Child Acute Heart Failure
What is shock?
Clinical diagnosis in which the circulation is insufficient to meet the demands of the organs and tissues dependent on it.
Heart generates the force required to propel blood forward into the arterial system.
Volume of blood expelled from each ventricle during systole = stroke volume.
Cardiac output [volume of blood ejected per minute] = Stroke volume x heart rate.
Paedictic shock
Hypovolemia
Cardiac failure
Sepsis
CHD
Pressure is higher in the left side of the heart so there is a hole in the septum. Blood will usually flow from the left to the right. CHD is usually classified according to flow.
Classification of CHD
Increased Pulmonary Blood Flow.
Decreased Pulmonary Blood Flow.
Decreased systemic flow.
Altered Circulation.
The increase in pulmonary blood flow leads to:
Patent ductus arteriosus. [PDA]
Atrial Septal Defect. [ASD]
Ventricular Septal Defect. [VSD]
Atrioventricular Septal Defect. [AVSD]
The primary function is to maintain an adequate delivery of oxygen and nutrients to the tissues to maintain the continued production of ATP [Adenosine Triphosphate] [energy store].
Oxygen delivery is primarily dependent on cardiac function and is sensitive to changes in myocardial contractility, preload and afterload
CO = HR x SV. - Cardiac output is the product of heart rate (HR) and stroke volume (SV)
MAP = CO x SVR - Mean arterial pressure is the product of cardiac output and systemic ventricular resistance
HR and MAP can be assessed at the bedside.
SV can be estimated by assessing peripheral pulse volume and end organ perfusion such as urine output and GCS.
Common clinical signs related to congenital heart diseases.
Dyspnoea/Tachypnoea.
Cyanosis/Pallor.
Growth.
Palpitations.
Oedema.
Fatigue.
Feeding pattern- duration, associated distress, volume taken, stopping to rest, caloric supplementation.
Urine output.
Heart rate, blood pressure.
