A tаll thin 25-yeаr-оld cоllege student wаs admitted tо the ER in moderate distress after suddenly developing a sharp pain in his left lower thoracic region. The pain was exacerbated by deep inspiration and radiated anteriorly, almost to the midline. The patient is mildly dyspneic and has episodes of nonproductive cough that seem to increase the chest pain. His trachea is shifted to the right of the midline. Vital Signs: BP= 150/82, HR= 96 beats/min, and respirations 28 breaths/min and shallow. On room air, his SpO2 was 89%, X-ray revealed a mediastinal shift to the right. The left side of the chest was hyperresonant to percussion, and the breath sounds were described as absent or faint on right side. They patient was placed on 50% venturi maks. ABG: pH 7.53, PaCO2 29 mm Hg, HCO3 21 mEq/L, PaO2 56 mm Hg, and SaO2 92%. CVP 10 mm hg MPAP 22 mm Hg PCWP 4 mm Hg CO 2 L/min PVR 300 dynes/sec/ SVR 700 dynes/sec/ The next step for this patient would be to
