COVID-19 pandemic raises various challenges faced by health workers in hospitals. This study explored strategies for overcoming challenges in caring for COVID-19 patients at hospitals in Indonesia based on healthcare workers’ experience. In-depth interviews were employed with 28 healthcare workers (physicians and nurses) who were purposively sampled. Data were collected via phone and analysed using the Colaizzi method. Five following challenges were found: difficulties in working with personal protective equipment (PPE), offline training for handling Covid and using PPE not being implemented evenly for all health workers, physical and psychological fatigue, difficulties in carrying out health education and assessment towards patients and families, and limited resources to cope with the COVID-19 pandemic. Meanwhile, some barriers require support from the government, public and hospital managers. The information gained from research on the strategies for caring for COVID-19 patients can contribute to better preparedness for hospitals and health workers facing the COVID-19 pandemic.

Acute respiratory distress syndrome (ARDS) is a syndrome, a combination of clinical and physiological observations that describe a pathological state. The pathogenesis of ARDS is not completely clear and there is no gold standard for diagnosis. ARDS is characterized by non-cardiogenic pulmonary edema, inflammation of the lungs, hypoxemia, and decreased lung compliance. Acute is defined as a symptom that occurs within one week of a known risk factor. Early clinical manifestations are shortness of breath (dyspneu and tachypneu) which then quickly develop into respiratory failure. ARDS was first described in 1967 by Asbaugh, et al., then the AECC made a definition that was finally refined by Berlin's criteria. Berlin's criteria divided the degree of hypoxemia into 3, namely mild, moderate, and severe, based on the arterial PO2 / FiO2 ratio and the need for PEEP (5 cm H2O or more) which can be given via endotracheal tube or non-invasive ventilation. Sepsis, aspiration of fluid or gastric contents, and multipe transfusion (>15 units/24 hours) are associated with a high risk of ARDS. Cases of ARDS related to pulmonary sepsis, such as pneumonia, inhalational trauma, and pulmonary contusions are as much as 46% or non-pulmonary sepsis as much as 33%. ARDS management includes oxygen therapy and supportive therapy, such as hemodynamics, pharmacotherapy, and nutrition. Further studies are still needed to get a good outcome for ARDS patients.

Respiration or breathing is the body’s attempt to meet the needs of O2 in the metabolic process and emit CO2 as a result of intermediary metabolism by lung and respiratory organs together so that the resulting cardiovascular oxygen rich blood. Respiration has three phases: ventilation, diffusion, perfusion. The situation is said to somebody normal lung function if the work process of ventilation, diffusion, perfusion, and the relationship between ventilation to perfusion of the person is in a relaxed state resulted in the partial pressure of arterial blood gas (PaO2 and PaCO2) were normal. Examination of lung function has an important role in assessing a lung function. However, the thing to know that these checks are supporting and quite helpful in making a specific diagnosis. With spirometry examination can be known or determined all the static volume except residual volume and respiratory capacity than the capacity of residual volume that contains components such as total lung capacity and functional residual capacity. Functional residual capacity measured by special methods such as by using the inert gas helium (helium dilution test), N2 washout and bodyplethysmograph. Some static pulmonary function parameters can interpret any kind of disturbance in the lungs. In restrictive disorders in general decreased static lung volumes. While the obstruction interference parameters are quite significant, namely an increase in residual volume (RV), functional residual capacity (FRC) and the ratio of residual volume and total lung capacity (RV/TLC)

Background: Obstructive sleep apnea (OSA) is a state of the occurrence of upper airway obstruction periodically during sleep that causes breathing to stop intermittently, either complete (apnea) or partial (hipopnea). Obesity hypoventilation syndrome (OHS) is generally defined as a combination of obesity (BMI ≥ 30 kg / mc) with arterial hypercapnia while awake (PaCO2 > 45 mmHg) in the absence of other causes of hypoventilation. Purpose: In order for the pulomonologis can understand the pathogenesis and pathophysiology of OSA and its complications. Literature review: Several studies have been expressed about the link between OSA, OHS with respiratory failure disease. Pathophysiology of OSA, OHS in respiratory failure were difficult to detect, can cause respiratory failure disease management becomes less effective. Conclusion: A good understanding can help with the diagnosis and management of the appropriate conduct to prevent complications of respiratory failure associated with OSA.
