Thermoregulation is the maintenance of physiologic core body temperature by balancing heat generation with heat loss.  NORMAL TEMPERATURE Is Modes of Heat Loss  Circadian Rhythms Body temperature is usually lower in the morning than in the evening. Age the body temperature of infants and children changes more rapidly in response to both heat and cold. Hormones Factors women tend to have more fluctuations in body temperature than men as a result of hormonal changes affecting Stress the body respond to both emotional and physical stress as a body threat increasing the production of epinephrine and nor epinephrine as a result the metabolic rate increases raising the temperature: body temperature Environmental temperature Response to a change in environment either by wearing or less clothes. Exercise, hard work or strenuous exercise can increase body temperature.  Pyrexia (fever) A body temperature above the usual Alterations range is called pyrexia, febrile, hyperthermia, or fever. in body temperature Hyperpyrexia (high grade fever) (High body is a very high fever usually above 41 temperature) °C and survival is rare when the temperature Reaches 44 °C and death due to damaging effects on the respiratory center.  Monitor vital signs Assess color and temperature of skin (pink & warm) Remove excess blanket when the client feels warm but provide extra warmth when the client feels chilled. Administer antipyretic as prescribed to reduce body temperature. Provide a tepid sponging to increase heat loss through conduction/ reduce body temperature Nursing Administer IV fluid for hydration as prescribed. Interventions Monitor WBC, and other laboratory (RP, UFEME) reports for indications of infection or dehydration for Client's Encourage for adequate fluid and food intake with fever: Measure intake and output Advise for bed rest to minimise unnecessary energy use that cause heat production. Provide oral hygiene to keep the mucous membrane moist Encourage lightweight clothing and covers. NURSING INTERVENTION: TEPID SPONGING DEFINITION: The application of tepid water to body’s surface with the use of washcloth to provide cooling measures to a patient with high temperature/ fever.  TEPID SPONGING: EQUIPMENT Basin with tepid water (Temperature 37°C Macintosh/ Rubber sheet Towel Wash cloth Gloves (if patient is on body fluids precaution) Thermometer  To reduce fever by dilating superficial bold vessels, thus releasing heat and lowering body temperature. Improve circulation. TEPID SPONGING: PURPOSE Relieve restlessness. Provide comfort to the client  Hypothermia is condition that occurs when core body Alterations temperature drops below 35ºC. in body Physiologic mechanisms of hypothermia are: temperature § Excessive heat loss (Low body § Inadequate heat production to counteract heat loss temperature) § Impaired hypothalamic thermoregulation The clinical signs of hypothermia: 1. Decreased body temperature, pulse, and respiration 2. Severe shivering (rigor) 3. Feelings of cold and chills 4. Pale, cool skin 5. Hypotension 6. Decreased urinary output 7. Lack of muscle coordination 8. Disorientation 9.

Radial pulse can be taken on either wrist. Use the tip of the index and third fingers of the other hand to feel the pulse in the radial artery between the wrist bone and the tendon on the thumb side of thewrist. Apply just enough pressure to feel each beat. Do not push too hard if not it will block the blood flow. Watch the second hand using watch and count how many times you feel the pulse. Record the pulse rate.  BRACHIAL PULSE The brachial pulse can be located by feeling the bicep tendon in the area of the antecubital fossa. Move the pads of three fingers medial (about 2 cm) from the tendon and about 2–3 cm above the antecubital fossa to locate the pulse.  Find the artery on one side of neck near CAROTID windpipe. Carotid pulse can be taken on either side of neck. PULSE Put the tip of index and long finger in the groove of neck along your windpipe to feel the pulse in your carotid artery. Do not press on the carotid artery on both sides of neck at the same time. This may cause to feel lightheaded or dizzy, or possibly faint. Apply just enough pressure to feel each beat. Do not push too hard or it will block the blood flow. Watch the second hand on watch as you count how many times you feel your pulse. Record pulse rate.  