The Respiratory System
A healthy respiratory system is crucial to an individual’s overall health, and respiratory distress is often one of the first indicators of a life-threatening illness. The function of the respiratory system is to exchange gases between the external air and the body. The lungs are the primary organ of the respiratory system that performs this function.
The lungs take up a large portion of the thoracic cavity and are actually attached to the surface of the thoracic cavity by a sticky pleural membrane. The pleural membrane produces a liquid called surfactant that allows the lung to stick to the

The following list summarizes a few common procedures.
• Pulse Oximetry - Tests the percentage of oxygen in the blood. 95% or more is a normal level, and any less would indicate a lack of perfusion (oxygen circulating around the blood).
• Arterial Blood Gas Levels - A blood sample is
Pulse oximeter used to check his oxygen saturation level, which was 98% on air with no central or peripheral cyanosis. Since Mr Devi, does not seem to have any sign of abnormal respiration. The next assessment is circulation, where there are many physical signs to look for. The colour of the hand and digits, are they blue, pink, pale or mottled. Also need to measure for capillary refill time (CRT) by applying cutaneous pressure for 5 Sec on a fingertip held at heart level of Mr. Devi. The normal value of CRT is usually less than 2 second prolonged CRT suggests poor peripheral perfusion. Measure his Blood Pressure (B/P), count pulse rate by listening to the heart with a stethoscope or palpate peripheral and central pulses, assessing for the presence, rate, quality, regularity and equality. All of this assessment indicates the cardiovascular system in the patient is within the normal range or is there any emergency measures should take (Resus.org.uk 2016). However, Mr Devi’s circulation is a concern because his HR was 110bpm which is higher than normal range, the normal heart beat for adults ranges from 60-100bpm. Also his BP was 190/99mmhg with mean arterial pressure (MAP) of
The movie I’m going to focus on is Baby Boy. Baby Boy is a movie by John Singleton set in California and focusing on a young black man named Jody and the struggles he faces in everyday life. I chose this movie because I can kind of relate to the story being that I’m from California and I’ve seen a lot of the situations presented in the movie. Jody is in his early twenties and has two kids by two different women, Yvette and Peanut. He still lives with his mother and acts like he is still a kid, hence the name of the movie Baby Boy. Yvette considers Jody to be her man but he’s still messing around with his other baby mama Peanut, along with numerous other women. Jody and Yvette are constantly arguing about his infidelity and his
The organs that make up the respiratory system are; nose and nasal cavity, mouth, pharynx, larynx, trachea, bronchi, bronchioles, alveoli, diaphragm and lungs.
The lungs are the main organs in the respiratory system and they facilitate the exchange of oxygen and carbon dioxide when a person breaths.
The pulse is an indication of an individual’s heart rate. When checking for a pulse in the primary survey, begin with palpating the patient’s radial or carotid artery (Basic Patient Care 2012, p. 50). This may reveal a normal (60-100 beats/min), tachycardia (<100 beats/min), bradycardia (> 60 beats/min) or asystole heart rate. Additionally, the capillary refill may also provide details about a patient’s cardiovascular status. This is performed by applying pressure to the nail bed and calculating the time it to takes to refill to a normal color, which should take no more then a few seconds otherwise suggesting capillary closure (Mick J Sanders, 2012, p. 1400). An additional accessory to Circulation is Hemorrhages, these involve more through examinations of the pulse, blood pressure and warmth of peripheries of patients. Additionally, you must thoroughly look for indication of bleeding, specifically in the areas around the chest, abdomen and externally seen by the eye.
The lower respiratory system contains the lower trachea, bronchi, bronchioles and alveoli in the lungs. The bronchi form as the lower part of the trachea and branch into two in the left and right lung. The upper segments of the bronchi have C shaped cartilage rings which keep the bronchi open for airflow. The bronchi divide into smaller bronchioles inside the lungs. They are made up of smooth muscle (without cartilage). The bronchioles continue to divide into alveoli; small grape shaped air sacs. Each alveoli is surrounded by pulmonary capillaries. The function of the alveoli is to perform the exchange of oxygen and carbon dioxide. There are millions of alveoli in the lungs, they have thin walls so the diffusion of oxygen and carbon dioxide can move across the membrane without resistance to the pulmonary capillaries.
The ankle-brachial index test measures the blood flow in your arms and legs. This test also
One such device used, EKG or ECG, which is a computer that uses electrodes to measure the heart potentials. This device measure the P wave (atrial depolarization), QRS wave (ventricle depolarization), and the T wave (ventricle repolarization). ECG will show abnormalities of heart function that will need addressed. They will also do blood tests to look for different cardiac enzymes in the blood. These enzymes include creatine phosphokinase (CPK), lactic dehydrogenase (LDH), and aspartate aminotransferase (AST) which are present when heart tissue becomes necrotic (death). Other blood test include complete blood counts which measure hemoglobin levels, hematocrit (HCT) levels, white blood cell counts (WBCC), lipid level counts, and blood urea nitrogen (BUN) counts
and aerobic endurance. It is measured in ‘milliliters of oxygen used in one minute per kilogram of body weight. Nevertheless, it is important to understand your individual VO2max as it is considered to be the best indicator of aerobic endurance and cardiovascular fitness. The actual measurement is done in ‘milliliters of oxygen used in one minute per kilogram of body weight. By knowing your VO2max, it enables an individual to set realistic goals and assess their improvement over time. Many people who exercise, or want to begin exercising do not understand what specific duration, intensity, or heart rate, would be the most beneficial in achieving the goals set. Thus, by having a clear understanding of VO2max an individual can clarify the specific target heart rates, fat
Haemoglobin determination, or haemoglobinometry, is the measurement of the concentration of haemoglobin in the blood. Haemoglobin's main function in the body is to carry oxygen from the lungs to the tissues and to assist in transporting carbon dioxide from the tissues to the lungs. The formation of haemoglobin takes place in the developing red cells located in bone marrow. Haemoglobin values are affected by age, sex, pregnancy, disease, and altitude.
Vital signs consist of the measurement of patient’s blood pressure, temperature, respiratory rate, heart rate and oxygen saturation (Jarvis 2013). They are routinely measured by nurses to gain a baseline assessment of patient’s state of health, monitor for any fluctuations, recognise changes in patient’s condition and to detect for signs of deterioration (Dougherty and Lister 2008 cited in Phillip et al 2013).
Vital signs that are commonly used for the assessment of a patient’s health include pulse rate, respiration rate, blood pressure, and oxygen saturation. Assessment of the pulse rate is for measurement of the rhythm and circulation of
The infant is given a score of zero if he/ she is not breathing {respiration}, no heartbeat {heart rate} , if the muscles are floppy and loose { muscle tone},
It equals right atrial pressure when flow in the cardiovascular system is absent and is measured experimentally.
Likewise, SaO2 remains normal. The oxygen saturation measures the amount of oxygen molecules bound in the haemoglobin. Even if the the RBCs in the body are inadequate, the oxygen saturation can still be normal since the remaining RBCs can still maintain an adequate amount of haemoglobin
