Background: Corona virus is +ve stranded RNA virus pervasive in most of the atmospheres and towards the end of year 2019 it originated a pandemic as emerging microorganism which started in Wuhan city of China causing mild respiratory illness to severe acute hypoxemic respiratory distress syndrome in humans causing lot of deaths. Thanks to Almighty ALLAH that its virulence has been decreased in recent past in Pakistan due to better government planning and preventive measures. Objective: To manage moderate to severe COVID- 19 patients with pneumonias in HDU/ attached wards with central oxygen supply and to observe peril elements of infection severity, non-improvement and case fatality. Study Design: Descriptive, cross sectional, multicenter and heterogenous study of fifty COVID positive patients. Settings: High Dependency Unit & Isolation (Pulmonology ward) District Head Quarter Hospital Sargodha & Niazi Teaching Hospital (OPD), Sargodha Pakistan. Duration: From 15 May 2020 to 30 June 2020. Methodology: Fifty COVID- 19 patients over eighteen years of age presented with moderate to severe illness were enrolled for management in this study. Patients having +ve RT- PCR test (nasopharyngeal swab) for COVID-19/ CT chest with pneumonias, pyrexia, cough, tachypnoea with or without confusion, coma, dehydration, fits, low oxygen saturation, feeding difficulties, myocardial or renal injuries, raised liver enzymes, dysfunctional coagulation, expeditious disease advancement with respiratory failure (ARDS) were included in this study for management. Results: Every patient was admitted for moderate to severe COVID 19 pneumonias, tachypnoea etc. Eleven patients needed high flow nasal oxygen (HFNO) humidified oxygen or noninvasive ventilation (NIV) and non-rebreather mask and two patients required invasive ventilation, 24 patients (48%) patients had diabetes mellitus with complications, 8 patients (16%) had chronic obstructive airway disease (COAD) or asthma on steroids and hypertension with complications was diagnosed in 6 (12%) patients as well. As a whole two critically ill (one old aged diabetic) patients died over one and a half month of study period. Conclusion: COVID-19 can be a fatal disease especially in patients with old age, chronic illnesses (diabetes, COAD, hypertension and chronic renal failure etc.), immunocompromised states, early detection with management is of great value. This study interprets that early usage of NIV (CPAP and HFNO) diminishes respiratory failure symptoms, worsening of disease and the need for invasive ventilation.

Respiratory failure (RF) is defined as the acute or chronic impairment of respiratory system function to maintain normal oxygen and CO2 values when breathing room air. ‘Oxygenation failure’ occurs when O2 partial pressure (PaO2) value is lower than the normal predicted values for age and altitude and may be due to ventilation/perfusion mismatch or low oxygen concentration in the inspired air. In contrast, ‘ventilatory failure’ primarily involves CO2 elimination, with arterial CO2 partial pressure (PaCO2) higher than 45 mmHg. The most common causes are exacerbation of chronic obstructive pulmonary disease (COPD), asthma, and neuromuscular fatigue, leading to dyspnoea, tachypnoea, tachycardia, use of accessory muscles of respiration, and altered consciousness. History and arterial blood gas analysis is the easiest way to assess the nature of acute RF and treatment should solve the baseline pathology. In severe cases mechanical ventilation is necessary as a ‘buying time’ therapy. The acute hypoxemic RF arising from widespread diffuse injury to the alveolar-capillary membrane is termed Acute Respiratory Distress Syndrome (ARDS), which is the clinical and radiographic manifestation of acute pulmonary inflammatory states.

Chronic obstructive pulmonary disease is a syndrome of progressive airflow limitation caused by abnormal inflammatory reaction of airway and lung parenchyma. Risk factor for development of COPD is a complex interaction of genetic factors and many environmental exposures, with the cigarette smoking being the most common etiological agent.It is a prospective observational comparative study conducted among patient with mild to moderate type 2 respiratory failure, secondary to acute exacerbation of Chronic Obstructive Pulmonary Disease admitted in chest ward department of Respiratory medicine, Late Shri Lakhi Ram Agrawal Memorial Medical College, Raigarh, Chhattisgarh, India for a period of one year from April 2020- April 2021.A total 60 patients were studied. Out of which, 30 patients in study group for whom non-invasive ventilation support along with conventional treatment was given and remaining 30 patients in comparison group, same treatment was given without non-invasive ventilation support. Both groups had similar demographic, clinical, biochemical profile at the time of admission. Distribution of comorbidities, smoking history were similar as shown below in tables. After application of Non-invasive ventilation along with conventional treatment in study group, the result showed that mean hours of NIV use in study group was 27 hours and mean hours of Oxygen use in comparison group was 98 hours.Use of non-invasive ventilation in acute exacerbation of COPD, with mild to moderate type 2 respiratory failure, reduced tachypnoea, tachycardia, after 4 hours. There were improvement in oxygen saturation after 4 hours, improvement in PH also occurred after 4 hours by 0.04. Non-invasive ventilation gives rest to fatigued inspiratory muscle so work of breathing is reduced. It also restores functional and biochemical changes associated with fatigued muscle so all complication were reduced with use of non- invasive ventilation.

Acute hypercapnic respiratory failure in chronic obstructive pulmonary disease can usually be managed initially with medical treatment and non- invasive ventilation. In circumstances where non- invasive ventilation cannot be used or has failed, intubation and invasive ventilation may be lifesaving. The outcome of patients with an exacerbation of COPD requiring invasive ventilation is better than often thought, with a hospital survival of 70-89%. Decisions regarding invasive ventilation made by physicians and patients with COPD are unpredictable and vary with the individual. This article reviews the role of invasive ventilation in exacerbations of COPD to assist decision making.
