CARDIOHELP System
is the world’s smallest portable heart-lung support system
.It is ideal for use in:
Intensive care units
cardiac catheter laboratory
operating room
trauma room
Furthermore, it is the perfect solution for safe and effective patient transport.
There are, therefore, now new areas of use and treatment possibilities for extracorporeal circulation.

Intensive care medicine:
CARDIOHELP System opens up new treatment options in intensive
care medicine which put far less stress on the patient and are also
comparatively inexpensive. In cases of respiratory failure, the device
provides the oxygen supply.
Further areas of use include:
Acute respiratory distress syndrome (ARDS)
Septic shock

Cardiology:
In the event of cardiogenic shock, a frequent consequence
of a heart attack, it is crucial to provide circulatory support
as quickly as possible. This must be guaranteed until the
body is able to resume this function itself. CARDIOHELP
System
can
prevent
organ
damage
resulting
from
insufficient oxygen supply to the vital organs.
Areas of application include:
Cardiogenic shock
As stand-by or prophylactic support during high risk PCI
As a bridging system (bridge to recovery, bridge to bridge, bridge to decision, etc.), e. g., for myocarditis

Cardiac surgery:
At the end of the 1990s, MAQUET developed the minimized
extracorporeal circulation system (MECC System). Its clinical
use in the operating room led to new applications of
extracorporeal life support (ECLS) which required immediate or
extended circulatory support. This principle has been perfected
with CARDIOHELP System and the compact, integrated
design of the HLS Modules. Thanks to the
system’s mobility,
patients can undergo further therapeutic measures (e. g.,
intensive care) and diagnostic investigations (e. g., CT) during
extracorporeal life support.
The areas of use:
Pre-operative heart-lung support (e. g., cardiogenic shock)
Post-operative heart-lung support (e. g., low cardiac output syndrome)
Emergency medicine:
CARDIOHELP Device weighs in at approx. 11 kg and can
easily be carried by one person and is sufficiently
compact to be used during transport. The system is used
in emergencies to restore and stabilize the
atient’s
cardiopulmonary functions. It may have to be used during
cardiopulmonary resuscitation caused by, amongst others:
Anaphylactic shock
Intoxication
Hypothermia
The individual operating modes and the disposables make theCARDIOHELP life support systemsuitable for all indications where cardiac and/or respiratory support is needed. Thus, the principle of ECLS for supplying the heart and/or lungs with oxygen is now available in new areas as a means of life support and to save lives. During open heart surgery, for example minimal extracorporeal circulation (MECC) with the CARDIOHELP life support system, ECLS is less stressful for the patient than the use of a conventional heart-lung machine. In cases of respiratory failure without cardiac impairment CARDIOHELP provides respiratory assistance with veno-venous ECLS. During veno-arterial ECLS the life support system provides cardiopulmonary support. In cases of severe respiratory failure CARDIOHELP can also be used for pump assisted lung protection (PALP) with extracorporealCO2removalto enable protective ventilation.
Veno-venous ECLS
Respiratory assistance for lung disorders:
This form of ECLSis mostly used when the heart is still able to pump blood through the circulatory system without any additional support, as in the case of acute respiratory failure or a massive pulmonary embolism. The blood is removed from the jugular vein or a femoral vein for enrichment with oxygen, after which it is returned to a vein.
Place of use:ICU Fields of applications:
Respiratory failure without cardiac impairment:
ARDS
Septic shock
Bridge to lung transplant Customer and Patient value:
Little complexity, safe to use and more security due to little to no change of components during entire system run. Special feature:Enables CO2removal and oxygenation for up to 30 days.
Access to Patient:percutaneous cannulation of jugular and femoral veins
DIFFERENT THERAPY APPLICATIONS
WITH CARDIOHELP
Veno-arterial ECLS
Cardiac and respiratory support:
Veno-arterial ECLS is used with patients whose hearts are not adequately supporting the circulation, or have stopped. This occurs with a myocardial infarction (heart attack). It is vitally important to ensure cardiopulmonary support as early as possible to prevent organ damage. Furthermore, the CARDIOHELP life support system can increase thepatient’s chances of survival by enabling examination in the cardiac catheter laboratory and revascularization by means of catheters or cardiac surgery.
Place of use:ICU, Cath. Lab, ER, OR
Fields of application: respiratory and circulatory failure:
Cardiogenic shock
During cardiopulmonary resuscitation
As preventive left ventricular support in the event of low cardiac output During PTCA
In cases of acute cardiac arrest or severe cardiogenic shock during the intervention
As standby during high-risk PTCA
In cases of acute post-infarction VSD Customer and patient value:
One system fits all, from a fast deployable emergency life saving circulatory support system to a long term VAD with oxygenation possibility.
Special feature:for a cardiac support and respiratory assistance up to 30 days
CO2 Removal
Pump Assisted Lung Protection (PALP)
In severe cases of respiratory failure the CARDIOHELP life support system can be used in combination with protective ventilation for pump assisted lung protection (PALP) to reduce the CO2 level in the blood. In these cases, protective ventilation focuses on 6 ml/kg (instead of 12 ml/kg BW) tidal volume within the limits of a certain airway pressure and respiratory rate. These ventilation limits cause higher CO2 levels than normal, which is acceptable in many situations(concept of permissive hypercapnia). However, in some cases complications due to high CO2 levels (acidosis, pulmonary hypertension) occur and some patients need low to normal CO2 levels to protect the brain.
Places of use: ICU Fields of applications:
Severe respiratory failure, e.g. ARDS;
Severe COPD (chronic obstructive pulmonary disease)
Customer and patient value: extracorporeal CO2 removal enables protective ventilation to be used Special feature: allows CO2 removal for up to 30 days of ECLS
Access to patient: percutaneous cannulation of either jugular or subclavian and femoral veins
DIFFERENT THERAPY APPLICATIONS
WITH CARDIOHELP
Revascularization
Minimized Extracorporeal Circulation for cardiac surgery (MECC)
Minimal extracorporeal circulation (MECC) with the CARDIOHELP life support system makes ECLS for cardiopulmonary support during open heart surgery less stressful for the patient than when a conventional heart-lung machine is used. With the compact, integral design of the QUADROX-iR oxygenator-pump module, the priming volume and blood surface contact are kept as small as possible. Combined with the exceptionally small pressure drop plus the BIOLINE Coating of the disposable, trauma is minimized.
Moreover, the CARDIOHELP life support system is an intuitively operated system, which is ready for use in minutes for emergency situations. Thanks to the system’s mobility, the patient can undergo further therapeutic measures and diagnostic investigations during ongoing circulatory support.
Place of use:OR
Procedure:minimally-invasive perfusion system with full support for heart and gas exchange for up to 6 h Fields of application:
On-pump CABG surgery.
Postoperative "low cardiac output" syndrome
Patient transport from and into the cardiac operating room, from the emergency/trauma room, from and into the catheterization laboratory
Customer and Patient Value:minimally invasive, less blood product use¹, shorter stay in ICU² Special feature:no blood to air contact, minimal hemodilution

