Abstract:
A biventricular assistance device has been implanted in a young woman for a peripartum cardiac failure. An intended weaning consisted of gradual reloading and exercise training monitored with peak oxygen consumption (VO(2)) and radionuclide-left ventricle ejection fraction. Progressive increase in peak VO(2) during partial assistance occurred more than 2 months, from 10.3 to 19 mL.kg(-1).min(-1). Successful explantation was realized when peak VO(2) exceeded 15 mL.kg(-1).min(-1) and radionuclide-left ventricle ejection fraction was more than 40% during off-pump testing.

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
Assessment of Ventilation I: Respiratory Rate
A Ventilation assessment is critical for monitoring a patient's health status. Respiration, one of the most accessible vital signs, provides insights into the function of numerous body systems and can indicate serious health issues, such as brainstem injuries from head trauma.
Critical Guidelines for Assessing Ventilation:
Special considerations while measuring oxygen saturation
Ensuring accuracy in vital sign recordings while prioritizing patient comfort and minimizing anxiety is important.
Assessment of Respiration
Subjective Assessment: Nurses interview the patient to gather information directly during the subjective assessment. It includes questions about the individual's medical history, medications, and symptoms, focusing on past respiratory conditions like asthma or COPD,...
