Respiratory

Disorders of ventilation and gas exchange — from reversible airway obstruction to refractory hypoxemia. The nursing core: recognizing early respiratory decline before it becomes failure.

12 disorders

Asthma & Status Asthmaticus

High-yield in research

Reversible airway obstruction — rescue vs controller logic, and why a silent chest is an emergency.

COPD

COPD High-yield in research

Emphysema and chronic bronchitis — O₂ titration facts vs myths, pursed-lip breathing, exacerbation cues.

Pneumonia

High-yield in research

CAP, HAP, and aspiration — and why confusion may be the only sign in an older adult.

Pulmonary Embolism

PE High-yield in research

Sudden dyspnea with clear lungs — the DVT link and the anticoagulation bridge.

Tuberculosis

TB High-yield in research

Airborne precautions, N95s, sputum-clearance rules, and directly observed therapy.

ARDS

ARDS in research

Refractory hypoxemia from a leaky alveolar-capillary membrane — proning and PEEP.

Respiratory Failure & Oxygen Therapy

in research

Early restlessness vs late cyanosis, and the device-escalation ladder.

Airway collapse in sleep — and the post-op opioid caution.

Pulmonary Hypertension & Cor Pulmonale

in research

High pressure in the lung circuit looping back to right-heart failure.
