How Hooke’s Law Has Led to Advancements in Respiratory Care Essay

He died in London on March 3, 1703. Hooke's reputation in the history of physics was somewhat brought on by the discovery of the law of

The bronchial tubes increase in length and diameter during inhalation. Bronchial tubes decrease in length and diameter during exhalation. Poiseuille’s law can be applied to the lungs when the bronchial tubes become constricted due to an increase in mucus production and can decrease in size. When the bronchial tubes decrease in size and the patient is breathing, it is going to take more pressure to move the air into the swelled bronchi. If the radius of a patient’s bronchial tubes increased by sixteen percent, the pressure to move oxygen into the lungs would double. Therefore, a patient with bronchial smooth muscle constriction of sixteen percent would have to double their driving pressure to keep a constant flow rate. If swelling occurs and the patient does not increase their pressure, the amount of oxygen they are getting to their lungs will decrease. Respiratory therapists can see this taking place in patients with asthma that have excess mucus secretions.

Both rapid, shallow breathing patterns and hypoventilation effect gas exchange. Arterial blood gases will be monitored and changes discussed with provider. Alteration in PaCO2 and PaO2 levels are signs of respiratory failure. Patient’s body position will be properly aligned for optimum respiratory excursion, this promotes lung expansion and improved air exchange. Patient will be suctioned as needed to clear secretions and maintain patent airways. The expected outcome is that the patient’s airway and gas exchange will be maintained as evidence by normal arterial blood gases (Herdman,

The presence of fluid in the alveolar space could potentially cause the lung capacity to be effected as well.

Air escaped from the lung into the pleural space. Eventually, enough air collected in the pleural space to cause the mediastinum to shift twoard the right. The collapsed left lung, increased intrapleural pressure, and rightward shift make it difficult to ventilate A.W.

This "dead space" of air needs to stay in your lungs constantly; otherwise the lung will completely deflate. If the lung has every bit of air sucked out of it, it will collapse and need to be re-inflated.

Respiratory therapy refers to both a subject area within clinical medicine and to a distinct health care profession. During the 20th century, there were many health care fundamental transformations. Here are 10 possible predictions of what may occur in the future of respiratory care: (1) Less focus on raising PaO2 as a primary goal in managing patients with acute hypoxemic respiratory failure. (2) More attention to

Now lets look a tension pneumothorax. A tension pneumothorax is when airs builds up in the pleural space [from a chest injury allowing air to enter but not get out] and cause the lungs to compress and decrease return blood flow to the heart causing shock. Tension pneumothorax is a serious and potential deadly condition that can sometimes be controlled by placing a coated trama pad over the hole to control air going in. Another procedure called needle decompression can be done by ALS providers.

In the field of emergency medicine there are few things that are valued as much as a patent airway. From the very beginning stages of training in emergency care we are taught to monitor for airway, breathing and circulation .A patent airway is a very important part of the ABCs triangle necessary to support life. There are many causes of airway compromise, however we will look at basic foreign body airway obstructions and what we can do to fix them.

Continuous Positive Airway Pressure or CPAP as it is known, uses forced air to keep a patients airway open. It has common uses that most people are familiar with such as sleep apnea. But it also used in emergency and hospitals routinely to treat sicknesses such as congestive heart failure. In this essay I will give a brief history on CPAP, a basic overview of its anatomy and the some of the many uses of CPAP and health benefits.

One of the most common causes of an airway obstruction in unconscious patient's is their tongue. This problem can be overcome by the use of an oropharyngeal airway (OPA) or nasopharyngeal airway (NPA). These airway adjuncts are inserted into the patient's mouth or nostril, and are designed to hold the tongue in a position that prevents it from occluding the airway. Another skill authorized for BLS providers is the use of a bag-valve-mask (BVM). This tool allows EMS personnel to deliver positive pressure ventilations to a patient who is not breathing sufficiently on their own. However, this skill is commonly performed improperly. When using a BVM, an EMS provider must make certain that his patient's airway is patent, and that his head is positioned properly. Furthermore, it is critical that an EMS provider ensures that the mask is maintaining a complete seal around his patient's nose and mouth. Otherwise, pressure needed to force air into the lungs escapes through the unsealed portion of the mask, reducing the effectiveness of the ventilation. Another, more advanced skill used by EMS providers is the performance of an endotracheal

The first ventilator induced lung injury that I want to discuss is pulmonary barotrauma. Pulmonary barotrauma is a lung complication caused by too much positive pressure forced into the lungs by a mechanical ventilator. Pulmonary barotrauma occurs when the alveolar begins to rupture due to elevated transalveolar pressure. Transalveolar pressure is a function of both the tidal volume and the overall compliance of the lungs. Researchers use plateau pressures to get an estimation of transalveolar pressure. Plateau pressures can be used as a tool to help measure for the risk of pulmonary barotrauma. Researchers have discovered that plateau pressures less than 30 cmH2O have shown to reduce the cause of pulmonary barotrauma. Guy W. Soo wrote

robbert hooke was a very interesting man. robert hooke was born in july 28 , 1635 and went to many colloges and studyied most of his life. he discoverd cells when he was in his 40s. he used lenses to see the cells he used blood to see that there is more than just a liquid there. he was not very popular back

A are maintaining a patent airway, ensure adequate ventilation and adequate tissue perfusion. The prevention of complications from the mechanical ventilator by maintaining vent settings, and medication administration; neuromuscular blocking agents (NMBAs) of Norcuron (vecuronium) and Ativan (lorazepam) infusing to help the patient tolerate the vent, and help with adequate oxygenation. The client’s hemoglobin level is low at 8g/dL, indicating this client may need additional blood transfusions to bring the value up to normal range of 14-18g/dL. The initial blood gas had shown the client in metabolic alkalosis most likely due to lack of oxygenation and the client holding on to CO2. Proper oxygenation is a priority in this client because healing could be delayed and further complications from the lack of oxygen are starting to trend. The prevention of secondary infection after abdominal surgery is also a high priority to help ensure the client heals with minimal complications. “Nursing priorities for the patient with artificial airway focus on 1) providing humidification, 2) maintaining cuff management, 3) suctioning, 4) establishing a method of communication and 5) providing oral hygiene” (Urden et al., 2016, p.

Elastic recoil refers to how often the lungs recover after being stretched. Pulmonary elasticity depends mainly on two factors: highly elastic connective tissue in the lungs and alveolar surface tension. If an alveolus starts to collapse, the surrounding alveoli are stretched. By recoiling upon being stretched, these alveoli exert expanding forces on the collapsing alveolus and thereby keep it open.