MODES OF CARDIOHELP
RPM and LPM MODES
The CARDIOHELP can be operated in LPM or RPM mode:
RPM mode (speed control, “revolutions per minute”)
In RPM mode, you can set the pump’s setpoint speed. The
CARDIOHELP operates the pump constantly at the set speed. This
enables the flow to be varied, according to the resistance of the
extracorporeal circulation.
LPM mode (flow control, “liters per minute”)
In LPM mode, you can set the setpoint flow. The CARDIOHELP
operates the pump in such a way that the set flow is maintained.
This enables the speed to be varied, according to the resistance of
the extracorporeal circulation.
To activate the “Global Override” mode, hold down the “safety” button and press the “Global Override” Symbol . . The color of symbol changes .
In the zero flow mode, the CARDIOHELP aims at a flow of 0 l/min by controlling the pump accordingly. In this way, a backflow can be prevented.
The zero flow mode can be activated manually or is activated automatically by backflow prevention.
To activate the zero flow mode, hold down the “safety” button and press the “Zero flow mode” button .
Backflow Prevention
The backflow prevention can detect and react to a backflow of blood. For this, the CARDIOHELP
monitors the blood flow, displays any necessary alarms and activates the zero flow mode automatically, to prevent any backflow.

HLS SET FOR CARDIOHELP
The flow of blood is measured by a flow/bubble sensor.
This means, in one housing we have a combined
measuring tool for the flow and a sensor to detect air
bubbles. A detected air bubble stops immediately the
centrifugal pump (called intervention) to prevent an air
embolism.
The sensor have to be fitted so that the
blood flows in the direction of the arrow on the cover.
NOTE:
Only 3/8” x 3/32” PVC tubes approved for this system.

The transit-time method
The transit-time method exploits the fact that the propagation rate of an ultrasonic signal depends on the flow rate of the carrier medium. Like a swimmer swimming against the current, the ultrasonic signal moves more slowly against the flow direction than in the flow direction of the medium. The transit time of the sonic signals which flow through the medium in flow direction is shorter than the transit time of the sonic signals which flow through it against flow direction. By measuring the difference in flow rate Δt, it is possible to calculate the mean flow rate on the path taken by the ultrasonic impulse.
This process involves transmitting one ultrasonic impulse in flow direction and a second impulse in the opposite direction through the medium. The sensors work alternately as transmitters (Tx) and receivers (Rx).
Since ultrasonic waves also penetrate solid objects, the sensors can be attached to the outer wall of the hose. Therefore measuring is not invasive and inserting the sensors does not require any intrusion into the system.
The blood level in the reservoir is measured by a
capacitive level sensor.
The level pad will be attached to the lowest level limit of
reservoir. If the liquid´s surface falls below this limit, the
CARDIOHELP gives an optical and an acoustical alarm
and stops the pump.
The level pad must be attached with the double-faced
Scotch® tape horizontally to the desired position on the
blood reservoir.
NOTE:
Sensor pad must be replaced after every perfusion.

VENOUS PROBE
Blood measurement Principe:
The probe has three LEDs which irradiate the blood
through the BMU Cell at different wavelengths. An
optical sensor measures Hb and Hct concentration
without contact. A second optical sensor measures the
SvO2 value in the same way.
The temperature T
Venis measured by a non-invasive,
thermopile infrared sensor.
Probe fixation:
For measurement, the probe is connected to the
disposable´s measuring cell.
When the probe is not in use, it is hooked into the
holder on the safety bar to protect the sensors.
