Diaphragm Release

The study shows the decrease in mechanical support can be effected by increasing periods of unassisted breathing, alternating unassisted breaths with mechanical breaths, and reduction of the support delivered

Inspiratory muscles relax (diaphragm rises; rib cage descends)  Thoracic cavity volume decreases  Elastic lungs recoil and intrapulmonary volume decreases  pressure increases  Air flows out of lungs down its pressure gradient until Ppul = 0. (Marieb & Hoehn, 2013, p. 817-819)

The diaphragm separates the chest and the abdomen as well as this it has a large role in breathing. The diaphragm moves down when we breathe in which expands the chest cavity making room for air to enter through the nasal cavity or mouth. When we breathe out the diaphragm moves upwards, forcing the chest cavity to reduce in size and pushing the gases in the lungs up and out of either the nose or mouth.

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 diaphragm's job is to help pump the carbon dioxide out of the lungs and pull the oxygen into the lungs. The diaphragm is a sheet of muscles that lies across the bottom of the chest cavity. As the diaphragm contracts and relaxes, breathing takes place. When the diaphragm contracts, oxygen is pulled into the lungs. When the diaphragm relaxes, carbon dioxide is pumped out of the lungs.

During inspiration, the diaphragm and the surrounding muscles contract. The diaphragm moves down increasing the volume of the chest cavity, and the surrounding muscles pull the rib up to allow further increase in volume. This increase of volume decreases the air pressure in the alveoli

Overall the treatment plan to treat Mr. Puff’s nicotine dependency would centre around education, and counselling as this is the least invasive option. Implementing nicotine replacement therapy, bupropion SR or varenicline have been noted to be effective pharmacological interventions for patients with COPD and would be important for Mr. Puff as well (Tonnesen, 2013). Smoking cessation is the most modifiable factor for COPD. Furthermore, it increases the rate of survival and decreases mortality. COPD and smoking are significantly correlated with the progression of the disease process. Smoking cessation allows for the accelerated decline in expiratory volume to be prevented as well. It is therefore the most effective option to halt the advancement

The prevalence of asthma has steadily grown in both the US and world populations, and continues to do so. In the US alone, 25 million people were diagnosed with asthma by 2010 (CDC, 2013). In turn, the need to accurately assess the functionality of a patient’s lung capacity is an essential step to begin diagnosis and treatment of their condition. This paper examines the mechanical peak flow meter, which was crafted for assessing lung function capacity in asthmatic patients. In addition, comparing the advantages and disadvantages of usage of the peak flow meter, as well as the proper usage. Among the various instruments used to assess a patient’s lung capacity, the mechanical peak flow meter is the most widely used and among one of the most precise measurement tools (CDC, 2013).

The information collected in the history was highly suggestive of COPD. One of the best predictors of airflow obstruction was the patient’s smoking history (Qaseem, et al., 2011, pp. 181). According to Qaseem, et al. (2011), the presence of the patient’s smoking history and wheezing on physical examination is indicative of airflow obstruction (pp. 181). Additionally, the patient’s presenting complaint was dyspnea on exertion, which is one of the most commonly presenting complaints in patients with COPD (Boardman, 2013, pp. 446). The chronic nature of the patient’s cough and slow progression of symptoms are consistent with a diagnosis of COPD rather than asthma. Finally, the diminished breath sounds on auscultation is indicative of airflow obstruction and considered to be a reliable finding in the diagnosis of COPD (Boardman, 2013, pp. 447). In addition to the new diagnosis of COPD, the patient also had current diagnoses of hypertension, hyperlipidemia, and osteoarthritis.

This study was designed to evaluate the correlation between the puff size (while smoking a cigarette) and the amount of nicotine being inhaled. The researchers wanted to see if there was compensation in puff volume, for the reduced nicotine yields. To provide an unbiased study, the yields and characteristics of tar, carbon monoxide, taste, and draw were all the same, while the nicotine content varied with different participants. There were high, medium, and low nicotine yields, with 24 participants, 14 male and 10 female. The study was done after an 8-10 period of abstaining from smoking.

Participants in this study performed two types of tasks: chest wall maneuvers and speech breathing activities. The chest wall tasks consisted of many different maneuvers, including isovolume, vital capacity, rib cage capacity, abdominal capacity, and relaxation maneuvers. Isovolume maneuvers were conducted, in which the participant displaced volume back and forth from the abdomen to the rib cage with a closed larynx. In vital capacity maneuvers, the participant inspired maximally from resting expiratory level then expired maximally. The minimum and maximum rib cage volumes during the vital capacity maneuver determined rib cage capacity maneuvers, and abdominal capacity maneuvers consisted of the range of abdominal volumes while the participant held their breath. Lastly, relaxation maneuvers were performed in which the participant completely relaxed the chest wall muscles while keeping their larynx closed. Speech breathing activities consisted of two measures: extemporaneous speech and reading speech. For the extemporaneous speech activity, the participant spoke 10 to 20 breath groups about the topic of his choice. For the reading speech activity, the participant read a 12-sentence

Sometimes when a patient is on the more common form of mechanical ventilation for an extended time or if the patient has undergone respiratory failure, their respiratory muscles have a tendency to become weak. With the use of this biphasic cuirass ventilation method they can have the opportunity to build and strengthen those muscles which, in return, can allow them to be weaned from the ventilator

“The BSL Respiratory Effort Xdcr SS5LB was attached to the Biopac Systems MP36 and then was attached to the participant’s chest, underarms, and above the nipple line” [4]. Respiratory monitoring was done throughout the experiment. The subject was seated upon a Gold’s Gym 390R Cycle Trainer stationary bike. The Nonin Pulse Oximeter was used to monitor oxygen saturation levels in subjects’ blood and to measure changes

The frequent use of accessory muscles can indicate a respiratory problem especially if the patient purses their lips and flare their nostrils when breathing (Publications, 2007).

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