APICAL PULSE Ask client to lie down on his/her back or turned slightly to the left. Use fingers to locate the apical pulse at 5th ICS (adult), 4th ICS (infant/ young child) Apply the end of the stethoscope (either the bell or the diaphragm) to client’s chest. Listen for up to 60 seconds. Remove the stethoscope from your chest.  FEMORAL PULSE Cover the genitalia with a sheet and slightly abduct the thigh. Press deeply, below the inguinal ligament and about midway between symphysis pubis and anterior superior iliac spine. Use two hands one on top of the other to feel the femoral pulse Record the pulse.  In a seated or lying position, slightly bend the leg at the knee, but not so bent that the POPLITEAL foot is flat on the floor. Place the hands around the front of the PULSE knee so your fingers are on the back portion of the knee. Find the fleshy middle portion of the back middle of the knee. Press with increasing pressure until you feel a pulsation in the back of the knee. The pulsation will feel like a heartbeat, usually steady and even in nature. Sometimes you may have to press very deep into the popliteal fossa to feel the pulse. Some people have a lot of tissue on the back of their knee.  DORSALIS PEDIS PULSE The dorsalis pedis artery pulse can be palpated lateral to the extensor hallucis longus tendon (or medially to the extensor digitorum longus tendon) on the dorsal surface of the foot, distal to the dorsal most prominence of the navicular bone which serves as a reliable landmark for palpation. POSTERIOR TIBIAL ARTERY HOW TO CHECK PULSE RATE?  PRE-PROCEDURE Greet and explain procedure to the patient  PRE-PROCEDURE Provide privacy and perform hand hygiene  During- PROCEDURE Select pulse point and position patient appropriately  During- PROCEDURE Place 2 or 3 middle fingers tips lightly and squarely over the pulse site. During- PROCEDURE Palpate and count pulsation for 1 minute  Post-PROCEDURE Inform patient about findings  POST PROCEDURE Perform hand hygiene POST PROCEDURE 4- Inform SRN or doctor if it is an abnormal result  POST PROCEDURE Document reading  Variation in Heart Rate (Tachycardia) A rapid heartbeat more than 100 bpm (heart exceed normal range) Variation in Heart Rate (Bradycardia) A slow heartbeat less than 60 bpm (heart below normal range)  Radial pulse Demonstration video Pulse taking Carotid pulse Apical pulse Femoral pulse, https://youtu.be/nhAz84 Popliteal pulse srBvg Dorsalis pedis pulses RESPIRATION RATE (RR)  RESPIRATION The exchange of oxygen and Two separate carbon dioxide in process the body Mechanical chemical  Respiration: Mechanical Mechanical Pulmonary ventilation; breathing Ventilation: Active movement of air in and out of the respiratory system Conduction Movement through the airways of the lung MECHANICS AND REGULATION OF BREATHING During inhalation the diaphragm contracts the ribs move upward and outward, and the sternum moves outward, thus enlarging the thorax and permitting the lungs to expand. During exhalation The diaphragm relaxes, the ribs move downward and inward, and the sternum moves inward, thus decreasing the size of the thorax as the lungs are compressed.  Respiration: Chemical Chemical Exchange of oxygen and carbon dioxide Diffusion Movement of oxygen and CO2 between alveoli and RBC Perfusion Distribution of blood through the pulmonary capillaries  RESPIRATORY Respiration is controlled by: respiratory centers in the medulla oblongata and the Pons of the brain and Chemo receptors located centrally in the medulla and peripherally in the carotid and aortic bodies.  RESPIRATORY RATE The number of breaths a person takes per minute. Try to do this as surreptitiously as possible. Observing the rise and fall of the chest while you appear to be taking their pulse. Should be counted at least 30 seconds.  NORMAL Adults 12-20/ min RESPIRATORY Young 20-25/min children RATE Infants Up to 40/min  ASSESSING RESPIRATORY RATE Nurses should be aware of the following before having respiration rate: The client’s normal breathing pattern The influence of the client’s health problems on respirations Any medications or therapies that might affect respirations The relationship of the client’s respiration to cardiovascular function  Age FACTORS AFFECTING Physical activity and Exercise THE RESPIRATORY RATE Stress Pain Fever and metabolic rate Lung Disease & respiratory condition Medications Environmental factors Hormonal factors Sleep  VARIATION IN RESPIRATION RATE Eupnea. Respiratory rate is normally described in breaths per minute, normal in depth and rate called Bradypnea Slow respiration rate less than
