that fulfils the demands placed on low energy houses by FEBY.The focus has been on reducing the energy consumption of the areas ventilation, heating system and hot water system, since those seemed to be the easiest ones to affect and since the building is quite recently built.There are different kinds of ventilation systems, at the moment the building have a CAV-system, which means that the ventilation is too high during large parts of the day. There are different ways to manage the ventilation system, for example presence detection, humidity sensors, CO2 sensors, temperature sensors and season adjustment. Many of those are in the end dependent on CO2 sensors to guarantee a good indoor climate, therefore the focus have been placed on this system.

Examensarbetet som utförts på Institutionen för Maskinteknik vid Blekinge Tekniska Högskola i samarbete med Kockums AB har benämningen ? Upphängningssystem?. Dagens upphängning av rör, ventilationsrör och kabelbanor består av ett antal olika singelupphängningar utan större samordning. Detta har gjort att Kockums AB önskat få fram ett samordnat upphängningssystem som klarar av alla dessa upphängningstyper. Utifrån denna problemställning har vi arbetat oss fram till ett upphängningssystem bestående av ett multisystem och ett flertal singelupphängningar för rör, kabelbanor och ventilation.

The objective of this work was to introduce measures to reduce energy and water demand at Gävle Söder 17:10. To succeed, this energy audit has been made. The work is based on collected statistics from the property owner Norrporten, measurements, literature review and through consultation with experts in the field. Two models, one for each building, have been created in the simulation program BV2 to estimate the potential of energy measures based on the collected information. The models in BV2 have been verified against the statistics of the energy consumption.With the help of calculations and simulations, seven cost-effective measures have been identified.
