Effects of drugs on the oxygen dissociation curve-a scoping review.

Purpose: The shape and position of the hemoglobin-oxygen dissociation curve (ODC) is of critical importance in medicine, as it determines the uptake of O in the lungs and the delivery of O to the tissues. Numerous reports have identified affinity-modulating effects of drugs in humans. Such effects may be relevant to conditions such as pulmonary diffusion disorders, peripheral vascular disease, or coronary artery disease.

Low-dose carbon monoxide inhalation to increase total hemoglobin mass and endurance performance: scientific evidence and implications.

Recently, chronic intermittent inhalation of low-dose carbon monoxide (CO) has been postulated as a practice to increase total hemoglobin mass with potential beneficial effects on endurance performance. In this perspective article, we discuss the potential performance enhancing capabilities as well as the safety concerns, which include individual variability in CO response, and acute and chronic health effects. It is also important to note that according to the World-Anti-Doping-Agency (WADA), CO inhalation could fall under "" and therefore could be considered a prohibited method if used as a non-diagnostic tool.

Sex dependent effects of cardiovascular agents on hemoglobin oxygen affinity - An ex-vivo experiment.

Background: Hemoglobin‑oxygen (Hb-O) affinity is an important determinant for oxygen delivery and oxygen extraction. Although cardiovascular agents such as noradrenaline, adrenaline, atropine, milrinone and levosimendan are widely used in intensive care units worldwide, nothing is known about their possible effects on Hb-O affinity.

Methods: In this experimental ex-vivo trial, venous blood samples were taken from 5 male and 6 female volunteers and incubated with the particular cardiovascular agents.

The impact of cannabinoids on methemoglobin formation and hemoglobin oxygen affinity: An ex-vivo study.

The affinity of hemoglobin (Hb) to oxygen (O) influences processes of oxygen delivery and extraction at the tissue level. Despite cannabinoids being utilized or ingested in various ways, their possible impact on Hb-O affinity has barely been studied. This is an experimental ex-vivo trial.
