Initial assessment and treatment
In the emergency room , a portable chest radiography and arterial bloods with co-oximetery were obtained , the patient was placed on a 2 l/min nasal cannula and given an aerosol treatment with 2.5 mg albutrol sulfate in NC .

X-RAY:
The chest radiograph revealed evidence of hyperinflation ,an increase in vascular marking. And an infiltrated in the RLL.
![Page 12: COPD case presentation by Amnah AlLail](https://reader035.vdocuments.us/reader035/viewer/2022062418/5563b53ed8b42a79028b5057/html5/thumbnails/12.jpg)
The patient was the started on the following regimen .supplemental oxygen at 2 L/min by nasal cannula ,nebulized albutrol sulfate , 2.5 mg ,furosemide ,40 mg. The patient was also started on a prophylactic broad –spectrum antibiotic . The report on the gram stain showed numerous gram-positive diplococci

Over the next hour : the patient's respiratory status continued to
deteriorated despite intervention . Respiratory rate rose to 36/min and paradoxical
movement motion become more pronounced . increasing PaCO2 from the first blood gas are
indicative of increasing ventilatory fatigue . So,
Impending respiratory failure must be assumed

Initial Settings:
On the basic of clinical and laboratory data , a decision was made to assist the patient ventilation.
The patient put on NPPV” bilevel positive airway pressure (bilevel PAP ) “as initiated via nasal mask . The IPAP and EPAP levels were titrated to 15/5 resulting in a Spo2 endpoint of around 90%

The patient was poorly complaint with therapy, removing the mask at regular intervals, complaining of not begging able to get enough air. after 1 hour ,an arterial blood gas was obtained and revealed the following:

On the basis of the worsening ventilatory failure despite non invasive ventalitory support, the patient was intubated with a size 8.5 endotracheal tube , and flow-trigger MV
![Page 19: COPD case presentation by Amnah AlLail](https://reader035.vdocuments.us/reader035/viewer/2022062418/5563b53ed8b42a79028b5057/html5/thumbnails/19.jpg)
Was initiated on the following setting:
Mode: CMVVt: 750 mlRR: 10/minPIF: 55l/min ,resulting in an I:E ratio = 1:4FiO2: 0.40PEEP: 5 cm H2OFlow trigger: 2 L/min

After 30 min, an arterial blood gas was obtained are revealed the following:
PH: 7.36PaCO2: 65 mm Hg

On the basis of the blood gas an order was written to titrate the patient's FiO2>= 92% . No other change were made to the ventilator parameters .albutrol orders were changed to MDI,8 puffs in-line Q4H . The patient was suctioned prn for moderate amounts of thick pale yellow secretion
![Page 22: COPD case presentation by Amnah AlLail](https://reader035.vdocuments.us/reader035/viewer/2022062418/5563b53ed8b42a79028b5057/html5/thumbnails/22.jpg)
Patient Monitoring:
Over the course of the next 72 hours the patient was rested on the ventilator and treated appropriately for his pneumonia and right heart failure . The patient remained alert and cooperative with his care.
A chest radiography done on day three ICU admission demonstrated clearing of the pneumonic process in the RLL.
serum theophylline levels were monitored daily ,average 9 mcg/ml (5-15).

The ventilator setting were adjust appropriately and currently are:
Mode: SIMVVt : 750 mlRR: 6PIF : 55L/min , resulting in an I:E = 1:4FiO2: 0.35PEEP : 5 cm H2OPSV : 7 cm H2OFlow trigger : 2 l/min

The arterial blood gas drawn on ventilator setting shows:
PH: 7.39PaCO2: 57 mm HgPaO2 : 74 mm HgHCO3: 34 mEq/lSaO2 : 94%Hb : 15.5 g/dl

Patient Management:
The patient vital signs have normalized and along with ventilator care, fluid status was normalized
bronchodilator therapy was continued to relive brinchospazim and promote mucociliary clearance .
Antibiotics therapy was continued and adjust on the basis of the culture and sensitivity report.
Secretion volume and consistency have decreased and color has changed from yellow to white

Weaning:
He was placed in the spontaneous breathing mode (CPAP) at an FiO2 of 0.35 with a pressure support at 5 cm H2O and CPAP of 5 cm H2O .After 4 hours spontaneous ventilatory parameters were measured and an arterial gas was obtained.

:complication
On the basis of the patients clinical condition and diagnostic results . he was extubated and placed on 2 L/min O2 via nasal cannula .He was moved to the medical floor later that day . and was subsequently discharge 2 days later after being enrolled in the hospital outpatient rehabilitation program
