Proportional Assist Ventilation
Proportional Assist Ventilation (PAV) is Mode delivers volume, pressure and flow depend on the patient's demand at a percentage which aims to standardize the patient's WOB (1). It is techniques intended for patients who have worsening lung characteristics and unable to maintain a normal ventilation. Because volume and flow vary the airway pressure during PAV varies, it allows the patient to control respiratory rate, peak inspiratory pressure, inspiratory and expiratory time and tidal volume to vary (2). Also, when PAV is used with CPAP, inspiratory muscle work near of a normal with may prevent or decrease muscle atrophy. It reduces airway

    Pulmonary Airflow Lab Report

    In this experiment, several physiological parameters were observed in three patients before, during, and after moderate exercise. One of these parameters was the pulmonary airflow, which was recorded utilizing an Airflow Transducer. This device measures airflow using slight pressure differences created by the resistance of a screen inside the device. Pulmonary airflow is the rate of movement into and out of the lungs, and is directly proportional to the pressure difference of the intrapulmonary pressure and the atmospheric pressure, and inversely proportional to the resistance of the lungs (elasticity/diameter of air pathways).1 The BIOPAC program then can convert the airflow to volume of air moved. Pulmonary ventilation is the movement of air in and out of the lungs. A more specific measurement of pulmonary airflow is the minute respiratory volume, which measures how much air is moved into and out of the lungs in one minute (tidal volume*breaths per minute).2 Since both deal with a volume moved per time, they are synonymous, although the parameter is referred to as airflow in this report.15E…

    Decreased Lung Compliance Case Study

    In the healthcare setting many clinicians are curious to know how airway pressure release ventilation (APRV) works. Many modes of ventilation have been developed throughout the years that focus on lung recruitment and allows for patients to breathe at a spontaneous rate. However, APRV is one of the many modes that concentrate on providing partial ventilatory assistance to patients with some form of respiratory failure. First, can APRV protect the lungs and reduce the work of breathing? Second, is APRV an effective mode of ventilation for patients that suffer from decreased lung compliance? These are just some of the questions physicians ask themselves when determining a method to ventilate their patients.…

    Multisystem Failure Homeostasis And Pain Management Case Study

    The first priority is to perform a focused assessment to include the patient’s respiratory function, pain, mental status, and any medication the patient has taken. The patient’s airway and ability to breathe and maintain a patent airway becomes the first priority. By asking the patient the four questions of orientation the nurse can assess the patient’s mental status. The patient’s pain can also be assessed quickly by using a numerical value or the Wong-Baker Scale prior to the patient becoming unresponsive, as well as asking the patient for a brief history of her medical condition and any co-morbidities. For the patient’s airway and breathing, the patient should be placed on 15 liters of oxygen with a non-rebreather mask to allow for increased oxygenation and a pulse…

    Respiratory Therapist: A Literature Review

    Traditionally the role of the respiratory therapist has been heavily dictated and rather limited by the physician’s orders. For seemingly as long a respiratory therapy has been a recognized medical discipline, therapist have had to endure working under this physician-directed approach, until recent developments prompted an in-depth look into the overall efficiency of such physician-driven protocols. These developments were an over-utilization of respiratory care and misallocations. It was felt that respiratory procedures could be greatly reduced without increased adverse effects on patient outcomes. (Hess, D.…

This machine is called a continuous positive airway pressure (CPAP). Edinger helps them adjust by having them hold “it to their faces for short periods, then taking naps with it. Gradually, they can manage a full night’s sleep” (Chamberlin, 2008).…

    The Forced vital capacity (FVC) is the total amount that can be forcibly exhaled after inhaling the maximum amount. The Forced expiratory volume (FEV1) is the amount of air that is expelled during the first one second of the FVC test (Banasiak, 2014). Geronimo’s original FEV1 was 1.64L, 55% of predicted, this is considered a moderate obstruction of the airway. After the administration of a bronchodilator Geronimo’s FEV1 improved to 2.2L, 74% of predicted value, an improvement of 34% which now classes Geronimo’s obstruction as mild ; evidence that Geronimo is responding well to treatment with the bronchodilator (Banasiak,…

    Asthma and Patient

    Nursing management for a patient with chronic obstructive pulmonary disease begins with assessment; gathering information from the patient including detailed medical history, present symptoms and evaluate findings of diagnostic tests. Symptoms vary with each patient, but may include chronic cough, clubbing of the fingers, chest tightness, weight loss, cyanosis, difficulty breathing with a higher rate of respirations and difficulty sleeping (Weber, 2008). It is common for patients suffering from difficulty breathing to use their accessory muscles to promote more efficient breathing which in turn causes weakness and fatigue. Patients further along in the disease process often are barrel-chested with kyphosis due to over inflation of the lungs caused by the inability to fully exhale (Bare, Cheever, Hinkle, & Smeltzer, 2010).…
