Advanced Study | Respiratory & Airway Part One

Airway & Respiratory Anoxia: Lack of O2 Hypoxia: low levels of O2 to the cells, reduced O2 supply to the cells, leads toanaerobic metabolism> metabolic acidosis> cellular depression> cellular death Treatment: O2, it increases the patient’s ability to compensate for the hypoxia Hypoxemia: insufficient oxygenation of the blood Atelectasis: alveolar collapse Compliance: stiffness or flexibility […]

Respiratory Emergencies | Part Four | Pneumonia & Pulmonary Edema

Pneumonia: acute inflammatory condition of the lungs, Bacterial, fungal or viral, 5th leading cause of death. Group of infections due to many different agents. Disorder of ventilation due to infection of the lung parenchyma >> sometimes atelectasis.

Respiratory Emergencies | Part One

Extremely common: two categories, acute and chronic, both can present as life threatening. Respiratory System: filters, warming. Humidifying and exchanging more than 10,000L of air per day (adult). Upper: mouth, pharynx (nasal ands oral) larynx and vocal cords. Lower: trachea, bronchi, bronchioles and alveoli Respiration: inspiring O2 and exhaling CO2 Ventilation: exchanging CO2 Diffusion: crossing […]
