Paracentesis
Abdominal paracentesis can establish the cause of ascites or rule out spontaneous bacterial peritonitis in patients with ascites. Large-volume paracentesis in hemodynamically stable patients with tense or refractory ascites can alleviate discomfort or respiratory compromise. This video demonstrates how to perform the procedure.

Orotracheal Intubation
Emergency orotracheal intubation is indicated in any situation in which definitive control of the airway is needed. Specific indications include cardiac or respiratory arrest, failure to protect the airway from aspiration, inadequate oxygenation or ventilation, and impending or existing airway obstruction. This video demonstrates how to perform orotracheal intubation. Specific indications are discussed, along with contraindications, troubleshooting, and complications.

Central Venous Catheterization
The placement of a central venous line is an essential technique in the treatment of many hospitalized patients. This video demonstrates the placement of a central venous catheter in the internal jugular vein and considers complications and how to avoid them.

Pelvic Examination
The purpose of the pelvic examination is to identify developmental or anatomic abnormalities, infection, neoplasms, tubal pregnancies, ovarian cysts, uterine fibroids, and other conditions or disorders. This video demonstrates how to perform a comprehensive pelvic examination, including an examination of the external genitalia, a Papanicolaou test to screen for cervical dysplasia, a bimanual examination, and a rectovaginal examination.

Positive-Pressure Ventilation with a Face Mask and a Bag-Valve Device
Providing positive-pressure ventilation with a face mask and a bag-valve device can be a lifesaving maneuver. Although seemingly simple, the technique requires an understanding of the airway anatomy, the equipment, and the indications. This video demonstrates the equipment and technique used to provide positive-pressure ventilation with a face mask and a bag-valve device.
