STUDY OBJECTIVE The inotropic, lusitropic, and electrophysiologic effects of acute hypercapnia in humans are not known. Although the effects of hypercapnia on the systemic circulation have been well documented, there is still some debate as to whether hypercapnia causes true pulmonary vasoconstriction in vivo. We have therefore evaluated the effects of acute hypercapnia on these cardiac indices and the interaction of hypercapnia with the systemic and pulmonary vascular beds in humans… 

Figures and Tables from this paper

Human pulmonary vascular response to 4 h of hypercapnia and hypocapnia measured using Doppler echocardiography.

The human pulmonary circulatory response to changes in Pco(2) has a slower time course and greater sensitivity than is commonly assumed, and vascular tone in the normal pulmonary circulation is substantial.

Effects of Hypercapnia on Myocardial Blood Flow in Healthy Human Subjects

MBF increased with increasing levels of hypercapnia; MBF at a PETco2 of 60 mm Hg was double that at baseline; and MBF after the administration of adenosine was significantly greater than that with the maximal hypercapnic stimulus.

Effect of acute moderate changes in PaCO2 on global hemodynamics and gastric perfusion

In this small group of stable patients, moderate acute variations in PaCO2 had a significant effect on global hemodynamics, but splanchnic perfusion, assessed by ΔPCO2, did not change, in these conditions, the use of pHi to evaluate gastric perfusion appears unreliable.

Regional pulmonary perfusion patterns in humans are not significantly altered by inspiratory hypercapnia.

Data indicate that hypercapnia of this magnitude does not lead to appreciable changes in the distribution of pulmonary perfusion, and that this may represent an interesting distinction between the hypoxic and hypercapnic regulatory response.

Therapeutic hypercapnia for prevention of secondary ischemia after severe subarachnoid hemorrhage: physiological responses to continuous hypercapnia

It is concluded that 45 min might be the optimum duration for a therapeutic use and may provide an optimal balance between the benefits of hypercapnia and risks of a negative rebound effect after return to normal ventilation parameters.

Elevated PaCO2 levels increase pulmonary artery pressure.

Hypercapnia increased PAP in rabbits ventilated with low or high Vt but this effect was not long-lasting and there was not a statistically significant interaction between the effects of hypercapnia and tidal volume on mPAP.

Ventilatory baroreflex sensitivity in humans is not modulated by chemoreflex activation.

It is concluded that rapid baroreflex unloading during the Oxford maneuver is a potent ventilatory stimulus in healthy volunteers and is unaffected by chemoreflex activation, although the operating point is shifted with hypoxia and hypercapnia.

Carbon Dioxide and the Heart: Physiology and Clinical Implications

Clinically relevant issues are addressed, including the role of increased myocardial tissue PCO2 (PmCO2) in the decline in myocardIAL contractility during coronary hypoperfusion and the increased vulnerability to CO2-induced cardiac depression in patients receiving a &bgr;-adrenergic receptor antagonist or with otherwise compromised inotropic reserve.

Cardiovascular responses to forearm muscle metaboreflex activation during hypercapnia in humans.

It is shown that muscle metaboreflex and hypercapnia interact in healthy humans, reducing vasoconstriction but enhancing SV and HCA and MMA interactions were linearly additive for CO and SV.

Mild hypercapnia improves brain tissue oxygen tension but not diffusion limitation in asphyxial cardiac arrest: an experimental study in pigs

Short term mild hypercapnia post-resuscitation could improve Pbto 2 .



Left ventricular systolic performance during acute hypoxemia.

Although cardiac output increases during hypoxemia, this is due to increases in heart rate but not to any effect on stroke volume, and systolic left ventricular function and myocardial contractility are thus well preserved in normal humans during Hypoxemia.

Abnormal myocardial repolarisation in response to hypoxaemia and fenoterol.

Both hypoxaemia and fenoterol cause myocardial repolarisation abnormalities in man in terms of increased QTc dispersion, but only fenotersol increased the QTC interval.

Adverse effects of hypoxaemia on diastolic filling in humans.

Hypoxaemia significantly impairs relaxation of left and right ventricles in normal humans, and this changes may reflect impairment of intracellular calcium transport secondary to the effects of myocyte hypoxia.

Vasoconstrictor effects of angiotensin II on the pulmonary vascular bed.

The pulmonary vasculature exhibited greater sensitivity to the vasoconstrictor effects of ANGII in comparison with the systemic vasculatures, and the increase in vascular resistance was proportionately greater for the pulmonary compared with systemic vascular bed.

Cardiovascular Effects of Carbon Dioxide in Man

Circulatory responses to administration of carbon dioxide were determined in 41 awake human volunteers during controlled or spontaneous respiration to serve as reference points for measurements of cardiovascular function in normal man, and for studying the modification of the circulatory response to CO2.

Comparative effects of angiotensin II on Doppler parameters of left and right heart systolic and diastolic blood flow.

In conclusion, angiotensin II produced changes in Po ejection parameters consistent with a pressor response in the pulmonary vascular bed, and neither right nor left ventricular diastolic filling were directly affected by angiotENSin II.

The influence of preload and heart rate on Doppler echocardiographic indexes of left ventricular performance: comparison with invasive indexes in an experimental preparation.

Doppler measurements of time to peak and the systolic velocity integral correlated less well with conventional hemodynamic indexes and mean acceleration measured by Doppler echocardiography also correlated very closely with conventional indexes, but was subject to greater interobserver variability.

Effect of hypoxemia on the renin-angiotensin-aldosterone system in humans.

The results indicate that plasma aldosterone falls during hypoxemia despite unchanged PRA, ACE, hepatic blood flow, and adrenal function.
