BACKGROUND This work presents a generalized technique to estimate pulmonary ventilation-to-volume (v/V) distributions using the multiple-breath nitrogen washout, in which both tidal volume (V T ) and the end-expiratory lung volume (EELV) are allowed to vary during the maneuver. In addition, the volume of the series dead space (v d ), unlike the classical model, is considered a common series uni...

in the present investigation, methanolic extract of mimusops elengi  leaves were evaluated for wound healing activity. entire wound healing process is complex series of events that begins at the moment of injury and can continue for months to years. methanolic extract of mimusops elengi leaves were examined for wound healing activity in the form of ointment by the excision, the incision and dea...

STUDY OBJECTIVE Less than 35% of patients suspected of having pulmonary embolism (PE) actually have PE. Safe bedside methods to exclude PE could save health-care resources and improve access to diagnostic testing for suspected PE. In patients with suspected PE, we sought to determine the sensitivity, specificity, and negative predictive value of (1) a steady-state end-tidal alveolar dead space ...

Pada pasien COVID-19 dengan ARDS terjadi gangguan oksigenasi dan ventilasi. Menurut kriteria Berlin ARDS, diukur PaO2/FiO2, namun tidak mengukur ventilasi alveolar yang dead space dapat akibat kondisi, seperti kerusakan endotel, mikrotrombus, penggunaan ventilator berlebih. Tujuan penelitian ini menganalisis ventilatory ratio (VR) fraction (Vd/Vt) sebagai prediktor mortalitas ARDS. Penelitian a...
