Correlation between Oxygen Saturation and Hemoglobin and Hematokrit Levels in Tetralogy of Fallot Patients

Althea Medical Journal, 2016
Background: Hemoglobin and hematocrit levels increase in Tetralogy of Fallot (TOF) but the oxygen saturation declines. Reduced hemoglobin in circulating blood as a parameter of cyanosis does not indicate rising hemoglobin due to the ‘not-working ...

Comparison of the Effect of Remifentanil Plus Atropine with Fentanyl and Remifentanil Alone on Preterm Infants’ Vital Signs in Non-emergency Intratracheal Intubation [PDF]

Iranian Journal of Neonatology, 2022
Background: Intratracheal intubation is associated with many side effects. Different groups of drugs have been used to control these side effects, but there is still no consensus on the most suitable drugs.

Effects of Bilateral Nasal Packing on Oxygen Saturation and Blood Pressure

Journal of Nepal Medical Association, 2017
Introduction: Nasal packing is one of the most common rhinological procedures in ENT practice exerting local in nose and systemic effects. Systemic effects may be due to poor sleep quality, respiratory difficulty, decreased oxygen saturation, circulatory

In vivo hepatic flow distribution by computational fluid dynamics can predict pulmonary flow distribution in patients with Fontan circulation

Scientific Reports, 2023
In Fontan patients, a lung deprived of hepatic blood may develop pulmonary arterio-venous malformations (PAVMs) resulting in shunting, reduced pulmonary vascular resistance (PVR) and decreased oxygenation.

Single-shot photoacoustic microscopy of hemoglobin concentration, oxygen saturation, and blood flow in sub-microseconds

Photoacoustics, 2020
We present fast functional optical-resolution photoacoustic microscopy (OR-PAM) that can simultaneously image hemoglobin concentration, blood flow speed, and oxygen saturation with three-pulse excitation. To instantaneously determine the blood flow speed,

Eigenspectra optoacoustic tomography achieves quantitative blood oxygenation imaging deep in tissues

Nature Communications, 2016
Spectral corruption impedes imaging of blood oxygen saturation. Here Tzoumas et al.describe light fluence in the spectral domain and introduce eigenspectra Multispectral Optoacoustic Tomography to account for wavelength-dependent light attenuation and ...
