Spirometry Lab

Patients had to measure their IC by using an incentive spirometer to measure static lung values. They performed this test for 20 minutes after inhaling 400 mg of salbutamol via a nebulizer. The patients were asked to use the FVC spirometer and told to take a deep breath and then to let the breath out passively. They were then asked to do the same maneuver 2 more times, but the closeness made the study choose the first attempt.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

The act of breathing starts from the mouth. You breathe in air through your mouth and nose, and it travels through the back of your throat and down your wind pipe or trachea. Your trachea the divides itself into air passages called bronchial tubes. For your Lungs to perform at their best these passages needed to be clear during inhaling and exhaling. And free from mucus swelling and inflammation.

Shallow breathing and pain altered this patient’s comfort. Therefore, one of the nursing diagnoses can be stated as “Breathing Pattern, Ineffective r/t pain and anxiety, as evidenced by respiratory depth changes" (Ackley & Ladwig p. 175). We briefly discussed the specifics of incentive spirometry use before initiating the intervention. After return demonstration, the patient was ready to use his incentive spirometer.

Ineffective breathing pattern related to bronchoconstriction as evidenced by decreased SpO2 of 91% and increased respirations of 28 breaths per minute (Pillitteri, 2014, p. 1224).

Martin Wright developed the mechanical peak flow meter in 1959, it has been used to monitor serial lung function in asthmatics because it is inexpensive, compact, easy to use, and it provides an objective measure of lung function (Ayala et.al, 2014, p.84). Moreover, the peak flow meter has evolved since its creation almost 60 years ago, in terms of both size and precision. In addition, patients can be taught to use the peak flow meter and monitor their own lung function to determine when to use different medications as directed by an asthma action plan, which is constructed by the patient’s physician and or caregivers. A Peak flow meter is a portable

The main organs of the respiratory system are the lungs – they are the location where the gas exchange between oxygen and carbon dioxide takes place. The lungs therefore expand when you breathe in, and retract when you breathe out. This is done through the diaphragm – a sheet of muscle that is positioned under the lungs. As one inhales, their diaphragm contracts and moves itself downward, increasing the space for your lungs to expand to. The ribs also move to enlarge the possible area the lungs can expand to. This pressure causes air to be sucked through the body to the lungs. When one exhales, the opposite takes place – the diaphragm moves upwards and returns to normal, allowing the process to happen again.

Spirometry is the most popular lung function test. The patient performs a maximal inhalation and then forcefully exhales as quickly and as long as they are able. The spirometer measures the volume of the air exhaled by patients. These measurements are taken at two intervals. The first measurement is the forced expiratory volume in one second (FEV1), records the volume of air exhaled after one second. The second measurement is taken at the point where the patient has fully exhaled the volume of inhaled air; this measurement is the forced vital capacity (FVC) (Harpreet Ranu et al.,

As we breathe in, the muscles in the chest wall force the thoracic area, ribs and connective muscles to contract and expand the chest. The diaphragm is contracted and moves down as the area inside the chest increases as air enters the lungs. The lungs are forced open by this expansion and the pressure inside the lungs becomes enough that it pulls

Then, while holding my nose exhaled into the mouthpiece of the spirometer, and completely emptying my lungs. I then recorded my vital capacity on the chart. I repeated this twice and averaged out my vital capacity all together. Then I was told to measure my tidal volume. I then proceeded to take normal breaths while holding my nose and exhale normally.

The overarching goal of this experiment was to measure respiratory volumes and capacities using spirometry (Marieb & Smith, 2016). Spirometry is a technique which makes use of a device known as a spirometer in order to determine values for inspiratory reserve volume, tidal volume, expiratory reserve volume, as well as others, and thus has a practical use in the fields of anatomy and medicine (Marieb & Smith, 2016). Consequently, since this experiment deals extensively with the processes involved in respiration, it is essential to have a sufficient level of background information on the anatomy and physiology of the lungs (Marieb & Smith, 2016). The lungs are an essential part of the respiratory system, since their main purpose is to perform

Procedures: Initially, a clean mouthpiece was placed on the tube of the spirometer. Then, the nose clip was put in the subject nods to prevent the air escaping through the nasal passageway. The subject has been asked to take a deep breath and expire all the air in the tube to get the FVC value. This procedure had to be repeated again, and the subject was asked to expire as fast and as hard he/she could to get the FVE1 measurement. Afterwards, this was repeated in supine position. Also, this step was duplicated

The breathing process is a result of the respiratory system. The breathing process starts when we take in oxygen from the air through our nasal or oral cavities. From our nasal or oral cavities oxygen moves through the pharynx, larynx, and trachea into the lungs. There oxygen reaches red blood cells where it is then distributed to the cells in the body. In the alveoli through a process called external respiration, oxygen is exchanged for carbon dioxide and exhaled.

Normal respiration consists of inhalation and exhalation. Inhalation is taking in oxygen and delivering it to all cells in the body and exhalation is picking up carbon dioxide waster product of cells and taking it out. Air travel from the nose or mouth into the larynx into the trachea and ends up in the lungs where oxygen is dropped and carbon dioxide is picked up. Oxygen is really important for cell function and when oxygen is not delivered, cells begin to die. So when process of breathing does not work properly other methods of delivering oxygen are used such as tracheostomy.
