9. The most important factor in determining percent oxygen saturation of hemoglobin is 10. Which of the following statements are true? 11. Place the steps for normal inhalation in order 12.Match the following a) Total volume of hair inhaled and exhaled each minute b) Tidal volume+ inspiratory reserve volume+ expiratory reserve volume c) Additional amount of air inhaled beyond tidal volume when taking a very deep breath d) Residual volume + expiratory reserve volume e) Amount of air remaining in lungs after expiratory reserve volume is expelled f) Tidal volume+ residual volume g) Vital capacity+ residual volume h) Volume of air in one breath i) Amount of air exhaled in forced exhalation following normal exhalation j) Provides a medical and legal tool for determining if a baby was born dead or died after birth.
Spirometry A breathing test called Spirometry will often be carried out to assess how well your lungs work. This involves taking a deep breath and exhaling as fast as you can through a mouthpiece that is attached to a machine called a spirometer. The spirometer takes two measurements – the volume of air you can breathe out in the first second of exhalation and the total amount of air you breathe out. You may be asked to breathe into spirometer a few times to get an accurate reading. The readings are then compared with average measurements for people your age, sex and height, which can show if your airways are obstructed.
http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
1.2 Describe the impact of specific conditions on the correct movement and positioning of an individual. If you have someone who has had a stroke this may cause them to loose the use of their limbs which mean that it is important to remember that you dress the bad side first and undress it last. This is so you are not pulling their muscles in the direction they won’t go. 3.3 Identify any immediate risks to the individual. Risks can occur every day which is why it is important to always check to identify the risks straight away and try to correct it weather it is the wires are hanging down on the bed which could be a risk if the hoist gets trapped on them, or even if the sling you are using has a tear in the seam.
The only “prokinetic” (meaning it increases the tone and motility of the GI tract) agent currently available. Used for GERD, N/V, diabetic gastroparesis, and postoperative emesis. A common side effect is DIARRHEA and will likely need to hold the medication if diarrhea occurs. A more troublesome side effect with long-term use is tardive dyskinesia, a movement disorder that is usually permanent. • S=“Statins”.
COPD 2 INTRODUCTION COPD, chronic obstructive pulmonary disease is an overall term for the conditions of chronic bronchitis and emphysema. It is noted that bronchodilator therapy is necessary in managing the symptoms; also, reducing exacerbations improving the quality of life. Primary care generally diagnoses and manages COPD. COPD is a progressive condition where air flow becomes limited which makes it difficult to breathe. This is the third leading cause of death in the United States.
Airborne Precautions Airborne precautions are required to protect against airborne transmission of infectious agents. Diseases requiring airborne precautions include, but are not limited to: Measles, Severe Acute Respiratory Syndrome (SARS), Varicella (chickenpox), and Mycobacterium tuberculosis. Preventing airborne transmission requires personal respiratory protection and special ventilation and air handling Airborne precautions include: * Standard Precautions * Personal respiratory protection * N95 respirator Prior fit-testing that must be repeated annually and fit-check / seal-check prior to each use. or * Powered Air-Purifying Respirator (PAPR) * PAPR More information about PAPR respirators. * Airborne Infection Isolation Room (AIIR) * At a minimum, AIIR rooms must: * Provide negative pressure room with a minimum of 6 air exchanges per hour * Exhaust directly to the outside or through HEPA (High Efficiency Particulate Air) filtration * Contact Precautions * In addition to standard precaution, use Contact Precautions in the care of patients known or suspected to have a serious illness easily transmitted by direct patient contact or by indirect contact with items in the patient’s environment.
Individuals with head injuries, those subjected to brain operations and those barbiturate poisoning may have hyperthermia especially in a hot environment, due to a disturbance in the heat regulatory center of the brain. Obviously an important factor in recovery is an environment in which the patient can lose heat by radiation and evaporation – In other words – An air conditioned room. Considerations in hospital Air-conditioning Hospital air-conditioning, as we have seen briefly earlier, differs from conventional air-conditioning in certain very critical areas. They can be enumerated as follows: Complex air filtration systems Air filtration systems for operating theatres, intensive care units and etc. , are fairly compels calling not only for specials filters but two or three sets of filters in series to keep air borne particles and bacteria at minimum level.
This principle was first used in a rocket engine by Robert Goddard. Very nearly all modern rocket engines that employ hot gas combustion use de Laval nozzles. Its operation relies on the different properties of gases flowing at subsonic and supersonic speeds [1, 2]. The speed of a subsonic flow of gas will increase if the pipe carrying it narrows because the mass flow rate is constant. The gas flow through a de Laval nozzle is isentropic (gas entropy is nearly constant).
